Clinical Trial Summary

The aim of this study is to investigate muscular activations during various quadriceps exercises commonly used in clinical settings.


Description:

The quadriceps muscle is known to be crucial for the dynamic control of the lower extremity, and weakness in this muscle can lead to strategies that may result in injury. Therefore, acquiring optimal quadriceps muscle strength is essential not only for preventing lower extremity injuries but also for enabling individuals to fully return to activities after an injury. Despite the existence of various eccentric quadriceps exercises in the literature, there is a lack of consensus on their comparative effectiveness. Hence, there is a requirement for research to explore the effectiveness of different eccentric quadriceps exercises. The objective of this study is to compare the muscular activation of the quadriceps muscle during four distinct eccentric quadriceps exercises using surface electromyography (sEMG) devices

Intervention

Diagnostic Test:
Eccentric quadriceps exercises
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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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
Primary 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. in an average of one hour
