- Tables and charts illustrating the decline in athletic
- performance with age always leave me with the impression that
- aging is a smooth, gradual, and quite predictable process. On the
- other hand, considerable anecdotal experience gained by observing
- my running buddies and myself suggests just the opposite -- that
- one ages in "spurts," with long periods of almost imperceptible
- decline punctuated by sudden unmistakable dips in performance.
- The mechanism often is some kind of layoff, caused perhaps by
- illness or injury, after which one never quite returns to the
- previous level.
-
- Now mind you, almost all of my evidence comes from listening to
- the whining that goes on before workouts and before and after
- races; nevertheless, the phenomenon _could_ be real and still be
- missed by the averaging processes used to produce most charts and
- tables. If different individual's "dips" tended to happen at
- different times (i.e., at random), then these would
- get averaged out when many different people's performance records
- were included. Ironically, the carefully assembled data could
- give a very misleading impression.
-
- Surely there are statistical tests designed to settle this
- question. Does anyone know of any published studies? Can others
- confirm or deny this phenomenon with their own anecdotal
- evidence? (If there are a number of responses by email I will
- summarize for the net.)
