Comparison of stroke volume estimation for non-steady-state and steady-state graded exercise testing.

abstract：BACKGROUND:Previous studies have reported the non-homogenous loss of muscle mass (site-specific muscle loss) with ageing, but this relationship to the loss of strength is not totally understood. PURPOSE:To investigate the relationship between maximal dynamic strength and site-specific muscle mass of the thigh and uppe...
