| Effect | None |
| Values | Salivary. Mean and SD Rhodiola: before time trial 0.119 (0.057), time trial 0.214 (0.128) Placebo: before time trial 0.140 (0.054), time trial 0.239 (0.168) |
| Trial Design | Randomized trial |
| Trial Length | 24 hours |
| Number of Subjects | 18 |
| Sex | Both Genders |
In a randomized, double-blind, crossover trial, 18 recreationally active participants took 3 mg/kg of Rhodiola Rosea or placebo one hour prior to endurance testing on a bicycle ergometer.
When taking Rhodiola, participants took less time to complete the trial, which was statistically significant compared with placebo. Power output was nonsignificantly higher, while heart rate wasn't different. Lactate and salivary cortisol weren't different, while salivary alpha-amylase was higher when taking Rhodiola. When taking Rhodiola, participants noted less fatigue and confusion, but anger, vigor, depression, tension, and performance on the Stroop test weren't notably different than placebo. The rate of perceived exertion was lower when taking Rhodiola
