Research on Energy Cost of Human Body Exercise at Different Running Speed

The study of human energy cost during exercise has certain scientific significance and application value in the research fields of human motion biomechanics, sports science and rehabilitation medicine. In order to establish a research method of human energy consumption based on the energy method, a simplified model of the twelve rigid human body in the sagittal plane was established according to the physiological structure characteristics; On this basis, a biomechanical model of human motion based on the body acceleration integral algorithm is established, and a method of human motion energy detection and research based on 12 accelerometers is proposed. For experimental verification, a human body motion energy consumption detection system based on MEMS accelerometer was developed to measure human energy loss at different running speeds. The experimental results show that as the running speed increases, the alternate support period of the left and right feet becomes shorter and the amplitude increases. Therefore, the energy consumption of human exercise will change with the change of running speed. This conclusion provides a reference for the research on energy consumption of human exercise and sports health management.
