- Abstract:
- To study neuromuscular variables in isometric contraction, a body-fixed ankle dynamometer with integrated electromyographic (EMG) system and software-controlled load tests was developed. It consists of a footplate acting against a load cell in plantar flexion. Counteraction is supported by a perpendicular telescopic stand which runs from the heel to the thigh with the knee flexed at an angle of 90 degrees C. Additional to contraction force, force tremor and surface EMG from the triceps surae and tibialis anterior muscles are recorded. The software consists of three load tests to assess variables of muscle fatigue, motor performance and motor memory. The dynamometer was optimised in relation to functionality and selection of construction materials for the use on the Russian MIR space station.
