- the interface 7 comprises a data entry module 7 a designed to allow the user 100 to enter a plurality of data useful for performing the exercise (that is to say, operating parameters).
- the interface 7 is designed to allow the user 100 to set a basic pair (or combination) of values relating to predetermined operating parameters and corresponding to a machine 1 operating configuration.
- operating configuration refers to the machine operating mode comprising the incline and movement speed set.
- basic pair refers to a couple of values, each associated with a respective parameter, entered by the user 100 at the start of the exercise session or the single exercise.
- Said parameters preferably comprise the user 100 walking or running speed and the incline of the exercise platform 3 a (that is to say, an angle ⁇ of inclination for it).
- the interface 7 (or the data entry module) is designed to receive from the user 100 data about the desired walking or running speed.
- Said desired walking or running speed ideally corresponds to a speed, in the opposite direction, of movement (that is to say, sliding) of the belt 3 during the exercise.
- the interface 7 (or the data entry module) is designed to allow the user 100 to set the desired incline of the exercise platform 3 a.
- That incline may be expressed as an angle ⁇ relative to the horizontal plane (that is to say, the supporting surface “A”) or, preferably, as a percentage gradient of the exercise platform.
- the interface 7 is associated both with the motor 5 (for setting its speed) and with the actuator 6 (for setting its extension or rotation), preferably by means of a suitable processor 8 .

- the switching unit 14 may be integrated in the interface 7 or it may be positioned separately from it.
- the interface 7 and the switching unit 14 are associated since setting the standard mode rather than the energy saving mode involves a variation in the interface 7 (that is to say, what the interface 7 displays for the user 100 ).
- the processor 8 is simply set up to receive the basic pair of values (belt 3 speed and exercise platform 3 a incline) and is designed to set the motor 5 and the actuator 6 accordingly, that is to say, in such a way that the motor drives the belt 3 at the speed set and translates the actuator 6 by an amount such that it provides the exercise platform with the gradient (or incline) set.
- the processor is programmed to derive a value of a parameter representative of the exercise intensity, with the machine 1 in the basic operating configuration, depending on the basic pair of values.
- said parameter representative of the exercise intensity corresponds to oxygen consumption in the unit of time.
- said parameter may also be other measurements, provided that they are representative (that is to say, correlated with) the exercise intensity, or the intensity of the physical activity of the user while exercising.
- the parameter could be calories burned in the unit of time (as an alternative to or in combination with oxygen consumption).
- calories burned differs from oxygen consumption substantially in terms of a weight factor (i.e.: the weight of the user) with which oxygen consumption is not related.
- the parameter representative of the exercise intensity is preferably oxygen consumption, so that there is no need for a weight sensor or for the user to set his weight before exercising.
- the processor derives (that is to say, calculates) the quantity of oxygen absorbed in the unit of time by the user 100 during the exercise.
- That absorption is commonly known as VO2 (where “V” is the symbol for volume, “O2” for oxygen) and it is higher the more strenuous the exercise is, because the body reacts to greater physical stress by absorbing more oxygen so as to maintain high performance levels.
- oxygen consumption usually means (in this text) a value irrespective of the time spent exercising, that is to say, in the unit of time.
- the oxygen consumption could be calculated as an overall value for the exercise, that is to say, also depending on the exercising time desired by the user.
- evaluations below relating to oxygen consumption in the unit of time may refer in equal measure to overall oxygen consumption for the exercise by means of simple mathematical operations which include the time spent exercising amongst the input parameters.
- the processor 8 is also programmed to calculate, said oxygen consumption value being equal, at least one alternative pair (or combination) of values relating to the same parameters, corresponding to a respective machine 1 operating configuration (alternative operating configuration) which involves lower energy consumption by the motor 5 compared with the basic pair.

- the processor 8 is programmed to supply the user 100 with one or more alternative operating configurations which allow energy saving, that is to say, a reduction in the motor absorbed power, with the same training in the exercise session.
- the above-mentioned alternative pairs are formed by a value relating to the belt 3 movement speed and a value relating to the exercise platform 3 a incline.
- the alternative pairs calculated by the processor 8 have a lower walking or running speed and a higher exercise platform 3 a incline compared with the basic pair set.
- the motor 5 is directly responsible for driving the belt 3 , and consequently the motor energy consumption is directly proportional to the belt 3 movement speed.
- the interface 7 is designed to allow the user 100 to select the machine (alternative) operating configuration corresponding to the alternative pair (or to the alternative pairs) of values.
- the interface 7 is designed to display the alternative pair or alternative pairs to the user 100 .
- the processor 8 is programmed to calculate the alternative pairs of values depending on predetermined percentage reductions in motor 5 energy consumption compared with the energy consumption generated by the basic pair.
- the interface 7 is designed to display the alternative pairs to the user 100 , correlating them with the respective (percentage) reduction in energy consumption.
- the interface 7 presents the user 100 with the alternative pairs which involve an energy saving of 20%, 30% and 40%.
