Official title
Evaluating Test-Retest Reliability of Surface Electromyography (sEMG) in Measuring Fatigue in Adolescents Through Prolonged Activity
Overview
This cross-sectional study aims to determine the test-retest reliability of surface electromyography (sEMG) outcomes in detecting levels of fatigue among healthy adolescents engaged in physical activities. It seeks to evaluate the consistency of sEMG parameters across two test sessions and correlate these measurements with both performance metrics and subjective fatigue assessments. Participants will perform repetitive squatting until volitional exhaustion while their muscular activity is recorded. They will do so on two different test sessions with an interval of one week in between.
Interventions
- Diagnostic test Surface Electromyography
The primary lower limb muscles to be monitored include the gluteus medius, rectus femoris, vastus lateralis (quadriceps ), biceps femoris (hamstrings), tibialis anterior, and gastrocnemius medialis (calves). This setup fully utilizes a 16-channel sEMG system by monitoring each muscle group bilaterally to capture comprehensive data on muscle activity and fatigue.
Primary outcome measures
- sEMG median power frequency (MPF) - test [Time frame: first test session at day 1]
- sEMG median power frequency - retest [Time frame: second test session after 1 week]
- sEMG RMS amplitude - test [Time frame: first test session at day 1]
- sEMG RMS amplitude - retest [Time frame: second test session after 1 week]
Secondary outcome measures (2)
- VAS score - test [Time frame: first test session at day 1]
- VAS score - retest [Time frame: second session after 1 week]
