The aim of this study was to examine the effect of acute Rhodiola rosea (R. rosea) ingestion on substrate utilisation, mood state, @entity4935 , 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 @entity4935 were recorded. @entity1 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 @entity4935 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. @entity17393 compared to placebo (P = 0.008). There were no significant differences in energy expenditure, @entity1735 , or fat oxidation between conditions (P > 0.05). Ingestion of R. rosea favourably influenced @entity4935 and exercise affect without changes in energy expenditure or substrate utilization during 30-minute submaximal cycling performance.
