【摘要】：目的:本研究通过设置不同的运动模式(快慢快、匀速、慢快慢),观察中年男性的肺通气功能和颈部血管的部分指标干预前后的反应,并讨论其内在适应机制,为中年男性人群提供科学合理有效的运动处方,很好的预防和改善由于呼吸系统、肺通气功能、颈动脉狭窄、变厚等引起的慢性疾病,为该群体科学健身提供参考依据。方法:向社会招募研究对象为陕西省西安市45-59岁从事脑力劳动者,经过问卷调查筛选,选出48人作为研究对象。随机分为快慢快组(K)、慢快慢组(M)、匀速组(Y)、对照组(D),受试者按照分组模式去运动,每周至少三次连续12周。对照组保持原有生活方式。干预后对受试者的肺通气功能指标肺活量VC(L)、用力肺活量FVC(L)、一秒率FEV1/FVC(%)、每分钟最大通气量MVV(L)和颈部血管指标血管内-中膜厚度IMT(mm)、颈动脉分叉BIF(mm)、颈总动脉内径CCA(mm)进行测试,将受试者干预前后各项指标数据采集整理分析,从而对比不同分组之间的健身效果。结果:(1)经过12周不同模式健步走运动干预后,快慢快组、匀速组受试者用力肺活量、肺活量、一秒率、每分最大通气量均呈现上升趋势,其中快慢快组一秒率和每分钟最大通气量对比干预前均有非常显著性变化(P0.01),其他实验组指标对比干预前无显著性差异变化(P0.05)。对照组干预后用力呼气肺活量、肺活量、一秒率均出现下降趋势,但对比干预前无显著性变化(P0.05)。(2)经过12周不同模式健步走运动干预后,三个实验组试验后受试者左右两侧的颈动脉内-中膜厚度和颈动脉分叉厚度均有下降趋势,其中快慢快组试验后对比干预前有显著性变化(P0.05)。慢快慢组试验后右侧颈动脉分叉呈非常显著性变化(P0.01)。慢快慢组干预颈总动脉内径效果最为明显。其他实验组指标对比干预前无显著性变化(P0.05)。对照组三项指标对比干预前均有上升趋势,但无显著性变化(P0.05)。结论:(1)通过研究发现为期12周不同模式健步走的运动干预,能有效提高中年男性人群用力肺活量、肺活量、一秒率以及每分最大通气量。以快慢快组的健步走运动干预效果最为明显。慢快慢组和匀速组效果依次减弱。(2)经过研究发现:在三个实验组中,快慢快组干预颈总动脉内—中膜厚度和颈动脉分叉厚度效果最为明显,以慢快慢组、匀速组效果依次减弱。以慢快慢组的干预方式对颈总动脉内径效果最为明显。
[Abstract]:Objective: to observe the lung ventilation function of middle-aged men and the responses of some indexes of cervical blood vessels before and after intervention by setting up different exercise modes (speed, speed, speed, slow, slow and slow), and to discuss the mechanism of adaptation. To provide scientific, reasonable and effective exercise prescription for middle-aged male population, to prevent and improve the chronic diseases caused by respiratory system, pulmonary ventilation function, carotid artery stenosis, thickening and so on. Methods: the subjects of the study were 45-59 years old people engaged in mental labor in Xi'an City of Shaanxi Province. 48 subjects were selected by questionnaire survey. They were randomly divided into two groups: the fast group, the slow group, the slow group, the uniform group, the control group, and the control group. The subjects exercised according to the group mode, at least three times a week for 12 weeks. The control group maintained the original lifestyle. The index data before and after intervention were collected and analyzed to compare the fitness effect between different groups. Results (1) after 12 weeks of intervention, the forced vital capacity, vital capacity, rate of one second, maximum ventilation volume of each minute in the fast, slow and fast group and the uniform speed group all showed an upward trend. The rate of one second and the maximum ventilation volume per minute in the fast slow and fast group were significantly different before intervention (P 0.01), but no significant difference was found in the other experimental groups before intervention (P 0.05). In the control group, forced expiratory vital capacity, vital capacity and rate of one second decreased, but there was no significant change before intervention. The IMT and carotid bifurcation thickness of the left and right sides of the subjects in the three experimental groups showed a downward trend after the experiment, and there was a significant change before and after intervention in the fast, slow and fast group. The bifurcation of the right carotid artery in the slow fast and slow group showed a very significant change after the test (P 0.01). The intervention of common carotid artery diameter in slow fast and slow group was the most obvious. There was no significant change in other experimental groups before intervention (P 0.05). The three indexes of the control group all showed an upward trend before intervention, but there was no significant change (P 0.05). Conclusion (1) through the study, we found that 12 weeks of exercise intervention in different modes of walking can effectively improve the forced vital capacity, vital capacity, second rate and maximum ventilation volume per minute in middle-aged male population. The intervention effect of the fast, slow and fast group was the most obvious. In the three experimental groups, the medial thickness of common carotid artery and the thickness of bifurcation of carotid artery were the most obvious in the fast, slow and fast group, but in the slow fast and slow group, the effect of uniform group was weakened in turn. The intervention of slow, slow and slow group had the most obvious effect on the internal diameter of common carotid artery.
