The Muscular System

The Muscular System is a rather complex system that is responbible for movement. In my opinion, it is the most important right next to the nervous, skeletal, and cardiovasular system. As a matter of fact, these three work together, which I will soon explain. You see, the muscular system is filled with muscle. Muscles are long slender cells of fiber that compact upon demand. The nervous system sends electrocal nerve impulses to the muscle fiber which causes them to contract. In other words, the brain send messages to the muscle which in term, causes them to shorten. There are voluntary and involuntary muscles. Voluntary muscles are those of the respritory and urinary system. You can choose to breathe or not and hold your urine. However, involuntary muscles are those of the digestive system and cardiac muscles.

The skeleton provides you with firm structure and skeletal muscles have bones on them that pull on muscle.These are known as tendons. This acts as a lever that allows you to rotate the limbs.

Muscle grow in size and strength through exercise. Exercise=muscular hypertrophy=stronger muscles which able you better proficency in a sport. The types of exercises are strength training (calisthenics), resistence training (elastic force upon muscle contraction), plyometrics (explosiveness of speed and power)and weight training (bulking of muscle mass). Any of these will be essential for overall health and athleticism. There are two different types of muscles. Fast twitch and slow twitch. Fast twitch muscles contract rather fast and can exert more force whereas slow twitch muscles contract slow, but are beneficial for endurance.

You can work your muscles in many different ways. Anaerobically and aorebically. Aeroebically is essensial for cardiac output and strengthen the heart building cardiovascular endurance. Anaerobically is without oxygen and the muscles rely on the body's stored energy, which causes a build up of lactic acid. for those who are unaware, lactic acid builds up in muscles when they are being exerted with high intesity resulting in a "pump". Muscular endurance and muscular strength are two different components of athleticism. muscular endurance is the muscles ability to continue a streesful activity without undergoing fatigue and muscular strength is the muscles ability to exert force. Muscular durability or muscular recovery is the ability of the muscles to quickly recover from and withstand pain.

Any amount of exercise wil strengthen and increase muscle mass.Even just 15-minutes of exercise will benefit your overall health. For me, a cross training of ressitence, strength and weight training are essential for health.

Superhuman or Immense Strength

Superhuman, above average strength, or immense strength is the ability of muscles to exert extraordinary force beyond human capabilities. This is often depicted in fiction but is also in real life. One can achieve this superhuman strength through adrenaline in which muscles contract beyond their normal ability thus can lift a higher amount of weight. There are also bodybuilders and athletes who have "above average strength". For example, an athlete can exert ten times more force then an ordinary person who does not engage in exercise.
