This has been on my mind recently and wanted to ask a few times for input from John.
Many sports, no fixed training schedule, let them play and find out what they like, that was the default answer.
Seeing this new younger age athletes (cycling, swimming) not sure this is still the case.
These athletes must have had structured training and volume for years to perform like they do.
This interest me, supporting a few disadvantage children runners and just seeing what a change in diet can do to their performance.
This is going to sound strange, bear with me: I have asked a biokinetics if it is possible to take one of these children and turn them into world class athletes by structured training from a very young age, and he was not convinced it is possible.
