To Eat or Not to Eat: The Pre-Game Soccer Question
The latest Sports Nutrition News from Nancy Clark: What to eat before playing soccer. Food is fuel.
That’s the question soccer players of all ages and abilities most commonly ask when I’m presenting a sports nutrition workshop. While most athletes expect a simple response, such as “Eat a banana” or “Have a slice of toast,” the answer is actually complex and depends on many factors. After all, we are each an experiment of one.
The following information can help you figure out the best way to fuel your body before you step out on the field.
Does what you eat within 30 minutes of soccer training offer performance benefits?
Your body can actually digest and use the food you eat before you play soccer as long as you are exercising at a pace you can maintain for more than 30 minutes. Research also suggests that eating a snack just five minutes before moderate exercise can improve performance compared to exercising on empty. Yet, if you will be doing intense exercise—a highly competitive game, sprint repeats, or heavy weight lifting session, you should experiment to determine the best time to eat.
You will likely feel more comfortable allowing two or three hours for your pre-soccer food to digest and empty from the stomach.
Will pre-soccer food cause heartburn or nausea?
While many soccer players can comfortably tolerate pre-soccer food, others experience stomach distress. If the food you eat within the hour “talks back to you,” figure out:
• Does the discomfort happen if you allow two or more hours for the pre-soccer food to be digested?
• Does the type of food cause the problem? That is, do a few pretzels settle well but a cup of yogurt feels acidic?
• Did you eat too much? Would half a bagel with a skimming of peanut butter digest better than eating the whole bagel?
• Are you doing very high intensity work? If so, your stomach will shut down and your body will want to get rid of the contents…
What if I train in the early morning, before my stomach is awake?
If you drag yourself out of bed to exercise at early o’thirty, before your body and your mind are fully awake, you might not want to eat much of anything. I know of many athletes who eat their breakfast the night before. That is, instead of eating a bowl of cereal at 5:30a.m., they enjoy it at 10:00pm, before going to bed. This food helps them wake up in the morning with a normal blood glucose (blood sugar) level, and provides energy for an enjoyable and effective workout.
What if pre-soccer food contributes to diarrhea and undesired pit stops?
Food generally takes one or two days to travel through the intestinal tract. Hence, an undesired pit-stop during a Sunday soccer game might relate to food that you ate the day or two before.
That is, if you ate an unusually large bowl of high-fiber bran cereal on Saturday when carbo-loading for the Sunday game, you might end up wishing you’d carbo-loaded on low-fiber corn flakes or Rice Chex. Or maybe that bean burrito on Friday night caused the problem? You can try tracking your food and fiber intake, looking for suspicious patterns.
In general, exercise speeds up intestinal motility. With time, most bodies can adjust if you train your intestines to handle pre-exercise food. For example, one athlete started by nibbling on one pre-exercise pretzel, and then two, and gradually built up his tolerance to the suggested 100 to 300 calories of carbs consumed within the hour pre-exercise. He enjoyed the benefits of feeling stronger at the end of his training sessions.
Should I purposefully not eat before I exercise because I want to lose weight while I exercise?
One client reported she didn’t eat before soccer practices because she was exercising to burn calories. Why would she want to add calories to her diet? Wouldn’t that defeat the main purpose of her workouts?
Think again: If you consume 100 to 300 calories before you train, you will be able to run harder, longer, or at a higher intensity and burn more calories than if you schlep through the session on fumes, with little enthusiasm or enjoyment. (Plus, you will not be as hungry afterward and will be able to refrain from over-indulging.) Trust me, the plan to exercise-on-empty is hard to sustain; it is not fun.
Food is fuel. As a soccer athlete, you need to fuel your body appropriately—including pre-exercise. Just as you put gas in your car before you take it for a drive, you want to put fuel in your body before you embark on a busy day. Be as nice to your body as you are to your car.
By eating nothing before my morning training, won’t I burn more fat?
You may have heard you can burn more fat during low-level “fat burning exercise” if you do not eat beforehand. Yes, you might burn more fat than carbohydrates, but burning fat differs from losing body fat. You lose body fat when, at the end of your day, you have created a calorie deficit. That is, you will lose body fat (weight) if you have eaten only 1,800 calories by bedtime, even though you burned off 2,200 calories during the day. By fueling pre-exercise, you can have a better workout—and perhaps burn more calories than if you were to run on fumes.
To lose body fat, I suggest you fuel adequately by day, so you will have the energy to enjoy an active lifestyle, and then lose weight at night by eating a lighter dinner. Fueling by day and dieting by night (so you lose weight when you are sleeping), is far preferable to restricting by day only to over-indulge at night due to extreme hunger.
Can training on empty enhance endurance?
Some recent research suggests that highly competitive athletes might be able to enhance their performance if they train under-fueled a few times a week. These depletion workouts can alter muscle metabolism so that the muscles are able to compete better when fully fueled.
If you want to “train low,” be sure to do your important high-intensity workouts when you are well fueled. You cannot (enjoyably) exercise hard when you are running on fumes. Your performance will suffer unless you do some high quality hard runs when you are well fueled.
THE BOTTOM LINE
Performance starts with good nutrition. If you make the effort to travel to soccer games and tournaments, you might as well make the effort to eat well. No amount of training will outperform a bad sports diet.
