Abstract

Record running performances were compared between male and female athletes within an age range of 40–63 years and over events ranging in distance from 100 yards to the marathon. Curve fitting procedures indicated that age-performance relationships could be accurately expressed by use of an exponential model. Comparison of curve parameters revealed, a) that female performances declines more steeply with age than those of male athletes, b) decline with age was steeper for events beyond sprint distances than for sprint events for both sexes and, c) discrepancies between male and female performances did not relate significantly to event distance.

Résumé

Les performances de coureurs masculins et féminins âgés de 40 à 63 ans ont été comparées sur des distances allont du 100 mètres au marathon. Des procédures d'adaptation des courbes indiquent que le rapport âge-performance peut être exprimé avec exactitude à l'aide d'un modèle exponentiel. La comparaison des paramètres montre 1° que les performances féminines diminuent plus rapidement avec l'âge que celles des athlètes masculins, 2° le déclin qui accompagne l'âge est plus marqué chez les deux sexes pour les distances supérieures au sprint que pour les courtes distances, et 3° que l'écart entre les performances masculines et féminines n'est pas lié de façon significative à la distance.
