Quadriceps Recruitment And Twitch Properties In Lean And Obese Women Before And After Fatiguing Exercise, Rebekah Seay Carpenter Jan 2021

Quadriceps Recruitment And Twitch Properties In Lean And Obese Women Before And After Fatiguing Exercise, Rebekah Seay Carpenter

Theses and Dissertations--Kinesiology and Health Promotion

Skeletal muscle strength, specifically that of the anti-gravitational muscles such as the quadriceps, is essential for performing dynamic tasks including walking, navigating stairs, and transitioning between sitting and standing. Obesity has been shown to negatively impact musculoskeletal function and decrease quadriceps strength relative to body weight. Additionally, obesity has been linked with higher rates of fatigue and lower strength outcomes following a test of muscular endurance of the quadriceps. Since obesity lowers relative strength, it is likely that quadriceps muscle weakness contributes to reduced physical function of dynamic tasks. However, to date, the precise mechanism for obesity-induced muscle weakness has …
