Evaluation Of Rhodiola Rosea Supplementation On Skeletal Muscle Damage And Inflammation In Runners Following A Competitive Marathon
Notes for this study:
||10³ cells/μl. Mean and SE. Placebo: before marathon 3.18 ± 0.07, after 13.3 ± 0.19, 1.5 h after 13.4 ± 0.17. Rhodiola: before 3.40 ± 0.10, after 12.5 ± 0.16, 1.5 h after 13.2 ± 0.15
|Number of Subjects
||18-29, 30-44, 45-64, 65+
In a randomized, double-blind, placebo-controlled trial, 55 marathon runners were allocated to take 300 mg of Rhodiola Rosea extract (11.3 mg rosavin, 4.3 mg salidroside) twice daily for 30 days prior to the marathon and 7 days after.
Funding issues for this study:
Muscle function as measured by the vertical jump test, didn't differ significantly between groups, and neither did the symptoms of DOMS. There was a nonsignificantly greater increase in creatine kinase in the Rhodiola group compared with placebo after the marathon, and there were no statistically significant differences between groups in neutrophils, lymphocytes, monocytes, AST, or ALT, as well as any cytokines or measures of inflammation, though modestly higher inflammation was found in the placebo group.
