Some interesting facts on how a bodybuilder converts his mucles into steel

WHEN A PERSON STARTS DOING SOME EXERCISE LIKE JOGGING,CYCLING OR SWIMMING, THE MUSCLES START UTILIZING ENERGY.INORDER TO HAVE QUICK ENERGY DURING THE FIRST FEW MINUTES,THE MUSCLES BURN GLYCOGEN STORED IN THEM.

DURING THIS PERIOD, FAT IS NOT BURNT!

ONLY GLYCOGEN IS BURNT & IT IS BURNT WITHOUT USING OXYGEN.THIS IS CALLED ANAEROBIC METABOLISM.LACTIC ACID IS PRODUCED DURING THIS PERIOD.PRESENCE OF LACTIC ACID CAUSES SOME SORT OF BURNING SENSATION IN THE MUSCLES PARTICULARLY THE MUSCLES OF ARMS,LEGS & BACK.THE MUSCLES BURN ALL THE MUSCLE GLYCOGEN WITHIN 3-5min.IF THE PERSON CONTINUES THE EXERCISE BEYOND THIS,LIVER STORED GLYCOGEN IS CONVERTED INTO GLUCOSE,WHICH IS TRANSPORTED TO MUSCLES THROUGH BLOOD.NOW THE BODY MOVES INTO AEROBIC METABOLISM.

THE GLUCOSE OBTAINED FROM LIVER IS BURNT IN THE PRESENCE OF OXYGEN.NO MORE LACTIC ACID IS PRODUCED!SO,THE BURNING SENSATION DISAPPEARS!PROPER BREATHING IS ESSENTIAL DURING THIS PERIOD SO THAT ADEQUATE OXYGEN IS SUPPLIED TO THE MUSCLES TO EXTRACT THE ENERGY FROM GLUCOSE.


THE SUPPLY OF GLUCOSE FROM LIVER IN COMBINATION WITH ADEQUATE AVAILABILITY OF OXYGEN ALLOWS THE PERSON TO CONTINUE THE EXERCISE.THE UTILIZATION OF ALL THE LIVER STORED GLYCOGEN IS COMPLETED BY ABOUT 20min.IF THE EXERCISE IS CONTINUED BEYOND THIS ,THE BODY STARTS UTILIZING THE FAT.THE STORED FAT CALLED "BODY FAT" IS CONVERTED INTO CARBOHYDRATE ,WHICH IS UTILIZED BY THE MUSCLES.

THIS ALLOWS THE PERSON TO DO THE EXERCISE FOR A LONGER PERIOD!
