The Effect of Different Focusing Methods on Muscle Activity

Completed

• Conditions: Knee Injuries and Disorders
• Interventions: Other: Single leg squat

• Registration Number: NCT05185882
• Lead Sponsor: Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey

Brief Summary

The aim of this study is to compare the effects of different focusing methods on muscular activity

Detailed Description

After the first data collecting ( Demographic data, Inclusion criteria) surface electromyography EMG evaluations will be taken from 6 muscles( Vastus Medialis, Rectus Femoris, Vastus Lateralis, Biceps Femoris, Semitendinosus, Gluteus Medius). These recordings will be taken in 3 different circumstances: 1- Without a focusing method 2- With an external focus and 3- With an internal focus
