Guys, thanks for the replies, starting to get my head around this now!!
Have been looking at the CNS stress in training programs, and am unsure on the specifics. Are we talking CNS fatigue due to suboptimal descending drive and changes in afferent inputs, or more towards the peripheral sites such as an impairment at the NMJ where the action potential fails to cross the motor neuron to the muscle fibre?? Or is it both??
Thanks guys
