Abstract
Introduction: The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems include small numbers of runners within elderly categories and the advantage given to the lightest runners within each weight category. Purpose: To develop a 5K Handicap Model (5KH) for men and women based on the known independent contributions of age and body weight to 5K run performance. Methods: bining previously published empirical and theoretical findings, we developed a 5KH putes an adjusted run time based on the inputs of actual run time, age, and body weight. Results: The 5KH provides more handicapping precision with age and BW than the age-only World Association of Veteran Athletes (WAVA) model and can be adapted to other race distances. Furthermore, the metabolic penalty for excess weight is significantly greater than the associated handicap. Conclusion: The 5KH is the first such model based on the independent effects of age and weight; es the problems associated with age and weight categories; and may give older and heavier runners added incentive pete.
Disadvantages of Age and Body Weight (BW) Practices
BW: “Clydesdales”
()
Advantage goes to the lightest within each category
Can’pete against those in other age and BW categories
Lack of precision
AGE: WAVA Standards (/athletics/)
Does not account for BW
Based on world bests – undue influence of very petitors at the more elderly level
Distance Running and BW
VO2max (l/min)  Body Weight2/3 (Astrand ’86)
5K run speed  VO2max/BW (Nevill ’92)
Therefore, 5K run time  BW1/3 (Vanderburgh 95, Crowder 96)
