You don’t have to be a hard-core athlete to appreciate endurance. Sometimes we want to push ourselves physically, for all sorts of reasons. Walking 18 holes. Winning the football game. Playing doubles. Running that annual 5K. A long bike ride on Saturday.
So it’s “competition” day . . . now what? You may have trained and trained, but have you consistently fueled your body with the right substances (foods and fluids)? It really matters what fuel you choose; why wouldn’t it? And the body’s energy is finite: if it’s not resupplied, it will run out. Push it hard, it runs out faster. Fuel incorrectly, and all your training will be for naught. What a pity.
Here are some Keys to give you a competitive edge. They will unlock a new level of physical success for you, in whatever arena you need it.
Key #1. Plan, plan, plan. You already know you need to prepare physically for an event. But even more key is planning ahead nutritionally. Take time to learn how starches, carbs, protein and hydration fuel the body for highly physical endeavors, and how they’re also used to help it recover quickly, building lean muscle tissue as a result. I’ve given you some great starter tips below.
Key #2. Practice, practice, practice . . . but I don’t mean training! Literally practice your “competition day” eating before that important event. A coach once told me ‘ if you put the maximum effort into your practice, you will have the maximum benefit during your game days.’ Now I tell all my athletes that same thing.
Key #3. Fuel properly the night before. The big pre-competition “no-no’s” are 1) anything with a lot of sugar; 2) fried or spicy foods; 3) high fat foods: gravies, sauces, creamy soups, fatty meats. And DON’T try any foods you’ve never eaten before.
Key #4. Same no-no’s apply on game day. Eat starches approximately 3-4 hours prior to your event, and make the portions slightly smaller than normal meal. They give you “timed-release” energy. About 30-60 minutes before starting the event, top off your tank with fluids and a small snack (a piece of fruit or granola bar).
Key #5. During your competition (or on tournament days with multiple events or games) make sure you’re drinking at least 8-12 ounces of fluids between each game or event. Eat a healthy snack – such as yogurt, a sports bar or trail mix – between each game and event. If you’re exercising for longer than an hour without taking a long break, you need to keep refueling during the event, with foods like pretzels, fruit, granola or fruit snacks. Remember: drink plenty of fluids!
Key #6. When in doubt DON’T go without! Some people find that liquids are easier on their stomachs while they exercise. But what’s in the liquid is critical. Don’t go without proteins or nutrients; try chocolate milk, smoothies, or meal replacement shakes.
Got it? Plan ahead, practice, hydrate and don’t go without fuel.
Whether you’re trying to lose weight, lower your sugar intake for overall well-being, or wean your kids off sugar, you need to recognize sugar in its many forms. It’s amazing how many different words mean “sugar” on the contents label of a food or drink.
It’s also unbelievable how many food products include sugar in one form or another. To boost to your wellness plan, you have to know sugar terminology, and you have to know how to interpret the label (and teach your kids). The top three ingredients listed on the label are primary, so if you see a sugary term there, the product is loaded.
Some ingredients to watch out for: corn sweeteners, evaporated can juice, cane sugar, high fructose corn syrup, confectioner’s sugar, dextrin, honey, invert sugar, maple sugar, raw sugar, malt molasses, turbinado sugar, brown and white sugars.
I was also taught, while earning my dietitian degree, that “if it ends in OSE, it means sugar.”
Sucrose, lactose, dextrose and maltose … Watch out!
Sugar has invaded many products where you don’t expect to find it. I’m talking about things such as salad dressings, canned foods, pasta sauces, lunchmeats, “healthy” cereals and granola bars, dried fruit snacks, and more.
It’s no wonder the average American consumes 128 pounds of sugar per year. Prepared foods are hiding pounds of sugar, and adding pounds of fat, especially to our kids, who are at grave risk for diabetes. (Ouch, that hurts me to just write that).
Hopefully you’re aware how much sugar is packed into a regular soda, but sports and energy drinks are culprits that often fly under the radar. Because their purpose is “beneficial,” these drinks make it easy to forget that their labels are also important. But that 20-ounce Powerade you rely on to hydrate you has more than 8 teaspoons of sugar in it!