- the term compatible refers to the fact that, if the basic pair requires a particularly high gradient or particularly low speed, the processor will automatically tend to exclude from the alternative pairs those comprising gradient/speed values prohibitive for the user or relating to operating configurations which cannot be achieved by the machine 1 .
- the processor 8 is programmed to keep the walking or running speed preferably outside (far from) a range of between 6.5 km/h and 7.5 km/h since in that range it is not clear if the user must be running or walking (with significant repercussions on the actual VO2 value).
- the interface 7 (and in particular the display 7 b ) comprises an icon 9 associated with each of the alternative pairs of values derived by the processor.
- Said icons 9 can be selected by the user 100 to control (preferably by means of the processor 8 ) the actuator 6 and the motor 5 so as to bring the machine 1 into the operating configuration corresponding to the selected alternative pair.
- a first icon 9 a is correlated with a 20% energy saving
- a second icon 9 b is correlated with a 30% energy saving
- a third icon 9 c is correlated with a 40% energy saving.
- the interface also comprises a fourth icon 9 d correlated with the basic pair of parameters set by the user 100 .
- the interface 7 is associated (by means of the processor 8 ) with the actuator 6 and with the motor 5 .
- the interface sends (preferably by means of the processor 8 or by means of a special control unit) the motor 5 and the actuator 6 signals representative of the belt 3 movement speed (that is to say, the motor 5 operating speed) and the exercise platform 3 a incline (that is to say, the extension of the actuator 6 ).

- the machine 1 (in particular the interface 7 ) comprises a tuning module 10 which can be used by the user 100 , while exercising, to vary the energy consumption of the motor 5 between a maximum value, at which the values of the operating parameters correspond to those of the basic pair, and a minimum value at which, the user 100 oxygen consumption in the unit of time being equal, the incline of the exercise platform 3 a has a predetermined maximum value.
- the processor 8 is designed to receive said motor 5 energy consumption value set by the user 100 , for calculating the corresponding pair of values of the parameters and controlling the motor 5 and the actuator 6 accordingly.
- the tuning module 10 can be used by the user 100 , while exercising, to control the energy consumption of the motor 5 between a minimum energy saving configuration, in which the values of the operating parameters correspond to those of the basic combination, and a maximum energy saving configuration, at which the combination of values is such that, the user oxygen consumption being equal, the power absorbed by the motor is minimized.
- the tuning module 10 is designed to allow the user 100 to continuously vary the energy saving value between two limits.
- the tuning module 10 is associated with the processor 8 in such a way that with each variation in the motor 5 energy consumption (set by the user using the tuning module 10 ), the processor 8 calculates a corresponding pair of belt 3 incline and speed values which keeps the user 100 oxygen consumption (that is to say, VO2) unchanged.
- the tuning module 10 is connected to the motor 5 and to the actuator 6 for controlling them depending on the energy saving configuration set.
- the tuning module 10 is associated with the motor 5 and with the actuator 6 (by means of the processor 8 ) for setting the machine 1 operating configuration in real time after the variation set by the user for the motor energy consumption 5 by means of the tuning module 10 .

- the tuning module 10 is associated with (and more preferably included in) the interface 7 display 7 b and comprises a special icon on the touch screen or a special key.
- the processor 8 is programmed to (continuously) correlate all of the operating parameters described above, that is to say, the user 100 walking or running speed or belt movement speed 3 , the belt 3 exercise platform 3 a incline, the motor energy saving and the user 100 oxygen consumption.
- the interface 7 comprises a plurality of control elements 11 , each associated with a respective parameter, which can be displayed during the exercise and selected by the user 100 for selectively setting the value of the respective parameter.
- the processor 8 is programmed to determine the value of the other parameters depending on the fixed parameter and the guide parameter set by the user 100 and to set the machine 1 to the corresponding operating configuration.

- the user 100 can set the oxygen consumption value, varying the belt 3 speed or incline.

- a second control element 11 b is correlated with the exercise platform 3 a gradient
- a third control element 11 c is correlated with the user 100 oxygen consumption
- a fourth control element 11 d is correlated with the motor energy saving.

- the processor 8 is also programmed for calculating, depending on the values of the parameters of the alternative pair set (gradient and speed), a value for the power saved by the motor compared with the corresponding energy consumption determined by the basic combination of values.
- the processor 8 is designed to calculate both the motor 5 instantaneous absorbed power (or energy consumed during the exercise) and the hypothetical motor 5 absorbed power (energy consumed) if the user 100 had decided to stick to the basic pair of values that was initially set.

- the interface 7 comprises a display box 15 which makes available to the user 100 the above-mentioned saving values (energy and carbon dioxide).
- the real-time display of energy saving and reduced environmental impact of the exercise stimulates the user 100 to make greater use of the energy saving mode offered by the machine 1 .
- the processor 8 is designed to receive as an input the duration of the exercise (or a signal representative of the time) and to calculate, depending on said duration, the motor 5 energy saving value and/or the carbon dioxide saving value for the exercise, for making said value calculated available to the user.
