Listed below are the sports nutrition topics we will be discussing in this section:
- Eating Before, During, and After a Run
- General Sports Nutrition Tips for Runners
Carbohydrates Why are carbohydrates so important?
Here’s the easy one-word answer: Energy!
Carbs (as they’re sometimes referred to), are your body’s main source of energy for aerobic exercise. Your body coverts the carbohydrates you eat into glucose (a simple sugar). Glucose is then immediately used by your body for energy or is stored in the muscles as glycogen. Glycogen stores are utilized by runners and help keep you from "bonking" or "hitting the wall". You’ve run out of carbohydrates if you have to slow dramatically to continue running.
So, how do you keep from "hitting the wall" or running out of glycogen stores?
The trick is to store energy by eating carbs on a continuous basis. Experienced runners focused on meeting their sports nutrition needs eat the right carbs in the right amounts at the right times! Experts recommend that your diet should consist of 60 to 65% carbohydrates. This amount will keep your muscles well-fueled so that you can meet both your sports nutrition and training goals.
Carbohydrates are broken down into two basic categories:
Simple carbohydrates are the most basic form of sugar. Examples of foods containing simple carbohydrates are candy, fruit and sodas. These foods can provide a quick burst of energy-but it’s only temporary. For this reason, you should keep simple carbohydrate snacks to a minimum. But feel free to enjoy a treat every now and then, especially after a good run.
Complex carbohydrates provide energy on a more consistent, long-term basis. That’s why experts recommend that the majority of the calories you get from carbohydrates be in the form of complex carbohydrates. Foods that are high in complex carbohydrates include cereals, pasta, breads, rice, potatoes, and vegetables. It’s important that you maintain a diet high in complex carbohydrates to support your running program and meet your sports nutrition needs.
Fats Fats, in many cases, get a bad rap. The confusion lies in how much fat is healthy in your diet as well as the type of fat you should be eating.
So what’s the bottom line?
Your body needs fat but not all fats are created equal!
Each type of fat is okay in limited amounts, but some fats better meet your sports nutrition needs than others. Fats are classified as:
Saturated fats are easy to spot. They remain solid at room temperature. Common examples include red meat and dairy products. These fats are required by the body in small amounts and should make up just 10% of your overall caloric intake.
These fats stay semi-solid at room temperature. Many margarine and butter alternatives as well as vegetable oils are made with poly-unsaturated fats. Poly-unsaturated fats are a step closer to the "good" fat you should make a staple of your diet. However, you can go one step farther.
Mono-unsaturated fats are liquid at room temperature. Examples include olive oil and most other natural oils. Recent studies have shown that diets with a higher proportion of mono-unsaturates seem to reduce the risk of heart disease and better meet your sports nutrition needs. As a result, you should obtain 20 to 25% of your daily calories from fats with the majority of those coming from mono-unsaturated fats.
Protein As you exercise and eat right, you’ll feel your body getting stronger.
Proteins absorbed during consumption.
Protein helps to build muscle and tendons, repair broken down muscles, and regulate hormones. Meats, eggs, beans and nuts are common examples of foods that contain significant amounts of protein. Experts agree that runners need 10 to 20% of their daily calories from protein.
Most people, however, eat two to three times their protein requirement each day!
As a runner, your increased caloric intake needed to maintain a sufficient energy level for running should be more than enough to meet your recommended protein and sports nutrition requirements.
Water Did you know that water makes up between 60-70% of your total body mass? Although water doesn’t provide energy (or calories), your body requires large amounts of H2O in order to function properly. It’s a sports nutrition requirement.
Water regulates the core temperature of your body. As you run, your working muscles produce large amounts of heat that must be released in order to prevent your core temperature from rising to dangerously high levels. To dissipate this heat, your body perspires causing water loss and potential dehydration.
As a runner, you should consistently hydrate yourself during both warm and cold weather. By the time you are thirsty, your body is already suffering from dehydration, causing your running to suffer, and putting you at risk. Most runners fall short on their fluid replacement and manage only to replace about half of their losses. You know you’re drinking enough water if you urinate about once an hour and it is clear. Finally, spread out fluid intake during the day to maintain steady water levels and remember to drink past the feeling of thirst to adequately replenish lost fluid.
Vitamins/Minerals/Supplements Concerned that your sports nutrition needs are not being met? Looking for the latest pill, shake, vitamin, mineral, or supplement to help you gain a leg up on the competition (or your running buddy next door)?
In most cases, all you have to do is follow the advice your Mom gave you: Eat a varied, well-balanced diet.
A varied, well-balanced diet will include plenty of fruits, vegetables, and non-processed foods. One way to ensure that you are getting all the fruit and vegetables you need is to eat them as healthy snacks throughout the day. While fruits are an obvious snack, crispy handfuls of carrots, celery, cucumbers or other favorite vegetables make great desk foods. Juices are also a great way to consume your daily allotment of fruits and vegetables. The advantages of juices include helping to keep you hydrated, contain a wide variety of vitamins and minerals, and they provide a source of energy all day long.
In recent years, several major studies have shown that it makes sense for runners to supplement their normal dietary intake with the antioxidants vitamins C and E and betacarotene. Vitamin C can be obtained easily through either fruit juices or supplements. Vitamin E, on the other hand, is not so easily obtained within the diet. Sports nutrition supplementation is an answer. Shoot for 30 to 200 international units per day.
If your diet is somewhat unbalanced and/or you feel you need some sports nutrition insurance, daily multi-vitamins with minerals are the answer. A daily multi-vitamin will help you meet your daily recommended allowances but, remember, they are not an excuse to not to eat right.
You still need a variety of whole foods – especially fruits and vegetables.
Eating and Hydrating Before, During, and After a Run Pre-run
Consume 25-50g of carbs 1-2 hours before exercise. Try an energy bar, toast, bowl of cereal, bagel, or a banana. Avoid foods that are likely to upset your stomach and bowel such as: greasy foods, high-fiber foods, high protein foods, and caffinated drinks. Drink 8-16 oz. of water or combine with the above in a carbohydrate drink.
Consume 25g of carbs for every 45 minutes of exercise. Go for a gel pack or sports bar and remember to wash them down with water. Gel packs typically contain 25-30 grams and are easy to digest. Drink 4-8 oz. water or diluted sports drink for every 15 minutes of exercise. The consumption of sports drinks and carbohydrates during most runs reduces the stress on your body and improves your post-run recovery.
Consume 25-50g carbs immediately after exercising. This can be a combination of food and drink. You will need to re-hydrate with water while eating an energy bar, bagel, or some form of carbohydrate. An alternative to combining food and drink is to drink 25-50 grams of carbohydrates in a sports drink if you have a hard time eating right after a workout.
Drink 16 oz. of water for every pound lost during exercise and continue to drink water throughout the day. Consume another 25-50g carbs 30 minutes after exercise. One hour after running consume 50-100g of carbs and 20-40g of protein. This is a great time to eat a well balanced, sit-down meal. Soup and a sandwich, salads, whatever suits your tastes. Chicken and tuna are great sources of protein. Consume 50-100g of carbs per hour and 20-40g of protein every 2 hours. Continue to do this for 6 hours after your run. You will find that by following this sports nutrition routine, especially on your long run days, you’ll feel refreshed rather than exhausted after your workout.
