Marathon season is almost in full swing, and those of you training for fall marathons are probably doing long runs in the mid to upper teens at this point. I find the most common question I get from endurance athletes relates to the traditional pasta dinner the night before a marathon. For one thing, does it really increase performance?
I thought I would share my knowledge and experience on carbo-loading, whether it is just tradition, or if it really does offer the performance benefits sought by many athletes. Furthermore, now that there are so many different types of pastas on the market, I wanted to give you the low down on what may be best for your individual needs.
To lay the foundation, I define carbo-loading as increasing your intake of carbohydrates so that muscle glycogen is maximized, which boosts endurance for distance.
Healthy Runner’s Diet – Carbohydrate Loading Defined
The traditional method of “carbo-loading” involves a stage of prolonged exercise and an exceedingly restrictive diet called depletion, which is then followed by intense carbohydrate loading. More recent research suggests that intense exercise during depletion followed by excessive glycogen storage could lead to muscle trauma. This in fact would impair the storage of glycogen rather than enhance it. Other side effects that follow this method include bloating, added pounds, which not only causes you to feel drained and uncomfortable, but also increases injury risks. Personal records could be compromised under these conditions.
A more modified approach would begin a carbo loading regimen one week prior to the event, by tapering training mileage and shifting more of your total calories to carbohydrates, decreasing the amount of fat and protein as the week progresses. In other words, two days prior to your endurance event, you will not be eating mostly carbs and very little fat and protein. Carbo loading means simply shifting the percentage of the macronutrients to a higher carb intake. It does NOT mean load up on every carbohydrate you can lay your hands on. The reason this modified approach works is because the tapering in exercise simultaneous to an increase in carbohydrates boosts glycogen storage as effectively as depletion and loading, but without the negative side effects.
So to answer the question whether the pasta dinner the night before is optimal or not Continue Reading »
