The New York Times discovers Yale prof’s Age-Declining Tables
The story also talks about Mary Decker Slaney:
Sometimes, as with Mary Decker Slaney and Doriane Coleman, elite middle distance runners, the end of a career starts insidiously with an injury from which their aging bodies just cannot recover.
Slaney, who is 57, ruptured her posterior tibial tendon in 1997. She had surgery to have it reconstructed and then tried to train, telling herself she could get back to the point where she had been.
“For a long time, I thought there was still a way to get better,” Slaney said. “But eventually you get to a point where you realize that is not happening. I couldn’t run, I could only jog and to me that was disheartening. But after about 10 years, I decided: O.K. I will jog because I can’t do anything else.”
She was saved, she said, when she discovered a sort of combination of elliptical cross-trainer and bicycle that she can use on the roads outside her home in Eugene, Ore. “It is the closest thing to running without actually running,” she said. “I got on one for the first time and within 10 minutes I knew I had to have one. I thought, Oh my God, I haven’t felt that way in a long time.”
Slaney still dreams of running, and she often dreams she is back on the starting line. Her dreams even include training again. “There is nothing to replicate the feeling of running,” she said.

Well, that’s a little spooky. Best 200m time at 40 was 23.42. The table predicts 26.8 at age 63. Last month at Indoor Nationals three weeks shy of 63 I ran 26.83. Hummmm.

He didn’t know of existing age gradings? Or did he have the wish to calculate them on his own? A perfectly understandable wish.
I have a spreadsheet that can generate age gradings at any time, after whatever world record improvement. It unfortunately isn’t a straightforward data driven process, many choices have te be made. And so anyone comes up with a bit different gradings, although the main idea remains the same.

I can’t add pictures in this forum. I made a graph comparing Fair’s gradings, our official gradings and mine. Fair is more optimistic about decline than the others, that is, he thinks decline is less severe than the others think. From a certain age decline is accelerated and his is more pessimistic than the others, so he thinks acceleration will be very severe. I’ve done this only for 100m for men, other events will show the same pattern I guess.

I put in my age 45 400m time and it says I should be able to stay under 60 seconds until I am 69. I wish that were true.

There was nothing new on age grading in this NY Times article. In fact, the excellent NYT economics journalist David Leonhardt wrote an article on the same topic in 2003 that was far more insightful with more details on Prof. Fair and his work. You can find the original article on Prof. Fair’s website or on the NYT database. http://www.nytimes.com/2003/10/28/science/for-aging-runners-a-formula-makes-time-stand-still.html

I like it. Now I’ll test it out.

Here is Weia’s chart

Here’s description of chart:
Blue are the current world records for the men’s 100m, green WMA’s age gradings, red is my grading model and orange Ray Fair’s system. Vertical is (reverse) percentage of Bolt’s 100m record.
