Wanted to add a thought about 2)...Couple of questions…
1) Miller which were the studies you looked at to see that training at longer muscle lengths trains all shorter muscle lengths too?
I found an aggregate study that says training at long muscle lengths are better for hypertrophy and carry over to dynamic exercise better than shorter lengths: Isometric training and long-term adaptations: Effects of muscle length, intensity, and intent: A systematic review - PubMed
2) Does anyone know - or can have a guess - what type of exercise isometrics is heart rate wise? Aerobic? The newer stuff Pavel talks about in S&S? I just notice that - even when breathing throughout - ISOs really get my heart rate up.
3) For the extreme iso guys here: If I was going to experiment with extreme isometrics what’s the best person / resource to look at to work out how to structure it?
Also, I upgraded to a WorldFit Iso-Trainer - better grip on handles, handles rotate and position better, thicker straps, easier to change length with the clasps. Recommend if anyone is in the market for a new trainer.
One more thing: I bought a crane scale, a bigger chopping board (leverage feels much better!) and a rolling pin… DIY 300 kg deadlift device / iso-chain alternative!
Will post some pics / thoughts after I’ve tried it out properly.
Also be interesting to see how crane scale readings translate to dynamic lifts if I get in a gym for a test at some point.
I think maybe isometrics could be a kind of alactic + aerobic (a+a) training?
I found this definition of a+a training in this article A + A Training – Be Well and Strong:
"In practice—what you do in the gym or your garage—is choose a high-powered movement and execute it with a purpose for 6-12 seconds, depending upon your current fitness. You then rest and recover for as long as is required so that you can again work at a high output."
This is basically what I've been doing with my isometrics - high effort of 10 to 20 seconds then Rest As Long As You Like RALAYL (not the greatest acronym
The article says the high effort = alactic
The recovery = aerobic
And that overall duration of session is very important (e.g. to aim for around 30 'repeats').
I've been doing 3 isometric movements (non movements?) - bent over row, overhead press and deadlift - 3 x 20 seconds.
So, 9 'repeats'.
If I was doing 10 second holds I'd do 5 to 6 x 10 seconds, which would be 15 to 18 'repeats'.
Still not 30, but getting up there.
I think Pavel's new book is going to be on this topic.
Any thoughts?
