About this study
Official title: The Effect of Different Focusing Methods on Muscle Activity During The Single Leg Squat Movement
The aim of this study is to compare the effects of different focusing methods on muscular activity
Read the 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