Some other big offenders (teaspoons of sugar per drink in ounces)
- Propel: 1.5 tsp per 16 ounces
- Vitamin Water: 7 tsp per 20 ounces (this one surprised me).
- Regular Powerade: 8.3 tsp per 20 ounces *
* Powerade and Gatorade do have low sugar options.
- Full Throttle: 13.8 tsp per 16 ounces
- Jolt Energy: 22.3 tsp per 23.5 ounces
- Amp: 7.3 tsp per 8.4 ounces
- Monster: 12.8 tsp per 16 ounces
Other drinks that pack in the sugar
- 7-up: 9 tsp sugar per 12 ounces
- A & W Cream Soda: 11 tsp sugar per 12 ounces
- Average cola: 10 tsp per 12 ounces
- Nestlé’s Ice Tea: 8-14 tsp sugar per 16-20 ounces
The bottom line: high sugar intakes are contributing to an epidemic of obesity in this country.
Exercise requires energy, pure and simple. But where does it come from? The answer is glycogen. But what is it?
When we digest food we’ve eaten, the carbohydrates are broken down by our bodies into glucose, and then the glucose is stored in our muscles . . . as glycogen. During periods of exercise, this process reverses, and glycogen converts to glucose once again, so that is may be used for energy. How long we “last” is greatly influenced by how much glycogen we have stored in our muscles.
Exercise that lasts less than 90 minutes is typical for most of us. Carbs typically provide 40-50% of our energy in the beginning stages of moderate exercise. What the body naturally stores will sustain you through a workout of this length.
But as the intensity of physical activity increases, the body’s carbohydrate consumption increases too. For events over 90 minutes, eat a heavy-carb diet for 2-3 days prior.
Picture the muscles like porous rocks. The more glycogen is filling all those crevices, the more energy reserves we have to draw upon. This is why cyclists, marathoners, triathletes, soccer players and other endurance athletes excel when they’ve pre-loaded for 2-3 days with about 70% carbs. Glycogen is the fuel which sustains the body in highly physical situations.
Have you heard the term “hitting the wall?” This refers to an actual event in the body, the depletion of glycogen. Once stores are gone, energy is truly kaput; you have no way to generate more.
Don’t assume you should eat a high-carb diet all the time, though, even if you exercise heavily. Once glycogen fills all the areas where reserves can be stored, any extra that is produced is stored as body fat. Eating too many carbs causes this excessive glycogen production.
Another danger of overdoing carb consumption: you can unwittingly “train” your body not to utilize essential fatty acids that come from fat. Not only does fat transport cholesterol and play a role in blood clotting, it helps us absorb vitamins and produce hormones.
Conversely, eating too few carbs forces the body to use protein for energy. The body will actually start to break down protein – the building blocks for muscles, bone, and other tissues – meaning you put yourself into a sort of self-cannibalization. Your body starts to feed on its own muscles and you lose muscle mass. This is also tough on kidneys. Not a pretty thought.
So strike a happy balance between protein, carbs and fat, and remember lean protein, high fiber and unsaturated fats as your first choice. It’s all about balance and timing: my 80/20 rule. Athletic training is 80% nutrition, 20% training. Get the food right, you have a bonafide mega-advantage over the competition.
Michelle Ciuffetelli, a Certified Personal Trainer in Fort Myers, Florida, says her favorite carbs are oatmeal (filling and a good source of fiber); sweet potatoes; fruit (a great snack); Arnold Sandwich Thins (good fiber); and Flat Out wraps (taste great, can wrap anything).
Now get moving. That’s a wrap!
What cyclists eat and drink determines how fast and how far they can ride. What are your goals? Recreation, competitive racing, or heavy-duty triathlons? Even recreational riders should pay attention to their diet; maximize your ride and get the body you want. All athletes and exercisers need energy to function.
Many cyclists avoid caffeine, knowing it’s a diuretic, but here’s a surprise. During endurance exercise, the dehydrating qualities of caffeine are practically nil with small amounts of caffeine. And studies have shown that it may help the body burn fat, rather than carbohydrate reserves.
