背景与目的：低容量、高强度间歇训练（HIIT）是否是一种改善代谢危险因素的适当运动方法尚存在争议。此外，不知道HIIT项目后进行短期低热量饮食干预（LCDi）是否会影响风险因素。本研究调查了8周，3次/周的运动干预（EXi），包括HIIT或中等强度连续训练（MICT），然后是4周的LCDi，如何影响危险因素。方法和结果：26名具有代谢危险因素的男性工人(47.4 +/- 7.1岁；心肺功能（（V)超过dotO（2峰值））28.5 +/- 3.9 ml/kg/min）被随机分配到HIIT组（3组3分钟循环，组间2分钟活动休息，180千卡）或MICT组（45分钟，360千卡）。EXi结束后，所有受试者参加为期4周的LCDi（4次咨询）。在EXi期间，HIIT（25.4 +/- 14.6%）比MICT（14.9 +/- 12.8%）改善（P < 0.05），而体脂和高密度脂蛋白胆固醇的改善相似。在LCDi期间，部分危险因素进一步改善（P < 0.05），组间差异无统计学意义，HIIT组(V) over dotO（2peak）下降至与MICT组相同水平（P < 0.05）。结论：尽管HIIT的运动量低于MICT，但在EXi期间，HIIT组的V) over dotO（2peak）比MICT组增加得更多，但HIIT的这一优势在去训练后迅速消失。干预策略包括8周的HIIT或MICT，然后是4周的LCDi，对代谢危险因素有积极影响。临床试验注册号：UMIN11352。(C) 2015 Elsevier B.V.版权所有
Background and aims: Whether low-volume, high-intensity, interval training (HIIT) is an adequate exercise method for improving metabolic risk factors is controversial. Moreover, it is not known if performing a short-term, low-calorie diet intervention (LCDi) after a HIIT program affects risk factors. This study investigated how an 8-week, 3 times/week exercise intervention (EXi) incorporating either HIIT or moderate-intensity continuous training (MICT) followed by a 4-week LCDi affects risk factors.Methods and results: Twenty-six male workers with metabolic risk factors (47.4 +/- 7.1 years; cardiorespiratory capacity ((V) over dotO(2peak)) of 28.5 +/- 3.9 ml/kg/min) were randomly assigned to either the HIIT (3 sets of 3-min cycling with a 2-min active rest between sets, 180 kcal) or MICT (45 min, 360 kcal) group. After the EXi, all subjects participated in a 4-week LCDi (4 counseling sessions). During the EXi, (V) over dotO(2peak) improved more (P < 0.05) through HIIT (25.4 +/- 14.6%) than through MICT (14.9 +/- 12.8%), whereas improvements in body fat and HDL cholesterol were similar. During the LCDi, some risk factors improved further (P < 0.05) without any group differences, while (V) over dotO(2peak) in the HIIT group decreased (P < 0.05) to the same level as in the MICT group.Conclusion: (V) over dotO(2peak) increased more with HIIT than with MICT during the EXi despite HIIT having a lower exercise volume than MICT, but this advantage of HIIT promptly disappeared through detraining. An intervention strategy consisting of 8 weeks of either HIIT or MICT followed by a 4-week LCDi has a positive effect on metabolic risk factors. Clinical Trial Registration: UMIN11352.
