Maximal work rate, oxygen consumption, and heart rate in centenarians and young controls at the end of a graded exercise test to maximum effort

	Centenarians (N = 8)		Young (N = 8)		P value
	Mean ± SD	Range	Mean ± SD	Range	P value
Maximal work rate (watts)	33 ± 4	(25–35)	179 ± 24	(215–140)	<0.001
VO_2peak (ml min⁻¹ kg⁻¹)	7.5 ± 1.1	(6.1–9.3)	39.6 ± 3.5	(36.5–46.7)	<0.001
HR_peak (beats min⁻¹)	102 ± 4	(97–109)	178 ± 10	(166–190)	<0.001

VO_2peak represents peak of oxygen consumption, and HR_peak represents peak heart rate. Data expressed as mean ± SD