Coffee is not an ideal source of caffeine for exercisers or athletes – therefore, don’t think you can justify your Starbucks habit. We have only 1,500-3,000 calories of reserve carbs, but the body stores 70,000 fat calories at any given time, so burn, baby, burn.
Each hour of an intense bike ride will use 500-1,000 calories. Your overall protein needs will increase during exercise; supplement at 1.2-2. g protein per kilogram of body weight per day depending on your intensity and length of exercise.
For endurance events, you can increase your carbs three days prior. This maximizes the body’s glycogen stores. While you ride, you need 30-60 g of carbs for each hour beyond the first hour. An energy bar works.
Practice eating while you ride and don’t change your food choice on race day. Remember, fat can contribute as much as 75 percent of your energy demands during endurance training. Keep foods simple.
During a ride in hot weather, the body’s ability to digest becomes compromised. Liquid foods avoid this situation, and keep you speeding along without much hassle. Certain energy drinks can fill the bill, as does an Ensure protein drink, available in any drug store.
Ensure also comes in powder form; having baggies of it allows you to add it to water, drink a meal, and continue on. You can also mix fruit juice and water for a source of hydration, carbs and sugar for your blood.
How’d you like to burn 350-500 calories per hour, doing something that’s refreshing and widely available? If your answer’s yes, then go put on your swimsuit and keep reading. Swimming is great exercise, whether you do it casually or in a serious, “endurance sport” manner.
Triathletes must make diet their primary focus if they want to significantly improve their performance. But for any type of athletic conditioning, nutrition is at least 80 percent of the formula, and training makes up no more than 20 percent.
Keys to the 80/20 formula are quality, quantity, and timing of nutrients … learning not only what to eat but also “how and when” will maximize results in triathlons, multiple-sport activities, and even for recreational exercisers. Developing good eating habits every day can make the difference between great training/exercise/events, and just struggling through.
Note that I said “habits.” Eating well can become a habit over time, one you no longer have to think about, or feel burdened by in any way. Commit to the concept of positive, life-enhancing, sport-enhancing long-term change through diet, and over time, you will develop this good habit just as easily as people develop bad ones.
Now, back to the pool. Is there any truth to the phrase “no swimming until one hour after you’ve eaten?” Yes, a bit, but only if you’re planning on swimming with extreme intensity, as in a triathlon.
Recreational swimming falls in a different category. You, your children or grandchildren can all swim or play in the pool after eating. Frolicking with a full belly is perfectly safe.
In fact, if you plan to swim in the morning – especially just after rising from a night’s sleep – eat something. Engaging in vigorous exercise on an empty stomach will cause you to suffer. You’ll feel weak, possibly dizzy, perhaps sick to your stomach. Certainly your workout will be a poor one and most likely will have to be cut short.
After sleep, your blood sugar is low. So have a snack before you hit the pool.
Swimming is less demanding than running or cycling for pre-activity nutrition. Even fruit, toast or a sports drink will do, to elevate the blood sugar a bit. Hydration before or during swimming is not much of an issue because you won’t overheat in water, but hydration after swimming restores electrolyte balance.
In all three triathlon sports, post-workout nutrition should occur within 30 minutes of stopping, when the body is most receptive to carbs for replacing glycogen lost during the workout. Ingesting protein will help muscles recover and rebuild stronger.
Women swimmers especially need to be aware of the potential for iron and/or calcium deficiencies. Lacking either or both of these essential minerals will affect performance.
Remember the 80/20 rule and decide now to develop good habits. It does not matter how hard or how much you exercise; good nutrition and healthy eating habits are the crucial component. Next week we’ll discuss nutrition for cycling.
Whether you’re a triathlete, a recreational or endurance runner, or even a power walker, your body relies on proper fuel to do what you ask it to do. Training will take you only so far, no matter how religiously you do it. Here’s a surprising statistic I mentioned last week: nutrition counts for 80 percent of athletic training.
I’ve always been an advocate of eating whole-grain foods – breads and pastas, wild rice, veggies, beans and oatmeal – but you must read labels carefully. Whole wheat does not equal whole grain.
