The effect of voluntary fatigue on the involuntary muscle activity of selected arm muscles. Supplement abstract 865.
Reflexes are actions that serve to protect and stabilize the human body.
Fatigue is the result of the body exhausting its readily available reserve of fuel that enables the muscle to work. It is not clearly understood how skeletal muscle reflexes are affected when the body reaches a state of fatigue. Ss completed six trials to fatigue. The exercise consisted of holding a 5-pound weight via a rope and handle. Ss had to react to an unannounced 20-cm drop of the weight, which caused rapid elbow extension.
