From: Weekly Training Frequency Effects on Strength Gain: A Meta-Analysis
Low vs. medium weekly training frequency. Pre- vs. post-mean ES strength difference on upper body exercise. The vertical line indicates the overall estimate of combined multi-joint and isolation studies pre- vs. post-mean ES strength difference. Horizontal lines indicate 95% CI, squares estimates, whereas square size is proportional to sample size, and rhombs’ meta-analytically pooled estimates
