Metabolic adaptation
Gross variability in resistance training outcomes often reflects confounding sources of within-participant variation rather than true inter-individual differences.
Practitioners should be cautious in interpreting variability in training outcomes.
StrongSupportsmedium confidence
Gross variability in resistance training outcomes is commonly interpreted as evidence of meaningful inter-individual response variation (IRV), but this variability often reflects confounding sources of within-participant variation rather than true inter-individual differences.
Why this rating
The claim is supported by the study's findings and broader implications.
