Resistance training prescription for muscle strength and hypertrophy in healthy adults: a systematic review and Bayesian network meta-analysis

Abstract: ObjectiveTo determine how distinct combinations of resistance training prescription (RTx) variables (load, sets and frequency) affect muscle strength and hypertrophy.Data sourcesMEDLINE, Embase, Emcare, SPORTDiscus, CINAHL, and Web of Science were searched until February 2022.Eligibility criteriaRandomised trials that included healthy adults, compared at least 2 predefined conditions (non-exercise control (CTRL) and 12 RTx, differentiated by load, sets and/or weekly frequency), and reported muscle strength and… Show more

“…PROMIS outcomes in this study were collected on a time threshold rather than after a certain number of visits. participating in strength training as part of their treatment or for patients building a therapeutic alliance with their provider (Clewley et al, 2020;Currier et al, 2023;Ferreira et al, 2013;Hall et al, 2010;Rand et al, 2007). This may have had an effect on perception and outcomes as patients may have been attending at a variety of frequencies and receiving a variety of treatments (Clewley et al, 2020) over the 6-week collection period, but this was not controlled for in this study.…”

“…Training volume also plays a significant role in training outcomes, particularly for hypertrophy ( Currier et al, 2023 ); however, more may not always be better and may come at a cost. When comparing 12–20 sets per muscle group per week to 20+, there were no significant differences in muscle hypertrophy for most muscle groups ( Baz-Valle et al, 2022 ).…”

“…The guidelines suggest up to four sets of an exercise per week for an untrained individual and up to 10 sets per week for trained individuals [31]. However, similar to the increasing load guidelines above, a recent network meta‐analysis suggests that performing resistance training 2–3 times per week achieves the greatest muscle strength and hypertrophy gains [34].…”