- the processor 8 is programmed to add together the motor 5 energy saving value and/or the carbon dioxide saving value for the exercise with a corresponding overall motor 5 energy saving value and/or carbon dioxide saving value for the previous exercises, for updating the overall value at the end of each exercise.
- the interface 7 is designed to display to each user 100 at the end of each exercise (or exercise session) the overall motor 5 energy saving value and/or the overall carbon dioxide saving value.
- the machine 1 comprises a memory 13 designed to record the overall motor 5 energy saving value and/or the overall carbon dioxide saving value in successive exercise sessions by the same user 100 or different users.
- the memory 13 is associated with the processor 8 for receiving the energy and carbon dioxide saving values at the end of each exercise, for adding them together to obtain the overall values for energy saving (and carbon dioxide not emitted) during the machine 1 lifetime (or during a predetermined period of time, for example one day, one week or one month).

Description
- This invention relates to an exercise machine, preferably of the treadmill type, and a method for performing an exercise, preferably using said machine.
- This invention is applied in particular in the sector of fitness and gym equipment.
- There are prior art exercise machines comprising a belt trained around at least two revolving rollers and forming an exercise platform for a user, allowing the user to walk or run on the spot, commonly known as treadmills.
- Such machines are equipped with a motor for driving at least one of the rollers, for driving the belt at a predetermined speed, usually selected in advance by the user by means of an interface located in front of him.
- Moreover, more high-tech treadmills are equipped with an actuator associated with the belt for angling it relative to the horizontal plane, so that the user has the sensation of running uphill.
- Even the inclination parameter (i.e.: the angle of inclination) can be set by the user with the above-mentioned interface, which is normally designed to perform many functions, both controlling the machine, and providing the user with entertainment while he exercises.
- Consequently, in prior art machines, the user can act independently on the belt movement speed and/or incline depending on his level of tiredness or the training goal.
- Disadvantageously, the prior art machines described above have particularly high energy consumption, especially for operating configurations involving high speed and a low belt incline.
- In fact, a high belt speed corresponds to high energy consumption by the motor associated with it.
- However, said disadvantage is accentuated both by the current economic and environmental situations.
- In particular for gyms, which are supplied with a large number of these machines, the disadvantage in economic terms has a considerable effect on internal budgets.
- The aim of this invention is to provide an exercise machine and a method for performing an exercise which overcome the above-mentioned disadvantages of the prior art.
- In particular, the aim of this invention is to provide an exercise machine which allows the possibility of choosing a type of training with limited energy consumption.
- Said aim is fulfilled by the exercise machine according to this invention, comprising:
-

user 100, allowing the user to walk or run on the spot; - a motor connected to at least one of the rollers and able to be activated to drive the belt;
- an actuator associated with the belt to angle the exercise platform relative to a machine supporting surface by rotation about an axis parallel to the axes of rotation of the rollers;
- an interface designed to allow the user to set a basic pair (or combination) of values for parameters consisting of a belt movement speed and an exercise platform incline; said basic pair of values defining a corresponding basic operating configuration of the machine;
- a processor associated with the motor and with the actuator for controlling them and connected to the interface for receiving the basic pair of values set.
- a belt trained around at least two revolving rollers to form an exercise platform for a
- According to this invention, the machine is characterized in that it comprises a processor programmed for:
-
- estimating a value of a parameter representative of the exercise intensity (preferably oxygen consumption in the unit of time, which the user would consume while performing the exercise) with the machine in a basic operating configuration, depending on the basic pair of values,
- deriving at least one alternative pair of values for the parameters, different to said basic pair of values and corresponding to an exercise intensity (oxygen consumption) equal to the estimated value and to an energy consumption by the machine motor lower than that corresponding to the basic pair of values, the interface being designed to allow the user to select a machine operating configuration corresponding to said at least one alternative pair of values, thus allowing the processor to control the motor and the actuator depending on the operating configuration selected.
- Moreover, the aim of this invention is to provide a method for performing an exercise using an exercise machine which limits its energy consumption.
- According to this invention, that aim is fulfilled by the method for performing an exercise using an exercise machine comprising a belt forming an exercise platform for a user and trained around at least two revolving rollers driven by a motor, allowing the user to walk or run on the spot, characterized in that it comprises the following steps:
-
- setting a basic pair of values for parameters consisting of a belt movement speed and an exercise platform incline;
- estimating a value of a parameter representative of the exercise intensity (preferably oxygen consumption in the unit of time, which the user would consume while performing the exercise) with the machine in the basic operating configuration;
- deriving at least one alternative pair of values for the parameters, different to the basic pair and corresponding to an exercise intensity (oxygen consumption) equal to the estimated value and to an energy consumption by the motor lower than that corresponding to the basic pair of values;
- selection by the user of a machine operating configuration corresponding to said at least one pair of values;
- setting the machine in the corresponding operating configuration.
