Fig 2. $\stackrel{.}{\mathbf{V}}{\mathbf{O}}_{\mathbf{2}\mathbf{\text{max}}}$ forest plot.

Effect sizes represent the change in $\stackrel{.}{\mathrm{V}}{\mathrm{O}}_{2\text{max}}$ post-intervention. For all plots the 95% confidence intervals were calculated and the overall mean effect size is represented with the diamond, whereas, the black squares are the individual effect size of each study. The weighting is adjusted for sample size, SD and variance. Where G1 = group 1 and G2 = group 2. Genes listed in alphabetical order.
