: Here now 3 examples of Lactate paradox. : Not a very good name ,I know , but it may explain it somehow. : Lactate paradox are lactate readings , where people think this is not possible , before they try to think somewhat more. Here 3 examples : : 1. You go on your bike from zero all out for 1 - 11/2 min. You stop and take a Lactate. : Reading perhaps 2.3 mmol/l : You go back on your bike because 4 mmol would be " anaerobic threshold " but even with going all out you not even reached 4 mmol/L : What's wrong. Now you think : let's measure again and after 4 min your Lactate is now 7.3 mmol. : What the heck is going on , you think and you take another reading to see the accuracy of the machine. : This is now about 6 - 7 min after the all out and about 2 - 3 min after your second reading. Your new reading is 9.3. : Oh ...... : Your kind of frustrated and about 6 - 10 min later you take one more and now it is 4.6. : Remember what we measure , : a marker what may have happened in a muscle and it takes some time ( more than a HR reaction ) to have the lactate ( some of the lactate ) on your finger tip or Ear lobe. You still do not know , how much got " lost " or used underway. So you only know you produced a "problem". : Think about this and the way some people measure lactate. : 2. Exellent example is actually rowing : : In rowing you have to start with an end sprint. ( surfing of the boat on the water , actually a lot of people do this in other sports too but not very successfully. In fact you may still have some coaches out there who tell their athletes just go all out abd one day you will be lucky and you can hang on the whole 2 hours. Problem of this is , that the coache is mostly already dead , when this happended and the athlete did the all out in a wheelchair race on a very steep downhill stretch). : Now again in rowing this is different because of the position of the boat in the water. : You have to go all out for a short time and you will be anaerobic. You actually may have 14 - 16 mmol ? l in the blood. You think you are not able to sustain this for very long. So what they have to do is to : " slow down" on an intensity , where the production of lactate and the " distruction " of lactate are just in a balance. ( which performance wise will be arround LBP wattage ). But if you measure the lactate it will stay more or less on 16 mmmol/l The don't add more to the problem , they just keep it under control. And try at the end to push for an endsprint. ( Mostly the competition is getting slower as well. That's one reason why in rowing your aerobic level ( mitochondria and capillarisation ) have to be unbelieveble good.If you think how long a race in rowing is , and how many hours they train than you wonder not any more why basic endurance training may make you faster. : The stupid logo of . To get faster you may have to go slower . : 3. Now this is a very interesting finding we had and started the whole discussion here. PC or power cranks. : The first PC I had from Frank I could lock. So we tried to push on the cranks above LBP so we would have some Lactate in the system. ( Which was at the beginning very easy , because the poor hipflexor would be dead very fast ) : Lactate in the moment we were close to dead was for example 5 .6 : Now we fixed the cranks to normal cranks ( 10 - 20 sec ) and kept going on the same wattage . This was actually possible . HR would drop and also Lactate and we would recover. How come ? : The limit was the hipflexor system , and once we got ride of them with normal pedals we could push the same wattage and lower the lactate , because the " old " technique at that time was still more efficient than the new. Resp The FACT test gave us the answer. : FACT LBP HR on power cranks was 145 : FACT LBP HR on normal pedal was 160 : That' s why we use Lactate and HR for this case. : In the follow up I will tell you why we check this. : Here a short hint : : Could it be , that an EMG may be helpful to get this idea going and what would we expect from something like this. : Would an overloaded Hipflexor group show up in any blood values like ammonia or urea.? : Let's see the rest of the story later.
