Body weights, colonic temperature, heart rate, and LV mass in the experimental groups

	Number	Control	AC	EX	EXAC
Body weight,g	12	291 ± 9.5	254 ± 12.4*	255 ± 9.7*	225 ± 7.4*
Heart rate, beats/min	5	332 ± 8.3	307 ± 6.3*	334 ± 30.5	292 ± 7.7*
LV mass, g	5	1.207 ± 0.04	1.1 ± 0.03*	1.028 ± 0.05*	0.961 ± 0.06*
