furthermore , variations in bmax of the three skeletal muscles were directly related to percentage of type i fibers ( r = 0.99 ; p less than 0.001 ) , which had a beta-receptor density that was approximately 4.5-fold greater than in superficially located type iib fibers , 3.2-fold greater than in intermediate depth type iib fibers , and 2.0-fold greater than in type iia fibers .
