From: Ultrasound assessment of lower limb muscle mass in response to resistance training in COPD
Percentage change from baseline in ultrasound and DEXA measured indices of quadriceps mass in (a) COPD, and (b) Healthy. Data presented as Means (SEM) RF csa : Rectus femoris cross-sectional area measured by ultrasound, Q t : Quadriceps muscle thickness measured by ultrasound, T dexa : Thigh lean mass measured by DEXA, Wilcoxon Signed rank test: *** p ≤ 0.0001; ** p < 0.001; * p < 0.01, significantly different from baseline.
