ConclusionsĪcute caffeine intake (3 mg/kg) improved muscular strength, power and endurance performance, revealing a more pronounced effect at high-loads (≥ 75% 1RM) and in lower-body (back squat) than in upper-body exercise (bench press) according to muscle group size.Ĭhester N, Wojek N (2008) Caffeine consumption amongst British athletes following changes to the 2004 WADA prohibited list. No differences were found in bench press exercise. Isometric handgrip, isometric mid-thigh pull and vertical jump tests were also performed. Sixty minutes after ingestion, they performed muscular strength and power assessment for bench press and back squat exercise at 25%, 50%, 75% and 90% 1-repetition-maximum (1RM), performing 3, 2, 1 and 1 repetitions respectively, followed by muscular endurance assessment for both exercises at 65% and 85% 1RM performing until task failure. Participants were provided with either 3 mg/kg of body mass of caffeine or maltodextrin (placebo). ![]() Twenty resistance-trained athletes (male/female: 10/10 age: 23 ± 4 years body mass: 70.6 ± 15.1) participated in a double-blind, placebo-controlled, cross-over and randomized study. Thus, this study aimed to examine the effects of acute caffeine intake on upper and lower-body muscular strength, power and endurance performance at different loads. ![]() Although acute caffeine intake seems to improve muscular strength–power–endurance performance, there is scarce evidence evaluating upper vs lower-body exercises at different loads. ![]()
