Hi Ian,

I’ve been looking and haven’t found anything on power lifting etc, but where skills are closely balanced, or possibly exceeded by the demands of the sport, it seems highly likely. I don’t think the length of time should matter. Freedivers frequently experience flow, and may ‘only’ be breath-holding for a couple of minutes. It can also be found in non sporting contexts, watching children play, they seem to access it incredibly easily.

Regards
