Table 1.

HR, SV, MAP, and CO across three ranges of knee joint angle

	Lower 15%	Middle 15%	Upper 15%
HR, beats/min	58 ± 7	59 ± 8	59 ± 7
SV, ml	111 ± 20	111 ± 21	111 ± 21
MAP, mmHg	88 ± 9	87 ± 9	86 ± 8
CO, l/min	6.5 ± 1.7	6.5 ± 1.7	6.6 ± 1.7
Conductance, ml · min−1 · mmHg−1	2.4 ± 0.8†	3.2 ± 1.1*	3.6 ± 1.1*†

Values are means ± SD. HR, heart rate; SV, stroke volume; MAP, mean arterial pressure; CO, cardiac output.

^*Significant difference from the lower 15% range of knee joint.
