Definitions

  • the present application relates to a device for measuring muscular work and power performed in moving loads associated with a gymnastic apparatus or on so-called body building machines which use gravity-based loading systems.
  • the muscular work and power developed during exercise currently cannot be measured qualitatively, in that when a load is lifted the user who performs the movement can only find out the amount of the load, and therefore of the weight, he has lifted.
  • the user who is training or rehabilitating on the body building machine or on the gymnastic apparatus thus does not know exactly the type and therefore the quality of the muscular work he is performing.
  • the various training plans are in fact planned and expressed as percentages of the maximum capabilities of the user involved.
  • the biological effects which are caused are completely different from those produced in the first case; in the first case it is in fact possible to obtain an improvement in the neuromuscular qualities, whereas in the second case local metabolic processes (i.e. muscular resistance) will be more stimulated.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a device which allows to provide the user of body building machines or of gymnastic apparatuses data and recordings related to the type and quality of the muscular work performed and therefore to the physiological effects caused by the training.
  • Another important object is to provide a device which also allows to display and record the biochemical energy used to produce the mechanical work.
  • Still another important object is to provide a device which associates with the preceding characteristics that of indicating and recording data which allow to identify the metabolic processes in their various forms.
  • Another important object is to provide a device which associates with the preceding characteristics that of displaying and recording the amount of energy consumed to produce concentric muscular work and eccentric muscular work.
  • Still another important object is to provide a device which is structurally simple as well as easy and rapid to apply to body building machines or gymnastic apparatuses.
  • Another important object is to provide a device which associates with the preceding characteristics that of being reliable and safe in use, without requiring particular technical conditions for its use.
  • Not least object is to obtain a device which has modest costs and is not subjected to frequent maintenance.
  • a device for measuring muscular work and power performed in moving loads associated with a gymnastic apparatus or with a body building machine characterized in that it is constituted by one or more means, associated with said body building machine or rigid apparatus, which are suitable for measuring the movement of said loads and the time used to achieve said movement, said means being connected to a device for displaying data such as the muscular power developed during the exercise and the amount of biochemical energy used.
  • the reference numeral 1 indicates a body building machine or a gymnastic apparatus which, in the particular indicated case, is constituted by a framework 2 which has adapted lateral supports 3 for guiding a bar 4 with which loads, constituted by conventional disks 5, can be associated at the ends.
  • the device for measuring muscular work performed by the body building machine 1 comprises means for measuring the movement of the gravitational load constituted by the bar 4 and disks 5; said means can be constituted by photoelectric cells, infrared-ray devices, accelerometers, optical-fiber systems or in any case known sensing systems which, in the particular embodiment, are indicated by a detector (encoder) 6 which is supported on the framework 2 by means of a first bracket 7 and has a shaft 8 keyed at a first pulley 9 which is rotatably associated with a second bracket 10 rigidly associated with the framework 2.
  • a tension element such as a cable or a sheath 11, is associated at the first pulley 9 and interacts with a second pulley 12 which is rotatably associated at a third bracket 13 which is rigidly associated with the framework 2.
  • first pulley 9 is associated proximate to the lower end of the framework 2
  • second pulley 12 is associated at the upper end of said framework.
  • the cable or sheath 11 is furthermore connected at the bar 4 so that a vertical movement thereof corresponds to an analogous and equal movement of the cable or sheath 11, this movement being detectable by means of the detector 6.
  • the device for measuring muscular work furthermore comprises means for displaying and storing the movement imparted to the bar 4; said means are constituted by a unit 14 which is connected to the detector 6, has a display 15 and is internally provided with a central processing unit for the processing of the information from said detector 6.
  • Said unit 14 therefore allows to also measure the time used by the user to achieve the movement imparted to the gravitational load and to process this datum together with the datum related to the movement.
  • a computer 16 can be connected to the unit 14 to handle and process the data detected and processed at the unit 14.
  • the unit 14 measures, by means of the detector 6, the movement of said load and simultaneously measures the time required to perform this movement.
  • a central processing unit such as a microprocessor, once it has received the information on the movement and the time required to move the load, calculates the amount of work and of average developed power.
  • the work of the average power can furthermore be expressed as a percentage of the maximum work of mechanical power performed by the muscles involved in the movement.
  • biochemical energy The energy used by the muscles and which derives from distinct metabolic substrates is termed hereinafter “biochemical energy”: the amount of said biochemical energy used during muscular contraction can be calculated by considering both the energy used during concentric (positive) work, which is indicated by Lpos, and the biochemical energy used during eccentric (negative) work, which is indicated by Lneg.
  • Eln Lneg x B , where the coefficient B can assume values comprised between a minimum of 0.60 and a maximum of 2.00.
  • the device can also evaluate the maximum power which a given muscle or group of muscles can develop.
  • Said maximum power can be indicated as 100% x 100% of maximum power.
  • the device calculates the value as a percentage of the maximum power.
  • the person can receive a visual or acoustic item of information which informs him concerning the amount or quality of the muscular work produced, and is therefore automatically informed concerning the type of biochemical energy which he is using during contraction.
  • the materials and the components of the device may also naturally be the most appropriate according to the specific requirements or to the particular body building machine used.
