the science behind mixed martial arts part 9

Quite right, the muscle pain you feel after a work out is infact some muscle tissue damage due to stress which allows the body to rebuild the muscle tissue making it larger or creating more density.

This pain is called "DOMS" if you google it you'll find out alot more. (Delayed onset muscle soreness).

your right about how they train but u have what they're training for mixed up they are training for overall body stamina. To last the 5 min rounds. Power and strength and mass building is done by increasing the weight lowering the reps. Most fighters are at the weight/strength they need to be so most MMA guys train for stamina. and in my eyes worry more about being in shape than fighting (eg lesnar no fighting skill beside wrestling but in incredible shape) Most fighters have poor stand up

" Originally, SEG trademarked The Octagon and prevented other mixed martial arts promotions from using the same type of cage, but in 2001, Zuffa gave its permission for other promotions to use octagonal cages (while reserving use of the name "Octagon"), reasoning that the young sport needed uniformity to continue to win official sanctioning."

interesting , i had no Idea.....but I dont think that is the reason this show did not use the octagonal cage.

ya i don't know either why they used this one, i haven't even seen one like this before in ufc.

not really my goal is 500 and i'm 15 but you must rest
