Train Smart, Eat Right
Posted January 30, 2019
We like to assume that increased training translates to better health and, thus, more energy. However, when we increase training for a long race, we are sometimes left feeling lethargic, instead of more energized.
For many, proper nutrition throughout hard training is an afterthought. Eating well during your training cycle, not just on race day, is key to optimal performance.
When you increase your training, your body’s metabolism changes. The length, intensity and terrain of your runs are the influencers of your energy needs. In addition to running time, running intensity (think effort) has also been shown to increase excess post-exercise oxygen consumption (EPOC), which can cause an increase in metabolism. What does this mean? For most runners, it means upping your caloric intake of the right foods, at the right times.
As a general approach, aim for eating at least three meals and two snacks throughout the day focusing on whole foods. On days that you workout at a higher intensity, on more difficult terrain or for a longer period of time, you should focus on higher caloric foods, such as nut butters, avocado, granola, yogurt and potatoes.
Macronutrients, otherwise known as carbohydrates, fats and proteins, are utilized in different amounts depending on the type of training run you are doing.
At a moderate run pace, you are typically burning equal amounts of carbohydrate and fat. As the intensity of the run increases (either because of length or effort), your body reaches a point where it starts to need quicker sources of energy, and it burns more carbohydrate. Throughout all intensities, protein use remains relatively low but consistent.
Your body stores carbohydrates in the liver and muscles in a form called glycogen. Throughout exercise, your body uses the glycogen, and depending on the running pace, will go through glycogen stores (as long as they are full) anywhere from 90 minutes to three hours after.
Keeping this in mind on workout days and long-run days, you’ll want to increase your carbohydrate consumption post run, in order to replenish glycogen stores. In particular, your muscles are most primed to take up carbohydrates up to four hours after a run, so taking advantage of this replenishment window is key to proper recovery. Consider a post-run snack of a banana and peanut butter, fruit and yogurt or chocolate milk.
Amount post run: 0.55g per pound of bodyweight. A 180-pound man will want to replenish 99g of carbohydrates within four hours of a workout or long run. So he might eat one banana (30 grams), one glass of chocolate milk (30 grams) and 10 whole grain crackers (35 grams).
Muscles incur micro tears that can cause soreness and inhibit your ability to recover properly. Post high-intensity and long runs, you can aid your body in a quicker recovery, and combining your protein sources with carbohydrates can optimize that recovery. Muscle-protein synthesis is highest one to two hours after exercise, making this the best time for consumption. Good post-workout protein sources include nuts, seeds, yogurt and eggs.
Amount post run: 0.55g to 0.64g per pound of bodyweight with a 4:1 ratio of carbohydrates to protein. A 130-pound woman should replenish 71 to 83g of protein after a workout or long run. She might eat yogurt with nuts and berries or a protein smoothie.
In general, your body’s preferred source of fuel at longer, higher intensities is carbohydrate. Fat can produce a lot of energy, but takes longer. Fat adaptation has been shown to help provide more sustained energy and allows for longer lasting glycogen stores, but carbohydrate will always be needed to prevent that dreaded bonk.
Daily consumption: The American Dietetic Association recommends 25 to 35 percent of total daily calories come from fat.
As your training increases, vitamins and minerals need to be increased to help the body repair and recover. In particular, vitamins B and C are not stored in the body and need to be replaced every day.
Minerals such as calcium, magnesium, sodium, potassium and chloride, which are lost in sweat, are needed to help prevent muscle cramping and cellular and brain function. These vitamins and minerals can be replaced through fruits, vegetables and lean meats. If needs are not being met, supplementation is a good alternative.
