[摘要] 目的 探讨有氧运动对肺活量体重指数不及格大学生人群甲襞微循环的影响。方法 按照入校体格健康普查标准,随机抽取2017级新生500名健康个体作为研究对象,以肺活量指数不合格的50名大学生作为测试实验对象,观察50名实验对象有氧运动后的肺活量指数及有氧运动前后的甲襞微循环功能变化。其中20名为男生组,30名为女生组。结果 相较于运动前,肺活量不及格中的20名男生运动后肺活量指数明显提[(54.71±3.76)vs(48.73±3.36)(t=8.846)] ,差异有统计学意义(P<0.05);而肺活量不及格中的30名女生运动后肺活量指数也明显提高[(45.00±3.67)vs(38.23±2.93)(t=12.172)] ,差异有统计学意义(P<0.05)。相较于运动前,20名男生运动后甲襞微循环形态积分有改善 [(0.78±0.69)vs(1.27±1.12)(t=2.423)] ,差异有统计学意义(P<0.05);流态积分有改善 [(0.32±0.40)vs(0.6±0.53)(t=2.732)] ,差异有统计学意义(P<0.05);总积分有明显改善[(1.17±0.71)vs(1.93±1.02)(t=2.931)] ,差异有统计学意义(P<0.05)。同样30名女生运动后甲襞微循环形态积分有明显改善 [(1.01±0.75)vs(1.83±1.23)(t=3.255)] (P<0.01);总积分有改善[(1.50±0.99)vs(2.19±1.16)(t=2.696)] ,差异有统计学意义(P<0.05)。女生组运动前后甲襞微循环流态积分和襻周积分的差异无统计学意义(P>0.05)。结论 有氧运动能有效提高肺活量指数不合格大学生人群的肺活量指数,并对改善其微循环功能有一定的影響。

[Abstract] Objective This paper tries to investigate the effect of aerobic exercise on nailfold microcirculation in college students with poor vital mass index. Methods According to the physical health screening standards, 500 healthy individuals of 2017 freshmen were randomly selected as research objects. 50 college students whose vital capacity index was not qualified were selected as test subjects. The changes of vital capacity index after aerobic exercise and nailfold microcirculation function before and after aerobic exercise were observed among 50 subjects. There were 20 boys and 30 girls. Results Compared with those before exercise, the vital capacity index of 20 boys with poor vital capacity was significantly increased after exercise [(54.71±3.76) vs (48.73±3.36) (t=8.846)] the difference was statistically significant(P<0.05). In addition, 30 female students with failing vital capacity also showed significant improvement in their vital capacity index after exercise [(45.00±3.67) vs (38.23±2.93) (t=12.172)]the difference was statistically significant(P<0.05). Compared with before exercise, 20 boys showed improvement in nailfold microcirculation morphological scores after exercise [(0.78±0.69) vs (1.27±1.12) (t=2.423)] the difference was statistically significant(P<0.05). Flow pattern integral improved [(0.32±0.40) vs (0.6±0.53) (t = 2.732)]the difference was statistically significant(P<0.05); Total score significantly improved [(1.17±0.71) vs (1.93±1.02) (t = 2.931)]the difference was statistically significant(P<0.05). Similarly, 30 female patients showed significant improvement in nailfold microcirculation morphological scores after exercise [(1.01±0.75) VS (1.83±1.23) (t=3.255)] (P<0.01). Total score improved [(1.50±0.99) vs (2.19±1.16) (t=2.696)] the difference was statistically significant(P<0.05) There was no statistically significant difference in nailfold microcirculation and loop integral before and after exercise in the female group (P>0.05). Conclusion Aerobic exercise can improve the vital capacity index of the unqualified college students and improve their microcirculation function.

根据国家心血管病中心发布的《中国心血管病报告2017》显示,目前我国心血管病患者约有2.9亿人,发病人数仍在持续增加,是我国居民最主要的死亡原因。甲襞微循环作为机体末梢微循环的一部分,其直接参与皮肤及其附属组织的物质交换,并参与体温的调节。甲襞微循环的变化可在一定程度上间接反映出全身微循环的变化,因此甲襞被称为观机体察微循环障碍的最佳窗口[1]。尤其是微血栓的检测一般的X光、B超、心电图发现不了,在显微电视屏幕上却清晰可见。

肺活量/体重指数(肺活量指数)是人体自身的肺活量与体重的比值,即=肺活量(mL)/体重(kg),目的是消除体格因素对肺功能的影响。生理学研究表明:人体的各钟生命活动都需要氧气,机体只有在氧供应充足的情况下才能正常工作,而机体内部的氧供给全部靠肺的呼吸获得,这是检测肺功能的最直观、最客观的指标。……
