Relationships of the surface electromyogram to the force, length, velocity, and contraction rate of the cineplastic human biceps.

A series of experiments was performed to measure the relationships between the integrated surface EMG and the mechanical state of the cineplastic biceps muscle of one subject. The muscle was studied during static and dynamic isometric contractions at different muscle lengths and during constant velocity isotonic contractions at different loads. The cineplastic biceps results are compared with results obtained from the intact biceps.
