Electromyography (EMG) and Human Locomotion

This paper is focused on the development of musculoskeletal model of the human lower extremity and kinematic and kinetic analysis of the Knee and Ankle during soccer ball kicking. This research study involves Surface Marker and EMG techniques to investigate the kinetics and kinematics of Knee and Ankle in the course of peak performance of a soccer player during kicking action. The musculoskeletal model is developed by means of Surface marker techniques and the related kinetics and kinematics analysis are performed. The EMG Techniques are used to estimate the muscle strength responsible for the Knee and Ankle movement during kicking action. Five soccer players (aged 23 to 25, BMI: 25-29) are involved in the experimental studies. A mathematical model was proposed to convert the EMG signal of muscles into muscle strength through correlation with various models and players. The peak performance of the Knee and Ankle are evaluated in terms of the estimated torque and compared against the measured data.
