Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to see how different forms of the squat exercise change my body's leg muscle activity. Four forms of the traditional back squat will be used: traditional back squat, barefoot squat, box squat, and traditional back squat with chains.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Resistance exercise has various benefits that promote health and reduce the chance of chronic disease, but the biggest benefit may be found in the effects on maintaining muscle mass throughout the aging process. The implications resistance training has on an individual's ability to function throughout the day with less fatigue whilst performing tasks at an easier level can all be related to improved strength and endurance that comes with resistance training. Furthermore, how the nervous system adapts and sends signals to the working muscles are of great interest as neuromuscular adaptations help in coordination, balance, and agility. Variations of the same style of exercise have been theorized to improve and/or change the adaptations that can occur. Thus, the purpose of this study would be to assess surface electromyography (sEMG) activations on 4 anatomical sites simultaneously during the squat exercise under varying conditions.
