Chronobiology!
Chronobiologists study the effects of time on life processes. I read a review of a new book that looks at chronobiology and includes some interesting items that would seem to have some implications for orienteers:*
"Most of us are mentally sharpest some three hours after waking, when concentration and problem-solving abilities may be up to 30 percent better than at other times of day."
And,
"To set a personal speed record, try scheduling your run or swim for early evening, when your perception of exertion is low and your muscles are at their most powerful."
So, orienteers are sort of stuck. From a chronobiological perspective, your peak problem-solving and physical abilities don't correspond. Oh well.
I also came across the online Morningness-Eveningness Questionnaire. The questionnaire takes a few minutes. The test gives you a score on a scale of 18-86 (with low scores being more eveningness). I was rated a "moderate morning" person. That sounds about right.
I'd write a bit more, but if the online questionnaire is to be believed, the melatonin concentration of my saliva is heading towards 3 picograms per milliliter. I'd better get ready for that!
*The book is Sex Sleep Eat Drink Dream: A Day in the Life of Your Body by Jennifer Ackerman, reviewed by Kyla Dunn in today's NY Times.
