有氧运动训练是公认的改善COPD患者功能能力的方法。疾病严重程度较高的人往往难以达到较高的有氧运动训练强度。在有氧训练之前进行阻力训练的效果进行了检查，以确定这种顺序方法是否与单独有氧训练或同时进行有氧训练和阻力训练相比，与功能状态的更大收益相关。患者随机分配至：1）序贯阻力然后有氧训练（RT-then-AT）（8周阻力训练，随后8周有氧运动训练），2）对照组（CE-then-AT+RT）（8周“假”训练，随后8周有氧和阻力训练），3）对照组（CE-then-AT）（8周“假”训练，随后8周有氧训练）。在进入研究时、第8周后和第16周后评估结果：有氧运动表现、肌肉力量和耐力。75例患者完成训练：FEV1%预测值40±10，V ~ 2 O2 peak %预测值71±22，去脂体重指数19.5±3.1。RT-then-AT比CE-then-AT+RT和CE-then-AT获得了更大的外周肌肉耐力，但有氧运动表现的改善相似。肌肉力量的改善在RT-然后-AT和CE-然后-AT+ RT之间是相似的。肌肉减少症与较差的出勤率、较低的有氧和阻力训练量相关。虽然与同时进行阻力和有氧训练相比，采用序贯方法进行阻力和有氧训练可使肌肉耐力和阻力训练量增加更多，但两组之间的其他训练结果相似，因此，在重度COPD中，序贯方法并不明显上级同时进行的方法。ClinicalTrials.gov标识符NCT 01058213。
Aerobic exercise training is a recognized approach for improving functional capacity in COPD. People with greater disease severity often have difficulty achieving higher aerobic exercise training intensity. The effects of resistance training prior to aerobic training were examined to determine if this sequential approach was associated with greater gains in functional status than aerobic training alone or concurrent aerobic and resistance training. Patients were randomized to: 1) sequential resistance then aerobic training (RT-then-AT) (8 weeks resistance training followed by 8 weeks aerobic exercise training), 2) control group (CE-then-AT+RT) (8 weeks of ‘sham’ training followed by 8 weeks concurrent aerobic and resistance training), 3) control group (CE-then-AT) (8 weeks ‘sham’ training followed by 8 weeks aerobic training). Outcomes were assessed at study entry, after week 8, and after week 16: aerobic exercise performance; muscle strength and endurance. 75 patients completed training: FEV1 %pred 40±10, V̇O2peak %predicted, 71±22, fat-free mass index 19.5±3.1. RT-then-AT had greater acquisition of peripheral muscle endurance than CE-then-AT+RT and CE-then-AT, but improvements in aerobic exercise performance were similar. Improvements in muscle strength were similar between RT-then-AT and CE-then-AT+RT. Sarcopenia was associated with poorer attendance, and lower aerobic and resistance training volumes. Although the sequential approach to resistance and aerobic training yielded a greater increase in muscle endurance and higher resistance training volume compared to concurrent resistance and aerobic training, other training outcomes were similar between the two groups, thus the sequential approach is not clearly superior to the concurrent approach in severe COPD.
