Role of Body Weight in Biomechanics of Obesity

Obesity alters muscle recruitment and joint kinematics during gait. 

However, it is unclear whether these changes are due to excess body weight itself or differences in limb volume.

Dr. Lance Bollinger, a faculty member in the UK College of Education’s Department of Kinesiology and Health Promotion, is currently using wireless electromyography, inertial measurement units, and electrogoniometers to examine muscle activity and joint kinematics of obese women walking on a positive-pressure treadmill.

By increasing air pressure about the lower body to counteract the effects of gravity, his research team is studying the effects of weight loss without affecting limb volume while walking.

This innovative methodology will help reveal the role of body weight on muscle recruitment and joint kinematics in obesity.
