To assess the effects of chronic supplementation with two different dosages of Panax ginseng C.A. Meyer on physiologic and psychological responses during graded maximal aerobic exercise.
Randomized, double-blind, placebo-controlled trial.
Thirty-six healthy men consuming an otherwise supplement-free diet who maintained their usual activity level.
A standardized P ginseng C.A. Meyer concentrate (G115) was added to the normal diet of study participants at a dosage level of either 200 or 400 mg/day, where 100 mg of the preparation is equivalent to 500 mg P gingseng root.
Submaximal and maximal aerobic exercise responses before and after an 8-week trial intervention.
Analysis of variance.
Thirty-one subjects completed the study. Supplementation with ginseng had no effect on the following physiologic and psychological parameters: oxygen consumption (mL/kg per minute), respiratory exchange ratio, minute ventilation (L/min), blood lactic acid concentration (mmol/L), heart rate (beats/min), and perceived exertion (P > .05).
Our data in healthy men do not offer support for claims that P ginseng C.A. Meyer is an ergogenic aid to improve submaximal and maximal aerobic exercise performance.
评估长期补充两种不同剂量的人参（Panax ginseng C.A. Meyer）对分级最大有氧运动期间生理和心理反应的影响。
随机、双盲、安慰剂对照试验。
三十六名健康男性，他们保持日常活动水平，饮食中不摄入其他补充剂。
将标准化的人参（Panax ginseng C.A. Meyer）浓缩物（G115）以每天200毫克或400毫克的剂量添加到研究参与者的正常饮食中，该制剂100毫克相当于500毫克人参根。
8周试验干预前后的次最大和最大有氧运动反应。
方差分析。
31名受试者完成了研究。补充人参对以下生理和心理参数无影响：耗氧量（毫升/千克每分钟）、呼吸交换率、分钟通气量（升/分钟）、血乳酸浓度（毫摩尔/升）、心率（次/分钟）和自觉用力程度（P>.05）。
我们在健康男性中的数据不支持人参（Panax ginseng C.A. Meyer）是一种提高次最大和最大有氧运动表现的促力剂的说法。
