I have heard of and have read many exercise physiology blog posts about hard-start VO2max intervals, but I recently came across the concept of the “hard-start FTP interval”.
For example, do 30 seconds to one minute at about 120 or 130% of FTP, then settle in for a further 12 minutes at between 95% and 100% FTP.
Obviously, there is much overlap (about 12 minutes worth in this example ) with the standard FTP intervals, but what incremental physiological adaptation would be pushed by this hard-start FTP interval, all else equal?
Would this be something that could improve lactate buffering and jamming it into the Krebs cycle?
“Mental” training for road race attacks where you have to go very hard but then settle into a pace that’s still not really sustainable?
Or would this maybe increase VO2max via a faster way of getting to the slow component?
