The regulation of competitive form depends upon accurate measurement. In practice, we cannot now do much. T'he skill events require athletes to possess rapid, sensitive and exact perceptions and nervous system to control their muscles. Thus, the competitive form of a skill event depends upon brain functions. However, the continuous high pressure, large quantity of training and competitive stress result in central fatigue, which leads to a decline in brain function.
Central fatigue is also a cause anxiety and other mental barriers.
Recently, more and more attention has been devoted to central fatigue of professional players. The researchers involved in this study thought that central fatigue can result in other problems. The decline of the athlete' s brain function is caused by central fatigue. To some extent, brain waves can reflect central fatigue and brain function, so brain wave measurements can be used to evaluate the competitive form of skill event athletes. A total of 14 athletes, among them 12 clay shooters and 2 high jumpers, aged 18-30, were all national level players.