Runners also need “good” fats, typically 20-30 percent of daily intake. Fat is energy for muscles, once quick-burning carbs have been used. Avoid trans fats. Heart-healthy omega-3s come in walnuts, flax seeds, cold-water fatty fish, soybean and canola oils and even tofu.
Don’t forget protein. A total of 15-35 percent of a runner’s diet should be lean proteins such as fish, poultry, low-fat dairy, nuts and seeds. Avoid foods high in saturated fats and cholesterol.
Find the percentages that work for you, and remember: hydration is key to the formula, and timing is everything. Drink early: do NOT wait for thirst to set in. Think of hydration as a pro-active commitment, not as a fix for thirst. Watch your urine: if it’s pale, you’re drinking enough water.
Always choose a pre-exercise meal that’s low in fat and fiber, is high carbohydrate and includes moderate protein. That’s the formula for endurance and energy.
While running, consume approximately 8 ounces of water every 15 minutes. If you’re exercising longer than an hour, alternate water and Gatorade about every 15-20 minutes. For high intensity workouts, I also suggest a sports drink like G2 (Gatorade2).
After running, you need 3 cups of fluid for every pound lost. Your body also needs protein and carbs (like chocolate milk and trail mix). A protein boost within 15-20 minutes of ending your workout will dramatically affect how your muscles rebuild and replenish.
The time period right after exercise – your short-term “recovery” window – is the most critical for improving your body. Training breaks down muscles, literally, and depletes natural energy stores (glycogen). During recovery, muscle tissue begins to repair and in so doing, strengthens. Energy replenishes.
Timing is key. Your short-term recovery window is only about 45 minutes, and can be wasted during a post-workout chat and/or drive home. Once this window closes, your muscles will no longer be receptive to the nutritional assistance you could have provided.
Bottom line: have a snack immediately following a workout that contains carbohydrate and protein, for this critical period. You’ll start to see a real change in your muscle tone, endurance and energy.
A good post-exercise meal, within 60-90 minutes, could be salmon, brown rice, broccoli, peppers and carrots. Let your body enjoy long-term recovery on “no-workout” days, while you focus on a healthy diet. And don’t skip meals. I personally eat six small meals a day.
Next week: nutrition for swimmers.
Over the next four weeks, I’m going to talk about proper nutrition for a variety of sports: running, swimming and cycling. Many Floridians participate in one or more of these physically demanding (but fun) outdoor activities. A few combine them for triathlons – my cap’s off to you.
And here’s the thing. The human body can excel at a demanding sport only when fueled correctly. This may shock you, but proper nutrition is at least 80 percent of the formula for successful exercise and athletic training.
Don’t be misled by my use of the word “training.” If you’re a soccer mom taking a lot of classes to keep your tush looking toned, you are training. Dads who cycle five nights a week to keep the effects of aging at bay are training. And, of course, if you’re an individual or team athlete striving for wins, records, medals or the like, you know I’m speaking to you.
But you can train seven days a week – devoting hours and hours of your life to your pursuit – and without giving your body what it needs to support and achieve those goals, you will not end up where you want to be, including in the weight department. You may not even come close.
Picture Kyle Busch on the track in Indianapolis, and his car without the right kind of gas and fluids. Nothing in his driving skills can overcome the fact that his vehicle is not fueled for the task, and your body is no different.
Sports nutrition has many components. Sure, it’s important what foods you include in your daily diet, be they carbs, protein, fats, sugar or liquids. Carbs and proteins both have specific functions. We must understand what our body needs, how it uses what we give it and how we can maximize what it naturally provides. This is how we learn to boost our energy reserves so we can train harder, build lean muscle and avoid storing fat.
As important as what an active adult eats is the timing of when it’s eaten. I’ll talk about how and why to “pre-load” for a workout, and how nutrition can speed up post-activity recovery. Much of our body’s healing from exercise takes place while we sleep, so nutrition for proper sleep is also critical.
Next week, we’ll start with nutrition for running. (If you spend time on the treadmill in your gym, this will apply to you.) All my running readers will gain a real footing on the road to success. It starts with nutrition.
