Getting "bike fit"

[kraven]

I wonder if this effect scales with chronological age?
That is, I wonder if subjects over, say, age 30 should have a smaller max interval or greater?

Very interesting.

A friend rides dirt bikes every weekend,yet he rides on quad trails and never stresses himself,then he comes here where we have "real"trails and hes gasping for air in 10 minutes. Doesnt comprehend momentum and the need to even be able to stand up and ride it like a dirtbike.

I guess there's differences in getting the body and mind ready for a hard dirt ride or Adventure ride. If you never push any limits you dont get much better/stronger. Just riding down a dirt/gravel road is no big deal,but doing it for a week straight at a good clip will wear you down if your out of practice.

You are referring to general cardiorespiratory fitness ("gasping for air"). Clearly his negular riding is not intense and/or frequent enough to develop his cardiorespiratory fitness. He needs to do some additional aerobic training or come riding with you more often.

However, this thread is about muscle soreness which is different from general fitness.

I am not aware of any research on the duration of the "repeated bout effect" in older subject. However, there is research showing that the "repeated bout effect" occurs in the elderly (e.g., http://onlinelibrary.wiley.com/doi/1...437.x/abstract) and it is not much different from that observed in younger individuals. So my educated guess is that duration of the effect is also similar.
