VO2 max levels in older adults?

VO2 max levels are a critical measure of cardiovascular fitness and are especially important in older adults. A study involving VO2 max tests on older individuals, including those as old as 92, illustrated that those with VO2 max levels below 18 may require assisted living. This low level indicates a significant decline in fitness, which compromises the ability to live independently. In contrast, the study found that some exceptionally fit older adults, specifically Swedish cross country skiers, had VO2 max scores that rivaled those of much younger individuals, around 35 to 38, which is comparable to normal college-aged males 1.

These findings highlight that maintaining or improving cardiovascular fitness can significantly impact the quality of life and independence as one ages. Regular intense physical activity, like cross-country skiing, can remarkably preserve cardiovascular health even into very advanced age 2.

For a general understanding, VO2 max refers to the maximum amount of oxygen that an individual can use during intense exercise. It's measured in milliliters per kilogram of body weight per minute. The test usually increases in difficulty until the individual can no longer keep up, thus establishing their VO2 max 3.
