Gymnasts are required to complete a series of highly difficult routines that need excellent physical condition and plenty of training time, the post-exercise recovery is crucial. Electromagnetic Treated Water (ETW) is very small water molecule clusters caused by the electromagnetic field which can benefit human body in different ways. Infrared radiation (IR) is commonly used in the recovery period of training. PURPOSE: The aim of the study is to assess the effect of ETW combined with IR on post-exercise recovery. METHODS: Twenty gymnasts from China men's national gymnastics team were randomized to the experimental group (EG, N=10) or the control group (CG, N=10). The CG continued with their daily training, the EG received 3-dimensional IR in a specific cabin for 30 minutes after training and drank no less than 1500 mL ETW per day for 12 weeks. Both groups followed the same training plan, diet and nutritional supplements. Blood parameters, including Routine Blood Test (RBT), Creatine Kinase(CK), Blood Urea Nitrogen(BUN), Dopamine(DA), Serotonin(5-HT) and Blood Lactate Acid(BLA), were detected before(t1), after(t2) and 1 hour later(t3) of training at D1, D42 and D84. In addition, Athlete Burnout Questionnaire (ABQ) and Pittsburgh Sleep Quality Index (PSQI) were collected. RESULTS: Comparing with CG, BLA(t3) and 5-HT(t3) was significantly decreased at D1(0.73±0.26 vs. 1.21±0.34 mmol/L, 160.36±26.96 vs. 189.27±40.24 ng/mL, p<0.01, respectively), BUN(t1) was lower at D84 (4.22±0.98 vs. 5.88±1.07mmol/L, p<0.01), as were Physical/Emotional Exhaustion( 9.4±2.80 vs. 13.0±2.49, P<0.01) and Sport Devaluation (9.3±2.75 vs. 12.1±2.02, p<0.05). PSQI was significantly improved at D42 (5.0±1.33 vs. 6.9±2.38, p<0.05) and D84 (3.5±1.65 vs. 6.6±2.55, p<0.01). BLA(t3) were significantly decreased compared with BLA(t2) in EG at D1, D42, D84 (0.73±0.26 vs. 2.50±0.83, 2.40±1.26 vs. 8.21±5.09, 2.05±0.63 vs. 3.46±1.33 mmol/L, p<0.01, respectively). CONCLUSION: The result of the present prospective study confirmed that ETW combined with IR can eliminate the BLA efficiently, reduce fatigue accumulation, improve sleep quality and decrease athlete burnout, that all can promote the post-exercise recovery.
