"Like a lot of Scandinavian coaches, he has been influenced by Verkhoshanski either directly, or indirectly from Vittori. This means that Alnes’ athletes follow a block schedule with lots of explosive weights and jumps/plyos central to their overall plan."
Put this into a 400 m training program used by Michael Johnson and you are there? Michael Johnson strangely didn't do squats or hurdle jumps as far as I have read. He did split jumps which work very well but is this the whole truth or did he do hill jumps as I believe, not only hill runs?
Verkhoshansky is interesting (>> Verkoshansky t-nation) with a 6 week program.
I hardly believe Warholm followed all of the 6 weeks pyramid program. It is based on 2 days/week for the respective muscle group. [week 1; "easy" up to ...3x(6x[65-70%]) & "harder" up to 3x([5x80%]) of max load. Progressive loading the first 4 weeks, week 5 more like week 2 and week 6 with one very easy daay aiming for top performance 100%+ training day. Which day of the week which is 'day 1' is of course indifferent.
* 6 weeks followed by 2 weeks rest from strength training with 2 transmission weeks with light to medium low rep strength training. Then new 6 weeks maybe with a pb and thereby new kilograms on each %-level. With training only the first 4 weeks the rest weeks can be cut down to 1 week and 1 transmission week.
I believe the full strength program for runners' training is counterproductive if mixed with a lot of other training 5-6 days/week with different types of plyo and running including the important rest day(s). Michael Johnson trained 5 days according to a source on Internet. Why not start in autumn with just the 'easy' days in the program for the next 6 weeks. Next time go for the 'heavy' day of the weeks only and do week 1-4 of Verkoshansky's program which nevertheless is up to 95%. I think this is smart for runners where the '1-4' weeks also can be compressed into 3 weeks, with the 4th week off with just 3 days of jogging/easy training.
Verkhoshansky start the pyramid training on 45% of max (10-12 reps) and increase from there to 55% (6-8 reps), etc. Why not skip the 45%? Instead, warm up with progressive sets from 20%-30%-40%-50% with just 4 reps/set. Then start on 55% with 6 reps. This save a set but it also save energy to add one extra of the heaviest sets with a very easy set on 40% and 8 reps in between the last and the added one. Introducing some contrast-training which can be developed more scientific for the heaviest sets.
However, running is a kind of plyo sport. Transmission of force on the tracks in an extremely short period of time. The force here is actually working from the ground and up...
