【摘要】：目的:探討不同方式的健步走對邊緣性血脂升高中年男性腦力勞動者血脂及肺功能的影響。方法:選取西安市3所高校從事腦力勞動的科研工作者,篩選出符合(血脂水平分層標(biāo)準(zhǔn))邊緣性血脂升高標(biāo)準(zhǔn)的受試者48人,隨機分成勻速組和變速組各24人,實施為期12周的健步走。2組采用的運動強度:勻速組在第2和第3個10~15 min以60%~70%HRmax為主,變速組以60%~70%HRmax和70%~80%HRmax為主,每周4次,每次40~60 min。監(jiān)測受試者運動前、運動4周、運動12周的血脂六項(TC、TG、HDL-C、LDL-C、Apoa1/Apob)和肺通氣功能指標(biāo)(VC、FVC、FEV1/FVC%、MVV、VC/Kg)。結(jié)果:1)與運動前比較,運動6周,勻速組血脂及肺通氣功能各指標(biāo)無顯著性變化(P0.05);變速組TC顯著降低(P0.05),FEV1/FVC%、MVV、VC/Kg顯著升高(P0.05)。運動12周,勻速組TC、TG顯著降低(P0.05),FEV1/FVC%、MVV、VC/Kg顯著增高(P0.05);變速組血脂(除Apoa1/Apob外)和肺功能(除FVC外)指標(biāo)均有顯著差異(P0.01或P0.05)。2)組間比較:運動6周,2組血脂與肺功能各指標(biāo)無顯著性差異(P0.05);運動12周,具有顯著性差異(P0.05)的指標(biāo)為HDL-C、LDL-C、MVV。3)在不同的運動周期,血脂和肺功能指標(biāo)的變化幅度均有顯著性,運動12周明顯優(yōu)于運動6周,變速組變化幅度優(yōu)于勻速組。結(jié)論:1)勻速健步走12周,具有明顯的調(diào)脂效果和提高肺通氣功能;變速健步走6周,對血脂異常和肺通氣功能有顯著的改善;運動12周,調(diào)脂效果非常顯著,基本回歸正常范圍,肺功能顯著提高。2)強度較高的變速運動對血脂異常的調(diào)脂效果和肺通氣功能的提高顯著優(yōu)于勻速運動。
[Abstract]:Objective: to investigate the effects of different walking methods on the blood lipid and lung function in middle aged male mental workers. Methods: a total of 48 subjects were selected from 3 universities in Xi'an who were engaged in mental labor, and 48 subjects who met the criteria of blood lipid level stratification were randomly divided into uniform group and variable speed group, 24 subjects in each group were randomly divided into two groups: the control group (n = 24) and the control group (n = 24). The exercise intensity of the 12-week walking group was as follows: at the 2nd and 3rd 1015 min in the uniform group, 60-70HRmax was used mainly, while in the variable speed group, it was 600.70HRmax and 7080HRmax, mainly four times a week, 40 minutes and 60 minutes per week. Before exercise, 4 weeks and 12 weeks of exercise, the subjects were monitored for six items of blood lipids (TCU TGG, HDL-Cn, LDL-CU Apoa1 / Apob) and pulmonary ventilation function index (VCV FVCU FEV1 / FVC1 / VCr / Kg). Results compared with before exercise, there were no significant changes in blood lipid and pulmonary ventilation function in the control group at 6 weeks (P0.05), while TC decreased significantly (P0.05) in the change of speed group (P0.05), and increased significantly in the FEV1 / FVC+ MVVC-1 / VC-1 group (P0.05). Exercise for 12 weeks, The TG of TCU decreased significantly (P0.05) in the uniform group (P0.05), and the serum lipid (except Apoa1/Apob) and pulmonary function (P0.01 or P0.05) were significantly higher in the change group than in the control group (P0.05): there was no significant difference between the two groups (P0.05) in blood lipid and lung function at 6 weeks after exercise (P0.05), while at 12 weeks, there was no significant difference between the two groups (P0.05), and the difference between the two groups was not significant (P0.05), while in the control group there was significant difference (P0.01 or P0.05) in the indexes of blood lipids (except Apoa1/Apob) and pulmonary function (P0.01 or P0.05). There was significant difference (P0.05) in the changes of blood lipid and pulmonary function in different exercise cycle (P0.05), 12 weeks exercise was significantly better than 6 weeks exercise, the change range of change speed group was better than that of uniform speed group. Conclusion: (1) even walking for 12 weeks has obvious effect of regulating lipid and improving pulmonary ventilation function, changing speed walking for 6 weeks has significant improvement on dyslipidemia and pulmonary ventilation function, and for 12 weeks of exercise, the effect of lipid regulation is very significant. After returning to normal range, lung function was significantly increased by .2) the effect of hyperlipidemia on lipid regulation and lung ventilation function was significantly better than that of uniform exercise.
