In an article entitled Train Slower to Race Faster in the most recent issue of American Track and Field, Clyde Hart suggests that 400 meter runners benefit greatly from “changing a small number of fast 150s, 200s or 300s into more repetitions at a slower pace with less rest…”
Hart says: "For example, three 200s in 23 seconds, you’ve got to take 5-10 minutes rest. But you can do six of them if you run them in 26 seconds, and you can take 90 seconds rest. Now what you’ve got from that is you’ve got twice the amount of running in and you cut the rest down, which is tremendous for conditioning. People say, “Yeah, but you gave up the speed.’ But we found that as you get stronger,your speed is enhanced.”
Hart says he developed this approach as a way to keep an oft-injured collegian Michael Johnson healthy for an entire season.
The article in its entirety is very interesting. I’m interested in reaction to the article/concept, especially as it applies to high school athletes.