- Preferably, the method of the invention allows the user to input desired values (in absolute or relative terms) of the energy consumption by the motor, whereby the machine is set to a pair of values which correspond to the input value of energy consumption and to said estimated value of exercise intensity.
- Preferably, said at least one alternative pair of values for the parameters derived is displayed together with information about the energy consumption by the motor corresponding to said pair of values; hence, the user is allowed to perform the selection taking into account the energy consumption by the motor.
- Preferably, the exercise machine of the invention has an interface configured for allowing the user to input desired values (in absolute or relative terms) of the energy consumption by the motor; the processor is programmed for setting to a pair of values which correspond to said input value of energy consumption and to said estimated value of exercise intensity.
- Preferably, said interface is configured for displaying information about the energy consumption by the motor corresponding to said derived at least one alternative pair of values for the parameters, whereby the user is allowed to perform the selection taking into account the energy consumption by the motor.
- This and other features of the invention will become more apparent from the following description of a preferred, non-limiting embodiment of the exercise machine, shown purely by way of example, with reference to the accompanying drawings, in which:
-
FIG. 1 is a schematic side view of an exercise machine according to this invention; -
FIGS. 2 to 5 are views of the machine interface ofFIG. 1 in successive operating modes. - The
exercise machine 1 comprises a supportingframe 2 with abase 2 a resting on the floor and aportion 2 b for supporting auser 100. - The
base 2 a rests on a supporting surface “A” for themachine 1, preferably horizontal. - Along the
base 2 a there is preferably abelt 3 trained around at least two revolvingrollers 4, each roller revolving about its own axis of rotation. - More precisely, the
belt 3 can slide around therollers 4 in such a way as to form an endless moving surface, orexercise platform 3 a. - In other words, the
machine 1 is of the treadmill type. - Preferably, the two
rollers 4 rotate about axes of rotation which are parallel and are aligned in amachine 1 exercise direction “B”. - Consequently, the machine comprises a
front roller 4 a and arear roller 4 b. - In particular, the portion of
belt 3 which extends between the tworollers 4 forms theexercise platform 3 a for theuser 100, allowing the user to walk or run on the spot. - The
exercise platform 3 a forms an exercise surface “C” on which theuser 100 can walk or run. - Preferably, the
belt 3 is made of material with a high friction coefficient (anti-slip), so as to allow optimum grip between the sole of the user's foot and the exercise platform during the exercise. - The
machine 1 comprises driving means associated with thebelt 3 for driving its movement and/or moving it in space. - In particular, the
machine 1 comprises amotor 5 connected to at least one of therollers 4 and able to be activated to drive thebelt 3. - The
motor 5 can be activated to drive the rotation of the above-mentioned roller 4 (or both rollers) at a predetermined speed, so as to allow theuser 100 to walk or run at a predetermined walking or running speed. - Preferably, the
motor 5 is of the electric type. - In other words, the
motor 5 is connected to the mains power supply to draw from the latter the power it needs in order to operate. - Consequently, an increase in the speed of the
rollers 4 corresponds to an increase inmotor 5 energy consumption. - It should be noticed that the
motor 5 energy consumption corresponds to the power that themotor 5 draws from the mains (hereinafter referred to as absorbed power). - The
machine 1 also comprises anactuator 6 associated with thebelt 4 to angle theexercise platform 3 a relative to a surface “A” supporting themachine 1, by rotation about an axis parallel with the axes of rotation of therollers 4. - In other words, the
actuator 6 lifts oneroller 4 relative to the other (thefront roller 4 a relative to therear roller 4 b), keeping the axes of rotation parallel with each other to simulate an upward slope. - Consequently, the exercise surface “C” can be angled relative to the surface “A” supporting the
machine 1, allowing theuser 100 the most diverse exercising possibilities. - The
actuator 6 acts on thebelt 3, making it rotate, or simply lifting thefront roller 4 a and obtaining a rotation of theexercise platform 3 a about therear roller 4 a. - Alternatively, the lifting may occur by means of rototranslation, that is to say, movement of the rear roller along the horizontal plane and the front roller along the vertical plane (or an angled plane).
- Preferably, the
actuator 6 is associated with thefront roller 4 a in such a way as to provide a stable support for thebelt 3 even when theexercise platform 3 a is set at an angle. - The
actuator 6 may be of the linear or curved type. - In the embodiment illustrated, the
actuator 6 is positioned at thefront roller 4 a and has a substantially vertical operating direction. - It should be noticed that, in the embodiment illustrated, the
entire belt 3 is angled relative to the supporting surface “A”. - However, in alternative embodiments, a system of rollers and return devices could be used to allow angling only for the exercise platform.
- In the embodiment illustrated, the
actuator 6 is of the hydraulic/pneumatic type. - In alternative embodiments, the actuator may be of the electric or electromechanical type.
