This study aimed to compare the effects of high-intensity interval training (HIIT) combined with resistance training (RT) versus HIIT alone on body composition, cardiorespiratory fitness and glycolipid metabolism in young women with overweight/obesity.
This randomized controlled trial divided 40 subjects into an experimental group (HIIT+RT) and a control group (HIIT). Both groups underwent training three times per week for eight weeks. Body composition, cardiorespiratory fitness and glycolipid levels were assessed before and after the intervention.
The results revealed that compared to baseline, both the experimental and control groups showed significant improvements in body weight, body mass index (BMI), Body fat, waist circumference (WC), waist-hip ratio (WHR), peak oxygen uptake (VOpeak), vital capacity (VC), oxygen pulse (VO/HR), minute ventilation, resting heart rate, blood oxygen saturation, blood pressure, fasting blood glucose, triglycerides and high-density lipoprotein cholesterol (<0.05). Additionally, a significant increase in muscle mass and a significant reduction in 2-hour postprandial glucose were observed in the experimental group (<0.05). Muscle mass (mean difference: 2.75%), VOpeak (mean difference: 1.61 mL/min/kg), VC (mean difference: 334mL), and VO/HR (mean difference: 0.51mL/beat) showed greater improvement in the HIIT+RT group compared to the HIIT group (<0.05).
In conclusion, an 8-week regimen of either combined HIIT and RT or HIIT significantly improves body composition, cardiorespiratory fitness and glycolipid metabolism in women with overweight/obesity. However, the combined training appears to offer more benefits than HIIT alone. Further research is needed to evaluate the long-term effects and feasibility of combined training.

本研究旨在比较高强度间歇训练（HIIT）联合抗阻训练（RT）与单纯 HIIT 对超重/肥胖年轻女性身体成分、心肺功能和糖脂代谢的影响。
这项随机对照试验将 40 名受试者分为实验组（HIIT+RT）和对照组（HIIT）。两组均每周训练 3 次，共 8 周。干预前后评估身体成分、心肺功能和糖脂水平。
与基线相比，实验组和对照组的体重、体重指数（BMI）、体脂肪、腰围（WC）、腰臀比（WHR）、峰值摄氧量（VOpeak）、肺活量（VC）、氧脉搏（VO/HR）、分钟通气量、静息心率、血氧饱和度、血压、空腹血糖、甘油三酯和高密度脂蛋白胆固醇均显著改善（<0.05）。此外，实验组还观察到肌肉量显著增加，餐后 2 小时血糖显著降低（<0.05）。与 HIIT 组相比，HIIT+RT 组的肌肉量（平均差异：2.75%）、VOpeak（平均差异：1.61 mL/min/kg）、VC（平均差异：334mL）和 VO/HR（平均差异：0.51mL/beat）改善更为显著（<0.05）。
综上所述，8 周的 HIIT 联合 RT 或 HIIT 方案均可显著改善超重/肥胖女性的身体成分、心肺功能和糖脂代谢。然而，联合训练似乎比单纯 HIIT 更有优势。需要进一步研究来评估联合训练的长期效果和可行性。
