Running economy.Just like getting the best value out of a dollar, improved running economy means you're getting the most out of the oxygen you use. Running economy refers to using a lower percentage of your VO2max at any given pace and it's one of the benefits you get from good training habits. The more you run, the more efficient your body learns to be, not only on a cardiovascular level but in running form as well. As you become more experienced your body makes subtle adaptations that conserve energy. You tend to find your optimal stride length stride length Biomechanics The distance between 2 successive placements of the same foot, consisting of 2 step lengths; SL measured between successive positions of the left foot is always the same as that measured by the right foot, unless the subject is walking in a curve , reduce needless up and down motions, and relax your upper body. The bottom line is a smoother, more economical running style that spares oxygen demands. Although there are loads of variables that affect running economy including plenty that you have no control over--such as percentage of slow twitch twitch (twich) a brief, contractile response of a skeletal muscle elicited by a single maximal volley of impulses in the neurons supplying it. twitch v. 1. versus fast twitch muscle fibers as well as the structure of your skeleton--it is widely recognized that training improves economy within your own particular limitations. Gradually increasing the mileage MILEAGE. A compensation allowed by law to officers, for their trouble and expenses in travelling on public business. 2. The mileage allowed to members of congress, is eight dollars for every twenty miles of estimated distance, by the most usual roads, from his of long runs and running fast intervals can help you improve your running economy.
