The Effect of Oligosaccharides in Sports Drink on Exercise Performance and Endurance Time of Athletes
並列摘要
This study aims to investigate the effect of oligosaccharides in sports drink on high-intensity exercise capacity in athletes. In our research, sixteen healthy male students of Institute of Physical Education were randomly divided into Oligosaccharide Replenishment (OR) group (n=8) and control group (n=8). Their max oxygen uptake were measured by 2900 cardiorespiratory function meter, then they all participated in a cycling test at the intensity of 80% oxygen consumption max until fatigue. The results showed that blood glucose (mmol/L) in the OR group was higher than that in the control group during exercise, the difference between the two groups was more significant along with time (5.29±1.07-6.46±0.78 and 4.71±0.84-5.36±0.80, p＜0.05). 30 min after the exercise, the change of blood lactate in the OR group was higher than that in the control group both during (6.69±1.57-7.39±1.19) and after (6.18±1.28-5.19±1.14) the exercise (p＜0.05). Cycling time [(47±12) min] and work load [(174.9±3.6) kJ] in the OR group were significantly higher than those in the control group (p＜0.05). From these results, we can see that oligosaccharide-replenishing is good for keeping blood glucose level for a long time in high-intensity exercise and prolong the time of high-intense exercise.
