The aim of this study was that effect of precooling treatment on muscle damage and maiximal muscle power. Ten subjects(age 22.5±1.25 years, Height 176.3±2.23 cm, Weight 72.4±1.23 kg, body fat 23.5±2.56 %, VO<sub>2</sub>max 55.3±2.78 ml/kg/min) performed one 30-min self-paced cycling with three 30 seconds all-out sprints at 10-min intervals with and without lower extremities precooling. Precooling treatment completed two times for 5-min at 10℃ water bath. Peak power output(Watts and Watts/kg) and ratio of fatigue was measured by Wingate test. PSI(physiological stress index) was calculated by rectal temperature and heart rate variables. Blood CK and HSP72 was assayed for evaluating of muscle damage and heat shock.
Precooling treatment would increased rectal temperature and the pick power(p<.05). Also precooling was allowed to attenuate the physiological stress index(PSI). There were significant different at the blood creatine kinase in precooling experimental condition(p<.05).
In conclusion, it is less well documented how precooling enhances intermittent high-intensity exercise of short duration. It is clear that precooling does allow a greater rate of heat storage, but precooling is probably only beneficial for endurance exercise in warm and humidity condition rather than intermittent or short duration exercise. In response to precooling can alternate in peripheral neural activity occurred to prevent local muscle injury. Further investigation in which changes in multiple physiological systems are assessed systematically are required so that the underlying mechanisms related to the development of fatigue during various exercise intensities, and types such as intermittent high-intensity exercise in normal environment condition.
