REZA evidence rating B: Reasonable confidence
Methodology
Meta-analysis
Population
111 studies, 158 groups, 1,927 healthy males aged 18-40; mixed training status from sedentary to 4+ years experience
Intervention
Resistance training interventions ≥2 weeks to 1 year
Findings
Resistance training produced significant increases in fat-free mass, lean muscle mass, and skeletal muscle mass. Volume was a significant moderator of hypertrophy, with more experienced trainees showing smaller gains than novices.
Outcome measures
Fat-free mass (FFM), lean muscle mass (LMM), skeletal muscle mass (SMM)
Limitations
Males only; ages 18-40 only; heterogeneity high (I² up to 80%); publication bias possible; measurement methods varied.
