B · Reasonable confidenceSecond meta-analysis: training to failure vs not for strength, growth, power
Subject: Training to failure or not: strength, hypertrophy and power
What this means
No difference in maximal strength (SMD -0.08, p=0.642). Hypertrophy: failure better (SMD 0.75, p=0.005), but no difference with equated volume. Power: no difference (SMD -0.20, p=0.239), but with non-equated volume non-failure better (SMD -0.61, p=0.025). 13 studies, adults, intervention ≥6 weeks.

What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
A second, independent analysis of whether training to muscle failure produces more strength and muscle growth, with a similar conclusion to the earlier meta-analysis on this topic in this library.
Who this applies to
Adults, mixed training status.
Size of the research
13 studies.
What to keep in mind
Hypertrophy result (failure better) disappeared with equated volume; small sample; heterogeneity.
Practical conclusion for REZA
Two independent meta-analyses pointing the same direction make this one of the sturdier-supported choices in REZA's programming.
