Mean estimates of study phenotypes by genotypes of the K153R (rs1805086) polymorphism in the <i>GDF8</i> gene in men.

<p>Values are means (standard deviation).</p><p>P values related to group differences (one way analysis of covariance after adjusting for age, weight and height).</p><p>Cohen's <i>d</i> (standardized mean differences) and 95% confidence interval (CI). Values of d 0.2, 0.5 and 0.8 are considered small, medium and large effects, respectively.</p><p>Abbreviations: SJ, squat jump; CMJ, counter-movement jump; CG, centre of gravity.</p
