本研究目的在探討枸杞多糖增補介入單次高強度運動後，對生理、生化疲勞指標之效果。方法是以中國文化大學健康男性大學生11名為研究對象，平均年齡 20.9 ± 2.38 歲，身高174.3 ± 9.23 公分，體重為78.0 ± 23.93 公斤。每位受試者需進行二次 75% VO2 max之運動強度於原地跑步機上持續運動45分鐘。隨機分成兩組，且於運動前分別接受持續增補七天枸杞多糖與安慰劑增補方式，並於運動中測量其攝氧量，於跑步結束0、30、60分鐘測血壓與心跳率。運動前，運動後立即與次日採血來分析各項血液生化值 (BUN、LDH、CK、AST)。所得資料以重覆量數二因子變異數分析，以α=.05為顯著水準。結果顯示在安慰劑組血尿素氮 (BUN：15.72±3.71 mg/dl) 與乳酸脫氫酶 (LDH：695.36±121.77 U/L) 運動後平均值在統計上顯著高於運動前 (p<.05)，其餘枸杞多糖組平均值皆低於安慰劑組，但在統計上並無組間差意存在 (p>.05)。本研究結論出，增補枸杞多糖對高強度運動後疲勞恢復並無顯著提升之影響。
Purpose: The purpose of this study was to investigate the effect of lycium barbarum polysaccharides supplementations with a single high-intensity exercise on fatigue recovery. Method: Eleven healthy male college students of Chinese Culture University participated as subjects (age: 20.9 ± 2.38 yrs, height: 174.3 ± 9.23 cm, 78.0 ± 23.93 kg). Each of the subjects engaged in two bouts of running on treadmill with the intensity of 75% VO2max for 45 minutes. Randomly divided into two groups and before exercise continued seven days with placebo and lycium barbarum polysaccharides supplement, 75% VO2max was measured during exercise. Measuring blood pressure and heart rate 0,30,60 minutes at the end of the running, Blood samples collected at immediately, before, after exercise and the next morning. Data were analyzed by using two-way ANOVA (α=.05). Result: Placebo (BUN: 15.72 ± 3.71 mg/dl) and (LDH: 695.36 ± 121.77 U/L) after exercise were statistically significantly higher than the average pre-exercise (p<.05), the average of the rest of lycium barbarum polysaccharides group were lower than in the placebo group, but no statistically significant difference between the groups (p>.05). Conclusion: Effects of lycium barbarum polysaccharides supplements did not significantly improve the recovery of high-intensity exercise fatigue.
