Do short burst cycling intervals, letâ€™s say 15 sec, 30 sec, 1 min on/ off (or even shorter off than the work period) have a place in sprint triathlon? Or any triathlon training?
I know Coggan more subscribes to longer intervals (eg 4mins) or atleast intervals which if they are short, have a shorter rest period to illicit a v02 max type or response. Or something similar I apologise if I have this incorrect.
On the other side of the coin you have people like Friel, wattkg.com which subscribe to short v02 max intervals (eg 30 on/off) which is argued can actually increase ftp, 40k tt times etc.
Does anyone swing either way or have input particularly to the shorter duration intervals? Would they be handy for sprint tris perhaps but not long course? If so, at what stage of your season do you perform these workouts (eg late or early in the build, in season or even offseason)?
Sorry if this has been done.
