Abstract
The aim of this study was to compare the electromyographic (EMG) activity and maximum isometric voluntary muscle contraction between rectus and biceps femoris muscles for kick and support leg in soccer players. The performance of (11) of Saudi soccer players was examined, the authors collected data by measuring EMG using DELESYS which is one of the leading companies in manufacturing electrical activity measuring equipment by using two isometric tests for maximum voluntary muscle contraction from sitting and lying position, the main experiment has been conducted on the 4th and 5th of February 2019 in the biomechanics lab located inside the Biomechanics and Motor Behavior department in the faculty of Sport Science and Physical Activity at King Saud University.
The results reveal that the measures of Maximum Isometric Voluntary Contraction (MVC) indicate the need for balancing the intensity of training for all muscles group. A balance in strength between the both kicking and supporting rectus and biceps femoris muscles has been shown to be of utmost importance, this is in turn reflected in the accuracy and effectiveness of skill performance which lowers the risk for injuries as a result of the existing balance between body parts.
