General Description

The person being measured rests on the measurement table. A special sensor is placed on the muscle we wish to measure – the sensor is designed to register the muscle contraction. The muscle contraction is induced artificially with an electro stimulator. The contraction of the muscle under isometic conditions results in a radial displacement of the sensor rod. This radial displacement is recorded as a function of the elapsed time. The sensor is connected to a computer where a specially designed software plots the radial displacement of the sensor rod against time.

Muscle contraction time is statistically highly correlated with the ratio of fast and slow muscle fibers. Depending on its value, we can classify the measured muscles as slow (tonic) or fast (phasic.)
