Effects of local and whole body heating on heart rate, blood pressure, and muscle vascular conductance and resistance

	Normothermic Baseline	Local Heating	Whole Body Heating
Heart rate, beats/min	57 ± 7	63 ± 9	99 ± 9*†
Systolic arterial blood pressure, mmHg	120 ± 13	122 ± 12	123 ± 9
Diastolic arterial blood pressure, mmHg	69 ± 8	67 ± 6	54 ± 7*†
Mean arterial blood pressure, mmHg	86 ± 8	85 ± 7	77 ± 7*†
Muscle vascular conductance (covered), ml · 100 g−1 · min−1 · mmHg−1	0.016 ± 0.005	0.026 ± 0.013	0.025 ± 0.007*
		(P = 0.06)
Muscle vascular resistance (covered), mmHg · ml−1 · 100 g · min	70.1 ± 27.8	43.8 ± 14.8*	44.3 ± 16.7*
Muscle vascular conductance (uncovered), ml · 100 g−1 · min−1 · mmHg−1	0.018 ± 0.006	0.018 ± 0.006	0.022 ± 0.006
Muscle vascular resistance (uncovered), mmHg · ml−1 · 100 g · min	60.5 ± 21.0	62.1 ± 20.2	48.9 ± 13.7

Values are means ± SD. Covered: the right calf that was covered by the water-perfused suit and thus was directly heated during both local and whole body heating; uncovered: the left calf that was not covered by the water-perfused suit and thus was not directly heated at any time.

^*P < 0.05 compared with normothermic baseline;

^†P < 0.05 compared with local heating.
