The effect of an underwater environment on cardiac autonomic nervous activity and to reduce progress towards diabetic nephropathy for diabetes patients.

本研究的目的是明确水下环境对2型糖尿病患者坐臂摇臂运动时心脏副交感神经活动和尿白蛋白排泄（UAE）的影响。水中运动20分钟后的双乘积显著低于陆上运动。水中运动后的UAE水平比陆上运动后的UAE水平有降低的趋势。水中摇臂运动3个月后，心脏副交感神经活动增加，运动后UAE降低。提示水中坐臂摇臂运动是2型糖尿病患者安全、有益的运动。

The purpose of this study is to make clear that the effect of an underwater environment on cardiac parasympathetic nervous activity and urinary albumin excretion (UAE) during in sitting arm cranking exercise for type 2 diabetes patients. Double product shortly after 20 minute’s exercise in water showed significant lower than that of on land. UAE after exercise in water demonstrated a tendency to lower level than that of on land. Arm cranking exercise in water for 3 months effected on cardiac parasympathetic nervous activity increased and UAE after exercise decreased. It is suggested that arm cranking exercise on sitting in water could be safety and beneficial exercise for type 2 diabetes patients.
