To observe the effects of aerobic exercise combined with resistance training on the cardiorespiratory fitness and exercise capacity of patients with stable coronary artery disease (CAD) . From June 2014 to December 2015, 73 patients with stable CAD in our department were recruited and randomly assigned to two groups: the control group (38) and the exercise group (35) . Patients in both groups received conventional medical treatment for CAD and related cardiac health education. While for patients in exercise group, a twelve-week aerobic exercise combined with resistance training program were applied on top of conventional treatment and health education. Cardiorespiratory fitness and exercise capacity were evaluated by cardiopulmonary exercise testing. (1) The exercise capacity was significantly increased in the exercise group after 12 weeks training as compared to baseline level: peak oxygen uptake per kilogram ( (26.25±5.14) ml·kg(-1)·min(-1) vs. (20.88±4.59) ml·kg(-1)·min(-1)) , anaerobic threshold ( (15.24±2.75) ml·kg(-1)·min(-1) vs. (13.52±2.92) ml·kg(-1)·min(-1)], peak oxygen pulse ( (11.91±2.89) ml/beat vs. (9.77±2.49) ml/beat) , peak Watts ( (113.2±34.0) W vs. (103.7±27.9) W) , peak metabolic equivalent ( (7.57±1.46) METs vs. (6.00±1.32) METs) (all 0.05 vs. baseline) . (2) The degree of improvement of peak oxygen uptake per kilogram ( (26.25±5.14) ml·kg(-1)·min(-1) vs. (22.32±4.00) ml·kg(-1)·min(-1)) , anaerobic threshold ( (15.24±2.75) ml·kg(-1)·min(-1) vs. (13.76±2.51) ml·kg(-1)·min(-1)) , peak oxygen pulse ( (11.91±2.89) ml/beat vs. (9.99±2.15) ml/beat) and peak metabolic equivalent ( (7.57±1.46) METs vs. (6.47±1.17) METs) were significantly higher in exercise group than in control group (all 0.05) . Aerobic training at an aerobic threshold level combined with Thera-band resistance training is safe for patients with stable coronary artery disease. This combined exercise program can significantly improve the cardiorespiratory fitness and exercise capacity of patients with stable coronary artery disease.
观察有氧运动联合抗阻训练对稳定型冠状动脉疾病(CAD)患者心肺适能及运动能力的影响。2014年6月至2015年12月,选取我科73例稳定型CAD患者,随机分为两组:对照组(38例)和运动组(35例)。两组患者均接受CAD常规药物治疗及相关心脏健康教育。运动组患者在常规治疗和健康教育基础上,进行为期12周的有氧运动联合抗阻训练计划。通过心肺运动试验评估心肺适能和运动能力。(1)运动组训练12周后运动能力较基线水平显著提高:每千克体重峰值摄氧量((26.25±5.14)ml·kg⁻¹·min⁻¹ 对比 (20.88±4.59)ml·kg⁻¹·min⁻¹)、无氧阈((15.24±2.75)ml·kg⁻¹·min⁻¹ 对比 (13.52±2.92)ml·kg⁻¹·min⁻¹)、峰值氧脉搏((11.91±2.89)ml/次对比(9.77±2.49)ml/次)、峰值功率((113.2±34.0)W对比(103.7±27.9)W)、峰值代谢当量((7.57±1.46)METs对比(6.00±1.32)METs)(均P<0.05对比基线)。(2)运动组每千克体重峰值摄氧量((26.25±5.14)ml·kg⁻¹·min⁻¹ 对比 (22.32±4.00)ml·kg⁻¹·min⁻¹)、无氧阈((15.24±2.75)ml·kg⁻¹·min⁻¹ 对比 (13.76±2.51)ml·kg⁻¹·min⁻¹)、峰值氧脉搏((11.91±2.89)ml/次对比(9.99±2.15)ml/次)及峰值代谢当量((7.57±1.46)METs对比(6.47±1.17)METs)的改善程度显著高于对照组(均P<0.05)。对于稳定型冠状动脉疾病患者,在有氧阈水平进行有氧运动联合弹力带抗阻训练是安全的。这种联合运动方案可显著提高稳定型冠状动脉疾病患者的心肺适能和运动能力。
