Effects of Squats Exercise with EMS on Muscle Strength, Endurance, and Body Function

Abstract

Background/Objectives: The purpose of this experiment is to find out the degree of improvement by clarifying the effects of squats after attaching them to EMS through the functions of the body, such as muscle strength, jumping, and muscle endurance. Methods: The participants were divided into EMS squat group (ESG), squat group (SG), and control group (CoN) without squat exercise, and measured all subjects. Squat exercise was performed at 90° knee flexion with broad legs and straightened waist. Using ultrasonography, we measured the thickness of vastus intermedius (IM), rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), rectus abdominis (RA), external abdominal oblique (EO), internal abdominal oblique (IO), and transverse abdominis (TrA). And we measured jump, height, endurance, and agility. Findings: Squat movement applied with EMS improved jump, endurance, and agility, and increased the thickness of quadriceps muscle except VL, VM, and abdominal muscle, except TrA. However, we found that in endurance, there is not much difference from squat exercise. Improvements: There was a time constraint because the study was conducted for a short period, and the study was limited due to the occurrence of the elimination due to the strength of exercise.
