Background: Current recommendations on resistance training RT frequency for gains in muscular strength are based on extrapolations from limited evidence on the topic, and thus their practical applicability remains questionable. Objective: To elucidate this issue, we conducted a systematic review and meta-analysis of the studies that compared muscular strength outcomes with different RT frequencies. The meta-analysis was performed using a random-effects model. The methodological quality of studies was appraised using the modified Downs and Black checklist. Results: A total of 22 studies were found to meet the inclusion criteria.
