Chen, C-Y., Lin, C-H., Liao, Y-H., Hung, T-C., Hou, C-W., Chen, C-C., & Cheng, L-L. (2013). Rhodiola crenulata and Cordyceps sinensis based supplementation enhance the aerobic exercise performance after two weeks of altitude training. Medicine & Science in Sports & Exercise, 45(5), Supplement abstract number 2404.
This study examined the effect of a novel supplement consisting of Rhodiola crenulata and Cordyceps sinensis on aerobic exercise capacity during four weeks of altitude training. The alterations of autonomic nervous system and circulatory hormonal and hematological profiles were investigated. A supplemented and placebo (non-supplemented) group trained for four weeks.
Running time to exhaustion and parasympathetic activity were higher in the supplemented group. Red blood cell, hematocrit, and hemoglobin levels were elevated in both groups to a comparable extent after the altitude training, whereas the erythropoietin level in the supplemented group was lower than in the placebo group.
Implication. Rhodiola crenulata and Cordyceps sinensis supplementation during altitude training is associated with an improved training benefit for aerobic performance.
