Quadriceps Concentric vs Eccentric

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.

Primary outcomes

  1. Change in muscle thickness

    Time frame: Before training and after 8 weeks of training

    Change in muscle thickness will be measured by using Ultrasound

Secondary outcomes

  1. Change in muscle strength

    Time frame: Before training and after 8 weeks of training

    Change in muscle strength will be assessed by using hand-held dynamometer.

  2. Change in balance

    Time frame: Before training and after 8 weeks of training

    Change in balance will be measured by using Biodex Balance System.

  3. Change in function

    Time frame: Before training and after 8 weeks of training

    Change in function will be measured by using single leg hop test