Whether you are establishing a new exercise routine, increasing your fitness or looking for ways to maximize your existing plan, your body requires proper nutrition and hydration before, during and after you exercise.
Nutritional guidelines specific to sports, cardiovascular and wellness nutrition are designed to help you understand how much, how often and what kind of nutrients your body needs to improve performance and recovery.
For example, before exercise, it is important to consume a carbohydrate-rich snack or meal, along with small amounts of protein to help build and repair muscle tissue and reduce post-exercise muscle soreness. Low-fat and low-fiber foods are best to ensure optimal digestion.
Three to four hours before exercise, you should eat and drink a small meal or snack. Ideas may include:
- Peanut butter and honey on toast with an instant breakfast drink;
- Fruit and yogurt cereal with low-fat granola;
- Oatmeal with brown sugar and almonds, skim milk and a banana; or
- Turkey and cheese sandwich with fruit and a sports drink.
In addition, approximately 30 to 60 minutes before exercise, you should eat a light snack such as a piece of fruit or a small jam sandwich. Also, drink plenty of water or a sports drink.
Nutrition and hydration during exercise also is important, particularly during prolonged exercise such as a marathon or long bike ride. This requires the proper mix and timing of fluids, carbohydrates and electrolytes. Too much can result in cramping or other intestinal problems. Too little hydration can cause dehydration, fatigue and impaired performance.
Easily digestible foods such as a banana, low-fat granola or nutrition bars are recommended during endurance training and events. In addition, you should always drink plenty of water or sports drinks that contain carbohydrates and electrolytes to help speed fuel to muscles.
For short duration exercise, less than 60 minutes, water is a good choice to drink before, during and after exercise.
Following exercise, eating for recovery is important to restore fluid and electrolytes lost in sweat, replace muscle fuel utilized during activity and to provide protein to aid in repair of damaged muscle tissue and to stimulate development of new tissue.
If you have two training sessions per day or your next training session is within eight hours, nutrition recovery is crucial. Ideas for recovery snacks and meals include the following:
- Fruit and yogurt smoothie;
- Sports drink and nutrition bar;
- Graham crackers with peanut butter, low-fat chocolate milk and banana;
- Whole wheat pita sandwich with turkey and veggies; or
- Rice bowl with beans, cheese, salsa, avocado and whole grain tortilla.
A nutritional plan tailored to help you achieve your personal exercise goals will help you maximize performance and results. Experiment with foods and hydration to create a custom plan that what works best for you. A registered dietitian can assist you in designing a program based on the amount and intensity of your exercise schedule and your desired results.
Whether you participate in sports activities, aerobics, weightlifting or a competitive fitness program, following proper nutritional guidelines is critical to helping you achieve your goals.
Back-to-school means back to the courts and fields for student athletes. Reaching peak athletic performance doesn’t mean you have bulk up on carbohydrates or chug the latest sports and energy drinks. Student athletes have unique nutritional needs, requiring approximately 2,000 to 5,000 calories per day, depending on body composition, amount of exercise and other health factors.
Here are some tips for fueling your body for optimal strength and energy:
-Eat a variety of foods including protein, carbohydrates, fats, calcium, minerals and vitamins; lean proteins, fruits and vegetables and dairy for calcium provide a balanced diet
-Avoid supplements and steroids, which can have negative side effects on your health
-Avoid extreme diets. Youth athletes require the proper amount of nutrition and depriving your body of proper nutrients can cause decreased energy, muscle loss and sometimes, more serious health problems
-Hydrate with water; avoid caffeine and sugary drinks
Before practices and games:
-Be sure to eat a small, balanced meal approximately 2 to 4 hours before the event and include proteins and carbohydrates such as a turkey sandwich, or pasta and tomato sauce
-No time for a meal? Eat a light snack less than 2 hours before the event such as low-fiber fruits, crackers or yogurt
-Hydrate by drinking plenty of water before, during and after sports activities; avoid caffeine
Because body sizes and activity levels vary from person-to-person, you need to alter your diet to fit your individual needs. For more information, visit http://www.mypyramid.gov/ and create a personalized plan that works best for you.
