VO2max and grip strength, against published norms
Cardiorespiratory fitness and grip strength are two of the measurements most often linked with how people age. This page places a measurement against the published reference tables for people of the same sex and age, using the tables’ own numbers.

The method and its sources
VO2max The most oxygen the body can use during all-out exercise, a standard measure of aerobic fitness.: the FRIEND registry reference standards, Kaminsky LA et al., Mayo Clinic Proceedings 2015 (PMID 26455884), Table 3: treadmill tests with oxygen uptake measured directly, in 7,783 men and women in the United States free of known cardiovascular disease, by decade from 20 to 79.
Grip strength: Dodds RM et al., PLoS One 2014 (PMID 25474696), Table 2: 60,803 measurements from 49,964 people in twelve British general-population studies, maximum grip of either hand by dynamometer, centiles at five-year ages from 20 to 90.
The tables give a handful of percentiles each. The result says which two published percentiles a value falls between and does not invent one in between. A grip age between two table ages uses the nearest one, and the result names it.
