To investigate the effects of 8 wk of upright water-based exercise training in people with type 2 diabetes.
Thirteen participants with type 2 diabetes (54% male; 60.9 ± 9.6 yr, mean ± standard deviation) completed 8 wk of upright water-based exercise training at a moderate intensity (60%-80% of exercise test-derived maximum HR), for 1 h, three times a week (TG). Fourteen participants (64% male; 63.9 ± 9.8 yr) acted as a control group (CG) who maintained their usual activities. Preintervention and postintervention, participants performed cardiopulmonary exercise testing to determine V˙O2peak and one-repetition maximum testing to assess muscular strength. Blood profiles were assessed with standard assays. Body mass index and waist/hip ratio were employed as measures of anthropometry. Endothelium-dependent (brachial artery flow-mediated dilation) and independent (glyceryl trinitrate-mediated) function were assessed using vascular ultrasound.
Water-based training increased V˙O2peak (18.5 ± 4.3 mL·kg·min to 21.5 ± 5.4 mL·kg·min) (P = 0.002), overall muscle strength (123 ± 44 kg to 139 ± 43 kg) and leg strength (92 ± 28 kg to 104 ± 29 kg), compared with the CG (P = 0.001). The effect on pectoral strength (31 ± 17 kg to 35 ± 16 kg) was not significantly different to the CG (24 ± 12 kg to 26 ± 14 kg) (P = 0.08). No change was observed in anthropometry, blood profiles, or glyceryl trinitrate-mediated vascular function. Flow-mediated dilation was increased after training (6.1% ± 2.4% to 6.5% ± 3.0%), compared with controls who demonstrated a slight decrease (6.2% ± 1.6% to 5.4% ± 1.6%) (P = 0.002).
Water-based circuit training was well tolerated and appears to be an effective exercise modality for improving aerobic fitness, strength, and vascular function in people with type 2 diabetes.
研究 8 周直立水基运动训练对 2 型糖尿病患者的影响。
13 名 2 型糖尿病患者（54%为男性；60.9±9.6 岁，均值±标准差）完成 8 周的直立水基运动训练，强度适中（运动试验得出的最大心率的 60%-80%），每周 3 次，每次 1 小时（TG 组）。14 名参与者（64%为男性；63.9±9.8 岁）作为对照组（CG 组），保持他们的日常活动。在干预前和干预后，参与者进行心肺运动测试以确定 V˙O2peak，进行一次重复最大测试以评估肌肉力量。采用标准测定法评估血液谱。体重指数和腰臀比用于人体测量。采用血管超声评估内皮依赖性（肱动脉血流介导的扩张）和独立（硝化甘油介导）功能。
水基训练使 V˙O2peak（18.5±4.3mL·kg·min 增加到 21.5±5.4mL·kg·min）（P=0.002）、整体肌肉力量（123±44kg 增加到 139±43kg）和腿部力量（92±28kg 增加到 104±29kg）均得到提高，与 CG 组相比（P=0.001）。与 CG 组相比（31±17kg 增加到 35±16kg）（P=0.08），对胸肌力量（24±12kg 增加到 26±14kg）的影响无明显差异。人体测量、血液谱或硝化甘油介导的血管功能均未发生变化。与对照组相比，血流介导的扩张在训练后增加（6.1%±2.4%增加到 6.5%±3.0%）（P=0.002）。
水基循环训练耐受性良好，似乎是改善 2 型糖尿病患者有氧适能、力量和血管功能的有效运动方式。
