Comparison of Lower Limb Muscles Electromyography Activity Between Vertical and Long Jumps as a Certified Test of Muscle Power in Athletes

Abstract

The aims of this study were to compare the difference of the EMG signal for the lower limbs Between Vertical and Long Jumps as a Certified Test of Muscle Power in Athletes. The performance of 14 Saudi elite athletes in different sports, the authors collected data by measuring EMG using DELESYS, one of the leading products in electrical activity measuring equipment by conducting vertical and long jump test, the main experiment was conducted on November 2019 in the biomechanics lab located inside the Biomechanics and Motor Behavior Department of the College of Sport Sciences and Physical Activity at King Saud University. The results of this study included that femoral muscles contributed most during the long jump test, tibial muscles contributed most during the vertical jump test, all muscles except for the anterior tibial muscle had high contribution rates in the long and vertical jump tests.
