The effect of special exercises according to predicting the limits of the sporting peak on some physical abilities and physiological variables and achieving an Event 400-meter

Abstract

The research aimed to prepare special exercises to predict the limits of the sporting peak for the 400-meter running event. As for the research methodology, the researchers used the experimental method and the method of the two equal groups, experimental and control, for its suitability and the nature of the research problem. The research population consisted of 400-meter runners who actually participated in the Iraqi club championship, and they numbered (10) runners. As for the research sample, it was chosen by systematic randomness and constituted a percentage of (100).  %) of the original community. The sample was divided into two groups, each group containing (5) contestants. The two exploratory and main experiments were conducted and appropriate means were adopted through which the research objectives were achieved. The researchers concluded that special exercises had an impact on the development of the players’ level.  As well as the possibility purpose.  The study recommended taking advantage of the peak limits to identify weaknesses in the competitor’s level and before an appropriate period of time during which the coach can modify the exercises .
