The purpose of this study was to examine the sex and age-related differences in performance in a draft-legal ultra-cycling event.
Methods:
Age-related changes in performance across years were investigated in the 24-hour draft-legal cycling event held in Schotz, Switzerland, between 2000 and 2011 using multi-level regression analyses including age, repeated participation and environmental temperatures as co-variables.
Results:
For all finishers, the age of peak cycling performance decreased significantly (Ss = -0.273, p = 0.036) from 38 +/- 10 to 35 +/- 6 years in females but remained unchanged (Ss = -0.035, p = 0.906) at 41.0 +/- 10.3 years in males. For the annual fastest females and males, the age of peak cycling performance remained unchanged at 37.3 +/- 8.5 and 38.3 +/- 5.4 years, respectively.
For all female and male finishers, males improved significantly (Ss = 7.010, p = 0.006) the cycling distance from 497.8 +/- 219.6 km to 546.7 +/- 205.0 km whereas females (Ss = -0.085, p = 0.987) showed an unchanged performance of 593.7 +/- 132.3 km. The mean cycling distance achieved by the male winners of 960.5 +/- 51.9 km was significantly (p 0.05).
The sex difference in performance for the annual winners of 19.7 +/- 7.8% remained unchanged across years (p 0.05). The achieved cycling distance decreased in a curvilinear manner with advancing age.
There was a significant age effect (F = 28.4, p
Conclusion:
In this 24-h cycling draft-legal event, performance in females remained unchanged while their age of peak cycling performance decreased and performance in males improved while their age of peak cycling performance remained unchanged. The annual fastest females and males were 37.3 +/- 8.5 and 38.3 +/- 5.4 years old, respectively.
The sex difference for the fastest finishers was ~20%. It seems that women were not able to profit from drafting to improve their ultra-cycling performance.
