The Effect of Acute Rhodiola rosea Ingestion on Exercise Heart Rate, Substrate Utilisation, Mood State, and Perceptions of Exertion, Arousal, and Pleasure/Displeasure in Active Men.

Duncan MJ, Clarke ND - J Sports Med (Hindawi Publ Corp) (2014)

Bottom Line: Perceptions of arousal (P = 0.05) and pleasure were significantly higher after exercise with R. rosea compared to placebo (P = 0.003).Mood state scores for vigor were also higher in R. rosea condition compared to placebo (P = 0.008).There were no significant differences in energy expenditure, carbohydrate, or fat oxidation between conditions (P > 0.05).

ABSTRACT
The aim of this study was to examine the effect of acute Rhodiola rosea (R. rosea) ingestion on substrate utilisation, mood state, RPE, and exercise affect. Ten males (mean age ± S.D. = 26 ± 6 years) completed two 30-minute cycling trials at an intensity of 70% of [Formula: see text] following ingestion of either 3 mg·kg(-1) body mass of R. rosea or placebo using a double-blind, crossover design. During exercise, heart rate and RPE were recorded. Participants completed measures of mood state and exercise affect before and after exercise. Expired air samples were taken during exercise to determine substrate utilisation. Repeated measures analysis of variance indicated that RPE was significantly lower at 30 minutes into exercise versus placebo (P = 0.003). Perceptions of arousal (P = 0.05) and pleasure were significantly higher after exercise with R. rosea compared to placebo (P = 0.003). Mood state scores for vigor were also higher in R. rosea condition compared to placebo (P = 0.008). There were no significant differences in energy expenditure, carbohydrate, or fat oxidation between conditions (P > 0.05). Ingestion of R. rosea favourably influenced RPE and exercise affect without changes in energy expenditure or substrate utilization during 30-minute submaximal cycling performance.

Mentions: In the case of RPE, results indicated a significant substance × time interaction (F 3, 27 = 6.12, P = 0.003, Pη2 = 0.405, see Figure 1). RPE data were not significantly different at rest and at 10 and 20 minutes into the exercise bout between the two conditions. However, RPE in the placebo condition was significantly higher than that in the R. rosea condition 30 minutes into the exercise bout (P = 0.003).
