Muscular Activations During Eccentric Quadriceps Exercises

Not Applicable

Completed

• Conditions: Muscle Weakness; ACL Injury; Sport Injury; Sports Physical Therapy
• Interventions: Diagnostic Test: Eccentric quadriceps exercises

• Registration Number: NCT06162130
• Lead Sponsor: T.C. ORDU ÜNİVERSİTESİ

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

Primary Outcome Measures

Name	Time	Method
Surface EMG Measurement	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	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.
