Running Muscles

One of the important features of muscles is the amount you can change them with training. Once you start aerobic training exercises, the amount of capillary blood vessels gets increased in the muscles that are used. Enzymes are needed by the muscles to communicate to the mitochondria how the biochemical reactions should be carried out; these convert the fat and carbohydrates into energy. With regular training, the activity of the enzymes can be increased twice as much.

While running, the muscles that are used are of three types: primary, supporting, and auxiliary muscles. The running primary muscles include the quadriceps femoris, hamstring, gluteus maximus, iliosoas, and the calf muscle. The quadriceps is a group of muscles that consists of many muscles on the front part of the thigh. They include the rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius. The knee and hip joints are the two joints that are moved by the quadriceps. The running supporting muscles are the biceps brachii, upper abdominals, and lower abdominals. The biceps brachii also called biceps is a muscle present on the upper region of the arm that allows the rotation of the forearm and flexing of the elbow. As the efficiency of running is increased with a bent elbow, the biceps are useful. The upper abdominals consist of the muscles in the upper abdomen and the lower abdominals consist of muscles in the lower abdomen. Together the lower and upper abdominals provide support to the strength that a runner requires in maintaining a good posture. The auxiliary running muscles include the external intercostals muscles and internal intercostal muscles. The external intercostals are used in forced inhalation and the internal intercostals are used in forced exhalation.

Sprinting And Jogging Leg Muscles

For running, all the leg muscles are important, but when it comes to the sprinting muscles, the fast twitch fibers present in them are the key to increased power, speed, and strength. The fast twitch fibers provide the body with explosive strength and power enabling you to leap and sprint. If you want to jump higher or sprint faster, you will need to build the fast twitch fibers. When running, muscles not only in the legs but also in the abdominal area are given a thorough workout. By running faster, the oblique’s will be worked on which will build more abdominal muscle and provide a flat stomach. When jogging the same muscles are used as those used for running, albeit at a lesser intensity. Regular jogging helps develop the calf muscles, thigh and hip. By performing a regular aerobic workout like running or jogging and maintaining a healthy diet with plenty of fluids you can achieve young muscles no matter how old you are.
