The main purpose of this study was to determine the differential effects of aerobic training (AT), resistance training (RT), and a combination of aerobic and resistance training (AT/RT) on changes in self-rated HrQoL measures, including the Short-Form 36 (SF-36) survey and Satisfaction with Physical Function and Appearance survey. We also sought to determine if combination training (AT/RT) has a more or less additive effect compared to AT or RT alone on self-rated HrQoL measures. Participants ( = 137) completed one of three 8-month exercise interventions: (1) AT: 14 kcal exercise expenditure per kg of body weight per week (KKW; equivalent to roughly 12 miles/week) at 65-80% of peak oxygen consumption; (2) RT: 3 days per week, 8 exercises, 3 sets per exercise, 8-12 repetitions per set; (3) AT/RT: full combination of the AT and RT interventions. The SF-36 survey, Satisfaction with Physical Function and Appearance survey, physical fitness, and anthropometrics were assessed at baseline and post-intervention. Paired -tests determined significant pre- vs. post-intervention scores within groups ( < 0.05). Analyses of covariance determined differences in change scores among groups ( < 0.05). On average, participants were 49.0 ± 10.6 years old, obese (BMI: 30.6 ± 3.2 kg/m), female (57.7%), and Caucasian (84.7%). Following the 8-month intervention, exercise groups improved peak VO (all groups), strength (RT and AT/RT), and anthropometric measures (AT and AT/RT). For the SF-36, RT ( = 0.03) and AT/RT ( < 0.001) significantly improved their physical component score; only AT/RT ( < 0.001) significantly improved their mental component score. Notably, all groups significantly improved both their satisfaction with physical function and appearance scores (All Groups: < 0.001 for both outcomes). We found that aerobic, resistance, or combination exercise training improves several components of self-rated HrQoL, including physical function, appearance, and mental well-being. : No. NCT00275145.
本研究的主要目的是确定有氧训练（AT）、抗阻训练（RT）以及有氧与抗阻联合训练（AT/RT）对自我评定的健康相关生活质量（HrQoL）指标变化的不同影响，这些指标包括简明健康调查问卷（SF-36）以及身体功能与外观满意度调查问卷。我们还试图确定联合训练（AT/RT）与单独的AT或RT相比，在自我评定的HrQoL指标上是否具有或多或少的累加效应。参与者（n = 137）完成了三种为期8个月的运动干预之一：（1）AT：每周每千克体重14千卡的运动消耗（KKW；约相当于每周12英里），运动强度为峰值耗氧量的65%-80%；（2）RT：每周3天，共8项运动，每项运动3组，每组8-12次重复；（3）AT/RT：AT和RT干预的完全组合。在基线和干预后评估SF-36调查问卷、身体功能与外观满意度调查问卷、身体素质和人体测量学指标。配对t检验确定组内干预前后得分的显著差异（P < 0.05）。协方差分析确定组间变化得分的差异（P < 0.05）。平均而言，参与者年龄为49.0±10.6岁，肥胖（体重指数：30.6±3.2kg/m²），女性（57.7%），高加索人（84.7%）。经过8个月的干预，运动组的峰值摄氧量（所有组）、力量（RT和AT/RT组）和人体测量学指标（AT和AT/RT组）均有所改善。对于SF-36，RT组（P = 0.03）和AT/RT组（P < 0.001）的身体成分得分显著提高；只有AT/RT组（P < 0.001）的心理成分得分显著提高。值得注意的是，所有组的身体功能和外观满意度得分均显著提高（所有组：两项结果的P均< 0.001）。我们发现，有氧训练、抗阻训练或联合运动训练可改善自我评定的HrQoL的几个方面，包括身体功能、外观和心理健康。试验编号：NCT00275145。
