Some factors that have been proposed to explain the fall in force duringfatigue include: changes in the 'sense of effort', loss of 'central drive', failure of neuromuscular propagation, reduction in calcium release in excitation- contraction coupling, metabolic changes in the muscle, and reduction in muscle blood flow owing to compression of blood vessels. 1.

You know that cramps are caused by over-active motor nerve activity to the muscle. Your associates want to stretch the cramping hamstring, but you say, “No! I want the player to concentrate on contracting his right quadriceps muscles before we stretch.” Why might stretching a cramping muscle INCREASE the cramping?arrow_forwardDefine the all-or-none principle.
