Objectives The aim of the present study was to perform a systematic review and meta-analysis of the acute effects of caffeine ingestion on maximal strength and muscular endurance in isotonic resistance exercises. Equipment and methods Up until March 2015, 17 studies which met the inclusion criteria, 42 trials related to muscular endurance and 5 trials related to muscular strength, were found from a search in the following databases: PubMed, ISI Web of Knowledge, SportDiscus, Scielo, Lilacs, Medcarib, Ibecs and ProQuest Dissertations & Theses. The effect sizes were calculated as the standardized mean difference and meta-analysis were completed using a random-effects model. Results No significant effects were identified for gender, muscle location, muscle size, dosage of caffeine or form or timing of pre-exercise caffeine consumption on performance at maximum strength. For muscular endurance, all moderators were related to improve performance after caffeine intake (P<0.01). The between groups analysis showed no differences with regard to the effect sizes in the comparisons for muscle location (P=0.09); muscle size (P=0.12); caffeine dosage (P=0.08); and form of intake (P=0.24). Effect size related to time of consumption pre-exercise was significant only for 60min, with significant differences vs. 45min and 90min (P=0.04). Comparisons between gender groups were not possible, since only one trial investigated females. |
