ABSTRACT
Cordyceps militaris has been used extensively as a crude drug and a folk tonic food in East Asia due to its various pharmacological activities. Our study aims to investigate the effect of Cordyceps militaris fruit body extract (CM) on antifatigue in mouse model. Two week CM administration significantly delayed fatigue phenomenon which is confirmed via rotating rod test, forced swimming test and forced running test. Compared to nontreated mouse, CM administration increased ATP levels and antioxidative enzymes activity and reduced the levels of lactic acid, lactic dehydrogenase, malondialdehyde, and reactive oxygen species. Further data suggests that CM-induced fatigue recovery is mainly through activating 5'-AMP-activated protein kinase (AMPK) and protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathways and regulating serum hormone level. Moreover, CM-enhanced the phosphorylation of AMPK contributes to its antioxidant effect. Our data provides experimental evidence in supporting clinical use of CM as an effective agent against fatigue.

Treatment with Cordyceps militaris fruit body extract (0.5 g/kg, 1.0 g/kg, and 2.0 g/kg) and Rhodiola rosea (0.5 g/kg) for 2 weeks, before and after 20 min swimming, the levels of lactic acid in serum ((a), (b)), liver ((c), (d)), and muscle ((e), (f)) in male and female mouse were analyzed, respectively. Data are expressed as mean ± S.D. (n = 6) and analyzed using one-way ANOVA followed by Dunn's test. ∗P < 0.05 and ∗∗P < 0.01 versus nontreated mouse (Control).

Mentions: The accumulation of lactate interferes with nerve impulses and muscle contraction, thus resulting in fatigue [21]. Before swimming, no significant differences on LD levels in serum, liver, and muscle were noted in female and male mice among all groups except for in muscle tissue of male mouse (Figure 2). After 20 min exercise, compared with nontreated mouse, 17.0%, 18.7%, and 36.6% reduction on LD level in serum, liver, and muscle were observed in 2.0 g/kg CM treated female mouse, respectively (P < 0.05; Figures 2(a), 2(b), and 2(c)). Interestingly, in male mouse, CM at dose of 1.0 g/kg only reduced 17.0% and 38.9% LD level in serum and muscle (P < 0.05; Figures 2(d) and 2(f)). Rhodiola rosea showed reductive effect on LD level only in serum and liver of female mouse (P < 0.05; Figures 2(a) and 2(b)).
