No worries. I take the blame for that because Rob sent me the finalized version before it went to print, for my review, and I should have caught the errors in translation.
We progress from alactic power (full recoveries) to alactic capacity (shorter recoveries) over the course of the spring and summer.
The rest intervals to not get progressively shorter, however. They simply go from full during power to play clock during capacity.
So the series method is used during capacity and is consistent with Verkhoshansky’s, and others, explanation of the associated parameters and I make the necessary adjustments that are necessary relative to game biodynamic/bioenergetic structure. The word ‘series’ also corresponds to series of plays ran during a game/practice that is familiar to players and coaches.
So 3 x (20yd x 6) during capacity would be 3 series of 6 repetitions of 20yds. 4-5 minutes rest between series and ~40sec rest between repetitions.
If you’re interested, this is all explained in detail in my lecture DVD that covers the training during the spring and summer off-seasons.
