Henley 1 Posted June 12, 2016 Posted June 12, 2016 Let’s say our subject is a competitive and experienced age grouper. (thus excluding the likes of Olympic racers and sedentary warriors).He cycles (outdoors or on IDT) at a heart rate which indicates an effort of just below anaerobic threshold.My question: assuming he consumes “adequate” race nutrition and hydrates optimally, for how long should he be able to cycle at that HR before energy depletion or muscle fatigue or cardio creep or whatever catches up on him. Let’s say it is in-season and he claims to be “quite fit currently”. In other words what would constitute “inadequate”, “average”, “excellent”And for a runner?OK, I know “it depends on …..” But take a guess. What is your personal endurance time??
King_Crispy Posted June 12, 2016 Posted June 12, 2016 What are you on about? Just ask a simple question and you'll get a simple answer
Pulse Posted June 12, 2016 Posted June 12, 2016 I don't think there is any real answer to this question... Well, he should be able to keep going until fatigue sets in, but then the question is what causes fatigue... Don't think there is any real answer to that either, but its probably the point at which your body can no longer maintain homeostasis for one/more of it's systems (e.g. energy supply, core temperature, muscle contractibility, electrolytes, dehydration, etc. etc. etc.); or rather the perception of the brain that one of these processes are no longer in homeostasis, and that continued physical activity at that level would lead to inevitable death. So the short answer... for as long as he wants to, or believes that he could.

We know that in a case of hypoglycaemia and/or dehydration, the governor is of physiological nature, but as for all those other inputs to total homeostasis, perhaps the mind controls that.We are being told that we should frequently train at levels just below anaerobic threshold, the purpose being to shift AT level up closer to VO2 max. Sure this easily for 10 minutes, 20 minutes …. but between this duration and infinity there is a cut-off.Ideal would be for that cut-off to be the duration of your static effort required for your race. In practical (triathlon) terms, this should be a 20km time trial, or 40, or 90, or 180

The examples you give wrt training is not to increase maximal time, but to increase the intensity at which you can do a set distance.If your idea is to train for maximal time/distance, then its a different ballgame
Barend de Arend Posted June 14, 2016 Posted June 14, 2016 Treshold is frequently meant to mean: what you can sustain for 1 hour. So "just below" means you'll last 61 minutes
V12man Posted June 14, 2016 Posted June 14, 2016 4 hours.... if it's just just below, otherwise 6....
nonky Posted June 14, 2016 Posted June 14, 2016 i know there's a public holiday but does it mean that Friday moved to Tuesday? or, did i miss the hub memo?
