Note: Values are means ± SD. bpm = beats per minute; DBP = diastolic blood pressure; OA = men aged between 55 and 75 years who exercise at least 15 h/mo; OS = physically inactive men aged between 55 and 75 years; SBP = systolic blood pressure; VO2max = maximal oxygen consumption; YS = physically inactive men aged between 18 and 30 years. Groups sharing a common symbol significantly different at p < .05.
* p < .05 between YS/OS.
† p < .05 between OA/OS.
