… I’m curious about a 6x1k (treadmill) running session today – specifically the tHb reaction on the 5th interval.
Laps 1&2 are the warmup 3,5,7,9,11,13 are 1k intervals at a hard pace (slightly increasing from 1-3, 4th and 5th same as 3 but “broke” during the 5th and jogged to the end. 6th hard but much slower than the others)

… This is my main query – is this simply a cardiac/respiratory limitation that needs training (or just resting away from night shifts!). Or are there alternative explanations? On nights my nutrition goes a bit messy so I was wondering if you’d see something similar if I’d burned up too much glucose on the first four intervals. Alternatively could this just relate to muscle recruitment?

* for better interpretation it is useful to also plot HR
* I do not see any ventilatory limitation
– smo2 keeps returning + getting higher that previous value, also higher than basal
(starting) smo2, the slower recovery is perhaps caused by motion of measured muscle
group during recovery
– to clearly see ventilatory limitation during recovery it is neccessary to avoid any motion
of measured musle group.
* Lap 11 – in the middle of the bout you achieved arterial muscle occlusion, your cardiac
output was not high enough to overcome the sum of pressure in the muscle capilaries (the
venous outflow was not impacted as you do NOT see elevation on HHb )
– reason for that: harder to guess without HR trend, but either cardiovascular limitation or
muscle exhaustion leading to recruitment of more motor units (but due to lower
desaturation not very probable)
* Lap 12, 13 complete loss of ability to sustain or recover homeostasis

Conclusion: cardiovascular limitation, training should had been stopped after lap 9, futher bouts only led to “cardivascular catastrophe” and if applied repeatedly may lead to overtraining.
