Abstract：
This systematic review is conducted to evaluate the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on body composition and cardiorespiratory fitness (CRF) in the young and middle-aged.
Seven databases were searched from their inception to 22 October 2022 for studies (randomized controlled trials only) with HIIT and MICT intervention. Meta-analysis was carried out for within-group (pre-intervention vs. post-intervention) and between-group (HIIT vs. MICT) comparisons for change in body mass (BM), body mass index (BMI), waist circumference (WC), percent fat mass (PFM), fat mass (FM), fat-free mass (FFM), and CRF.
A total of 1738 studies were retrieved from the database, and 29 studies were included in the meta-analysis. Within-group analyses indicated that both HIIT and MICT can bring significant improvement in body composition and CRF, except for FFM. Between-group analyses found that compared to MICT, HIIT brings significant benefits to WC, PFM, and VO2peak.
The effect of HIIT on fat loss and CRF in the young and middle-aged is similar to or better than MICT, which might be influenced by age (18-45 years), complications (obesity), duration (>6 weeks), frequency, and HIIT interval. Despite the clinical significance of the improvement being limited, HIIT appears to be more time-saving and enjoyable than MICT.

摘要：
这项系统评价旨在评估高强度间歇训练（HIIT）和中等强度连续训练（MICT）对中青年身体成分和心肺适应性（CRF）的影响。
从开始到2022年10月22日搜索了七个数据库，以进行HIIT和MICT干预的研究（仅随机对照试验）。在组内进行Meta分析(干预前vs.干预后)和组间(HIIT与MICT)体重变化(BM)的比较，体重指数（BMI），腰围（WC），脂肪质量百分比（PFM），脂肪量（FM），无脂质量（FFM），和CRF。
从数据库中检索到总共1738项研究，29项研究纳入荟萃分析.组内分析表明，HIIT和MICT都可以显著改善身体成分和CRF，除了FFM。组间分析发现，与MICT相比，HIIT给WC带来了巨大的好处，PFM,和VO2peak。
HIIT对中青年减脂和CRF的影响与MICT相似或更好，这可能会受到年龄（18-45岁）的影响，并发症（肥胖），持续时间（>6周），频率,和HIIT间隔。尽管改善的临床意义有限，HIIT似乎比MICT更节省时间和享受。
