PURPOSE: The purpose of this investigation is to examine the impact of different levels of caffeine on aerobic performance and muscle strength. METHODS: Twelve participants (7 male, 5 female; age = 25.0 ± 1.3 years; weight = 78.6 ± 3.6 kg; height = 1.72 ± 3.54 m) completed four experimental sessions. During the first session, participants were familiarized with all procedures used in the experimental sessions. During the three experimental sessions, subjects completed the hand grip test and a 5-km time trial. Hand grip strength was assessed using the Jamar Plus Digital Hand Dynamometer. The 5-km time trial was completed on a Lode Corival CPET cycle ergometer. Prior to each experimental session, subjects consumed a 12-oz coffee beverage with decaffeinated coffee (PLAC), 220 mg (MID), or 450 mg (HIGH) of caffeine. Treatments were blinded to participants and applied in a randomized order. Subjects completed experimental sessions after a 4-hour food and 12-hour caffeine fast. RESULTS: Hand grip strength was greater during the HIGH (44.5 ± 3.6 kg) condition compared to PLAC (41.8 ± 3.2 kg) and MID (42.7 ± 3.2 kg) (p = 0.01). Subjects completed the 5-km time trial more quickly during the HIGH (6.1 ± 0.5 min) condition compared to PLAC (7.8 ± 1.0 min) (p = 0.03) and MID (7.5 ± 0.8 min) (p = 0.04). CONCLUSION: These findings indicate that the level of caffeine consumption can simultaneously impact anaerobic exercise performance and muscle strength.}, journal={Medicine & Science in Sports & Exercise}, author={Bailey, Stephen and Momplaisir, Emilize and Cooper, Stella and Oliver, Clarke and Whitaker, Maddie and Harris, G Keith}, year={2025}, month={Sep} }

PURPOSE: The purpose of this investigation is to examine the impact of different levels of caffeine on anaerobic exercise performance. METHODS: Twelve participants (7 male, 5 female; age = 25.0 ± 1.3 years; weight = 78.6 ± 3.6 kg; height = 1.72 ± 3.54 m) completed four experimental sessions. During the first session, participants were familiarized with all procedures used in the experimental sessions. During the three experimental sessions, subjects completed the following assessments of anaerobic performance: countermovement jump (CMJ), leg press, and shoulder flexion dynamometry. Prior to each experimental session, subjects consumed a 12-oz coffee beverage with decaffeinated coffee (PLAC), 220 mg (MID), or 450 mg (HIGH) of caffeine. Treatments were blinded to participants and applied in a randomized order. Subjects completed experimental sessions after a 4-hour food and 12-hour caffeine fast. RESULTS: Dynamic strength index during CMJ was greater during the HIGH (3.07 ± 0.32 cm.sec-1) condition compared to PLAC (2.56 ± 0.23 cm.sec-1) and MID (2.90 ± 0.31 cm.sec-1) (p = 0.01). Force generated during the shoulder press was greater during HIGH (87.9 ± 6.8 N) than in PLAC (77.2 ± 5.8 N) and MID (77.6 ± 6.0 N) (p = 0.03). Maximal force generated during the leg press was higher during HIGH (1813 ± 210 N) than in PLAC (1501 ± 144 N) (p = 0.02).
