[b]Many on here will power clean pretty heavily, and some world class coaches have their athletes power clean for multiple sets of doubles and singles in the 90% range, however I have never heard of any track coach who has had athletes squat or power clean to max multiple times per week[/b]
They’re world class track coaches NOT world class STRENGTH coaches. Most track coaches are still utilising largely dated training methods. Malcom Arnold, for example, still stays loyal to the old ‘pyramid’ loading system.
Periodisation, as most understand it, is a dated concept within elite strength circles.
Many track coaches understand strength training as well as they do all other aspects of training. In fact, I would argue they understand much better than most strength coaches because they understand how to integrate weights into a training program for a track athlete. Especially the successful ones. They do not need plyometric coaches or overhead back throw coaches. They do not need strength coaches. Weights is such a small part and I know of more track coaches that DO NOT do pyramid weights than who do. If anyone around here does anything resembling a pyramid it would be something like 5,4,3,2 and all sets would leave a rep or two to spare. Getting strong enough to be great at track is easy and is not a big deal. Absolute strength is not what limits the great track athletes from the non-great track athletes. Carl Lewis, Oba Thompson, Kim Collins, Bolt, Lemaitre, all weak as kittens, all way faster than anyone on this board.
Call it periodisation call it whatever you want all programs go from less specific and more volume to more specific and less volume. That is common to all track training approaches. That is even common to the Bulgarian weightlifting program you reference. The things I have read from actual Bulgarians showed that they will use more volume, less intensity and even power variations and move toward more volume, higher intensity and less variation.
