The aim of this study was to examine the influence of water immersion to the chest on cardio-vascular adaptation to exercise. Upright or sitting immersion causes an increase in central blood volume, but it remains controversial whether central blood volume remains elevated during dynamic exercise in water and facilitates cardiac adaptation, depending particularly on the intensity of exercise which can be matched for O2 consumption (metabolic range) or for mechanical intensity (work load). We have compared hemodynamic variables measured during two cycling exercises at the same mechanical intensity, performed both in ambiant air and during immersion up to the chest.
本研究的目的是探讨胸部水浸对心血管运动适应性的影响。直立或坐姿水浸会导致中心血容量增加,但在水中进行动态运动时中心血容量是否仍保持升高并促进心脏适应仍存在争议,这尤其取决于可与耗氧量(代谢范围)或机械强度(工作负荷)相匹配的运动强度。我们比较了在相同机械强度下进行的两次自行车运动期间测量的血流动力学变量,这两次运动分别在环境空气中和胸部水浸期间进行。
