Abstract

OBJECTIVE

We examined the effects of Applephenon and ascorbic acid administration on physical fatigue.

METHODS

In a double-blinded, placebo-controlled, three-way crossover design, 18 healthy volunteers were randomized to oral Applephenon (1200 mg/d), ascorbic acid (1000 mg/d), or placebo for 8 d. The fatigue-inducing physical task consisted of workload trials on a bicycle ergometer at fixed workloads for 2 h on two occasions. During the test, subjects performed non-workload trials with maximum velocity for 10 s at 30 min (30-min trial) after the start of the test and 30 min before the end of the test (210-min trial).

RESULTS

The change in maximum velocity between the 30- and 210-min trials was higher in the group given Applephenon than in the group given placebo; ascorbic acid had no effect.

CONCLUSION

These results suggest that Applephenon attenuates physical fatigue, whereas ascorbic acid does not.

摘要

目的

我们研究了给予苹果多酚和抗坏血酸对身体疲劳的影响。

方法

采用双盲、安慰剂对照、三向交叉设计，将18名健康志愿者随机分为口服苹果多酚（1200毫克/天）、抗坏血酸（1000毫克/天）或安慰剂组，每组服用8天。诱发疲劳的身体任务包括在自行车测力计上以固定工作量进行两次2小时的工作量试验。在测试过程中，受试者在测试开始后30分钟（30分钟试验）和测试结束前30分钟（210分钟试验）以最大速度进行10秒非工作量试验。
