OK Mike mad me feel guilty for sitting here reading without making a contribution, I think I actually made the first ever post on this board under the user name jacko.
I read with interest Dan's comments on short sprint work and aeobic and lactic power/capacity. Looking at the artcle kebba referenced though I see the protocol involved 30sec intervals and not the 10-40m type work dan used as an example.
I also wonder the effects on skill of pushing shorter recoveries on this type of work, eg this session from a recent presentation:
Acceleration Development (10-40m, with sets of 3 or 4 x
3-5 efforts in each set) use 1′ and 4′ recoveries; use
blocks, group starts, rollovers or fly-ins emphasize
mechanics, rhythm and relaxation – can add one to
two special speed endurance runs with 5′ recoveries
Multiple Jump Series: 5 x 5 hurdles at 33″ and 2m
spacing; dynamic or static to needs
Wt. Training: Olympic lifts, Presses, and Leg Series;
Ancillary lifts: Russian Twists and Negative Toe Risers
Cool Down with 5′ of jog/skip routines
Where did he reference an article? Can you provide the article or a link?
Regarding the Specific training session you lay out, I noticed the seemingly short rest as well and have heard that in reality Dan is not so anal about it to where he holds them to the exact interval. I’m sure it is something like a walkback, etc. You would think he would extend it were skill/quality to decrease.
Also, though the “rule” is 1min per 10m run, from what I have surmised Dan feels there are neuromuscular happenings that the shorter rest bring about and that he feels they are important. I don’t know what the neuromuscular things that he refers to are however.
