The idea that the kids in the placebo group had to do ~4 months of base only to get smoked by the weight trained group in the final TT kinda makes me think this study is bordering on unethical.
I’d be pretty satisfied with a BASE training period that improved my 45min TT performance by 8%. That’s pretty good for a group of kids sitting at ~312W already. And all they had to do to achieve those gains were four exercises: knee extensions, inclined leg press, hamstring curls, and heel raises. That’s it. Maybe not the best exercise selection but, honestly, exercise selection doesn’t seem to make much difference in these strength training studies…as long as it’s some steady progression in a lower body exercise it seems to be good for a +7% or +8% gain.
That’s a lot for what were already pretty highly trained athletes. +25W. During base training.
