Physiological assessments versus performance tests.
I like to give here some thoughts on our great discussion on duration of a test and step length and step increase.
With change in equipment from classical tools like VO2 and lactate to live feedback information like NIRS SEMG live cardiac feedback with physiolflow the questions comes up, whether it is time to review what we actually like to achieve with this ideas? To make it relative simple.
I look at 2 questions ?
1. Do I like to test performance and than use the test result as a feedback, on my quality and improvement of my training program.
As a sub question.
1.1 Do I use the new performance information and combine it with a calculator and some statistical result to go back to design a new program?
2. Do I do a physiological assessment to have feedback on where I optimal invest time as I find the current reason of a lack of progress or the reason why I made progress do to elimination of a limiter
2.1 Do I use the assessment results to than design a new training plan ?goal but use live feedback to stimulate the target systems rather than performance combined with hope that the calculate % will trigger the planned stimulation.
Or in other words. I know I have a delivery problem and the limiter is the respiration. I now can use any performance level from easy 100 watt to above FTP for cyclist and use the live feedback to see how I trigger and target respiration.
Or I use a % of the maximal wattage or the LT and hope the theory I have in a cook book really achieve the respiratory stimulation.
I can see it live versus I can hope for it ??
What I do :
Performance testing .
I test the performance. So a 400 m runner will do a 400 m run and I can see, whether my training ideas I started 3 month ago show a change in the 400 m run which is the sport the athlete likes to do. I have a figure skater and he or she will do a 3 min short program she or he likes to use for the upcoming season.
I retest this program and see, how after the triple combination the oxygenation as well the blood flow looks compare to a few month back.
I have a road racer main distances between 10 - 21 km.
I use a home stretch perhaps 13.452m 23 cm long . and use this as his test stretch under close to same conditions and take his time and at the same time get MOXY arm and leg feedback and than see what happened performance wise but as well a comparison in change in NIRS feedback and HR and if I have a BIO harness as well RF. I have a MTB athlete and a home course. So same there with additional feedback over certain section of the course like a uphill or a technical downhill or a flat or relative flat stretch . Time and physiological feedback .
This is a sport specific performance test or I do a race and this gives me objective feedback on change in actual performance. and a information what happened physiologically to try to explain the change in performance.
Can I use this information for future training ideas ?
Yes and no. The performance part no.
the physiological feedback yes.
So a VO2 max or peak test will give me a feedback whether I may have change performance on this test idea ?
The skating athlete doing a VO2 bike test. ?? why
The hockey player doing a VO2 or LT running test . Why ?
The MTB athlete doing a VO2 stationary bike test ? Why ?
Can I use a LT or VO2 max / peak test form a treadmill or bike to design an individual limiter targeted training program used in the field?
Well many hope and some may even believe it.
Well even the father of LT ideas G. Mader very early on showed that this does not work at all.
We talk 1985 the year where Brooks started to question lactate ideas.
Do we believe VO2 max lab test can be used for applications an training designs.
Not one of the big brains of the time believed this really. That's why they designed field test and use VO2 there. We talk 1928
Do we really believe a VO2 or LT test and LT findings can hold up in the field when done in a lab. ?
I am always surprised that the question comes up is NIRS a validated.
. Question back with what ? Next question. Is the VO2 max test or the LT test validated ?
There is no studies out there who can proof that the performance increase we see is due to using any method from LT to VO2 to FTP or NIRS use. What we can show with NIRS or physio flow or SEMG and as well with VO2 testing is , that we change some physiological systems either with a functional improvement or a structural change.
So do I like to have some physiological feedbacks .
If yes. What is the physiological demand of my athletes sport. Based on this I than create a assessment protocol.
If I like to get a feedback on delivery systems I need to design a protocol which allows the delivery system to actually be fully functional. There is no discussion on this anymore and even the big v brains in VO2 testing agree, that the step length to have a fully feedback on cardio and respiratory ability has to be at least 5 min , better longer.
Oxygen uptake during the first minutes of heavy muscular exercise

Oxygen uptake, heart rate, pulmonary ventilation, and blood lactic acid were studied in five subjects performing maximal work on a bicycle ergometer. After a 10-min warming up period work loads were varied so that exhaustion terminated exercise after about 2—8 min. Peak oxygen uptake and heart rate were practically identical (sd 3.1% and 3 beats/minute, respectively) in the experiments. The heavier the work was and the shorter the work time the higher became the pulmonary ventilation. (WHY ?)
There was a more rapid increase in the functions studied when the heaviest work loads were performed. It is concluded that aerobic capacity can be measured in a work test of from a few up to about 8 min duration, severity of work determining the actual work time necessary. Duration of work in studies of circulation and respiration during submaximal work should exceed 5 min.
Do you like to assess recovery ability as the endurance demand of the sport is not resistance e on fatigue but ability of recovery.Or is it a combination off both so an assessment for delivery and an assessment on utilization Or are we interested in actually feedback in load intensity, load duration. in between load recovery and so on. ?
Than we may look at actual metabolic options to maintain ATP levels.
Here a short inside view in how we structure that in our seminars.
TIP = question to find out Limiter , so cardiac limitation, respiratory limitation, muscular structural limitation ( mitochondria density capillarisation for example ), CNS limitation like inter and intramuscular coordination.
So there are certain needs to find this. '
a) duration of step length 5 plus minutes.
b ) sport specific so if possible in the field.
c) interruption ( not ending of a homeostasis.)
d) Start without warming up or preparation. What do I get from this.
1. Physiological feedbacks form what ever equipment I use to collect physiological data's.
Can I use this for planning of my future training ideas.
Do I need a performance feedback for this plan . No
If I use classical physiological parameters like VO2 and lactate.
Hard to train 16 ice hockey player all with a great K42b VO2 equipment. Or test blood every 4 - 8 min n 16 runners of a track club during an endurance run.
No if you have new technology so you have live HR RF and SmO2 thb information's. Can I use performance ye s and no.
Take cross-country skiing loads on different snow conditions.
Take running in the field not on a track with up and downs.
Take MTB in off road training camp.
Take rowing on an open lake. Well sometimes you may have optimal conditions
RIP and SIP are much easier to understand and the protocol will be very different.
Can you see the " zoning" yes there is one and we hate it.
using physiological feedbacks a found assessment zoning is only a guide line to see, whether you are above or below the assessed values but you adjust the zoning accordingly to the target physiological stimulation you have for this specific workout and day.
It may be a higher performance if you can us e performance or a lower performance, That's' why in skiing it is much easier as you have to look on current conditions and the zoning is only meaning full having a physiological target and no performance feedback.
There is an interesting Blogger out there . using an ice hockey RIP and convert a RIP assessment into a TIP information ,, than creates interestingly enough 4 zonings when doing a 3min step test.
That is great to see, that we are not the only people moving downwards form the classical a ideas of more zoning better program ?
Will be nice to see his case studys , because based on what we do since many years a 30 second all out test always creates a delivery limitation. . No different with a 90 second all out test. So because it is an interval sport using a RIP 30 seconds and because it is an endurance sport you "prolong " the data collection to 90 sseocnds does not change anything in the fact that you create a delivery limitatioin in any case so you can NOT find a delivery limiter when you rule out the participation of the delivery systems in the actions due to the protocol design.
Now page 2.
More later , when we look the promised VO2 cross country ski erg test somewhat closer .
