Brief summary

The aim of this study is to compare the effects of different arm positions on muscle activity during single leg squat.

Detailed description

The aim of our study is to examine the effect of different positions of the arms on lower extremity muscle activations during Single Leg Squat (SLS). This prospective cross sectional study included single leg squat test assessments in different arm positions: 1) Arms free, 2) Arms flexed 90 degrees, 3) Hands on hip, 4) Arms across the chest. Inclusion criteria were being a young adult (20-30 years old), physical activity level of at least 4 on the Tegner Activity Scale, and volunteering to participate in the study. Those with a history of lower extremity injury in the last 1 year will be excluded from the study. Our study will contribute to distinguishing SLS variations for clinicians and researchers and choosing the appropriate SLS for evaluation and treatment.

Interventions

OTHERSingle Leg Squat

After initial data collection (Demographic data, Inclusion criteria), surface electromyography EMG assessments will be obtained from 1 muscle ( Vastus Medialis). EMG evaluation will be done in different arm positions during the single leg squat. These records will be taken in 4 different situations: 1) Arms free, 2) Arms flexed to 90 degrees, 3) Hands on hips, 4) Arms across the chest.
