ABSTRACT
Introduction
Due to economic development and technological progress, more attention has been given to intellectual education in detriment of physical conditioning, a phenomenon that has corroborated to raise obesity to a contemporary concern in public health. In this sense, studies that can provide reference to guide the scientific sport intervention behavior of college students are the focus of the current research.
Objective
Explore the effect of different doses of aerobic exercise on microcirculation function in sedentary college students.
Methods
69 students from Minzu University were recruited and randomly divided into exercise groups A, B and control. The exercise group received 12 weeks of aerobic exercise intervention. Among them, group A practiced 1-2 times per week, group B practiced ≥ 3 times per week. The control group did not practice any sport.
Results
After testing, microvascular reactivity showed an interaction to group and time (p<0.01). Among them, exercise group B was higher than control group and exercise group A (p<0.01), with no significant differences between exercise group A and control group (p>0.05).
Conclusion
Aerobic exercise affects body microvascular response and endogenous NO level. Aerobic exercise lasting 12 weeks with frequency equal to or greater than three times per week can improve the microvascular response of sedentary college students by promoting endogenous NO production. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
