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

Conditions

• ACL Injury
• Sport Injury
• Sports Physical Therapy
• Muscle Weakness

Interventions

Type	Name	Description
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.
