This study compares energy expenditure, body composition, and metabolic rate between serial (SCG) and integrated (ICG) combined training in untrained middle-aged obese males. Method: Twenty untrained obese males (age: 50 ± 3 years) were randomly assigned to a SCG ( = 10) or an ICG ( = 10). Both groups completed a 3-month training program (3 sessions/week) consisting of walking and bodyweight exercises, differing only in the sequence of aerobic and strength training. In SCG, strength training was performed before aerobic training, while in ICG, aerobic and strength exercises alternated in a predetermined order.
After a 3-month training period, both groups significantly improved all health indices compared to pre-training values ( < 0.005, = 0.40-2.71), indicating small to large effects. Specifically, there were moderate reductions in body fat percentage, small decreases in body circumferences, and moderate-to-large reductions in arterial blood pressure and resting heart rate. Additionally, respiratory function showed a large improvement. No significant differences were observed between SCG and ICG in energy expenditure, resting metabolic rate, total daily energy expenditure, macronutrient composition, or health indices after the intervention ( > 0.05).
In conclusion, both SCG and ICG are effective strategies for improving metabolic health, respiratory function, and body composition in middle-aged obese males. These findings highlight the flexibility of combined training approaches in promoting overall health and fitness in this population and suggest that both combined training programs can be implemented in structured exercise programs to promote cardiometabolic health in middle-aged adults.
本研究比较了未经训练的中年肥胖男性进行连续（SCG）和综合（ICG）联合训练后的能量消耗、身体成分和代谢率。方法：20名未经训练的肥胖男性（年龄：50±3岁）被随机分为SCG组（n = 10）或ICG组（n = 10）。两组均完成了为期3个月的训练计划（每周3次训练），包括步行和体重训练，仅有氧训练和力量训练的顺序不同。在SCG组中，力量训练在有氧训练之前进行，而在ICG组中，有氧和力量训练按预定顺序交替进行。
经过3个月的训练期后，与训练前相比，两组所有健康指标均显著改善（P < 0.005，效应量 = 0.40 - 2.71），表明效果从小到大都有。具体而言，体脂百分比有中度降低，身体周长有小幅下降，动脉血压和静息心率有中度至大幅降低。此外，呼吸功能有大幅改善。干预后，SCG组和ICG组在能量消耗、静息代谢率、每日总能量消耗、宏量营养素组成或健康指标方面未观察到显著差异（P > 0.05）。
总之，SCG和ICG都是改善中年肥胖男性代谢健康、呼吸功能和身体成分的有效策略。这些发现突出了联合训练方法在促进该人群整体健康和体能方面的灵活性，并表明这两种联合训练方案都可用于结构化运动计划中，以促进中年成年人的心脏代谢健康。
