Many studies have demonstrated an inverse relationship between fatigue and performance of any task, specifically the coordination with which one performs the task is seriously affected. This idea has serious implications regarding anyone who is working towards specific performance based goals i.e. throwing a football or baseball, high jumping, swinging a bat, etc. Coordination is essentially a mental skill that is executed by finely tuned cues from the nervous system. This skill plays a crucial role in any movement because it is an individuals level of coordination that separates an excellent performance from an average performance. Leading us to the conclusion that fatigue hinders performance because fatigue affects coordination directly. This conclusion I see has three implications.

1. Having skill under fatigue is definitely a skill in itself. This being the primary reason for the types of training that are employed by our military branches. Soldiers are pushed to and beyond their fatigue thresholds and forced to perform activities that require high levels of focus and coordination. Placing individuals in such situations leads to the development of the ability to perform under incredible fatigue

2. While learning a new movement or motor skill it is crucial that all factors involving fatigue must be eliminated from the equation. If fatigue can hinder coordination and thus one's performance then fatigue will hinder the way one learns a movement leading to compensations and dysfunction in the particular movement. By eliminating stress and fatigue we insure the movement is learned correctly and safely.

3. If you improve your fitness level fatigue will play a smaller factor in affecting your performance.

While fatigue is necessary to adapt be sure to apply stress and fatigue at the appropriate time and in the appropriate manner. Avoid placing fatigue on yourself whenever taking on a new exercise, movement pattern, or sport rather focus on executing the movement with precision and clarity.
