Cordyceps sinensis (=Ophiocordyceps sinensis) and Ganoderma lucidum are 2 medicinal mushrooms that have been suggested to have the potential to enhance exercise capacity. We used a commercial supplement combining a traditional Chinese medicine and G. lucidum and tested its effects on human physical, aerobic, and anaerobic capacities. Physical education students (n = 96; 43 women, 53 men; mean ± standard deviation age, 26.3 ± 3.21 years) were randomly divided into 3 groups: low-dose treatment, high-dose treatment, and placebo. Participants received the supplement or the placebo for 28-33 days. Both before and after the intervention, the participants performed a graded maximum oxygen consumption (Vo2max) test on a treadmill and a Wingate anaerobic cycle test (on a different day). The following parameters were measured and recorded during the maximal graded treadmill test: heart rate, oxygen consumption, respiratory exchange ratio, and ventilation. The following parameters were calculated from the Wingate anaerobic cycle test: maximal anaerobic power, mean anaerobic power, and fatigue index. The supplements did not affect Vo2max or the physiological responses upon maximal exercise during the graded treadmill test. In a similar way, they had no effect on peak or mean power, or fatigue index, as measured by the Wingate anaerobic test. A borderline interaction indicated a somewhat lower heart rate at rest after treatment; however, post hoc analysis did not reveal any further statistically significant differences (P = 0.047; F = 3.169). The findings indicate that dual supplementation with C. sinensis and G. lucidum had no effect on Vo2max, on physiological responses at peak exercise load during a graded maximal treadmill test, or on the parameters of anaerobic capacity.
冬虫夏草（=中华束丝孢）和灵芝是两种药用真菌，有人认为它们具有提高运动能力的潜力。我们使用了一种将中药与灵芝相结合的商业补充剂，并测试了其对人体体能、有氧和无氧能力的影响。体育专业学生（n = 96；43名女性，53名男性；平均±标准差年龄，26.3±3.21岁）被随机分为3组：低剂量治疗组、高剂量治疗组和安慰剂组。参与者接受补充剂或安慰剂28 - 33天。在干预前后，参与者在跑步机上进行了分级最大耗氧量（Vo2max）测试，并在不同日期进行了温盖特无氧自行车测试。在最大分级跑步机测试期间测量并记录了以下参数：心率、耗氧量、呼吸交换率和通气量。从温盖特无氧自行车测试中计算出以下参数：最大无氧功率、平均无氧功率和疲劳指数。补充剂对分级跑步机测试期间的Vo2max或最大运动时的生理反应没有影响。同样，它们对通过温盖特无氧测试测量的峰值或平均功率以及疲劳指数也没有影响。一个临界交互作用表明治疗后静息心率略低；然而，事后分析未发现任何进一步的统计学显著差异（P = 0.047；F = 3.169）。研究结果表明，冬虫夏草和灵芝联合补充剂对Vo2max、分级最大跑步机测试期间峰值运动负荷时的生理反应或无氧能力参数没有影响。
