Similar theories wrote......"Both of them agreed on tapering to lessen the amount you run. (mileage and intensity) You do less repeats while keeingp the same recovery along with time. That is one problem with trying to increase intensity and more intervals at the end of a season."
Hmmmmm, gotta take issue with a perhaps not so minor point if one is actually trying to follow a Lydiard program. I was coached by a Lydiard disciple in the early '70s. He followed Lydiard's workouts closely. I later had the fortune to spend 3 days with Lydiard on two different occassions in the mid-70s where almost all we talked about was training.
Lydiard's intensity continued to rise as the volume fell. The intensity of his workouts definitely did not level out. His first book (I have forgotten the name of it) had training plans that were far more a reflection of what his athletes did in the early '60s than the plans in his later books. I think he, his co-writer, or running editors watered the plans down for the "masses" in the later books.
When I was in high school my coach had us do 2 miles of sprint/float 50s. This was a workout straight out of Lydiard's plans. We would sprint 50 meters (55 yards then), float the next 50 (not really slowing down, just not driving one's speed for that 50) for two miles. It was the hardest workout I have ever done, seen, or heard of. This was done about two weeks out from the big meet. It was so tough we coasted the next two weeks. Lydiard described this workout as "tieing everything together" (endurance, strength, speed, etc).
I have coached for thiry years and have never seen a person who could really handle this workout. Though I incorporate the sprint 50/float 50 sessions into my programs in the late season, they are for much shorter duration (rarely these days over 800 meters).
I had one woman who did a mile (not 1600) of 50/50 back in the '80s. Because one is truly sprinting at the start she went through a 1/4 mile at 63, was crying when she went by me at 3/4....and finished in 4:41. She rested two weeks and ran really well in a few summer meets overseas.
A minor tangent if you are still reading......Lydiard's hill session were also incredible. He really believed in bounding up hills....but the bounding was more vertically oriented so one would only move forward a foot to a foot and a half with each bound. He worked toward bounding continuously 800 meters uphill in one repetition with several reps ion one workout. This would take 10-13 minutes/repetition. Ten minutes or more of explosive endurance......does that satisfy the desire of the "Specific Adaption to Imposed Demand" rule?
