To compare the acute effects of aquatic walking/running versus dry-land walking/running on blood glucose and plasma renin activity (PRA) in individuals with type 2 diabetes, participants with type 2 diabetes performed deep-water or dry-land walking and/or running sessions in a swimming pool or on an athletics track, respectively. Both sessions comprised seven blocks of 3 min at 85-90% of the heart rate deflection point (HRDP), interspersed with 2 min at <85% HRDP, totaling 35 min, with a 48 h interval between sessions. PRA and blood glucose were assessed before and immediately after the sessions. Generalized estimation equations were used to verify the session effects, with the Bonferroni post hoc test, considering the significance level as 0.05. Twelve individuals (53.2 ± 8.9 years) diagnosed with type 2 diabetes for 6.3 ± 6.34 years participated in the study. A reduction in PRA was found only after the aquatic session (-7.75 ng/mL/h; -69%; : 0.034), while both aquatic and dry-land sessions similarly reduced the blood glucose levels (aquatic: -38 mg/dL, -21%; dry-land: -26 mg/dL, -14%; time effect, = 0.007). Despite yielding similar glycemic reductions as dry-land walking/running, aquatic walking/running led to an expressive decrease in PRA among individuals with type 2 diabetes.
为了比较水疗步行/跑步与旱地步行/跑步对 2 型糖尿病患者血糖和血浆肾素活性（PRA）的急性影响，2 型糖尿病患者分别在游泳池或田径场上进行深水区或旱地步行和/或跑步训练。两个训练课程均由 7 个 3 分钟的时间段组成，强度为心率偏移点（HRDP）的 85-90%，间隔 2 分钟，强度<85% HRDP，总共 35 分钟，两次训练课程之间间隔 48 小时。在训练前后评估 PRA 和血糖。使用广义估计方程验证课程效果，采用 Bonferroni 事后检验，考虑到显著性水平为 0.05。12 名（53.2±8.9 岁）患有 2 型糖尿病且患病时间为 6.3±6.34 年的患者参加了该研究。仅在水疗课程后发现 PRA 降低（-7.75ng/mL/h；-69%；：0.034），而水疗和旱地课程均可降低血糖水平（水疗：-38mg/dL，-21%；旱地：-26mg/dL，-14%；时间效应，=0.007）。尽管水疗步行/跑步与旱地步行/跑步产生相似的降血糖效果，但它可使 2 型糖尿病患者的 PRA 明显降低。
