Abstract
Background
The effect of concurrent training on the development of maximal strength is unclear, especially in individuals with different training statuses.
Objective
The aim of this systematic review and meta-analysis study was to compare the effect of concurrent resistance and endurance training with that of resistance training only on the development of maximal dynamic strength in untrained, moderately trained, and trained individuals.
Methods
On the basis of the predetermined criteria, 27 studies that compared effects between concurrent and resistance training only on lower-body 1-repetition maximum (1RM) strength were included. The effect size (ES), calculated as the standardised difference in mean, was extracted from each study, pooled, and analysed with a random-effects model.
Results
The 1RM for leg press and squat exercises was negatively affected by concurrent training in trained individuals (ES = – 0.35, p
Description
This study reviews the effects of concurrent training on strength development across different training statuses.