- To allow the
user 100 to interact with themany machine 1 functions, themachine 1 comprises aninterface 7 positioned in front of (or at the side of) auser 100 exercising position (that is to say, a position adopted by theuser 100 while exercising). - In this way, the
user 100 can easily reach theinterface 7 even during the most demanding exercises. - More precisely, the
interface 7 is positioned at a height at which it is particularly easy to reach and view. - In the embodiment illustrated, the
interface 7 is immediately in front of thefront roller 4 a, at a height greater than that of the front roller. - Preferably, the
interface 7 comprises adisplay 7 b (or screen) and a control panel, more preferably a touch-screen. - Alternatively, the control panel may be a keyboard which is separate from the
screen 7 b. - The
interface 7 comprises adata entry module 7 a designed to allow theuser 100 to enter a plurality of data useful for performing the exercise (that is to say, operating parameters). - Preferably, the
interface 7 is designed to allow theuser 100 to set a basic pair (or combination) of values relating to predetermined operating parameters and corresponding to amachine 1 operating configuration. - The term “operating configuration” refers to the machine operating mode comprising the incline and movement speed set.
- The expression “basic pair” refers to a couple of values, each associated with a respective parameter, entered by the
user 100 at the start of the exercise session or the single exercise. - Said parameters preferably comprise the
user 100 walking or running speed and the incline of theexercise platform 3 a (that is to say, an angle α of inclination for it). - More precisely, the interface 7 (or the data entry module) is designed to receive from the
user 100 data about the desired walking or running speed. - Said desired walking or running speed ideally corresponds to a speed, in the opposite direction, of movement (that is to say, sliding) of the
belt 3 during the exercise. - Consequently, hereinafter reference is made to one or the other with the same meaning, unless expressly otherwise indicated.
- Moreover, the interface 7 (or the data entry module) is designed to allow the
user 100 to set the desired incline of theexercise platform 3 a. - That incline may be expressed as an angle α relative to the horizontal plane (that is to say, the supporting surface “A”) or, preferably, as a percentage gradient of the exercise platform.
- It should be noticed that hereinafter, for simplicity, reference is made to the
belt 3 incline rather than theexercise platform 3 a incline, since that is more intuitive and in line with the embodiment illustrated. - Therefore, the
interface 7 is associated both with the motor 5 (for setting its speed) and with the actuator 6 (for setting its extension or rotation), preferably by means of asuitable processor 8. - The above-mentioned
processor 8 is in fact set up to receive the data from theinterface 7 and is designed to process them so as to control the driving means. - In other words, the
processor 8 is associated with themotor 5 and with theactuator 6 for controlling them. - Therefore, the
processor 8 is set up to receive data about the walking or running speed and the incline (angle α) set by theuser 100 and it is designed to set (or activate) themotor 5 and/or theactuator 6 accordingly. - In other words, the
processor 8 is connected to the interface for receiving data representative of the basic pair of values set. - According to this invention, the
machine 1 can be selectively switched between an energy saving mode and a standard mode. - For that purpose, the
machine 1 comprises aswitching unit 14 which can be selected by theuser 100 for setting themachine 1 either to the energy saving mode or to the standard mode. - The switching
unit 14 may be integrated in theinterface 7 or it may be positioned separately from it. - In spite of that, the
interface 7 and the switchingunit 14 are associated since setting the standard mode rather than the energy saving mode involves a variation in the interface 7 (that is to say, what theinterface 7 displays for the user 100). - In the standard mode, the
processor 8 is simply set up to receive the basic pair of values (belt 3 speed andexercise platform 3 a incline) and is designed to set themotor 5 and theactuator 6 accordingly, that is to say, in such a way that the motor drives thebelt 3 at the speed set and translates theactuator 6 by an amount such that it provides the exercise platform with the gradient (or incline) set. - In contrast, in the energy saving mode, the processor is programmed to derive a value of a parameter representative of the exercise intensity, with the
machine 1 in the basic operating configuration, depending on the basic pair of values. - Preferably, said parameter representative of the exercise intensity corresponds to oxygen consumption in the unit of time.
- However, said parameter may also be other measurements, provided that they are representative (that is to say, correlated with) the exercise intensity, or the intensity of the physical activity of the user while exercising. For example, the parameter could be calories burned in the unit of time (as an alternative to or in combination with oxygen consumption).
- It should be noticed that calories burned differs from oxygen consumption substantially in terms of a weight factor (i.e.: the weight of the user) with which oxygen consumption is not related.
- For that reason, the parameter representative of the exercise intensity is preferably oxygen consumption, so that there is no need for a weight sensor or for the user to set his weight before exercising.
- Therefore, in the following description reference is only made to oxygen consumption, without thereby limiting the scope of the invention.
- Therefore, having set the desired operating configuration (i.e.: the
belt 3 movement speed and theexercise platform 3 a incline) the processor derives (that is to say, calculates) the quantity of oxygen absorbed in the unit of time by theuser 100 during the exercise. - That absorption is commonly known as VO2 (where “V” is the symbol for volume, “O2” for oxygen) and it is higher the more strenuous the exercise is, because the body reacts to greater physical stress by absorbing more oxygen so as to maintain high performance levels.
