Fig. 5.
Age differences in myofiber contractile function at baseline and with training. Top: baseline differences in myofiber contractile function expressed as percent difference from YM. Bottom: percent change in myofiber contractile function with training for OM in relation to YM, determined by the percent difference from YM posttraining minus percent difference from YM pretraining. A positive value represents an improvement in contractile function for OM relative to the YM. *P < 0.05 between groups. $P < 0.10 between groups.
