WebDec 1, 2002 · The underlying hypothesis is that myogenic behavior can be partitioned into three distinct phases and that different cellular mechanisms may contribute to different degrees in each phase. For example, phase 1 (the development of tone) involves cellular deformation, depolarization, and significant increases in arterial wall calcium. WebWe tested the hypothesis that older males (OMs, 70±4 yr, n=9) would have a blunted myogenic response to a physiological stimulus compared to younger controls (21±3 yr, n=9). Subjects completed an acute bout of intense unilateral muscle loading. Young healthy males matched for body mass and activity level served as the control group. dental records how long to keep
