液體攝取方案對女子足球員訓練後的血糖與運動強度自覺之影響

Effect of Fluid Ingestion Protocol on the Blood Sugar and Ratings of Perceived Exertion after Training in Female Soccer Players

目的：研究旨在探討女子足球員在訓練期間接受液體攝取方案對其血糖與運動強度自覺的影響。方法：18位女子足球員（年齡：20.6±1.6歲、身高：162.6±5.6公分、體重：56.71±5.04公斤、球齡：10.7±2.5年），分為攝取飲用水（W組）與攝取運動飲料（CE組），在舒適環境下進行90分鐘的足球訓練比賽，期間在預定的時間點攝取液體，W組與CE組的攝取量，分別為1259.33±95.42毫升與1234.11±116.35毫升。訓練前後皆進行血糖及運動強度自覺之測量。結果：兩組間訓練後的血糖，W組91.67±9.07毫克/分升，顯著低於CE組129.78±18.47毫克/分升；兩組間訓練後的運動強度自覺無顯著差異，但W組的運動強度自覺，訓練後3.56±1.33顯著高於訓練前1.11±1.36。結論：液體攝取方案中，攝取運動飲料較有益於訓練期間的血糖維持與提高，若只攝取飲用水，訓練後的運動強度自覺會高於訓練前。

Purpose: To investigate the effect of fluid ingestion protocol on blood sugar and ratings of perceived exertion in female soccer players during the training. Methods: 18 female soccer players (age: 20.6 ± 1.6 year-old, height: 162.6 ± 5.6 cm, weight: 56.71 ± 5.04 kg, years of playing soccer: 10.7 ± 2.5 years), were divided into two groups. One group drank water (W group) while other group drank sport drinks (CE group). For 90 minutes training under comfortable environment, test subjects were given liquid at designed time during training. The liquid supplement of W and CE were 1259.33 ± 95.42 ml and 1234.11 ± 116.35 ml. Blood sugar concentration and ratings of perceived exertion were measured before and after training. Results: The study indicated that the blood sugar level of W was 91.67 ± 9.07 mg/dl which is significantly lower than 129.78 ± 18.47 mg/dl of CE; and there were no significant changes between W and CE in the ratings of perceived exertion after the training, though the ratings of perceived exertion after training of W was 3.56 ± 1.33 significantly higher than before training at 1.11 ± 1.36. Conclusion: Thus, in summary, sport drinks are better at maintaining the blood sugar concentration during training, but only consuming water will result in an increase of rated perceived exertion after training.
