From a previous post, I mentioned that for every pound you lose, you shave off a two seconds off of your mile time. But, what is the best weight for your running regiment? As you know, every person has a different body type, but there is a standard of norm when it comes to having an efficient body weight. This involves, of course, proper dieting and keeping watch of your BMI. Typically, you want to keep your BMI between 18.5 and 24.9 to have a good edge when you are running. Anything beyond 30 is bad news for you. However, having significantly low BMI will do you no good. Not only does that not make you run more efficiently, but also it will seriously affect your health. A dangerously low BMI can cause some serious health complications. If you’re trying to make a fast run during a 5-K event, you may want to consider NOT having a low BMI. An extremely low BMI will make you slower and weaker, not necessarily stronger or faster. Also, striving for an extremely low BMI can cause some to develop anorexia, which we all know is dangerous and very unhealthy. Good speed, strength, and endurance rest heavily on a fit body with a healthy BMI. In fact, if you want to get a grasp of how much weight you want to lose to reach optimum running time, you might want to Google the “Flyer Handicap Calculator”. A physiologist named Paul Vanderburgh made several tests on himself involving weight loss and mile times. After collecting all the data, he created the Flyer Handicap Calculator to help other runners find their optimum weight for the time they want to run to reduce any unhealthy BMI drops. So check out this calculator to see what is the best weight for your optimal run. Also remember, sometimes a drastic weight loss isn’t the best solution.
