Commentaries on viewpoint: control arms in exercise training studies: transitioning from an era of intervention efficacy to one of comparative clinical effectiveness research.

摘要

to the editor: It was with great interest that I read the Journal of Applied Physiology Viewpoint on control arms in exercise training studies: transitioning from an era of intervention efficacy to one of comparative clinical effectiveness research (1). I believe, as do the authors, in the importance of discussing continuously the code of ethics while we continue to do research. The Viewpoint(s), however, opens up for debate.
