As I have read a little more about Igloi over the last couple days, I realized that I have likely misunderstood it a great deal, as it pertains to "swing."
Modern training is all about timing, when it comes to an interval. From what I understand, though, Igloi thought of it in terms of "style," i.e. form. If I am not wrong, he really wanted to watch for when form falls apart, due to fatigue. It's a different concept from thinking of doing 400m repeats until one isn't able to maintain the same pace.
When we run at 7 minute pace, our form is drastically different from mile pace, which is different than 100m pace etc. At what point does the form change, though?
I am hypothesizing that one can train for the "swing" of a race speed without actually running at race pace. In other words, maybe I run a 4:45 mile, but at 5:00 minute pace, my mechanics are almost identical. Maybe at 5:15 pace, the mechanics are also pretty close. So, maybe I can train for efficiency to support mile pace (specific endurance) by doing sets where, say, the first two reps are at 5:15 pace, and the third one is at mile pace. This is just an example of what I am trying to get at, maybe the times aren't correct.
Naturally, running slower may affect power, but I'm not really talking about that...anyways, it seems that Igloi made his runners do lots of fast strides at the end of workouts. What we are really talking about is running intervals where we are getting a lot of aerobic work, but are using the mechanics of racing.
Any thoughts on this? Am I completely wrong?
