Understanding Maximal Tetanic Tension: Definition & Measurement

Maximal tetanic tension is the highest force that a muscle can generate when it is stimulated with a maximal electrical stimulus. It is measured in Newtons (N) or grams-force (gf).

Maximal tetanic tension is determined by the number of motor units that are recruited and the frequency of stimulation. As the frequency of stimulation increases, more motor units are recruited and the force of contraction increases. However, at very high frequencies, the muscle may fatigue and the force of contraction may decrease.

Maximal tetanic tension is an important measure of muscle function. It can be used to assess the strength of a muscle, to diagnose muscle diseases, and to monitor the effects of exercise training.
