View on ClinicalTrials.gov →
Summary
Evidence regarding the ergogenic effects of caffeine is well-established in young adults, but evidence in older adults remains scarce, particularly during dynamic resistance exercise. Therefore, this study investigated the effects of acute caffeine ingestion on upper- and lower-body muscular strength and endurance performance, as well as the influence of sex and CYP1A2 genotype, in healthy resistance training-naïve older adults.
