目的：探討不同訓練環境 (室內、戶外) 青少年籃球選手之皮膚含水量與皮膚彈性的差異性。方法：將28 名高中三年級籃球選手以立意取樣方式，分為室內訓練環境與戶外訓練環境2 組，每組各14 人，在室溫20-24℃，溼度50-60％的室內環境進行皮膚檢測。本研究採用儀器為德國製多功能皮膚檢測系統(Gutometer MPA580) 中之皮膚水分測定探頭 (Corneometer CM825)，來測定皮膚含水量；以皮膚彈性測定探頭 (Cutometer MPA580 內建Viscoelasticity)，來測定皮膚彈性。本研究統計方式以獨立樣本t-test，顯著水準訂為α=.05。結果：在不同訓練環境中，高中籃球選手之皮膚含水量並未達顯著；而皮膚彈性上有顯著差異。綜合上述，本研究之結論：高中籃球選手在不同訓練環境中，皮膚含水量並無顯著的差異，但皮膚彈性上有顯著差異。

Skin isolates human body from external environment and protects us from harm. The essential factors of making skin work well are skin surface hydration, skin elasticity, transepidermal water loss and row of perspiration quantity. Skin is easy to expose to UV and injured when doing exercise training. Over a long period of time, UV will cause sunburn and even skin cancer. As so far, there are few studies of high school player's skin protection. To prevent high school players in different training space from injuring by exposure too much UV, The purpose of the research was to examine the difference of high school basketball players' skin water content and skin elasticity in different training space (outdoor and indoor) . The subjects of this research selected 14 high school basketball players training indoor and 14 high school basketball players training outdoor. The instrument we used was Corneometer CM825 (Gutometer MPA580). The data was analyzed by independent t test (α=.05). Result: The skin water content did not make much difference of high school basketball players, but it made obviously contrast of skin elasticity in different training environment. To tell from above, the conclusions of this study were as followed: In different training environment, the skin water content of the high school basketball players had no notable difference. The skin elasticity, had a significant difference between high school basketball players in different training environment.
