摘　　要：目的:通过对女大学生的素食生活习惯研究,探讨女大学生的饮食内容与运动能力的关系。方法:2002级沈阳工业大学食素1年以上的女大学生36名(素食组)和非食素女大学生40名(非素食组)通过西德Jaeger公司生产的运动心肺功能仪(功率自行车)对运动期间心率、摄氧量、每博摄氧量(VO2/HR)、最大摄氧量(VO2max)、每博最大摄氧量(VO2max/HP)、最大运动负荷(WATTmax)、呼吸商等进行观察统计。结果:在达到无氧阈(呼吸商=1)时,两组间的摄氧量、VO2/HR和WATT差异有显著性(P<0.001),食素组各项指标均明显低于非食素组。在观察两组学生在达到VO2max时,食素学生和非食素学生在VO2max、呼吸商、VO2max/HR和WATTmax差异非常显著(P<0.01),食素女生的呼吸商明显高于非食素女生,而非食素女生的VO2max,VO2max/HR和WATTmax三项指标却明显高于食素女生。结论:在机体承受较强运动负荷的状况下,素食者的心肺功能各项指标低于非食素者,运动能力降低。AIM:To investigate the relationship between dietary contents and motor ability of female university students by studying their habit of vegetable diet. METHODS:Thirty-six female students with the habit of vegetable diet for over one year(vegetarian group) and 40 female students who were not vegetarians(non-vegetarian group) of Shenyang University of Technology(entered the university in 2002) were involved in this study.Their heart rate(HR),oxygen consumption(VO2),VO2 per beat(VO2/HR),the maximal VO2(VO2max), the VO2max per beat(VO2max/HR),the maximal work load(WATTmax) and respiratory quotient(RQ) during exercise were observed by using the exercise cardiorespiratory function machine(cycle ergometer) produced by the West Germany Jaeger Company. RESULTS:When anaerobic threshold(AT)(RQ=1),VO2, VO2/HR and WATT were significantly lower in the vegetarian group than in the non-vegetarian group(P< 0.001). There were very significant differences in the VO2max, RQ, VO2max/HR and WATTmax between the two groups when reached VO2max(P< 0.01),RQ in the vegetarian group was obviously higher than that in the non-vegetarian group, while the VO2max,VO2max/HR and WATTmax were remarkably higher than in the vegetarian group. CONCLUSION:When the organs are under more intensive work load,the indexes of cardiopulmonary function are lower in the vegetarians than in the non-vegetarians,and their motor ability is decreased.
