本研究目的在探討手部運動對血糖變化之影響，並建立運動強度和時間對血糖變化之預測模式。本研究共收集33位符合條件之第2型糖尿病患者，每位個案均接受手部運動測試，根據測試結果分別依不同運動強度 (40%、60%、80%最大工作負荷量) 和不同運動時間 (10、20、30、40分) 設定12次手部運動，在每次運動前後皆測量血糖變化。研究結果顯示，在每次運動後血糖均顯著下降。但運動強度和運動時間對血糖變化之影響並無交互作用，只有運動時間對血糖變化之影響有顯著意義 (F = 11.756，p < .0001)。同時運動時間是手部運動對血糖變化反應最重要的因素。本研究結果支持手部運動對第2型糖尿病患者的血糖控制扮有重要的角色。

　　　　　The aims of the study were to examine the influence of upper extremity exercise on glucose response and to establish a predictive model of changes in serum glucose under different exercise intensities and durations. Thirty-three type 2 DM patients who met the selection criteria were selected. An arm cycle ergometer exercise test was conducted, and then 12 arm exercise sessions were arranged based on different exercise intensities (40%, 60%, and 80% of maximal workload) and exercise durations (10, 20, 30, and 40 min). Serum glucose levels were measured before and after each exercise session. Serum glucose levels significantly decreased after arm exercise regardless of different intensities or durations. However, no interaction effect (intensity �e duration) or main effect in exercise intensity was observed, but a significant main effect in exercise duration was observed (F = 11.756, p < .0001). Also exercise duration was a significant predictor of serum glucose changes after arm exercise. These results suggest that arm exercise can play a useful role in glycemic control for type 2 DM patients and exercise duration is a key factor in determining serum glucose response under upper-extremity exercise.
