Performance Declines Are Accelerated in the Oldest-Old Track and Field Athletes 80 to 94 Years of Age.

Physical performance declines with age, even in exercising, healthy individuals without major illnesses or orthopedic issues. The rate of performance decline is often reported to accelerate after the age of 70 years, but almost no data are available on performance in the fittest oldest-old. To assess their rate of decline in performance, the biggest data set of track and field athletes aged ≥80 years (1567 results) ever published was generated for different disciplines from German Athletics Federations including 1997-2019. Performance at age 80 years of athletes still participating at age 85 years was compared with those who discontinued. Only 1 of every 22 athletes competing at age 80 years still competed at age 90 years. The performance decline was more than three times as steep in athletes aged ≥80 years (on average 1.62%/year, men: 100 m, R = 0.31,
