In two additional sessions (no infusion), lower-body negative (LBNP) or positive (LBPP) pressure was applied throughout the final 45 min of recovery. Local sweat rate (LSR; ventilated capsule: chest, forearm, upper back, forehead) and skin blood flow (SkBF; laser-Doppler flowmetry: forearm, upper back) were continuously measured. During HYP, upper back LSR was attenuated from end-exercise to 10 min of recovery by \u223c0.35 \u00b1 0.10 mg\u00b7min(-1)\u00b7cm(-2) and during the last 20 min of recovery by \u223c0.13 \u00b1 0.03 mg\u00b7min(-1)\u00b7cm(-2), while chest LSR was lower by 0.18 \u00b1 0.06 mg\u00b7min(-1)\u00b7cm(-2) at 50 min of recovery compared with natural recovery (all P &lt; 0.05).<\/p>\n<p>Forearm and forehead LSRs were not affected by plasma hyperosmolality during HYP (all P &gt; 0.28), which suggests regional differences in the osmotic modulation of postexercise LSR. Furthermore, LBPP application attenuated LSR by \u223c0.07-0.28 mg\u00b7min(-1)\u00b7cm(-2) during the last 30 min of recovery at all sites except the forehead compared with natural recovery (all P &lt; 0.05). Relative to natural recovery, forearm and upper back SkBF were elevated during LBPP, ISO, and HYP by \u223c6-10% by the end of recovery (all P &lt; 0.05). We conclude that 1) hyperosmolality attenuates postexercise sweating heterogeneously among skin regions, and 2) baroreceptor loading modulates postexercise SkBF independently of changes in plasma osmolality without regional differences.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/journals.physiology.org\/doi\/pdf\/10.1152\/ajpregu.00435.2015\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/journals.physiology.org\/doi\/pdf\/10.1152\/ajpregu.00435.2015<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-8302 size-full\" src=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2021\/11\/Line.png\" alt=\"\" width=\"1316\" height=\"1\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Paull G, Dervis S, Barrera-Ramirez J, McGinn R, Haqani B, Flouris AD, Kenny GP.
