Mean (±SD) heart rate responses at 1G_z, 0.38G_z and μG

Mean (±SD), bpm					ECC guidelines
Baseline	Heart rate	1Gz	0.38Gz	μG
84 (±15)	HR post-ECC	111 (±19)	132 (±23)*	159 (±19)*	2005
	%Δ	33.8 (±18.4)	60.0 (±25.8)*	94.7 (±33.9)*
	%Max	56.1 (±9.4)	66.9 (±11.6)*	80.7 (±9.9)*
	HR post-ECC	117 (±21)	140 (±21)*	163 (±18)*	2010
	%Δ	41.4 (±22.8)	71.2 (±30.5)*	98.8 (±35.4)*
	%Max	59.2 (±10.9)	71.1 (±10.7)*	82.3 (±9.4)*

HR responses are depicted as baseline and post-ECC values (bpm), percent change from baseline and percentage of maximum heart rate (maximum heart rate was calculated using the 220-age equation). n = 30; *p < 0.05, significant difference from 1G_z control.
