Introduction to the symposium: resistive weight training: a new approach to exercise for cardiac and coronary disease prone populations.

abstract：PURPOSE:Strain magnitude is known to be a primary determinant of the osteogenic response to loading. However, whether bone adaptation to muscle loading is determined primarily by load magnitude is unclear. The purpose of this study was to determine the contribution of load magnitude from muscle action on the site-speci...
