The optimal approach to prescribing resistance training (RT) combined with aerobic training (AT) for psychosocial and health-related quality of life (HRQOL) is unclear.
To compare the effects of AT combined with RT (1 versus 3 sets) versus AT alone on HRQOL and psychosocial outcomes.
Subjects (N.=72) were randomized to AT (5 d∙wk-1) or AT (3 d∙wk-1) with either 1 set (AT/RT1) or 3 sets (AT/RT3) of RT performed 2 d∙wk-1.
Outpatient Cardiac Rehabilitation Program.
Subjects with coronary artery disease.
HRQOL and psychosocial parameters were assessed before and after 29 weeks of training by questionnaire.
Fifty-three subjects (mean±SD age 60.6±10.6 years) completed training. There was a group effect for change in self-efficacy of lower body physical activity tasks (P=0.03) with significantly greater improvement for AT/RT3 than AT alone (17.5±16.6% vs. 3.2±12.8% respectively, p=0.04). Lower body self-efficacy improved for AT/RT1 (15.5±13.8%, p<0.001) but not for AT alone (P=0.2). Self-efficacy for upper body tasks improved with AT/RT3 (18.2±19.9%, P=0.003) and AT/RT1 training (12.6±15.8%, P=0.005) but not with AT alone (8.3±16.1%, P=0.1). AT/RT3 and AT/RT1 training yielded improvements in depression score (-4.0±7.7, P=0.04 and -3.0±5.1, P=0.02 respectively) but not with AT alone (-0.5±4.7, P=0.71). The improvement from baseline in physical HRQOL score (MOS, SF-36) averaged 8.2±11.2% for AT (P=0.04), 10.4±11.9% for AT/RT1 (P=0.006) and 12.0±12.9% for AT/RT3 (P=0.004).
Both AT+RT groups with either 1 or 3 sets (AT 3 d∙wk-1and RT 2 d∙wk-1) each yield more pronounced psychosocial and HRQOL adaptations than AT alone (5 d∙wk-1). RT prescription beyond 1 set may further augment selected parameters in cardiac patients.
These results provide further rationale to develop combined AT+RT regimens for individuals with coronary artery disease.
对于将抗阻训练（RT）与有氧训练（AT）相结合以改善心理社会及健康相关生活质量（HRQOL）的最佳方法尚不清楚。
比较AT联合RT（1组与3组）与单纯AT对HRQOL和心理社会结局的影响。
将72名受试者随机分为单纯AT组（每周5天）或AT（每周3天），同时进行每周2天的RT，RT分别为1组（AT/RT1）或3组（AT/RT3）。
门诊心脏康复项目。
冠心病患者。
通过问卷调查在训练29周前后评估HRQOL和心理社会参数。
53名受试者（平均±标准差年龄60.6±10.6岁）完成了训练。在下肢身体活动任务的自我效能感变化方面存在组间效应（P = 0.03），AT/RT3组的改善明显大于单纯AT组（分别为17.5±16.6%对3.2±12.8%，p = 0.04）。AT/RT1组的下肢自我效能感有所改善（15.5±13.8%，p<0.001），而单纯AT组未改善（P = 0.2）。上肢任务的自我效能感在AT/RT3组（18.2±19.9%，P = 0.003）和AT/RT1组训练后（12.6±15.8%，P = 0.005）有所改善，而单纯AT组未改善（8.3±16.1%，P = 0.1）。AT/RT3组和AT/RT1组训练后抑郁评分有所改善（分别为-4.0±7.7，P = 0.04和-3.0±5.1，P = 0.02），而单纯AT组未改善（-0.5±4.7，P = 0.71）。身体HRQOL评分（MOS，SF - 36）从基线的改善平均值在AT组为8.2±11.2%（P = 0.04），AT/RT1组为10.4±11.9%（P = 0.006），AT/RT3组为12.0±12.9%（P = 0.004）。
AT + RT组（1组或3组，AT每周3天且RT每周2天）比单纯AT组（每周5天）产生更显著的心理社会和HRQOL适应性变化。超过1组的RT处方可能会进一步增强心脏病患者的某些参数。
这些结果为为冠心病患者制定联合AT + RT方案提供了进一步的理论依据。
