摘要

本研究主要是利用不同水溫從事相同的游泳訓練，觀察水溫的不同是否會對肌肉肝醣儲存量有肝醣超載加成的效果。本實驗設計將SD老鼠分為三組，控制組(n=8)、34℃溫水運動組(n=8)及25℃冷水運動組(n=8)。運動訓練介入以游泳方式連續實施兩週，每週七天，游泳訓練時間為兩小時。在運動介入結束後，為觀察肌肉肝醣儲存量，立即以胃管補充每公斤體重2公克的葡萄糖（濃度50%W/V），並於休息恢復後16小時立即活體手術取腓腸紅白肌、股四頭紅白肌、蹠肌、比目魚肌及心肌等肌肉。分析結果發現，冷水運動組及溫水運動組腓腸紅肌、白肌的肝醣儲存量明顯高於控制組，另外，冷水運動組腓腸紅白肌的肝醣儲存量又明顯高於溫水運動組。腓腸紅白肌的GLUT4蛋白表現量為兩組運動組明顯高於控制組，但兩組運動組並沒有差異。結論，本研究發現在水溫25℃進行游泳訓練會有肝醣超載加成的效果。

This study investigated the effects of swimming training in different water temperatures on muscle GLUT4 protein expression and glycogen storage. Twenty-four female SD rats were weight-matched into three groups, including the control group (C), the 34℃ water temperature training group (W), and the 25℃ water temperature training group (CO). After two weeks of swimming training, the muscle GLUT4 protein gene expression, glycogen storage, and whole body glucose tolerance were measured. Our results showed that the glycogen content of red and white quadriceps muscles in CO and W groups were significantly higher than those of the control group. Meanwhile, the glycogen content of the red and white gastrocenimus muscles also revealed the consistent pattern as quadriceps muscles. Moreover, the GLUT4 protein expression of red and white gastrocenimus muscles in both warm-and cold-temperature exercise training groups were significantly higher than those in the control group. In conclusion, we found that swimming training in 25℃ water significantly enhanced glycogen storage but not the alteration in muscle GLUT4 protein expression.
