xnfx, you started a great discussion mate.

Just to add some more in regards to your most recent posts.
Running and sprinting is a fine example and one that I often use when working with athletes or my most recently endevor, a team within the fire service. The demands of fire crew may well not be the same as a pro fighter but its alot more common than many people think.

In regards to specific training. Mayweather is a fantastic candidate. Mayweather has speed. Something he has utilised since his amateur days in lighter divisions. He has grown in weight but kept the speed he had, infact he seems to have increased it over time.

Going back to sprinting and distance running. Look at the athletes. In general the long distance runners are slight in muscular definition and raw power however their muscular endurance is alot stronger. A sprinter is another species all together. Built for power and shaped like a body builder (only real).

A 100 meter sprinter would usually rely on ATP (adenosine triphosphate). This is the source of muscular contractions like when you lift something heavy. As a fighter its used in sudden bursts with punches but when kicking its a full contraction. A long distance runner relys more on endurance depending on distance and running pace. Starting with part lactic and part aerobic "Oxygen for fuel" and as time goes on it turns to mainly oxygen. You will know the feeling of breathing heavier and sweating, they are the results of oxygen use as fuel.

For a fighter its great to be able to kick hard and fast but you need to be able to kick more than once or twice right. So logically training a muscle to be continuosly relying on fast twich fibres and power energy systems is not the answer. The key is both. If you like Buakao you will understand his raw speed and power in such dynamic kicks. In this upcoming K1Max he is first up against Sato. Now Sato is not a hard kicker or really fast either but he kicks alot. Seriously he took Kaoklai apart by peppering him with kicks constantly.

I suggest you look more into training all systems and at all times. Speed is best trained while fresh and not at all fatiuged thats simple and keep it so. Muscular endurance takes time to work on. So setting training for both, even intival work. Setting focus on one area is doom. Why concentrate on one specific area when your sport requires more.

Ok, all this talk about exercise has made me tied and its bedtime for me.