- It should be noticed that the expression “oxygen consumption” usually means (in this text) a value irrespective of the time spent exercising, that is to say, in the unit of time.
- However, in alternative embodiments the oxygen consumption could be calculated as an overall value for the exercise, that is to say, also depending on the exercising time desired by the user.
- However, it should be noticed that the evaluations below relating to oxygen consumption in the unit of time may refer in equal measure to overall oxygen consumption for the exercise by means of simple mathematical operations which include the time spent exercising amongst the input parameters.
- The
processor 8 is also programmed to calculate, said oxygen consumption value being equal, at least one alternative pair (or combination) of values relating to the same parameters, corresponding to arespective machine 1 operating configuration (alternative operating configuration) which involves lower energy consumption by themotor 5 compared with the basic pair. - Preferably, the
processor 8 is programmed to calculate, said oxygen consumption value being equal, a plurality of alternative pairs (or combinations) of values relating to the same parameters, each corresponding to arespective machine 1 alternative operating configuration which involves lower energy consumption by themotor 5 compared with the basic pair. - In other words, the
processor 8 is programmed to supply theuser 100 with one or more alternative operating configurations which allow energy saving, that is to say, a reduction in the motor absorbed power, with the same training in the exercise session. - The above-mentioned alternative pairs are formed by a value relating to the
belt 3 movement speed and a value relating to theexercise platform 3 a incline. - In particular, the alternative pairs calculated by the
processor 8 have a lower walking or running speed and ahigher exercise platform 3 a incline compared with the basic pair set. - In fact, as already indicated, the
motor 5 is directly responsible for driving thebelt 3, and consequently the motor energy consumption is directly proportional to thebelt 3 movement speed. - However, a simple reduction in speed would involve not just a reduction in
motor 5 energy consumption, but also a reduction in VO2 (oxygen consumption). - With regard to that, it should be noticed that with an increase in the gradient (or incline of the
exercise platform 3 a) the exercise becomes more difficult, requiring a higher VO2. - As a result, to reduce
motor 5 energy consumption while keeping the oxygen consumption in the unit of time unchanged, it is necessary to reduce thebelt 3 movement speed while at the same time increasing theexercise platform 3 a incline. - According to the invention, the
interface 7 is designed to allow theuser 100 to select the machine (alternative) operating configuration corresponding to the alternative pair (or to the alternative pairs) of values. - Preferably, the
interface 7 is designed to display the alternative pair or alternative pairs to theuser 100. - The
processor 8 is programmed to calculate the alternative pairs of values depending on predetermined percentage reductions inmotor 5 energy consumption compared with the energy consumption generated by the basic pair. - Advantageously, the
interface 7 is designed to display the alternative pairs to theuser 100, correlating them with the respective (percentage) reduction in energy consumption. - In the embodiment illustrated, the
interface 7 presents theuser 100 with the alternative pairs which involve an energy saving of 20%, 30% and 40%. - However, it is possible to program the interface to display any pair for any energy saving compatible with the basic combination set by the
user 100. - The term compatible refers to the fact that, if the basic pair requires a particularly high gradient or particularly low speed, the processor will automatically tend to exclude from the alternative pairs those comprising gradient/speed values prohibitive for the user or relating to operating configurations which cannot be achieved by the
machine 1. - For example, the
processor 8 is programmed to keep the walking or running speed preferably outside (far from) a range of between 6.5 km/h and 7.5 km/h since in that range it is not clear if the user must be running or walking (with significant repercussions on the actual VO2 value). - With regard to that, the interface 7 (and in particular the
display 7 b) comprises anicon 9 associated with each of the alternative pairs of values derived by the processor. -
Said icons 9 can be selected by theuser 100 to control (preferably by means of the processor 8) theactuator 6 and themotor 5 so as to bring themachine 1 into the operating configuration corresponding to the selected alternative pair. - In particular, a
first icon 9 a is correlated with a 20% energy saving, asecond icon 9 b is correlated with a 30% energy saving and athird icon 9 c is correlated with a 40% energy saving. - Preferably, the interface also comprises a
fourth icon 9 d correlated with the basic pair of parameters set by theuser 100. - Therefore, the
interface 7 is associated (by means of the processor 8) with theactuator 6 and with themotor 5. - In fact, once the
user 100 has selected the preferred alternative combination (using the corresponding icon 9), the interface sends (preferably by means of theprocessor 8 or by means of a special control unit) themotor 5 and theactuator 6 signals representative of thebelt 3 movement speed (that is to say, themotor 5 operating speed) and theexercise platform 3 a incline (that is to say, the extension of the actuator 6). - Preferably, the
processor 8 is programmed to calculate a trend (that is to say, substantially continuous operation) of theexercise platform 3 a incline value depending on the reduction in the speed of thebelt 3. - In other words, the
processor 8 correlates the gradient and speed parameters substantially continuously. - As a result, for each
belt 3 movement speed value (and therefore eachmotor 5 energy consumption value), theprocessor 8 can calculate thecorresponding exercise platform 3 a gradient value which keeps the oxygen consumption unchanged. - In light of this, the machine 1 (in particular the interface 7) comprises a
