The purpose of this study was to compare the effect of aquatic treadmill exercise (ATM) to land treadmill exercise (LTM) in adults with and without type 2 diabetes (T2D).
Five participants with T2D (4 females, 1 male; age=51±3 years; height=170±3 cm; weight=96±11 kg; body fat=32±1%) and five participants without T2D (4 females, 1 male; age=51±3 years; height=170±3 cm; weight=71±15 kg; body fat=27±2%) completed the study. Participants completed three, 5-minute stages of exercise at 3.2 km/h, 4.8 km/h and 6.4 km/h with 0% grade on land and aquatic treadmills. Heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), absolute and relative oxygen consumption (VO2), and energy expenditure were measured at rest and during steady-state exercise at each intensity. A 2x2x4 Mixed Factorial ANOVA and Bonferroni post-hoc test with a significance level of 0.05 was used.
All variables increased as speed increased (P<0.05) independent of group or mode. The HR value was higher on the LTM versus the ATM independent of group and treadmill stage (P=0.002) and SBP was higher in the T2D group versus no T2D independent of treadmill mode and stage (P=0.01). Relative VO2 was higher in the group without T2D compared to the T2D group at 6.4 km/h independent of treadmill mode (P=0.032).
Although there is some evidence for the varying effects of aquatic and land exercise when comparing those with and without T2D, cardiorespiratory and metabolic variables are similar in both groups during locomotion on land and in an aquatic environment.
本研究旨在比较水上跑步机运动（ATM）与陆地跑步机运动（LTM）对患有和未患有2型糖尿病（T2D）的成年人的影响。
五名患有T2D的参与者（4名女性，1名男性；年龄=51±3岁；身高=170±3厘米；体重=96±11千克；体脂=32±1%）和五名未患有T2D的参与者（4名女性，1名男性；年龄=51±3岁；身高=170±3厘米；体重=71±15千克；体脂=27±2%）完成了本研究。参与者在陆地和水上跑步机上以3.2公里/小时、4.8公里/小时和6.4公里/小时的速度，坡度为0%，完成三个5分钟阶段的运动。在休息时以及每个强度的稳态运动期间，测量心率（HR）、收缩压和舒张压（SBP和DBP）、绝对和相对耗氧量（VO2）以及能量消耗。使用显著性水平为0.05的2×2×4混合因子方差分析和Bonferroni事后检验。
所有变量均随速度增加而增加（P<0.05），与组别或运动模式无关。无论组别和跑步机阶段如何，LTM上的HR值均高于ATM（P=0.002），且无论跑步机模式和阶段如何，T2D组的SBP均高于无T2D组（P=0.01）。在6.4公里/小时的速度下，无论跑步机模式如何，未患有T2D的组的相对VO2均高于患有T2D的组（P=0.032）。
尽管在比较患有和未患有T2D的人群时，有一些证据表明水上和陆地运动的效果存在差异，但在陆地和水环境中运动时，两组的心肺和代谢变量相似。
