摘要
[目的]测定322名男性在校大学生的体力劳动能力(PWC170)和最大摄氧量(VO2max),观察二者之间的关系。[方法]利用二级阶梯负荷实验法,通过测定心率变化,依据公式计算PWC170PWC170值和VO2max。[结果]PWC170x±s为(940.82±188.07)kg.m/min,其中优为21人、良为34人,二者共占17.08%;差为72人,占22.36%,与相关资料所叙述的部队医学院校学生的PWC170(1088.67±188.09)kg.m/min相比较均有明显的差异(P﹤0.01);VO2maxx±s为(43.41±3.68)ml/kg.min,其中优为12人、良为14人,二者共占8.07%;差为77人,占23.91%,与相关资料所叙述的部队医学院校学生的VO2max(44.54±6.01)ml/kg.min相比较差异无统计学意义(P﹥0.05);另外观察了PWC170优、良者,VO2maxx±s为(46.38±3.04)ml/kg.min,PWC170差者,VO2maxx±s为(39.34±2.67)ml/kg.min,经统计学处理,差异有统计学意义(P﹤0.01)。[结论]PWC170与VO2max有明确的相关关系;大学生的PWC170有待通过体育训练进一步提高。
[Objective] To determtne the PWC170 and VO2max of 322 undergraduates and observe the relation between them. [Methods] For determination of the heart rate, secondary-step load experimentation was performed. PWC170 and VO2max indices were calculated using proper mathematical equations. [ Results] The mean of PWC170 was 940.82±188.07kg.m/min. 21 and 34 of the subjects, who obtained a higher value and a medium value respectively, took up 17.08% while 72 of them, who obtained the lower value, covered 22.36%. The comparison of PWC170 indices showed significant differences between the subjects and the students in a military medical college recorded in relevant data whose PWC170 was 1088.67±188.09kg.m/min （P 〈 0.01 ）. The mean of VO2max was 43.41±3.68 ml/kg.min. 12 and 14 of the subjects, who obtained excellent value and good value respectively, took up 8.07%while 77 of them, who obtained the lower value, covered 23.91%. The comparison of VO2max indices showed no statistically significant differences between the subjects and the students in a military medical college recorded in relevant data whose VO2max was 44.54±6.01 mL/kg.min （P 〉 0.05）. Furthermore, the mean of VO2max of the students with excellent value and good value was 46.38±3.04 ml/kg.min while the mean of VO2max of the students with lower value 39.34±2.67 ml/kg.min, which showed statistically significant difference （P 〈 0.01）. [Conclusion] Results show there is a distinct relation between PWC170 and VO2max and a necessity to improve the PWC17 of the college students by physical exercise.