tuning module 10 which can be used by theuser 100, while exercising, to vary the energy consumption of themotor 5 between a maximum value, at which the values of the operating parameters correspond to those of the basic pair, and a minimum value at which, theuser 100 oxygen consumption in the unit of time being equal, the incline of theexercise platform 3 a has a predetermined maximum value. - For that purpose, the
processor 8 is designed to receive saidmotor 5 energy consumption value set by theuser 100, for calculating the corresponding pair of values of the parameters and controlling themotor 5 and theactuator 6 accordingly. - In other words, the
tuning module 10 can be used by theuser 100, while exercising, to control the energy consumption of themotor 5 between a minimum energy saving configuration, in which the values of the operating parameters correspond to those of the basic combination, and a maximum energy saving configuration, at which the combination of values is such that, the user oxygen consumption being equal, the power absorbed by the motor is minimized. - More precisely, the
tuning module 10 is designed to allow theuser 100 to continuously vary the energy saving value between two limits. - The
tuning module 10 is associated with theprocessor 8 in such a way that with each variation in themotor 5 energy consumption (set by the user using the tuning module 10), theprocessor 8 calculates a corresponding pair ofbelt 3 incline and speed values which keeps theuser 100 oxygen consumption (that is to say, VO2) unchanged. - Moreover, the
tuning module 10 is connected to themotor 5 and to theactuator 6 for controlling them depending on the energy saving configuration set. - In other words, the
tuning module 10 is associated with themotor 5 and with the actuator 6 (by means of the processor 8) for setting themachine 1 operating configuration in real time after the variation set by the user for themotor energy consumption 5 by means of thetuning module 10. - For example, the
tuning module 10 comprises a lever or a push-button panel positioned on themachine 1 frame, preferably close to theinterface 7. - However, preferably, the
tuning module 10 is associated with (and more preferably included in) theinterface 7display 7 b and comprises a special icon on the touch screen or a special key. - The
processor 8 is programmed to (continuously) correlate all of the operating parameters described above, that is to say, theuser 100 walking or running speed orbelt movement speed 3, thebelt 3exercise platform 3 a incline, the motor energy saving and theuser 100 oxygen consumption. - Advantageously, in this way, if there is a variation in each of said parameters the corresponding values of the remaining parameters are available.
- With regard to that, the
interface 7 comprises a plurality ofcontrol elements 11, each associated with a respective parameter, which can be displayed during the exercise and selected by theuser 100 for selectively setting the value of the respective parameter. - Advantageously, that allows the
user 100 to set the value of a first parameter (or fixed parameter) as required and at the same time to vary the value of a second parameter (or guide parameter), obtaining the simultaneous display of the corresponding variation of the values of the remaining parameters. - More precisely, the
processor 8 is programmed to determine the value of the other parameters depending on the fixed parameter and the guide parameter set by theuser 100 and to set themachine 1 to the corresponding operating configuration. - For example, the
user 100 can, during the exercise, set a desired energy saving value (preferably a percentage) and vary theexercise platform 3 a incline, increasing the oxygen consumption to make the exercise more challenging. - Alternatively, the
user 100 can set a desiredbelt 3 incline value, since he does not think he can exceed that value. - Also, the
user 100 can set the oxygen consumption value, varying thebelt 3 speed or incline. - Advantageously, in this way the
user 100 has full control of the operating and energy consumption parameters and can manage them as desired. - In the preferred embodiment, the
control elements 11 form acontrol panel 12 which can be displayed on theinterface 7 screen during the exercise or alternatively can be reduced to an icon. - In particular, a
first control element 11 a is correlated with thebelt 3 movement speed, asecond control element 11 b is correlated with theexercise platform 3 a gradient, athird control element 11 c is correlated with theuser 100 oxygen consumption and afourth control element 11 d is correlated with the motor energy saving. - It should be noticed that in such a case the
fourth control element 11 d corresponds to thetuning module 10. - Preferably, the
processor 8 is also programmed for calculating, depending on the values of the parameters of the alternative pair set (gradient and speed), a value for the power saved by the motor compared with the corresponding energy consumption determined by the basic combination of values. - In other words, the
processor 8 is designed to calculate both themotor 5 instantaneous absorbed power (or energy consumed during the exercise) and thehypothetical motor 5 absorbed power (energy consumed) if theuser 100 had decided to stick to the basic pair of values that was initially set. - At the same time, the
processor 8 calculates the difference (in absolute and/or percentage terms) between the above-mentioned two values and sends a signal representative of that difference to theinterface 7, which is designed to display the energy saving value for theuser 100 to see. - Moreover, the
processor 8 is programmed to calculate, depending on the values of the parameters of the alternative combination set, a value representative of the amount of the carbon dioxide saving (i.e.: not emitted) after setting the alternative combination, compared with the amount of carbon dioxide that would hypothetically have been emitted into the environment if the basic combination had been set. - In other words, and similarly to what was already indicated, the
