Outcome Measures

Primary Outcomes (2)

Surface EMG Measurement
During data collection, the EMG Noraxon MiniDTS system (Noraxon Inc.) was used to measure the signals from the muscle. Additionally, the participants were video-recorded to prevent any potential mistakes that might have gone unnoticed during the activities.
in an average of one hour
Normalization of Surface EMG
To normalize the EMG data obtained during the exercises, MVIC will be performed for each muscle using an isokinetic dynamometer. Participants will be shown a video demonstrating the movement for MVIC, and before the test, they will be asked to warm up for 5 minutes on a treadmill at submaximal speed and then perform the movement. To ensure electromyography (EMG) normalization, participants will be asked to perform 3 repetitions, and the average of these three values will be taken.

Diagnostic Test: Eccentric quadriceps exercises

Interventions

Eccentric quadriceps exercisesDiagnostic test

The activation of the vastus medialis, vastus lateralis, and rectus femoris muscles will be measured using surface electromyography (sEMG) during four distinct quadriceps eccentric exercises: Reverse Nordic, Pistol squat, Suspension-based Bulgarian split squat, and Bulgarian split squat. Participants will be instructed to perform three successful repetitions for each exercise. A 30-second break will be provided between each repetition, and there will be a minimum of 10 minutes of rest between each of the four exercises. Due to the belief that fatigue could impact exercise performance, the modified Borg scale will be used to ensure that fatigue does not occur before each exercise. Exercise recording will commence when scores reported using the modified Borg scale are 1 or lower.
