BEffect of Resistance Training Frequency on Gains in Muscular Strength: A Systematic Review and Meta-Analysis
Grgic J, Schoenfeld BJ, Davies TB, Lazinica B, Krieger JW, Pedisic Z · 2018 · Sports Medicine
REZA evidence rating B: Reasonable confidence
Methodology
Meta-analysis
Population
22 studies; mostly untrained participants, mixed age groups
Intervention
Different training frequencies (1, 2, 3+ days/week) vs lower frequencies
Findings
Higher training frequency was associated with greater strength gains. Volume-equated analyses showed a trend favouring higher frequency, but the practical significance is limited once volume is matched.
Outcome measures
Maximal strength (1RM)
Limitations
Most studies untrained; few volume-equated studies; heterogeneity in exercise selection.
