Background: To examine the effect of acute R.Rosea ingestion, acute caffeine ingestion or combined caffeine and R.Rosea on 5km running time trial performance. Methods: Twelve male, recreational exercisers (mean age ± S.D. = 24.6 ± 6 years) undertook 4 trials each (Placebo; Caffeine (3 mg/kg-1), R.Rosea (3 mg/kg-1), Caffeine (3 mg/kg-1) and R.Rosea (3 mg/kg-1)) in a double blind, randomised order. Results: There was a small but significant main effect of treatment for 5km run time (P = .048) where performance was faster in the presence of caffeine compared to placebo but not between any other combination of trials. Heart Rate, Blood Lactate and RPE all increased with Km run, irrespective of substance ingested (all P
