Dear Jeff: Even though exercise is not your main area of expertise, I hope you are still willing to dispense some advice on this: What is the best method for osteoporosis prevention?
The general recommendation seems to be that strength training is the most effective measure, yet there is no consensus on the specific training parameters that are to be employed:
On the one hand, there's the idea that in order to have best results, it is necessary to expose the bones to multiple times bodyweight axial loading - this would mean doing either plyometric exercises or using very high resistance. For several years, a kind of "bio hack" of this kind has been offered by a chain of gyms called "Osteostrong": https://www.youtube.com/watch?v=eaoDswLQKjw
On the other hand, there's the theory that it's the muscles which signal the bones to grow, and in order to trigger this signal it basically suffices to push them near failure, almost regardless of the degree of resistance they are exposed to. That would mean that also lighter training (e. g. calisthenics drills such as free squats or tabletop pushups) could be effective, as long as all sets are taken to near failure. There is also some questioning going on whether the concept put forward by Osteostrong is truly legit, and not just mere marketing hype: https://www.youtube.com/watch?v=I3C2QY5Rogs
Both theories seem somewhat convincing to me, and both are probably somewhat effective. But since both concepts are almost contradictory, I would really like to know whether at this point there is one that seems clearly superior according to the current state of knowledge.
Can you shed some light on this? Your input would be greatly appreciated!
