DMH disinhibition also precipitated multiple ventricular and supraventricular ectopic beats. DMH-induced increases in HR, LVP, LVdP/dt, and in the number of ectopic beats dependent on the side of stimulation, with R-DMH provoking larger responses. In contrast, pressor and respiratory responses did not depend on the side of stimulation. Newly described DMH-induced inotropic responses were rate-, preload- and (largely) afterload-independent; they were mediated by sympathetic cardiac pathway, as revealed by their sensitivity to β-adrenergic blockade. We conclude that recruitment of DMH neurons causes sympathetically mediated positive chronotropic and inotropic effects, and that there is an asymmetry, at the level of the DMH, in the potency to elicit these effects, with R-DMH > L-DMH.]]> Sat 24 Mar 2018 07:59:52 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17969 Sat 24 Mar 2018 07:56:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21111 t-tests (p = 0.05) were used to examine differences between dominant and nondominant trials. Independent t-tests (p- = 0.05) were used to identify differences between left and right leg dominant groups. The current version of the AFL agility test appropriately examined ~61% of footballers in this cohort. The remaining ~39% produced significantly faster times during the alternate version (0.63-0.82 seconds; p = 0.001). All footballers demonstrated a performance deficit of 5-10% between limbs (~0.72 seconds; p = 0.001). Limb dominance (directional preference) was evident for all footballers. Change of direction capabilities should therefore be examined bilaterally to eliminate bias toward athletes with particular leg dominance profiles and to provide a limb deficit measure for enhanced athletic profiling outcomes.]]> Sat 24 Mar 2018 07:54:00 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50977 Mon 14 Aug 2023 15:24:38 AEST ]]>
