... In the extended model, men with total testosterone levels in the highest 25% (4th quartile) had more lower-body lean mass (LBLM) (β=22.1(%), 95%CI: 9.0, 35.3, p=0.003) and upper-body lean mass (UBLM) (β=5.6(%)...
... Skeletal muscle hypertrophy in the absence of exogenous testosterone supplementation is localized to the muscle or muscles that are stressed through physical activity. The association seen in this study between lower-body lean mass and testosterone levels could be the result of muscle growth caused by daily walking while exposed to chronically higher levels of testosterone that still fall within the normal range, as ambulatory activity has been previously associated with lower-body muscular adaptations (Ozaki et al. 2013). However, our analysis of this data suggest no interaction between physical activity levels and testosterone on lower-body lean mass (interaction term: p = .94). It is possible that our interpretation was limited by the selfreported measure of physical activity which may be incapable of differentiating small but meaningful differences in physical activity, particularly incidental-based physical activity...
... The association between testosterone dose (by quartile) and relative lean and fat body mass for the previously mentioned four models for both total testosterone and free testosterone were examined using a modified extended model that did not include body mass as a covariate. Relative amounts of mass to body mass were calculated by dividing lean and fat mass compartments in the upper and lower body by body mass and multiplying by 100 (e.g., (LBLM / body mass) * 100, (LBFM / body mass) * 100). Statistical significance was set at p ≤ 0.05...
так там что то вообще смешные цифры по мясу выходят ... и анализ физактивности методом опросника ... и вся активность сведена к ходьбе и приросту в ногах ...
это сколько получается прибавка вверху, при бета-коэффициенте 5.6% и 7,2 кг относительного кол-ва мяса?
