Abstract | Caffeine's metabolic and performance effects have been widely reported. However, caffeine's effects on affective states during prolonged exercise are unknown. Therefore, this was examined in the present study. Following an overnight fast and in a randomised, double-blind, counterbalanced design, twelve endurance trained male cyclists performed 90min of exercise at 70% VO2 max 1h after ingesting 6mgkg-1BM of caffeine (CAF) or placebo (PLA). Dimensions of affect and perceived exertion were assessed at regular intervals. During exercise, pleasure ratings were better maintained (F(3,38)=4.99, P<0.05) in the CAF trial compared to the PLA trial with significantly higher ratings at 15, 30 and 75min (all P<0.05). Perceived exertion increased (F(3,28)=19.86, P<0.01) throughout exercise and values, overall, were significantly lower (F(1,11)=9.26, P<0.05) in the CAF trial compared to the PLA trial. Perceived arousal was elevated during exercise but did not differ between trials. Overall, the results suggest that a moderate dose of CAF ingested 1h prior to exercise maintains a more positive subjective experience during prolonged cycling. This observation may partially explain caffeine's ergogenic effects. © 2011 Elsevier Ltd. |
