Unlabelled
Caffeine is thought to act as a central stimulant and to have effects on physical, cognitive, and psychomotor functioning.
Purpose
To examine the effects of ingesting a performance bar, containing caffeine, before and during cycling exercise on physical and cognitive performance.
Methods
Twenty-four well-trained cyclists consumed the products [a performance bar containing 45 g of carbohydrate and 100 mg of caffeine (CAF), an isocaloric noncaffeine performance bar (CHO), or 300 mL of placebo beverage (BEV)] immediately before performing a 2.5-h exercise at 60% VO2max followed by a time to exhaustion trial (T2EX) at 75% VO2max. Additional products were taken after 55 and 115 min of exercise. Cognitive function measures (computerized Stroop and Rapid Visual Information Processing tests) were performed before exercise and while cycling after 70 and 140 min of exercise and again 5 min after completing the T2EX ride.
Results
Participants were significantly faster after CAF when compared with CHO on both the computerized complex information processing tests, particularly after 140 min and after the T2EX ride (P 0.10). T2EX was longer after CAF consumption compared with both CHO and BEV trials (P 0.05).
Conclusion
Caffeine in a performance bar can significantly improve endurance performance and complex cognitive ability during and after exercise. These effects may be salient for sports performance in which concentration plays a major role.