processor 8 calculates the difference (in absolute and/or percentage terms) between the value of carbon dioxide emitted in actual operating conditions and the value of carbon dioxide that would hypothetically have been emitted into the environment if theuser 100 had decided to stick to the basic combination of values that was initially set. - The
processor 8 also sends a signal representative of that difference to theinterface 7, which is designed to display to theuser 100 the value of carbon dioxide not emitted into the environment thanks to setting the energy saving mode. - In the embodiment illustrated, the
interface 7 comprises adisplay box 15 which makes available to theuser 100 the above-mentioned saving values (energy and carbon dioxide). - Advantageously, the real-time display of energy saving and reduced environmental impact of the exercise stimulates the
user 100 to make greater use of the energy saving mode offered by themachine 1. - Moreover, preferably, the
processor 8 is designed to receive as an input the duration of the exercise (or a signal representative of the time) and to calculate, depending on said duration, themotor 5 energy saving value and/or the carbon dioxide saving value for the exercise, for making said value calculated available to the user. - More preferably, the
processor 8 is programmed to add together themotor 5 energy saving value and/or the carbon dioxide saving value for the exercise with a correspondingoverall motor 5 energy saving value and/or carbon dioxide saving value for the previous exercises, for updating the overall value at the end of each exercise. - For that purpose, the
interface 7 is designed to display to eachuser 100 at the end of each exercise (or exercise session) theoverall motor 5 energy saving value and/or the overall carbon dioxide saving value. - Therefore, the
machine 1 comprises amemory 13 designed to record theoverall motor 5 energy saving value and/or the overall carbon dioxide saving value in successive exercise sessions by thesame user 100 or different users. - More precisely, the
memory 13 is associated with theprocessor 8 for receiving the energy and carbon dioxide saving values at the end of each exercise, for adding them together to obtain the overall values for energy saving (and carbon dioxide not emitted) during themachine 1 lifetime (or during a predetermined period of time, for example one day, one week or one month). - Moreover, the
memory 13 is designed to provide theprocessor 8 with said overall value in such a way that theprocessor 8 can add to the overall saving value of the previous sessions the instantaneous saving value of the exercise in progress. - In light of this, the
interface 7 is designed to display to eachuser 100 during each exercise session theoverall motor 5 energy saving value and/or the overall value of carbon dioxide not emitted. - The expression “overall value” therefore refers to the sum of the energy saving (and carbon dioxide not emitted) values of the
machine 1 thanks to the energy saving mode during its lifetime. - Advantageously, that makes the user aware of the environmental effectiveness of the energy saving mode.
- This invention also relates to a method for performing an exercise using the
exercise machine 1, comprising the steps of setting a desired basic pair of operating parameters; the parameters comprising a walking or running speed and anexercise platform 3 a incline, and deriving theuser 100 oxygen consumption value depending on said basic combination of parameters. - More precisely, the method also comprises the step of estimating the oxygen consumption value in the unit of time, which the
user 100 would consume by performing an exercise with themachine 1 in the basic operating configuration, depending on the basic pair of values. - In other words, it comprises a step of calculating, said oxygen consumption value being equal, a plurality of alternative combinations of values each corresponding to a respective machine operating configuration which involves lower energy consumption by the
motor 5 compared with the basic combination. - Moreover, the method comprises deriving at least one alternative pair of values for the parameters, different to the basic pair and corresponding to an oxygen consumption equal to the estimated value and to an energy consumption by the
motor 5 lower than that corresponding to the basic pair of values. - More precisely, the method comprises deriving a plurality of alternative operating configurations which allow energy saving, that is to say, a reduction in the motor absorbed power, with the same training in the exercise session.
- After that, the
user 100 selects a machine operating configuration corresponding to one of the pairs of values and the machine is set to the corresponding operating configuration. - Preferably, the alternative combinations are displayed for the
user 100 who can select the preferred alternative combination. - The method described above may be implemented at the start of an exercise session or during said session.
- For that purpose, the method may comprise the following steps between the step of setting the basic pair of operating parameters and the step of deriving the
user 100 oxygen consumption value: -
-
user 100 performance of the exercise in a standard mode according to the basic pair of values set; - presentation to the user of an energy saving mode which involves lower energy consumption by the
motor 5 compared with the basic combination; -
user 100 selection of the energy saving mode.
-
- Advantageously, that allows the user to arbitrarily decide when to perform the exercise in energy saving mode.
- Moreover, the method according to this invention comprises the possibility of varying the operating parameters continuously during the session.
- In particular, the method comprises a step of displaying during the exercise the values relating to a plurality of parameters, including the
user 100 walking or running speed (orbelt 3 movement speed), theexercise platform 3 a incline, themotor 5 energy saving and theuser 100 oxygen consumption. - During the exercise, the
