High Intensity training (HIT) is a time-effective alternative to traditional exercise programs in adults with obesity, but the superiority in terms of improving cardiopulmonary fitness and weight loss has not been demonstrated.
to determine the effectiveness of HIT on cardiopulmonary fitness and body composition in adults with obesity compared to traditional (high volume continuous) exercise.
A systematic search of the main health science databases was conducted for randomized controlled trials comparing HIT with traditional forms of exercise in people with obesity. Eighteen studies were included in the meta-analysis. The (unstandardized) mean difference of each outcome parameters was calculated and pooled with the random effects model.
HIT resulted in greater improvement of cardiopulmonary fitness (VO) (MD 1.83, 95% CI 0.70, 2.96, p<0.005; I=31%) and a greater reduction of %body fat (MD -1.69, 95% CI -3.10, -0.27, p=0.02, I=30%) compared to traditional exercise. Overall effect for BMI was not different between HIT and traditional exercise.
Training at high intensity is superior to improve cardiopulmonary fitness and to reduce %body fat in adults with obesity compared to traditional exercise. Future studies are needed to design specific HIT programs for the obese with regard to optimal effect and long-term adherence.
高强度训练（HIT）是肥胖成年人传统运动方案的一种省时替代方案，但在改善心肺适能和减重方面的优越性尚未得到证实。
确定与传统（大量持续）运动相比，高强度训练对肥胖成年人心肺适能和身体成分的有效性。
对主要健康科学数据库进行系统检索，以查找比较高强度训练与传统运动形式对肥胖人群影响的随机对照试验。18项研究纳入荟萃分析。计算每个结局参数的（未标准化）平均差异，并采用随机效应模型进行汇总。
与传统运动相比，高强度训练在改善心肺适能（VO）方面效果更佳（平均差1.83，95%置信区间0.70，2.96，p<0.005；I²=31%），且在降低体脂百分比方面效果更显著（平均差-1.69，95%置信区间-3.10，-0.27，p=0.02，I²=30%）。高强度训练与传统运动在体重指数的总体效果上无差异。
与传统运动相比，高强度训练在改善肥胖成年人的心肺适能和降低体脂百分比方面更具优势。未来需要开展研究，针对肥胖人群设计特定的高强度训练方案，以实现最佳效果和长期依从性。
