We investigated the effect of an 8 week circuit training (CT) program, combining aerobic and resistance exercise, on indices of glycemic control, cardiorespiratory fitness, muscular strength and body composition in 16 subjects (age 52 +/- 2 years) with type 2 diabetes using a prospective randomised crossover protocol. Submaximal exercise heart rate and rate pressure product were significantly lower after training (P<0.05), whilst ventilatory threshold increased (11.8 +/- 0.7 vs 13.8 +/- 0.6 ml kg(-1)min(-1), P<0.001). Muscular strength also increased with training (403 +/- 30 to 456 +/- 31 kg, P<0.001), whilst skinfolds (148.7 +/- 11.5 vs 141.1 +/- 10.7 mm, P<0.05), % body fat (29.5 +/- 1.0 vs 28.7 +/- 1.1%, P<0.05) and waist:hip ratio (99.2 +/- 1.5 vs 97.9 +/- 1.4%, P<0.05) significantly decreased. Concurrently, peak oxygen uptake (P<0.05) and exercise test duration (P<0.001) increased following training, whilst glycated hemoglobin (P<0.05) and fasting blood glucose (P<0.05) decreased. CT is an effective method of training that improved functional capacity, lean body mass, strength and glycemic control in subjects with type 2 diabetes.
我们采用前瞻性随机交叉试验方案，研究了一项为期8周、结合有氧运动和抗阻运动的循环训练（CT）计划对16名2型糖尿病患者（年龄52±2岁）血糖控制指标、心肺适能、肌肉力量和身体成分的影响。训练后，次极量运动心率和心率血压乘积显著降低（P<0.05），同时通气阈值升高（11.8±0.7对13.8±0.6毫升·千克⁻¹·分钟⁻¹，P<0.001）。肌肉力量也随训练增加（403±30至456±31千克，P<0.001），而皮褶厚度（148.7±11.5对141.1±10.7毫米，P<0.05）、体脂百分比（29.5±1.0对28.7±1.1%，P<0.05）和腰臀比（99.2±1.5对97.9±1.4%，P<0.05）显著降低。同时，训练后峰值摄氧量（P<0.05）和运动测试持续时间（P<0.001）增加，而糖化血红蛋白（P<0.05）和空腹血糖（P<0.05）降低。循环训练是一种有效的训练方法，可改善2型糖尿病患者的功能能力、瘦体重、力量和血糖控制。
