I found the article concise and easy to read, but I have a question that pertains to one of the points.
Realize I am paraphrasing but it indicates the the primary vehicle for increasing strength is in fact neural adaptations as opposed to hypertrophy.
During the first few weeks to possibly months, yes.
Lucy_Aspenwind said:Now is this strictly the case for weightlifting or would the same be said of a dedicated sprint training program on the bike? IOW, the gains from sprint training on the bike would be primarily from neural gains rather than hypertrophy. Si? No? 🙂
The reason that neural adaptations dominate the early going is largely a matter of timing...the nervous system is quite "plastic" and can adapt quickly to changes in demands, whereas it takes time for significant hypertrophy to be produced. In that regard, it doesn't really matter whether you're talking lifting or sprinting, you'd expect a similar initial time course (see, e.g., the track powermeter presentation that is available in the downloads section at www.fixedgearfever.com for data showing the rapidity with which increases in maximal power can occur). Where the two are likely to differ is going to be beyond that point, as the forces generated while cycling are generally quite a bit lower than those generated during lifting, and absolute force seems to play a role in inducing hypertrophy. (IOW, it's going to be easier to grow big muscles by lifting weights than by pedaling, even if you do a lot of standing starts, etc.) For this reason, it makes perfect sense to include a significant amount of gym work in the program of a non-endurance track racer, just as it makes perfect sense for a road racer to never go near the place. In my mind, the real question is what to do about the points race/criterium specialist whose forte is sprinting, i.e., how much (if any) gym work should be part of their program? On that point, I would go with "it depends", e.g., on where they live (can they ride all winter?), what do they like to do, do they ride for a team that can provide a strong lead-out or are they going to have to freelance the sprints, etc.
Lucy_Aspenwind said:EDIT: I have seen discussions on this form related to how quickly different systems detrain (FTP vs. Vo2max vs. AWC) - is there any information on NM power? Does it also detrain? And if so, how does it compare to the other systems?
To quote Szent-Gyorgi: "living systems are developed by activity and worn out by disuse." Other than that, I don't think it is possible to draw any strong conclusions about how various abilities respond to detraining.
