83] experimentally determined the interrelationships among oxygen supply, motor unit activity, and blood lactate during intermittent isometric contractions of the hand grip muscles. Subjects performed for 2 seconds 20% of MVC followed by 2 seconds of rest repeated for 4 minutes under free circulation and/or arterial occlusion between the first and second minutes. The constancy of both intramuscular motor unit spikes and surface EMG activity during isometric contraction indicated no electrophysiological signs of muscular fatigue with free circulation condition.

For the EMG signal, the K+, the Na+, and the Cl- channels in the sarcolemma (and in the T-system, as a second approximation) are essential. Force production is dominated by channels through which Ca++ ions are released. Electric membrane properties were already studied in detail around the mid-twentieth century with voltage clamp techniques. The understanding of individual membrane ion channels is an important challenge for modern cell biology and electrophysiology [2], for which the so-called patch clamp techniques were a crucial development [96].
