Effect of nutritional supplement accompanying functional strength exercises on the special physical abilities and the spiking skill of volleyball players

Abstract

The process of preparing players and developing their level is of great importance, and it is a comprehensive process that goes beyond the reservoirs of sports training in isolation, but rather seeks to strengthen it with supporting elements, including nutritional supplements. In performing advanced skills in volleyball, including the skill of crushing striking, as well as weakness in special physical abilities. The research aims to: prepare a training program for functional strength that fits the capabilities of the research sample, determine doses of nutritional supplements commensurate with the mass of the players, and identify the effect of the training program for functional strength accompanying nutritional supplements on special physical abilities and the performance of the skill of crushing volleyball.The researchers used the experimental method (designed by the two experimental groups), the first experimental group practiced functional strength exercises with doses of nutritional supplements, and the second group practiced functional strength exercises in isolation from nutritional supplements. The research sample was selected from the specialized school volleyball players. The functional strength-training program was implemented; the researchers concluded the success of the functional strength training program in developing the special physical abilities of volleyball players and the development of the skill of crushing hitting, need for (8) weeks, at a rate of (3) units per week, and a rate of (24) training units.
