Hello everybody. 

Recenlty, we bough a Moxy Monitor with the idea to change the typical Lactate studio to check Training Zones, and be a bit disruptive with the new technology. 

At the moment, we don't have any bike with powermeter, so we are doing some tests with the treadmill, and we have tried the protocol of: 

  • Maximal and progressive test
  • Up speed every 30 seconds by 0.3 kms/h more. 


Wondering if the inflexion points after the small plato are coincident with the VT1 and VT2.

We have done only 2 tests, and want to try at least to 10 more before offering our test to find trainning zones. 

Instead of the 5-1-5, we are doing this one in running because is faster, and in 20min (excluding the warm-up) we can find the zones. 

Any ideas/suggestions to improve? Have anyone done a similar test to compare with Vo2/lactate? 



This one is from both subjects, only Smo2, only intervals and inverted.

This one is from only 1 subject, always in VL, and warming up 15 minutes before the test including some intervals, smo2 and Thb, plus recovery time (the last one were only the intervals).

Any thoughts/suggestions? 

Thanks in advanced!

Hi, I have a done similar ramp test too and what I notice is that the inflection points change depending on the load ramp rate.  However, I use HHb as my point of reference as this takes Thb into consideration and it easier to correlate with the load.
 
In my case, the "higher" the load ramp rate is, the least inflection points I see in my HHb.

I believe this might be due to systemic delays and the different activation rate of the energy systems. 

I personally use the ramp test (ramp needs to be 1hour+) to find my O2 training zones. 
  1. The load before the first inflection point is my recovery area as the O2 supply is greater than required. 
  2. The load between the two inflection points is the balance range
  3. The load after the second inflection range is the out of balance range

Note: Training zone interpretation only works if the training load change rate matches the ramp test results. 

As a cyclist, my test starts with a 5 minutes warm-up phase at 30% FTP then it ramps up linearly to 110% FTP .  So 30% to 110% in about one hour.

Thank you very much bobbyjobling

We are now working luckily in a laboratory with triathletes, we are doing incremental tests of 15 minutes. I can not modify the protocols because they are marked by the laboratory but we are observing that when we compare SMO2 and VO2, the VT1 and VT2 coincide with the inflection points of SM02 and hemoglobin. This week when they send me the results, I will share them.

I believe that in a long test of 1h is not valid, there are many factors that affect the results, muscle fibers fatigued, dehydration, low blood pressure, low levels of muscle glycogen, ....... etc

I have consulted and discussed with several physiologists and doctors, for that reason the protocol created with these arguments that should be:

A warm-up (10-15min) to activate all the systems (nervous, energetic, .....) + A break not very long (5min approx) + a protocol of 15-20min incremental ramp (not stepped)
Short intervals of (30-45 s) with small increments of speed (0.2 Km / h)
