To determine the short term effects (21 days) of 200 mg (7% standardized) Panax ginseng supplementation vs. placebo on peak aerobic exercise performance in healthy young adults, with unrestricted diets.
Twenty men and eight women (age = 23.2 +/- 3.2 years, height = 175.8 +/- 8.6 cm; weight = 75.2 +/- 15.3 kg) were randomly assigned to either a Panax ginseng or placebo group for a period of 3 weeks in a double blind design. Prior to and following treatment the subjects performed a symptom limited graded exercise test on a Schwinn Airdyne ergometer. The data were analyzed using an analysis of variance.
No significant treatment effect was observed for the dependent variables of VO2, exercise time, workload, plasma lactate and hematocrit at peak levels, or for heart rate and rate of perceived exertion at 150 watts, 200 watts and peak.
The results of this study do not support an ergogenic effect on peak aerobic exercise performance following a 3-week supplementation period of 200 mg 7% Panax ginseng in healthy young adults with moderate exercise capacities and unrestricted diets.
确定在饮食不受限制的健康年轻成年人中，补充200毫克（7%标准化）人参相较于安慰剂对有氧锻炼峰值表现的短期影响（21天）。
20名男性和8名女性（年龄=23.2±3.2岁，身高=175.8±8.6厘米；体重=75.2±15.3千克）以双盲设计被随机分配到人参组或安慰剂组，为期3周。在治疗前后，受试者在施温空气阻力测力计上进行了症状受限的分级运动测试。数据采用方差分析进行分析。
在峰值水平下，对于摄氧量、运动时间、工作量、血浆乳酸和血细胞比容等因变量，以及在150瓦、200瓦和峰值时的心率和主观用力程度，均未观察到显著的治疗效果。
本研究结果不支持在有中等运动能力且饮食不受限制的健康年轻成年人中，补充200毫克7%人参3周后对有氧锻炼峰值表现有促力作用。
