The described alterations in physiological characteristics in master athletes lead to performance decrements, which in turn result in progressively greater race times (Figure  1). Figure  1). From M65 to M80, the best time increases by 10% per age group (Figure  1). For M85, a disproportional increase in race time can be observed (Figure  1).
