The test today consisted of first 1,5 km warm up (around 11 km/h), then after a short break I started out at 9,6 km/h, and increased the speed with 0,4 km/h each 2 minutes (I couldn't figure out to get the display show distance, so that I could have used my normal approach with increase each 200 m). The recording was done with my Garmin Forerunner 305 configured for data sampling each second. Here's the hrm profile:
One thing that stands out is the fact that the terminal pace was (only) 14 km/h and that at an HR of 171 bpm, close to my maximum HR. It was my judgement that I could not complete 2 minutes at 14,4 km/h though it somehow didn't feel as hard as 171 bpm normally does, the few time I've hit it in interval training.
The recovery for the first 30 seconds after I stopped the test was 30 bpm and thereafter another 29 bpm, with a total of 59 bpm within the first minute. After that i did a 5 min after jog at 9 km/h and look what happened, my HR just increased to the level of what should be app. 11 km/h! and even a walk at 5 km/h didn't send my HR below 100.
As usual the graph is not an clear cut ideal step wise flat curve, but my qualified measurement gave me these numbers, entered in the same spreadsheet as my previous Conconi running tests:
Transformed into a graph with Open Office Calc gives:
The test has once more proved not to be usable for the original idea, but as usual that won't prevent me from drawing my own conclusions.
As a little background info, I haven't been running much since April when I got an injury in my right Calf in a training pass (LSD) after at successful half-marathon.That surprisingly didn't hinder me in getting a new personal best it this years DHL-stafet with 22:10 for the 5 km, with an to my extremely high HR ending with 176 bpm.
The overall behavior is the same in all measurements, no clear tipping point. Overall the maximum speed is like the other tests except for the phenomenal one a year ago. The maximum HR is high. One thing that does seem different is that the slope, where the others seem parallel (same slope shifted left or right), this test shows a steeper slope, as if I've primarily lost ability to keep top speed.
what can i really use if for? - not much. Though I surely was in a better running condition last autumn and spring, it does seem as if plenty of other factors influence much, like for an example the10K I did last Sunday (48:25).
