That's correct. CV intervals start with the first one at 88-90% at the end, and then after 2-3 reps you reach around 92-94% HR at the end of the reps.
But do you really think it's possible to test the effect of training like that? The study is useless. Tinman believes in individualizing training based on FT- and ST-fibers, this study puts all athletes in the same boat. Also, long intervals are prescribed as "1000-2000m at 90-95% HRMax" - there is a HUGE difference between 6x1k at CV and 6x2k at CV. There is also a difference between 5x2k at 95% HRMax and 4xMile at 90% HRMax.
HR depends on at least a dozen different factors, so it should never be part of such a test anyway.
We have to consider that:
- Humans are individual. What one human responds to very well, might be a performance loss for someone else (let some of the current US elites try Jim Ryuns training for some time and they would all be toast after just a few weeks). They did not even separate between fast-twitch and slow-twitch runners in this test, which could be easily done by a muscle biopsy.
- The ranges are far too wide in the test. "Short intervals (between 200 and1,000 m long and from 95 to 100% of maximum heart rate[HRmax] in intensity)" - is this a joke? There is a huge difference between 200m and 1,000m repeats and the pace they are being done at. Also, some of the most intense sessions like 3x5x200 or 8x400 at 800m (mile) pace or faster will never reach close to that max HR. Let an elite do 8x400 in 59s with long rest and I guarantee you he will NOT get above 84-87% of his max HR at any rep. The aerobic system simply can't get up to maximum capacity that quickly.
- There are several external factors affecting running performance. What if an athlete improved nutrition? What if he lost weight? What if he gets more sleep? What if he is doing more strength/core now?
This study doesn't account for many factors and is therefore not very useful. I think discussing optimal training is very important and there have been great advances by coaches like Tinman or even here on the forums with Canova and Hadd/Cabral. We can learn much more from them coaching and training actual elite athletes than from a silly scientific paper that is trying to dumb down the complexity of running and make it very one-dimensional.
