A common misconception is that all endurance athletes fit into the same mold, that in order to be serious about your sport you need to look like a pro. What you find when you look at the pro peleton is that there is a wide variety of body types present. Just because Chris Froome looks like a praying mantis on his bike doesn’t mean that a rider of similar stature will have the same ideal racing weight. Marcel Kittel is of a similar height but probably has about 40lbs on Froome. If Kittel had tried to drop that much weight he would probably wind up getting shelled out the back of his local club ride instead of being one of the top sprinters in the world. Forcing yourself into a target weight that is unnatural for your body type and build is not only unhealthy it can also rob you of training gains and cause your performance to suffer. When the body is chronically malnourished it is not getting the necessary nutrients to recover and rebuild from training. Resulting in little or no gain in fitness. Sometimes even a loss. Brad Huff is a professional rider who spent a couple years struggling to drop weight and actually wound up performing worse as his weight went down. Once his coach helped him figure out the problem he actually started the next season at a higher weight than he’d ever had before as a professional and his performance increased dramatically. That’s not to say small adjustments can’t be made to find an ideal racing weight but you’ve got to be smart about it. In order to lose weight at a healthy rate, knowing your Basal Metabolic Rate (BMR) is extremely helpful. BMR is the number of calories needed for basic body function. The number varies greatly from person to person and in order to get an accurate number you need to take a BMR test. BMR tests take about 45min to complete and are extremely easy. There are plenty of online calculators out there to guess your BMR but they are wildly inaccurate and can vary by hundreds of calories from one calculator to the next. When you’re looking at maintaining a 300-500 calories a day deficit for healthy weight loss, that kind of inaccuracy can really create problems. Armed with an accurate BMR you can track your energy expenditure from day to day using either a power meter or any number of algorithms that use, average heart rate, speed and elevation to calculate energy expenditure. Again, the more accurate the better. Where can you take a BMR test? Right here at Science of Speed! Do you have any questions regarding Diet and Nutrition?
