A prior study in men showed similar, albeit slightly less profound, results (Morris et al. 1993; Myers et al. 2002). For men, research has shown that for every 1 MET increase in exercise capacity, there is a 12% improvement in survival (Myers et al. 2002). To make this information more accessible, the authors of these studies developed a nomogram (Figure 1) that you can use to determine your clients' exercise capacity relative to their age-predicted values.   As a practical example, according to the nomogram shown in Figure 1, a 35-year-old woman should be able to reach about 10.5 METs and a 65-year-old man should be able to reach about 7.5 METs. These values represent the averages for their ages; anything below these levels is associated with greater risk of death.   For running 6 mph (10 minutes per mile), the Compendium shows a value of 10 METS. If someone ran for 30 minutes at this pace, then they would earn 10 x 30 = 300 MET-minutes.   For biking on a level surface at 12.5 mph, the Compendium shows a value of 8 METS. If someone biked for 45 minutes at this pace, then they would earn 8 x 45 = 360 MET-minutes.   https://www.cooperinstitute.org/2017/12/07/using-met-minutes-to-track-volume-of-physical-activity   --------------------------------
