METHOD AND A SYSTEM FOR ESTIMATION OF A USEFUL EFFORT PROVIDED BY AN INDIVIDUAL DURING A PHYSICAL ACTIVITY CONSISTING IN EXECUTING AN ALTERNATING PEDALLING MOVEMENT ON A PEDAL DEVICE
The method involves a step of measurement of a bearing force (Fp.sub.n) on a pedal (1) of the pedal set (4), different from the useful effort, exerted by the individual during a pedalling cycle, a step of determination of a maximum (max(Fp.sub.n)) of the bearing force measured during the pedalling cycle (CF.sub.j), and a step of estimation of a mean useful effort exerted by the individual during said pedalling cycle from the maximum of the bearing force determined and with the aid of a predetermined correlation function between a maximum bearing force during a pedalling cycle and a mean useful effort in said cycle.
Dynamometer For Use With Rail Equipment, And Systems And Methods Of Using Same
A dynamometer can be used with rail equipment having two pairs of drive wheels. The dynamometer can comprise first and second wheel engagement assemblies, each comprising a frame, a first pair of dynamometer wheels that are spaced relative to a first horizontal dimension, and a second pair of dynamometer wheels that are spaced relative to the first horizontal dimension. The first and second pairs of dynamometer wheels can be spaced relative to a second horizontal dimension. The first pair of dynamometer wheels and second pair of dynamometer wheels can cooperate to define opposing wheel engagement receptacles. A hydraulic motor can couple to the first plurality of support wheels and can be configured to receive a power and an associated torque from a respective pair of the drive wheels of the rail equipment. The first and second wheel engagement assemblies can be movable relative to each other along the second dimension.
Method and a system for estimation of a useful effort provided by an individual during a physical activity consisting in executing an alternating pedalling movement on a pedal device
The method involves a step of measurement of a bearing force (Fp.sub.n) on a pedal (1) of the pedal set (4), different from the useful effort, exerted by the individual during a pedalling cycle, a step of determination of a maximum (max(Fp.sub.n)) of the bearing force measured during the pedalling cycle (CP.sub.j), and a step of estimation of a mean useful effort exerted by the individual during said pedalling cycle from the maximum of the bearing force determined and with the aid of a predetermined correlation function between a maximum bearing force during a pedalling cycle and a mean useful effort in said cycle.
