Analysis of physical activities in wu-shu training.

The present study proposed methods of preventing diseases, controlling chronic degenerative diseases and promoting health, which are major concerns of sports medicine. In the proposed methods, we analyzed wu-shu trainees' physical activities scientifically and quantitatively. The amount of physical activities was measured using SenseWear-PRO2-Armband developed by Body-Medai Company. The armband includes skin temperature sensor, skin surface temperature sensor, accelerometer, thermal diffusion sensor, and galvanic skin reaction sensor. Obtained data were recorded in the armband. Recorded data were analyzed using InnerView Wearer Software in terms of skin temperature, calorie consumption and the amount of physical activities. According to the results, those had continued exercise for a long time consumed a lot of energy in a short time, and intensive physical activities increased energy consumption and, at the same time, raised temperature. In addition, our experiment showed that the increase of energy consumption also raised skin temperature, which in turn caused heat flux. What is more, skin conduction appeared not to be affected by factors such as physical activity, energy consumption and skin temperature. The results of this research may provide information useful for preventing cardiovascular diseases, controlling chronic degenerative diseases and ultimately managing health through activating physiological metabolism.
