摘　　要：目的探讨不同剂量的有氧运动对习惯久坐大学生微循环功能的影响,为指导大学生科学体育干预性行为提供参考。方法招募湖北民族大学在校生69名,分成运动A组、运动B组和对照组,每组各23人(男生12名,女生11名)。运动组进行12周有氧运动干预,其中A组每周运动1~2次,B组每周运动≥3次,对照组不进行任何系统性的体育运动。分别在试验前、试验后对3组受试者微血管反应、经皮氧分压(TcpO_(2))、一氧化氮(NO)、一氧化氮合酶(NOS)及内皮素-1(ET-1)进行测试。结果试验后,微血管反应性呈现出组别和时间交互作用(P=0.00),其中运动B组大于对照组及运动A组(P<0.01),运动A组与对照组差异无统计学意义(P>0.05),但经皮氧分压不具有时间与组别的交互作用(P=0.53);NO(F=6.32),NOS(F=7.91)具有组别和时间交互作用,其中运动B组大于对照组及运动A组(P<0.01),运动A组与对照组差异无统计学意义(P>0.05)。结论有氧运动影响身体微血管反应及内源性NO水平,持续12周、每周≥3次的有氧运动能通过促进内源性NO的生成提高久坐大学生微血管反应性,但每周1~2次的有氧运动对微血管反应性无显著影响。Objective To investigate the effects of different doses of aerobic exercise on the microvascular function of habitually sedentary college students.Methods A total of 69 students from Hubei Minzu University were recruited and divided into sports group A,sports group B and control group,with 23 students in each group(12 boys and 11 girls).The exercise group received 12 weeks of aerobic exercise intervention,in which group A exercised 1-2 times a week,group B exercised≥3 times a week,and the control group did not carry out any systematic sports.Microvascular response,Transcutaneous partial pressure of oxygen(TcpO_(2)),Nitric oxide,Nitric oxide synthase(NOS)and En-dothelin-1(ET-1)were measured before and after the test.Results After the test,the microvascular reactivity showed group and time interaction(P<0.01),in which exercise group B was greater than that of control group and exercise group A(P<0.01).There was no significant difference between exercise group A and control group(P>0.05),but the percutaneous partial pressure of oxygen(P=0.53)had no time interaction with other groups;NO(F=6.32)and NOS(F=7.91)had group and time interaction,in which exercise group B was greater than control group and exercise group A(P<0.01),and there was no significant difference between exercise group A and control group(P>0.05).Conclusion There is a"dose-effect"relationship between aerobic exercise and microcirculatory blood perfusion and endogenous NO.Continuous aerobic exercise≥3 times a week for 12 weeks improved microcirculatory blood perfusion and promoted endogenous NO production in sedentary college students,but doing aerobic exercise for 1-2 times a week had no significant effect on microcirculatory blood perfusion and endogenous NO.
