Research On The Effects Of HiHiLo On Physical Ability Of Elite Wushu Sanda Athletes

Research objective:Through making analysis on physical ability and correlative indexes of Seven elite Wushu Sanda athletes before and after HiHilo training for 3 weeks,observing the changing pattern and discussing the effects of HiHiLo on physical ability of elite Wushu Sanda athletes,the popurse is to provide theoretical and practical basis for Wushu Sanda Event in using this method.Research metheds:Seven male elite Wushu Sanda athletes were trained by three weeks HiHiLo,which were exposed to the room of simulating 2000m～2500m elevation(14.7%-15.4%O2) everynight for more than 10h, trained in the hypoxic environment of simulating 2500m elevation(about 15.4%O2) three times every week,and had normal life and conventional training of Wushu Sanda at sea level other times in everyday.Through experts consultation,ditermined monitor indexes,and then,physical ability,VO2max,BLA and SpO2 were tested before and after HiHiLo,and testing blood in the morning,separately in the last day before training, everyweek during HiHiLo and in the 3rd day after HiHiLo.Record and statistic the results,then compare and analyze them,research the effects of HiHiLo on elite Wushu Sanda athletes' physical ability more comprehensively.Research results:(1)After HiHiLo,the result(time) of synthesis physical quality and the average results(time) of every turn-back runs are better than before obviously(P<0.01),at the same time,heart function and the subjective feeling of physical strength have been improved.(2)After HiHiLo,absolute value and relative value of VO2max increased significantly(P<0.05) than before,the maximum work rate of achieving VO2max also increased significantly(P<0.01),and the time that strength used up also lengthened obviously(P<0.01).(3)Before and after HiHiLo,two curves of BLA-W have the same tendency,but the BLA in the same shoulder become lower,the AT,aerobic exercise ability has been strengthened.(4)Before and after HiHiLo,SP02 increased obviously not only before excersise,but also during excersise and after excersise. (5)Before and after HiHiLo,RBC,Hct and HB appeared non-significance, the body function is in good condition.In addition,HiHiLo can develop the level of direct correlative blood indexes of organism oxygen transportation ability of Wushu Sanda athletes,this change mainly appeared in the 2nd week.Research conclusion:HiHiLo can enhance physical ability of Wushu Sanda athletes,increase organism aerobic ability,and the body function is in good condition.Moreover,athletes' blood indexes are in the high level of the normal range,it explains that athletes' circulatory system is good,and is at good condition.
