BACKGROUND: Age-related declines in sport performance are characteristic of all endurance and sprinting disciplines. However, it is not known if the mode of locomotion (i.e. swimming, cycling or running) influences the age-related decline in sport performance in sprinting and endurance events. METHODS: To examine the age-related decline in three different modes of locomotion (i.e. swimming, cycling and running) for endurance and sprint events, the world best performances achieved for males in the age-groups 18-39 years, 40-44 years, 45-49 years, 50-54 years, 55-59 years, 60-64 years, 65-69 years, 70-74 years, 75-79 years and 80-84 years, were compared in swimming (1500-m and 50-m), cycling (1-h and 200-m) and running (10-km and 100-m). Each performance was considered as an average speed (throughout the distance) and the age-related decline in performance was expressed as a percentage of the world record (regardless of age group) for that discipline. RESULTS: The results showed that the age-related decline in 1-h track cycling is less pronounced compared to 1500-m swimming and 10-km running after 60 years. In contrast, the age-related decline was similar among the three locomotion modes for the sprinting events. CONCLUSION: Our data show that the maintenance of high performance in cycling persists longer into old age than for running or swimming.
