Hey Juerg and everyone…Happy New Years to everyone out there…a bit before Christmas I posted a question regarding how much work (or how little) do people think could result in racing at the elite level (provincially)…thinking back to the post now I realized that that would depend on each person and on a lot of the factors that Juerg talked about in his last post…I guess that I am interested in the following points that Juerg brought up:
“Control the individual intensity for the Mitochondria density development. Questions for the athlete is : Duration , what is too long , what is too short , Intensity . ( control over Glucose , P O 2 , ammonia , Lactate , wattage. ) What do I use and when.
Set up LBP stabilization training or if possible improvement.
Here we will compare the different athletes changes over the last period , what do they changed on their own , and how did this changed the result to the other athletes. ( % of A1 and A 2 training ratio ) A1 and A2 are both aerobic dominant training units but with different goals. ( FFA - Mitochondria / Gucose - Capillarisation / MCT / MCT 4 )”
I would love some definitions as to the A1 and A2 training units and if you have any studies that look at the duration and intensity of exercise that results in an increase in mitochondrial density and duration and intensity of exercise that results in an increase in capillarization…I understand that training will result in an increase of both of these, but to what extent does duration and intensity come into play…I remember an article written by Owen Anderson on his Peak Performance website describing research done by Holloszy and then Dudley indicating that after a certain point and increase in intensity was needed to further increase mitochondrial density…would an adjustment of training zones after a FACT test be enough to elicit this type of response…as far as I remember their research indicated the need for quite a high intensity…any comments on Dudley’s work or anything else comparable…I know that there probably won’t be any real hard recommendations coming from research, but research can give us ideas and options…thanks
