: Thanks Frank , wuff there is somebody who gets the sme thinking going. : There is a certain amount of " Lactate tolerance " resp. enzymatic and buffer capacity : the body is able to improve , but with very limited effect in a long race like 15 min and longer. A person with a plastic bag over the head is not able to run for very long. As Frank pointed out in some good posts before. Oxygen is the limiting factor off endurance. So to improve in an area where you measure progress in seconds does not pay out , if you can improve in area , where progress will be in minutes. : Problem , the minutes improvement is often a structural improvement and needs time and comittment. See capillarisation and so on. : As we learnd , diffusion is in healty person given . I can try to improve the surface , where the difussion takes place. ( Filling up the whole lungs. We see in beginners , that the apical lung areas are often not good used. On the other side we see in altitude , that the bloddcirculation is increased and the apical areas are getting better involved. : You can improve the piping system ( blood vessels moving blood to the muscles, you can increase the transportation system , more red blood cells and so on, but you have only so much oxygen . : Free deep divers are showing nice that you may be able with some changes in HR and other adaptations ( breathing muscle strength ) to be able to go longer without breathing ( up to 8 min is the world record now ) but thats extreme and a small group are doing this. : As Frank points out , people with a " better lactate tolerance " may only or are in much better " shape " in the way , that they are 1. metabolize better 2. produce less 3. produce different 4. have different muscle fiber % , have more hemoglobin and so on. 5. have a better coordination to use more muscle groups to push the same wattage ( like a power crank user , and therefor not load as much on one single muscle , but use a good team of muscles. : With a good team of muscles you may now still overload the weakest member , but the stonger once , which are not working on their limit actually will help to clean up the mess produced by the weak guy. ( Optimal recycling of the produced lactate. ) : I like to give one example here why extreme hard training may not really help lactate tolerance , but is more a question how you gut it out as Frank points it out, and how good in this extreme situation the athlete may be able to use helpers ( muscle they nearly can do the job , but not as good as the boss. : Example : 4oo m runner. : You have the picture over the first 100 m. Long movements nice power , dynamic picture. : time 11 - 13 sec. Over 100 - 200 meter the athletes seems to " settle " in and the good once are " rolling nicely. : Time 22 - 28 sec. : Remember energy supply. : 200 - 300 meter : the start to get a kind of more upright , they start to work somewhat more , they look not as smooth any more. : Could it be the acid pile up in the main motion muscles like hip extensor ( Gluteaus group , ) are getting hit hard . You may loose some muscle fibers because of acid situation ( EMG drops. ) : Last 100 meter is very often a " bad " picture . The runners are sometimes leaning back the arms are moving not as nice anymore . everthing locks tight. Could it be that nearly all muscle groups , who would do a nice job are actuall out more or less because of the acid situation. Some helper now , like hamstrings will take over hip extension , or the pectineus as an adductor but also as a helper for hipflexion is getting called to do a job as good as possible. : So this athlete has a limit physiologically how much acid he can tolerate. Everthing above will shut his involved muscle down. ( protection from too low PH )But because of " hard training " he learned to compensate and can use some helper . : My observation over years with track and field injuries in anaerobic distances is , that I believe the extreme " lactate tolerance training" actually not improves the acid ability , but it is overloading ,due to wrong motion pattern a lot of mechanical structures. : One as an example is the achilles tendon. : In running you have a slightly external rotation at the end of you take of. With spikes and an overload of acid gluteal situation , you start to use more gluteaus medius as an extension , but also external rotation muscle. More rotation , more twist in the achilles tendon , and so on. : Similar in biking and overload of patellar tendon. : If we have people with patellar tendon problem and they go on PC the pain is most immediatly gone, because of another muscle pattern. : Some things to think and we can discuss this even more
