I'm new to the concepts or rather terminology of anti-glycolytic training and how it might apply to the mitochondria. Pavel and Al Ciampa talk about the benefits of anti-glycolytic training. I wondered if someone could walk me through the following points / questions. 1. I always understood that it's best to spend a small proportion of time working out anaerobically and a larger part aerobically. For the Kenyan elite runners this translates to 20% anaerobic training and 80% aerobic. The bit in between -- say 75% - 89% HR max -- is best avoided. Does alactic training mentioned by Pavel and Al effectively mean anaerobic, while glycolytic means 'the bit in between' aerobic and anaerobic training? 2. It's therefore better to train briefly alactic and mainly aerobic? The OTM swings would generally do this, right? Providing one got their breath back. 3. Avoid glycolytic training. Is glycolytic training simply the range of roughly 75-89% HR max? Or is it more like going hard for 15 seconds then resting or 45 seconds, which is almost similar to Kenyan training: 25% of time hard / 75 % of time easy. 4. Now, this is the main question. I want to protect at all costs my mitochondria due to a mitrochondrial disease. Pavel and Al refer to the mitochondria a few times. As well as protecting my mitochondria I want to make them stronger, to have more, and to produce more energy, because that way I get better. What's the best way to train? Avoiding glycolytic training? OTM swings. Alactic bursts with mainly aerobic? So far as I understand from the blog posts S & S is anti-glycolytic (which is good), has some alactic (also good), but is not aerobic enough for the mitochondria (hence some posts recommend more aerobic or endurance strength programming for the SFG cert). Therefore, would something like this be best for the mitochondria: A Science-Based Plan to Prepare You for the SFG Level I and SFG Level II Or does any one have suggestions? I'd prefer to keep it to Swing and TGU if possible. But doing the TGU and the Swings on the same day like S & S wears me out -- probably due to mitochondria dysfunction. At the moment I'm on the old Program Minimum, but I'm not sure it's giving the aerobic / endurance strength that is being referred to for the mitochondria.
