In sports practice, cold water baths are increasingly used by athletes and practitioners to relieve post-exercise fatigue and accelerate the recovery of physiological functions and athletic ability. Various cold bathing schemes with different water temperature and time combinations used in previous studies can all produce a certain recovery effect, but it is still difficult to determine the appropriate cold bathing scheme that is conducive to short-term recovery. Its relatively good recovery effect is sought under the condition that the time combination is controlled. The purpose of this paper is to investigate the effect of an intervention on the recovery effect of cold water baths after resistance training. The research in this paper will use literature method, experimental method and mathematical statistics method to sort out the existing literature data, and carry out experimental research on the basis of the existing research results. Physiological function and the recovery effect of the ability to exercise again in a short period of time, explore its mechanism, and provide a reference for the practical application of cold water bathing. Experiments have shown that different cold bath programs have different intervention effects after resistance training, which can increase the recovery effect by about 10% and shorten the recovery time.
