Abstract:
Objective To establish the regression equation for the maximum oxygen uptake(VO2max)of male young endurance athletes at altitudeby modeling relevant indicators.Methods A total of 81 young male endurance athletes(long-distance runner,marathoner,and race walker)aged 15～18 years old were selected as the research subjects.The VO2max,3000-meter timed run,400-meter timed run,body morphology,body composition,hematological indicators,and cardiac function of the ath-letes were tested in Kunming,Yunnan Province(1890 meters altitude high)in four consecutive days.The testing sequence of the exercise was randomly arranged.The data of the first 65 athletes were used for multiple linear regression modeling,while those of the rest 16 were employed for the verifica-tion of the established model.Results Based on the data of 65 athletes,the multiple linear regression equation of VO2max was:VO2max=2616.661+60.389×lean body mass(kg)-3.108×3000-meter run-ning time(s)-16.665×lower limb length A(cm)+6.356×maximum heart rate(bpm),R2=0.858,and that of the relative VO2max was:relative VO2max=119.685-0.058×3000-meter running time(s)-0.224×body weight(kg)-0.452×Achilles tendon length(cm),R2=0.681.Accord-ing to the data of the rest 16 athletes,there was no significant difference in the calculated values of VO2max and relative VO2max.Moreover,the calculated values and the direct test values of VO2max and rel-ative VO2max were positively correlated(r=0.735,P=0.001;r=0.509,P=0.044).Conclusion A regression model of VO2max and relative VO2max for young male endurance athletes at altitude(1890 meters altitude high)was established and verified through direct testing.The model established is worth popularization and application,and can provide references for indicators selection of young male endurance athletes at altitude(1890 meters altitude high).
