VAS法で測定した快適感, リラックス感, 体のすっきり感の自覚的体感は入浴中, 入浴終了2時間後ともにそれぞれ有意な改善が認められた. 【総括】ラジウム温泉浴が及ぼす生理的作用について, 上腕動脈血管内皮機能の検査を組み入れて評価した結果, 入浴中および入浴後の血流依存性血管拡張反応率 (FMD%) と血管拡張径を増加させる効果があることを見出し, かつ血圧の低下や自覚的体感も向上させる利点もあることを明らかにした., Effects of radium hot spring bathing on flow-mediated dilation, physiologic values, and subjective feeling were investigated in healthy adults. Sixteen adults (8 men and 8 women) were subjected to bathing for 20 min and staying in rest until 2 h postbathing. During the period of bathing and postbathing, effects on brachial artery flow-mediated dilation (FMD and vascular diameter), physiologic values, and subjective feeling were measured and analyzed. Average values of FMD and vascular diameter, 7.5±0.8% and 0.27±0.03mm, before bathing increased significantly to 9.3±1.0% and 0.35±0.03mm during 20 min bathing and then these significant increases were sustained for 2 h after bathing, respectively. Subgroup analysis of these changes for men and women revealed that significant increases after bathing were sustained only in a women’s group. The average values of systolic and diastolic blood pressures, body weights, and body fat percentages decreased significantly during bathing and after bathing in comparison with those before bathing, but pulse rates and body temperatures increased significantly only during bathing. Subjective feelings containing cheerfulness, relaxation, and physical activity were measured using visual analog scale (VAS) and improvement of them was observed during and after bathing. These results indicate that radium hot spring bathing exerted beneficial effects in increase of flow-mediated dilation, decrease of blood pressure, and improvement of subjective feelings.}, pages = {217--226}, title = {ラジウム温泉浴が健常成人の血管内皮機能, 生理学的検査値および自覚的体感に及ぼす影響}, volume = {126}, year = {2012} }
