Skeletal muscle, liver and heart glycogen variations, induced by swimming in thermal water (at 35 degrees C) as a model of physical exercise for clinical use, were studied. Muscle and liver glycogen moderately decreases after a 30-min period of swimming and comes near to depletion after 60 min. Heart glycogen decreases only slightly after 60 min. Blood glucose and plasma insulin decrease only after 60 min of swimming. A 30-min swim in thermal water, cooled to 25 degrees C, depletes muscle and liver glycogen and slightly decreases heart glycogen. Under these conditions, plasma insulin decreases and hypoglycemia occurs. The results seem to indicate some advantages of swimming in hot thermal water in order to prevent glycogen store depletion as the physiological prerequisite for a physical exercise of clinical interest to obtain therapeutical benefits, avoiding premature fatigue and exhaustion.
研究了在35摄氏度热水中游泳作为临床使用的体育锻炼模型所引起的骨骼肌、肝脏和心脏糖原变化。游泳30分钟后，肌肉和肝脏糖原适度减少，60分钟后接近耗尽。60分钟后心脏糖原仅略有减少。游泳60分钟后血糖和血浆胰岛素才降低。在冷却至25摄氏度的热水中游泳30分钟会耗尽肌肉和肝脏糖原，并使心脏糖原略有减少。在这些条件下，血浆胰岛素降低并发生低血糖。结果似乎表明，在热的热水中游泳具有一些优势，可防止糖原储备耗尽，这是进行具有临床意义的体育锻炼以获得治疗益处、避免过早疲劳和疲惫的生理前提。
