Relationship ability and explosiveness electrical upgrading some of the muscles of the leg beating the Spiking skill accurately with young players in volleyball

Abstract

The study aimed to identify the amount of explosive power and indicators of electrical some muscle leg upgrade (summit and time to recruit motor units) to perform the skill of the Spiking skill and determine the relationship between them.the researcher used descriptive approach to solve the problem manner relations correlation and sample consisted of (13) for the player of the club (Karkh and al senaa) was measured indicators of electrical muscle using a device (EMG) Bluetooth and variable explosive power by the (foot scan) as well as the measurement accuracy the Spiking skill and the most important conclusions - coordination happening between the work of the muscles of a leg raising helped to increasethe explosive power and led to the emergence of the result Direct Proportion with accuracy the Spiking skill. there is some variation in the electric leg muscles improve as the highest peak appeared in the Tibialis anterior muscle and less summit in Sartorius muscle and there is some correlation between electrical muscle man working for improving the accuracy and performance of the Spiking skill.
