Objective: To explore the effect of repeated contrast water therapy(CWT)on physiological function of elite badminton players after training. Methods:Sixteen elite badminton players were randomly divided into the CWT group and the CON group , with eight players in each group. According to the two-week strength and conditioning plan, CWT or passive rest was adopted as cooling-down after each training. By dynamically monitoring the subjective fatigue, sports perfomance and metabolic indexes of athletes, the effects of CWT were analyzed. Results:In terms of subjective sensation, the degree of muscle soreness and rating of perceived exertion(RPE) of the CWT group were significantly lower than those of the CON group immediately after weekly training and after weekend rest(P<0.05). After the weekend rest, the muscle soreness and fatigue of both groups of athletes were significantly relieved(P<0.05). In terms of perfomance, the CWT group did significantly better than the CON group in static squat immediately after the weekly training(P<0.05), and the CWT group also did significantly better than the CON group in standing long jump immediately after the two-week training(P<0.05). After weekend rest, there was no significant change in the results of standing long jump and static squat for the CWT group(P>0.05). In terms of metabolic indexes, with two weeks' intense training, there was no significant difference in serum CK concentration between the two groups(P>0.05); while after two weeks of training, the serum BUN concentration of the CWT group was significantly lower than that of the CON group(P<0.05). Conclusions:CWT can relieve the muscle soreness and RPE of badminton players after strenuous exercise, slow down the decline of performance in standing long jump and static squat, and may reduce protein decomposition level in the body. |
