Abstract

This paper analyzes the effect of obesity on the knee joints during squats. This was performed on 2 different subjects by having each squat 30 times at their decided comfortable depth to display some fatigue and effects on the knee joints. Using the VICON NEXUS and AMTI force plates equipment at The University of Texas at Rio Grande Valley Biomechanics Lab, the center of pressure, knee flexion angles, velocity, and ground reaction forces were calculated. The subjects performed the exercises with and without additional weight using a body vest and kettlebell. The ground reaction forces showed a significant increase in each subject with the additional weight. This plays a tremendous role in musculoskeletal pathology. It was also shown that as the weight was added, the knee flexion angle increases. Phase plane of the knee flexion angle, center of mass of the femur and tibia, center of pressure, and floquet theory were all used to display how the stability is affected when walking and squatting with additional weight.
