Strength and hypertrophy with resistance training: chasing a hormonal ghost

I am writing with regards to the article recently published in the European Journal of Applied Physiology by Rønnestad et al. ( 2011). The authors report in their abstract that “only L + A [leg plus arm training—a high ‘anabolic’ hormonal exposure condition] achieved increase in the CSA at the part of the arm flexors with the largest cross-sectional area ( p < 0.001), while no changes occurred in A [arm only training—a low ‘anabolic’ hormonal exposure condition].” Oddly, examination of Fig. 6 in their paper reveals that significant hypertrophy did occur at two sites (of 4 measured) in the A arm, which is misleading by comparison not only to the statement in their abstract but also to a redrawing of their same figure (see Fig. 1). Additionally, a finding for which incomplete statistical analysis was reported was the change in muscle volume which was not different between the A and the L + A arms. Since the change in muscle volume would be the product of the change in muscle...
