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: Energy expenditure was significantly higher during exercise (F 2, 18 = 130.921, P < 0.001, Pη2 = 0.936) (see Figure 3), irrespective of the trial (F 1, 9 = 1.198, P = 0.302, Pη2 = 0.117). The rate of total carbohydrate oxidation (Figure 4) was not significantly different between trials (F 1, 9 = 0.317, P = 0.587, Pη2 = 0.034). Carbohydrate oxidation remained relatively constant throughout exercise but was higher compared with the rest (F 2, 18 = 13.902, P < 0.001, Pη2 = 0.770). The rate of fat oxidation (Figure 5) was higher than that at rest during exercise (F 1, 11 = 25.131, P < 0.001, Pη2 = 0.736) but there was no significant main effect due to the substances ingested (F 1, 9 = 0.950, P = 0.355, Pη2 = 0.095).
