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

Outcomes
Primary Outcomes
Surface EMG Measurement
Time Frame: in an average of one hour
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.
Normalization of Surface EMG
Time Frame: in an average of one hour
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.
Secondary Outcomes
