I’m happy my attempts at nuanced discussions on strength training made such a lasting impression because that was definitely not my podcast.
As far as I’m aware, strength training is only shown in the scientific literature to have power benefits across the board, and in your n=1 anecdata, if someone hasn’t been training properly on the bike. The big reason it helps untrained people is neural drive, which would be equally effective by doing proper on-bike training. For my n>100, strength training doesn’t do shit for most people’s power on the bike except for peak-1min and for a “super responder” (my phrase, blame me if it’s a bad one) we might see an improvement in the 5-30min range but that’s highly atypical and in line with the studies done on strength training, which typically don’t show an improvement in vo2max at all.
I guess you missed my purpose in including the Coyle study too, which is that the original question posed was on what are the physiological changes with an FTP increase. That study goes into many of the changes with improved endurance performance, but the other one not really mentioned (since they controlled for it) is vo2max which sets the upper limit for FTP.
One more thing, there’s no such thing as “glycolytic strength” since that system is a reaction to a rapidly dropping muscular energy state that can’t be covered aerobically. Improvements are actually due to reducing the feedback mechanisms that shut down contractile function during intense exercise.
