Table 2.

Delays (beats) of the response peak of heart rate (HR), MSNA, and mean blood pressure (MAP) from the onset of passive stretch or active contraction

	Spontaneous breathing		Controlled breathing
	Stretch	Contraction	Stretch	Contraction
Delay of HR	2.0 ± 0.3	2.0 ± 0.3	1.8 ± 0.3	2.3 ± 0.3
Delay of MSNA	1.2 ± 0.3	1.2 ± 0.3	1.0 ± 0.3	1.6 ± 0.3
Delay of MAP	3.5 ± 0.4	3.1 ± 0.4	3.7 ± 0.4	3.0 ± 0.5

There was no significant difference in the delays between the conditions. Subject numbers for the respective condition are shown in Table 1.
