Things I Don’t Understand About Speed

with one comment

1. Why is it that all the Olympian sprinters are jacked, while it seems that the fastest people at frisbee are skinny?

2. I recently read The Sports Gene. A great book that explores which parts of sports success come from genes and innate ability, which from training, and which from odd interactions of the two like genes which make training more effective. For sprint speed, the book generally comes down on the side of genes- success is about the amount of fast-twitch muscle fibers you are born with, backing up the old saying that “you can’t teach speed.” But while the book gave many answers, it left me with more questions. After all, it can’t literally be true that there is zero benefit to sprint training- or else why does anyone do it? I still have no idea how much speed a sprint training program would add. Would it cut 1 100th of a second of a 100-meter dash? One tenth? One full second? How different would the results be for someone who spent a year being moderately active, vs one who spent a year sitting on a couch? How different would the results be for people with different levels of “innate” ability, for instance different proportions of fast-twitch muscle fiber?

3. Have you ever run a timed 40-yd dash? Have you ever looked at NFL combine results? When I did, they blew my mind. I never thought I could keep up with NFL running backs or wide receivers, but I did think I could outrun a 330-pound offensive lineman. Not so, apparently- almost all of them can run a 40-yd dash in under 5.5 seconds.
