Scientists study 82-year-old with the body of a 20-year-old

Researchers say an 82-year-old Spanish runner, Juan López García, has the highest VO2 max recorded in an octogenarian and now competes in ultramarathons after taking up running in his mid-60s.

Scientists are studying an 82-year-old man from Toledo, Spain, whose aerobic fitness matches levels more typical of people in their 20s. Juan López García began running after retiring at 66, later started competing at 70 and now takes part in ultramarathons. Laboratory tests reported he has the highest VO2 max recorded in an octogenarian and that his muscles absorb and use oxygen effectively. The case has attracted international attention because it raises questions about how sharply physical performance must decline with age. Key findings: - Juan López García, 82, from Toledo, competes in ultramarathons and only began running after age 66, later starting to compete at about 70. - Laboratory testing found a VO2 max described as the highest recorded for someone in their 80s and noted unusually effective muscle oxygen use. - Other performance measures, including lactate threshold and running economy, were described as good but not extreme, which researchers say suggests training plays a major role. - López García typically runs about 40 miles a week outside race preparation and increases mileage before events; his routine includes long runs, interval sessions, and bodyweight strength work, and he follows a Mediterranean-style diet. - Scientists involved say the case challenges assumptions about ageing trajectories and has drawn sustained research interest. Summary: The case challenges common assumptions about how sharply physical capacity declines with age and has prompted international scientific interest. Tests show some physiological measures are extraordinary while others are within expected ranges, so researchers note consistent training may explain much of his performance. Undetermined at this time.
