The body is made up two kinds of muscle fibers. Fast twitch and slow twitch The average person has about 50% fast twitch and 50% slow twitch muscle fibers. Advanced athletes have about 70% fast twitch and 30% slow twitch muscle fibers. Fast twitch fibers are 10 times faster than slow twitch fibers.

Slow twitch- these fibers are more efficient at using oxygen to generate more fuel, for extended muscle contractions over a long time Fast twitch- these fibers are much better at generating short bursts of strength or speed. They use anaerobic metabolism to create fuel. They fatigue quickly because no oxygen is being used. Fast Twitch Muscle FiberSlow Twitch Muscle Fiber

Force = mass x acceleration In football athletes can exert up to 3,000 pounds of force with a hit. While average people can only exert about 1,000 pounds of force. 02: :00

The average male has 18-24% body fat. Elite male athletes have 6-13% body fat. Some fat is needed in the body such as essential fat. The average in men is 2-5%.

Cardiovascular fitness – The ability of the heart and lungs to supply oxygen-rich blood to the working muscle tissues. Advanced athletes have better cardiovascular strength than average people. Lots of elite athletes gain cardiovascular strength by running for long amounts of time. It increases metabolism, which means they lose more body fat.

Athletes need more strength than the average person in order to perform at a higher level. The strength of the athlete, most of the time, depends on their weight. Male athletes, generally, bench press pounds. Now days, there is medication that makes you stronger faster and easier.

A steroid is one example of one of these medications. It has nothing to do with genetics. Genetics also has something to do with how elite an athlete can be. if your parents were good athletes than there is a good chance that you will be.

A lot of it has to do with genetics. It is sort of like evolution. There are artificial ways to become more advanced like steroids. Also advances in science have created new techniques and new training exercises.
