Table 2.

Cardiorespiratory responses during 5 min of baseline and fatiguing isometric handgrip exercise with SB and CB

Breathing Condition	P_{ET_CO₂}, mmHg	V_T, liters	RR, breaths/min	V̇_E, l/min	HR, beats/min	MAP, mmHg	Force Output, %MVC
SB baseline	38.9 (5.0)	0.72 (0.23)	13.7 (2.6)	12.2 (7.0)	57 (8)	83 (8)
SB exercise	36.9 (5.7)	0.99 (0.39)	19.7 (7.5)^*	19.3 (11.4)	78 (14)^*	102 (6)^*	19.8 (4.7)
CB baseline	41.7 (3.3)	1.12 (0.22)^*	20.2 (0.1)^*	22.6 (4.4)^*	61 (8)	86 (7)
CB exercise	42.2 (3.5)	1.21 (0.22)	20.5 (0.9)	24.8 (4.7)	74 (12)^‡	99 (10)^†	17.8 (5.3)

Values are mean (SD); n = 8. %MVC, percentage of maximal voluntary contraction.

P < 0.05, significantly different from SB baseline.
