The average (± S.D.) core temperature, psychophysical ratings, and brachial artery (a.) blood pressure and heart rate, prior to performing sets of brief contractions in the second experiment

Variable	Control	Hyperthermia
Core temperature (°C)	37.2 ± 0.3	38.5 ± 0.4*
Thermal sensation	7.6 ± 0.6 (neutral to slightly warm)	10.3 ± 1.0* (hot to very hot)
Thermal discomfort	1.2 ± 0.3 (comfortable)	2.9 ± 1.1* (uncomfortable)
Brachial a. SBP (mmHg)	112 ± 8	118 ± 12*
Brachial a. DBP (mmHg)	70 ± 11	63 ± 9*
Brachial a. MAP (mmHg)	84 ± 9	81 ± 8
Brachial a. HR (beats min−1)	74 ± 17	112 ± 21*

Data were collected with a normal core temperature (control) and during hyperthermia.

^*Significant difference between the control and hyperthermic conditions (P < 0.05).

SBP, systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial pressure; HR, heart rate.
