Few studies have compared changes in cardiorespiratory fitness between aerobic training only or in combination with resistance training. In addition, no study to date has compared strength gains between resistance training and combined exercise training in type II diabetes mellitus (T2DM).
We evaluated the effects of aerobic exercise training (A group), resistance exercise training (R group), combined aerobic and resistance training (A + R group), and sedentary lifestyle (C group) on cardiorespiratory fitness and muscular strength in individuals with T2DM.
Two hundred and fifty-one participants in the Diabetes Aerobic and Resistance Exercise trial were randomly allocated to A, R, A + R, or C. Peak oxygen consumption (V O(2peak)), workload, and treadmill time were determined after maximal exercise testing at 0 and 6 months. Muscular strength was measured as the eight-repetition maximum on the leg press, bench press, and seated row. Responses were compared between younger (aged 39-54 yr) and older (aged 55-70 yr) adults and between sexes.
VO(2peak) improved by 1.73 and 1.93 mL O(2)*kg(-1)*min(-1) with A and A + R, respectively, compared with C (P < 0.05). Strength improvements were significant after A + R and R on the leg press (A + R: 48%, R: 65%), bench press (A + R: 38%, R: 57%), and seated row (A + R: 33%, R: 41%; P < 0.05). There was no main effect of age or sex on training performance outcomes. There was, however, a tendency for older participants to increase VO(2peak) more with A + R (+1.5 mL O(2)*kg(-1)*min(-1)) than with A only (+0.7 mL O(2)*kg(-1)*min(-1)).
Combined training did not provide additional benefits nor did it mitigate improvements in fitness in younger subjects compared with aerobic and resistance training alone. In older subjects, there was a trend to greater aerobic fitness gains with A + R versus A alone.
很少有研究比较有氧运动训练或与抗阻训练相结合对心肺功能适应性的变化。此外，迄今为止，尚无研究比较 2 型糖尿病患者（T2DM）中抗阻训练和联合运动训练的力量增益。
我们评估了有氧运动训练（A 组）、抗阻运动训练（R 组）、有氧和抗阻联合运动训练（A+R 组）和静坐生活方式（C 组）对 T2DM 患者心肺功能适应性和肌肉力量的影响。
251 名糖尿病有氧和抗阻运动试验参与者被随机分配到 A、R、A+R 或 C 组。在 0 个月和 6 个月时进行最大运动测试后，确定峰值摄氧量（V O 2peak）、工作量和跑步机时间。肌肉力量通过腿推、卧推和坐姿划船的 8 次重复最大测试来测量。结果在年轻（39-54 岁）和年长（55-70 岁）成年人以及男女之间进行比较。
与 C 组相比，A 和 A+R 分别使 V O 2peak 增加 1.73 和 1.93 mL O 2 *kg -1 *min -1（P<0.05）。A+R 和 R 使腿推（A+R：48%，R：65%）、卧推（A+R：38%，R：57%）和坐姿划船（A+R：33%，R：41%）的力量显著增加（P<0.05）。年龄或性别对训练效果没有主要影响。然而，与单独 A 训练相比，A+R 训练使年长参与者的 V O 2peak 增加更多（+1.5 mL O 2 *kg -1 *min -1），有趋势表明 A+R 比单独 A 训练更能提高有氧健身效果。
与单独的有氧和抗阻训练相比，联合训练并没有提供额外的益处，也没有改善年轻受试者的健康状况。在年长的受试者中，与单独 A 训练相比，A+R 训练在有氧健身方面有增加的趋势。
