II. Real life problem. You are a trainer and are called on to the field where a player is down with a severe cramp of his right hamstring (biceps femoris) muscle. 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?

Muscle physiology: You are in the gym and doing strength training. You feel in good shape and should try to break personal records in squats. You place the bar on your back and start to take in, ie. your motor neurons begin to send action potentials through all your motor units to the thigh muscles. Task 1: Describe how these action potentials lead to your muscles contracting. The description must follow the correct sequence order and you must explain what happens and why. Task 2: What is the contraction called when you a) bend down and b) are in good shape and can generate more force than what the bar weighs c) stay standing in a and the same position without being able to push yourself up while standing?
