I don’t think you can simply subtract upper weights here, sprint day there, etc. That doesn’t make a lot of sense. Not to mention, most people are not going to be limited by in their training by “CNS” fatigue or better phrased by someone else “Non-Muscular Fatigue”, but by tendon/ligament, muscular, and even hormonal recovery. It is likely that lower body weights would be one of the first things cut or modified because of the fact they tax many of the same areas that sprints/plyos/throws/etc. do.
I agree, it does not make a lot of sense BUT the point I was trying to get at in dropping days was that it does, at least in my little world, happen and more than on the rare occasion [believe me I would love to coach only athletes that always show up, do exactly what is asked etc. etc. but for me, that is just not reality] so one has to compromise. The day itself may not be dropped but moved and that can lead to the entire week being re-arranged which in turn, can mean, somewhere something needs to be dropped simply because you run out of days to move things to.
No sarcasm intended and please don’t view this as crying but from what I have seen on this site, the athletes I coach simply don’t train like a lot of these discussions imply that others do. Classes get canceled so now there is suddenly a spot to train that was not available before or those same canceled classes get moved or an additional lab gets added so now that second speed session planned that week gets dropped or changed. Or you are dead from having to study the night before, or your ride/bus doesn’t show, or the space gets double booked and you get bounced or if you don’t work that extra shift you lose your regular shift as well and so can’t pay bills etc. etc. I get most of those reasons/excuses at least once a week from someone. YET, if you look at many of the training journals on this site, and certainly no offense here, there are gaps all over the place, so what happened on those days? It is completely different if someone just did not do an entry or if there was nothing to enter. And if there was nothing to enter, what happened to the training that was supposed to be done on those days? To me it also does not make a lot of sense to just continue on with whatever the next day was on the calendar. I know this sort of answers my own question but if any run day gets dropped it will be those Tempo days as accel/speed will be the last to be sacrificed for a sprinter.
The point I was trying to make re: dropping upper body was related to specificity. What I was saying is that if you have to drop some or all of either lower body or upper body and you can still reshuffle the week to allow for good rest, I would tend to drop the upper body work 1st as to me it is the least related to sprinting in terms of specificity. What you are saying, I believe, is that what should be dropped first in that same scenario is the lower body as the sprint/run work will effect the same areas. Does that not contradict “specificity”? And if it does, or seemingly does, how do you know what to change and when just because of the contradiction? Or is it not a contradiction?
