Evaluation of the Therapeutic of the Standardized Dry Extract of Rhodiola rosea in Physical Activity Practiotioners

Abstract

Aims: To evaluate the effects of Rhodiola rosea supplementation on physical performance, glycemic levels, and cardiovascular parameters in a clinical trial. Study Design: Randomized crossover clinical trial. Methodology: Twenty-five participants (12 females and 13 males) were randomly divided into two groups. Each group received starch treatment and dry extract of R. rosea at different times, with an interval period between the treatments. Weight, systolic and diastolic blood pressure, heart rate, glycemic levels, and perceived effort (assessed by the Borg scale) were measured at baseline and the end of each treatment phase. Lactate levels were also evaluated. Statistical analyses compared intra- and intergroup variations, considering p<0.05 as significant. Results: Analyses revealed no significant changes in weight, systolic and diastolic blood pressure, heart rate, or glycemic levels within or between groups. Perceived effort did not differ significantly between treatments. However, a significant variation in lactate levels was observed. Conclusion: Supplementation with R. rosea may offer potential benefits for endurance and stamina in sports activities, although further studies are needed to confirm its efficacy.
