Quadriceps Concentric vs Eccentric

July 1, 2020 updated by: Emrullah ALKAN, Dokuz Eylul University

Effect of Different Izotonic Quadriceps Exercise Training on Muscle Strength, Muscle Thickness and Balance in Healthy Individuals

The aim of the study is to compare the effects of concentric and eccentric exercises on muscle strength, muscle thickness and balance in healthy Individuals. Participants will randomly be divided into 2 groups: Concentric exercise (CE) group, eccentric exercise (EE) group. Concentric exercise group will be doing 2 concentric exercises and eccentric exercise group will be doing 2 eccentric exercise for 8 weeks. The evaluations will be repeated after 8 weeks of training to reveal the effects of concentric and eccentric exercises.
