<b>NORADRENERGIC REGULATION OF SKELETAL MUSCLE OXYGEN PRESSURES: IMPACT OF HFpEF AND HEAT THERAPY</b>

<p dir="ltr">This study explored functional sympatholysis—the attenuation of sympathetic vasoconstriction during muscle contraction—by assessing oxygen diffusion dynamics in the rat spinotrapezius muscle using phosphorescence quenching techniques.</p>
