Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Concentric exercises; Other: Eccentric exercises

• Registration Number: NCT03636854
• Lead Sponsor: Dokuz Eylul University

Brief Summary

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.
