Rhodiola Crenulata and Cordyceps Sinensis based supplementation enhance the aerobic exercise performance after two weeks of altitude training.

This study examined the effect of a novel supplement consisting of Rhodiola Crenulata and Cordyceps Sinensis on aerobic exercise capacity after four weeks of altitude training. Alterations of autonomic nervous system function and circulatory-hormonal and haematological profiles were investigated. An RC (Rhodiola Crenulata and Cordyceps Sinensis) group and placebo group were compared.
After four weeks of altitude training, running time to exhaustion improved and parasympathetic activity was higher in the RC group when compared to the placebo group. Red blood cell count, and hematocrit and hemoglobin levels were elevated in both groups to a similar extent after altitude training. The erythropoietin level in the RC group was lower than in the placebo group after training/adaptation.
Implication. Rhodiola Crenulata and Cordyceps Sinensis supplementation during altitude training exhibited a greater training benefit in improving aerobic performance than in a non-RC placebo treatment.
