Effect Of Coffee And Caffeine Ingestion On Resistance Exercise Performance

The aim of the present study was to determine the effect on performance of ingesting caffeine-dose matched anhydrous caffeine, coffee or decaffeinated coffee plus anhydrous caffeine during resistance exercise. Nine resistance trained males (Mean+/-SD age: 24+/-2 years, weight: 84+/-8kg, height: 180+/-8cm) completed a squat and bench press exercise protocol at 60% 1-RM until failure on five occasions consuming either, 0.15 g[middle dot]kg-1 caffeinated coffee (COF), 0.15 g[middle dot]kg-1 decaffeinated coffee (DEC), 0.15 g[middle dot]kg-1 decaffeinated coffee plus 5 mg[middle dot]kg-1 anhydrous caffeine (D+C), 5 mg[middle dot]kg-1 anhydrous caffeine (CAF) or a placebo (PLA). Felt arousal and rating of perceived exertion (RPE) were used to assess perceptual variables and heart rate (HR) to assess physiological responses between trials. There were significant differences in total weight lifted for the squat between conditions (P
