【摘要】：目的:觀察擇時(shí)運(yùn)動(dòng)對(duì)青年男子運(yùn)動(dòng)員組織損傷和氧化應(yīng)激的影響,為科學(xué)指導(dǎo)訓(xùn)練提供理論依據(jù).方法:25名青年男子足球運(yùn)動(dòng)員進(jìn)行兩次Wingate實(shí)驗(yàn)(兩次測(cè)試的間隔為3d),測(cè)試時(shí)間分別在清晨(7:00~9:00)和傍晚(17:00~19:00).測(cè)定受試者口腔溫度并取靜脈血測(cè)定,測(cè)定血常規(guī)、血生化、組織損傷和氧化應(yīng)激標(biāo)志物.結(jié)果:1)受試者最大功率、平均功率和疲勞指數(shù)以及RPE值在傍晚高于清晨(P0.05);2)安靜時(shí)(運(yùn)動(dòng)前),傍晚口腔溫度、WBC及其亞群、血生化(GLC和CRE)、組織損傷標(biāo)志物(CK,LDH,AST和ALT)和氧化水平(MDA)高于清晨(P0.05),RBC,HCT和抗氧化水平(T-AOC,TBIL和UA)低于清晨(P0.05);3)清晨運(yùn)動(dòng)后除抗氧化參數(shù)外均顯著性升高(P0.05),傍晚運(yùn)動(dòng)后所有指標(biāo)均顯著性增加(P0.05);(4)傍晚運(yùn)動(dòng)后除抗氧化參數(shù)和HCT外其他各指標(biāo)均高于清晨運(yùn)動(dòng)后水平(P0.05).結(jié)論:1)青年男子足球運(yùn)動(dòng)員的無氧運(yùn)動(dòng)能力和運(yùn)動(dòng)性疲勞程度在傍晚高于清晨,其原因可能與安靜狀態(tài)下組織損傷和氧化應(yīng)激水平具有日節(jié)律波動(dòng)性有關(guān);2)一次高強(qiáng)度運(yùn)動(dòng)后組織損傷與氧化水平的日節(jié)律變異依然存在,而抗氧化水平的日節(jié)律變異則減弱.
[Abstract]:Objective: to observe the effects of timing exercise on tissue injury and oxidative stress in young male athletes, and to provide theoretical basis for scientific training.Methods two Wingate experiments were conducted among 25 young male soccer players (the interval between the two tests was 3 days, the test time was 7: 00 in the morning, 9: 00 in the morning) and the evening was 17: 00 to 19: 00 in the evening.The oral temperature and venous blood were measured, blood routine, blood biochemistry, tissue injury and oxidative stress markers were measured.Results the maximum power, average power, fatigue index and RPE value of the subjects were higher in the evening than those in the early morning (P 0.05).GLC and creatinine, tissue damage markers (CK LDHN AST and alt) and oxidation level (MDAs) were higher than those in early morning (P0.05), and the levels of anti-oxidation (TAOCTTBIL and UAA) were lower than those in early morning exercise (P 0.05). After exercise in the early morning, all indexes were significantly higher than those in early morning exercise except antioxidant parameters. All the indexes were all increased after evening exercise.There was a significant increase in the indexes except antioxidant parameters and HCT after exercise in the evening, which was higher than that in the early morning exercise level (P 0.05).Conclusion: (1) the degree of anaerobic exercise ability and exercise fatigue of young male football players was higher in the evening than in the early morning.The reason may be related to the daily rhythmic variability of tissue injury and oxidative stress level in quiet state. (2) the daily rhythmic variation of tissue injury and oxidation level still exists after a high intensity exercise, but the daily rhythm variation of antioxidant level is weakened.
