دراسة معدل الطاقة المصروفة أثناء الجهد و القدرة الوظيفية الفوسفاجينية القصيرة و علاقتهما بالضربة الهجومية الساحقة لدى لاعبي الكرة الطائرة

Abstract EN

The research included the introduction and the significance of research.

The researcher explained the importance of volleyball, which is one of the collective games that has its basic principles and its different skill and the association of this game closely related to physiology.

The functional efficiency possessed by the athlete has a direct role and the large and influential in the level of performance in the right manner, which results in good performance to win the game and also the research contained .

The research problem is that most of the trainers focused on the skill performance and didn’t pay special attention to the functional variables, including the rate of energy spent during the voltage and the short phosphophonic capacity, which has a direct impact on the accuracy of the outstanding performance.

Therefore, the researcher decided to study this problem by conducting a study showing the relationship of the rate of energy spent during the effort and the short physiognomic ability, .

The study included research methodology, field procedures, a description of the society and sample of the research.

The number of players who were tested was 9 players representing the university's volleyball team in the Faculty of Physical Education and Sports Sciences.

The percentage of the sample was 75% and the research variables and most important tests used as well as statistical methods were identified
