Adaptive changes in physiological and perceptual responses during 10-day heat acclimation training using a water-perfused suit

Table 1 Characteristics of subjects in each experimental group

	HA_EXE (N = 6)	HA_EXE+SUIT (N = 6)	HA_SUIT (N = 7)	P value
Age (years)	22 ± 2	22 ± 2	24 ± 2	N.S.
Height (cm)	174 ± 2.2	174.8 ± 5.0	175.7 ± 6.0	N.S.
Body weight (kg)	69.5 ± 7.9	69.1 ± 10.2	71.7 ± 10.4	N.S.
Body surface area (m²)^a	1.9 ± 0.1	1.9 ± 0.1	1.9 ± 0.1	N.S.
Perceived heat tolerance^b	3 ± 2	3 ± 2	4 ± 1	N.S.
VO_2max (mL^·min^·kg⁻¹)	47.5 ± 9.1	46.6 ± 6.8	47.5 ± 1.5	N.S.

All data were expressed as mean ± SD (standard deviation)
^aBody surface area was estimated using the equation from Lee et al. [18]
^bPerceived heat tolerance was attained with following 7-point scale: 1, I am very susceptible to heat; 2, I am susceptible to heat; 3, I am a little susceptible to heat; 4, I am neither susceptible nor tolerant to heat; 5, I am a little tolerant to heat; 6, I am tolerant to heat; 7, I am very tolerant to heat
