摘　　要：目的：探讨机体在中等强度运动中能量代谢变化特征，为普通人群运动健身、减肥等锻炼模式提供实践依据。方法：采用德国产Cortex MetaMax 3B对20名普通大学生在个体55％最大摄氧量（VO2max）强度下，以气体代谢法监测60 min间歇跑运动中机体糖和脂肪能量消耗以及底物代谢变化特征，从环比和定基比的角度分析大学生在间歇跑中的机体供能特征。结果：男生运动至31～50 min段总输出量高于女生[（156．64±8．45） cal/（min· kg）＞（114．46±8．81） cal/（min· kg）；t＝6．965，P＜0．001]。第一个间歇期男女生糖、脂代谢差异无统计学意义，第二个间歇期男生糖供能量高于女生（t＝4．685，P＝0．001）。61～80 min段脂代谢环比值男女生差异有统计学意义（t＝3．643，P＝0．004）。结论：55％VO2max强度下男大学生糖代谢增长的速度和幅度均高于女生，而脂代谢相反。男女生糖脂肪供能百分比超过50％约在第2个间歇期后的10 min。Aim：To explore the energy metabolism characteristic in moderate-intensity exercises so as to provide prac-tical basis for the general population sports and fitness , weight loss and other exercise modes .Methods： Using Germany Cortex MetaMax 3B, the body sugar and fat and substrate metabolism variations of 20 college students under the 55%VO2max intensity, were monitored by gas metabolism during 60 min intermittent running ,and the energy metabolism charac-teristic was analyzed from the chain perspective ratio and fixed base ratio .Results： In 31-50 min, the total output of male students[（156.64 ±8.45） cal/（min· kg）] was greater than female students （114.46 ±8.81） cal/（min· kg）（t=6.965,P〈0.001）.In the first intermission, sugar and fat metabolism of males and females had no significant difference . In the second intermission , sugar metabolism for males was significantly greater than that for females （ t =4.685, P =0.001）.In the 61-80 min segment, the chain perspective ratio of lipid metabolism was significantly different between males and females（t=3.643,P=0.004）.Conclusion： Under 55%VO2max intensity, the increasing velocity and ampli-tude of sugar for males are faster than those for females , but the change of lipid is quite the reverse .The sugar and fat con-sumption exceeds 50%at 10 min after the 2nd intermission for both male and female students .
