Sprints And Marathons: Increase speed and stamina in running

Lesson 1: The Basics

Sprints commonly are tested in track events including 100 m, 200 m or 400 m races. World-class athletes may finish these events in ten seconds, twenty seconds or forty-five seconds, respectively. A marathon is a race that's 26.2 miles long with world-class athletes completing the race in just over 2 hours.

Scientific research has demonstrated that sprinters and marathoners have predominantly different muscle fiber types. Sprinters will have fast-twitch muscle fibers that create greater force and bear a faster contraction or response time. Marathoners have slow-twitch muscle fibers that create force slowly and remain contracted longer.

A big amount of calories and energy are burned during marathons, calling for a significant energy source. To meet this requirement, fat, carbohydrates and protein supply the majority of the energy. Sprinting uses ATP or glucose as energy, as the total amount of energy burned up is lower than in marathons.

Sprinting is an anaerobic activity that lets the muscles contract without oxygen. These anaerobic activities are characterized by short acute bursts of energy utilizing a big percentage of maximal strength. Marathons are an aerobic activity that calls for oxygen to be delivered to the muscles during contractions. Aerobic activities call for a lower level of physical exertion over a longer time period utilizing a lower percentage of maximal strength.

Both sprinting and marathons may provide a number of physical advantages, including weight loss, improved heart, and cardiovascular health, expanded strength and endurance and increased bone density. Running likewise may have positive effects on mental health, including treatment of depression or curing addictions.
