Comparative Analysis of the Biomechanics of Sit-tostand Movement in Normal and Obese Teenagers
The purpose of this paper is to present a comparative analysis of the biomechanics of sit-to-stand (STS) movement in normal and obese teenagers based on measurement data. First, ten volunteers were enrolled as normal group and the other ten volunteers were enrolled as obese group. A measurement system was set up with an infrared camera subsystem and a force measurement subsystem. Then, the participants were asked to act STS movement and the measurement data were recorded and processed, which included trunk flexion, ankle dorsiflexion and knee extension moment. At last, the data were analyzed and the results showed obvious differences in the biomechanics of STS movement between normal and obese teenagers. The kinematics difference is that the obese teenagers have higher trunk flexion and greater ankle dorsiflexion, while the kinetic difference is that the obese teenagers need higher knee extension moment. The result could be of useful for obese teenagers to lose weight.
