Weight-lifting exercise machine

摘要

A weight-lifting exercise machine enables an athlete to lift a mass from an initial resting position. After the athlete releases the mass, the machine cushions the fall of the mass, such that the mass returns to its resting position without assistance from the athlete. The movements of the athlete and the mass can be tracked, preferably by wireless accelerometers attached respectively to the athlete and the mass, and data on such movements can be stored and analyzed. The machine provides a monitor to enable the athlete to track the progress of the exercise, and to determine whether the exercise is being performed correctly.

主权项

1. A method of monitoring and analyzing performance of an athlete, comprising:
a) providing an exercise machine in which an athlete repeatedly exerts force so as to lift a mass, wherein the machine includes damping means for cushioning a fall of the mass to a starting position, b) obtaining position data from a first sensor representative of movement of the athlete, c) obtaining position data from a second sensor attached to the mass, and d) analyzing data from said first and second sensors so as to evaluate performance of the athlete, further comprising using data from said sensors to derive graphs representing a velocity of the mass (Vmass) and a velocity of the athlete (Vcore), determining whether such graphs include a condition indicative of incorrect performance of an exercise, and signalling presence of such condition to the athlete.
