Recently I played around quite a lot with lactate and Moxy.
Moxy gives us advantage of seeing what is happening live, lactate provides single delayed reading.
In my trials I have noticed completely different results in lactate readings based on how well aerobic vs anaerobic systems are.
2 athletes, one triathlete 60min power about 310W, second athlete 60min power 307W road racer\Crit racer.
They both were told to ride 3x6min at their 60 min power with 4min easy spin in between.
While first athlete lactate was quite steady 3.7, 4.0, 4.0 second athlete was: 7.1, 4.5, 4.3
I think ideally to address both anaerobic and aerobic systems and largest population of athletes, we would need to ask them to do 2 separate tests (longer\easier, and shorter\harder), one for each system.
And even then we will have variations depending on how well trained particular person is.
For well train athlete 60 min ramp to is quite easy to do if we start at 30%, for somebody that is not trained, it might be very hard (right there indication of weak aerobic system?)
I don’t think there is one perfect “test” to do if we have diverse athlete population, as long as you are consistent and perform the test the same way on large enough population, you will learn how to read it and apply in to your training regime, then you will be able to judge based on current users all new users. It might be easier if you are working with single group of people eg: Triathletes, Track Racers, etc.
5-1-5 is quite good assessment it covers surprisingly a lot and it takes only 60 min, if you can’t spend 60min for test what is the point of training?
Creating training zones with Moxy and ramp might now work in daily training all the time in all cases (I was successful in many cases but also unsuccessful in quite a few).
I found day to day fitness variations might sometimes lead to workouts not finished the way they should be when controlled by power not Moxy
Here is completely not Moxy related example.
PowerTap P1 pedals, sometimes right pedal is missing and power is provided by left pedal only. Variations in L/R leg is 5% Left leg is weaker, I can’t complete some of the hard workouts, looking at Moxy only I can always complete them. For months I thought I just had a bad day…then Moxy showed me I’m working way too hard on those days.
I think we also need to ask the fundamental question, who our athletes are? How many hours a week do they train? What do they eat?
Somebody that trains 3 hours a week, will be training differently from someone that trains 12 or 24 hours.
Someone that trains 3-4 hours a week needs tests design to start so he will not get injured, performance gains are totally secondary in this case, he will get better regardless since he just started to train, injury prevention should be the main point in my opinion…, others that train 15-20 hours might need more than one test to really find out how to maximize their training time based on their goals.
Chase for “Sweet Spot” zone\s, is completely moving target.
