目的:采用定量定强度的运动干预方法,探讨运动量和强度等运动因素对心肺耐力的改善作用,并进一步验证运动干预模式的有效性。方法:以58名40~49岁中年男性为研究对象,随机分为对照组、小量中等强度组、小量大强度组和大量大强度组,小量和大量分别为1200和2000keal/wk;中等强度和大强度分别为40%~55%和65%~80%VO2 max。在12周运动中对运动量和强度进行精确监控,对运动干预前后心肺耐力指标进行测试并作相关比较分析。结果:1)坚持率分别为58.3%、53.3%和54.1%,运动量分别为14km、16km、21km,运动时间分别为149min、134min和183min,干预效果良好;2)3组实验组VO2 max分别增加了1ml/k/min(4%)、4.64ml/kg/min(15.8%)和5.4ml/kg/min(37.6%),与对照组比较,实验组均产生显著性差异(P〈0.05);大强度组出现非常显著性差异(P〈0.01)。结论:采用12周的运动干预模式可以引起心肺耐力水平显著改善,但是运动量对VO2 max水平的改善不明显,强度要比量更有利于VO2 max水平的提高,强度是引起VO2 max提高的主要因素;采用强度在40%VO2 max以上,每周运动量为16km或150min的运动,就足以引起VO2 max水平产生显著性改善,要想获得更多的身体健康效益,可以采用强度为65%~80%VO2 max每周运动量为16~21km或135~180min的运动.
目的:採用定量定彊度的運動榦預方法,探討運動量和彊度等運動因素對心肺耐力的改善作用,併進一步驗證運動榦預模式的有效性。方法:以58名40~49歲中年男性為研究對象,隨機分為對照組、小量中等彊度組、小量大彊度組和大量大彊度組,小量和大量分彆為1200和2000keal/wk;中等彊度和大彊度分彆為40%~55%和65%~80%VO2 max。在12週運動中對運動量和彊度進行精確鑑控,對運動榦預前後心肺耐力指標進行測試併作相關比較分析。結果:1)堅持率分彆為58.3%、53.3%和54.1%,運動量分彆為14km、16km、21km,運動時間分彆為149min、134min和183min,榦預效果良好;2)3組實驗組VO2 max分彆增加瞭1ml/k/min(4%)、4.64ml/kg/min(15.8%)和5.4ml/kg/min(37.6%),與對照組比較,實驗組均產生顯著性差異(P〈0.05);大彊度組齣現非常顯著性差異(P〈0.01)。結論:採用12週的運動榦預模式可以引起心肺耐力水平顯著改善,但是運動量對VO2 max水平的改善不明顯,彊度要比量更有利于VO2 max水平的提高,彊度是引起VO2 max提高的主要因素;採用彊度在40%VO2 max以上,每週運動量為16km或150min的運動,就足以引起VO2 max水平產生顯著性改善,要想穫得更多的身體健康效益,可以採用彊度為65%~80%VO2 max每週運動量為16~21km或135~180min的運動.

Objective:Through a defined exercise trial is a randomized controlled clinical trial designed to study the effects of exercise training regimens differing in dose (kcal/wk) or intensity (VO2 max), this study discuss the effect of dose exercise on cardiorespiratory fitness (CRF) and examine the validity of exercise intervention. Methods: A total of 58 sedentary subjects aged 40-49yr were assigned to participate for 12 weeks in a control group or in one of three exercise groups:l) low volume/moderate intensity (LVMI, equivalent of 1 200 kcal/wk at 40%-55% VO2 max,2) low volume/vigorous intensity (LVVI, 1 200 kcal/wk at 65%- 80% VO2 max) and 3) high volume/vigorous intensity (HVVI, 2 000 kcal/wk at 65%- 80% VO2 max). Subjects who complied with these guidelines served as the basis for the main analysis, CRF were tested before and after 12 weeks training. Results:Rate of adherence of all exercise groups were 58.3 %, 53.3 % and 54.1 % respectively, the effect of intervention was favorable. In contrast, all exercise groups increased VO2max compared to the baseline, VO2 max increased significantly(P〈0.05) in exercise groups, 4%, 15. 8% and 17. 6% respectively. Conclusion: 12 weeks of dose exercise intervention improves cardiorespiratory fitness significantly. It appears that moderate dose of training for 16 km or 150 min of exercise with 40%- 55% VO2 max intensity was sufficient to get health outcomes. However, an exercise prescription that incorporated 135 -180 min or 16- 21 km of exercise with 65% - 80% VO2 max intensity will be better, And it seem that VO2 max was respond to intensity not volume.
