摘要

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(TcpO₂)、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。

Abstract: 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(TcpO₂), 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.
