A lifting, monitoring and exercise training system.

摘要

The invention is directed to a microprocessor based system utilizing electromyographic sensor (22) to monitor muscle force for lift training and exercise training. In the lift training embodiment the electrodes (12, 14, 16) of the electromyographic sensor are secured to a belt (10) so that they are lcoated adjacent to the lower back of the user when wearing the belt. The lift training embodiment is also provided with a goniometer (20) to measure lifting angle during training, which together with muscle force generated by the lower back is compared by the microprocessor to preprogrammed lifting parameters and if these parameters are exceeded the user is warned by an audible indicator (27). The lift trainer embodiment also periodically measures interelectrode impedance to insure actual usage. The exercise training embodiment has a bar graph display (50) displaying muscle intensity and two light emitting diodes (52) alerting a user when to contract or relax a monitored muscle group. The microprocessor is preprogrammed with a exercise routine and alerts a user when the routine is to begin, the duration of muscle contraction and relaxation, and the repetitions required. During exercise the user can monitor muscle intensity from the bar graph display (50) and or auditory feedback element (27). An alternative lift training system comprises a belt mounted goniometer (20) which is operatively coupled to a microprocessor having an electronic memory (25) for time logging a lifting session. To insure actual usage the belt is provided with temperature and/or motion sensors.
