For Winning Strategy, Train How to Eat

January 26, 2011 @ 3:26 pm posted by

                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.

Sugar Hiding Everywhere

fresh veggies:  one of the few foods safe from sugar

Fresh veggies: one of few foods safe from sugar

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.

Sports Drinks

- 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.

The Connection between Glycogen, Carbs, Energy & Endurance

October 13, 2010 @ 4:23 pm posted by

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!

Extra Protein Benefits Most; Liquid Collagen my Choice

July 19, 2010 @ 10:26 am posted by

In my last column, I explained that whey protein is often a problem for lactose-intolerant people who are using a protein supplement. It’s easy to assume that a protein supplement is beneficial for only extreme athletes such as bodybuilders, but that couldn’t be farther from the truth.

Protein has many uses and supplementation is beneficial for a wide variety of users. They include the elderly; those with joint or degenerative diseases, or orthopedic conditions; the overweight; people who do heavy manual labor in their work, sport or hobby; those going through growth phases; people in physical rehab; men and women doing intensive training for a sport or competition; adults who work out on a regular basis; teen athletes who are trying to build muscle and strength; people taking symptomatic treatment for pain relief or inflammation; and anyone with pain resulting from excessive joint stress. Hardly anyone you know doesn’t fit onto that list somewhere.

The trick is getting that extra protein without absorbing a lot of extra calories, fillers or dairy products (as in the case of whey protein powder).

Collagen is a great way to get added protein. Did you know that collagen is the second-largest component of the human body after water? It’s a protein, and one found in muscles, joints, ligaments, tendons, bones and more.

Historically, physicians have used collagen to treat skin trauma, such as burns and wounds. But collagen also affects the hair, nails and overall healthy appearance of skin, which is why you see it advertised in high-end skin care products.

As we age, our bodies stop producing collagen protein, and sadly, it’s collagen that gives our skin elasticity. So the appearance of dry, wrinkled skin is really the lack of collagen. Supplementing your diet with a natural source of collagen protein doesn’t just make you more youthful looking, however. Collagen builds lean healthy muscle – the muscle of youth – as well as healthy joints and bones. Can you think of a better supplement to give the special elders in your life?

Collagen protein also helps aid in the repair of muscle tissue. Because a good workout or physical exercise is actually breaking down the body’s muscles, collagen protein assists in the rebuilding process. Collagen makes it possible to heal faster, simultaneously building leaner muscle, following a workout. Some will even find they sleep more soundly when taking collagen protein. Sounds better all the time, doesn’t it?

You may wonder why a person can’t just eat more protein and gain the same benefits. It’s about bioavailability. Protein in food form has calories, of course, and a healthy daily diet only contains so many. The bioavailability of the protein also comes into question. By the time your body works to chew and digest the food, you’re not getting nearly as much protein as the amount you started with on your plate.

A powder form can provide extra protein without as much work for the body, but comes with the added calories of what it’s poured into. A liquid protein is your best bet. Find one that’s small in calories, and better yet, hydrolyzed – or “predigested” – which simply means that you ingest it in its smallest form, with no extra work for the body to break it down.

I encourage you to join me – and my husband and my teenage son – and add a low-cal collagen protein supplement to your diet. You could be amazed at the changes you experience. See the developing abs on the teen in the photo? That’s my son Cody, who drinks a liquid collagen protein supplement and works out regularly.

Staying Hydrated is Essential to Health

September 15, 2009 @ 12:57 pm posted by

You can improve performance by delaying dehydration

Hydration is often left out of nutrition, but it shouldn’t be. Staying hydrated is important not only to improving performance in sports and other activities, but it plays a vital role in helping maintain a balanced diet and healthy lifestyle.

Necessary to the healthy function of all internal organs, water must be consumed to replace the amount lost each day during basic activities. Water is also proven to aid in weight loss. It helps you feel full so you eat less, quenches thirst without adding calories and allows your body to function at its top capability.

Keeping hydrated helps muscles look more toned, a look that many people desire. Being hydrated also helps your skin look and stay healthy.

Water regulates the body’s temperature, cushions and protects vital organs, and aids the digestive system.

In 2004, the Food and Nutrition Board released new dietary reference intakes for water. It is recommended that women consume 2.7 liters daily and men consume 3.7 liters through various beverages, 80 percent, or in food, 20 percent.

Active individuals need even more, particularly if they’re exercising in hot weather. This is especially important during the 24 hours prior to vigorous exercise. During exercise, our body produces more heat, causing sweat to cool us down. When we sweat out our water supply, we must consume more water to keep our core temperature down.

In one hour of exercise, the body can lose more than a quart of water, depending on exercise intensity and air temperature. If there is not enough water for the body to cool itself through perspiration, the body enters a state of dehydration.

For people who regularly exercise, maintaining a constant supply of water in the body is essential to performance.
Dehydration leads to muscle fatigue and loss of coordination. Even small amounts of water loss may hinder athletic performance.

In a dehydrated state, the body is unable to cool itself efficiently, leading to heat exhaustion and possibly heat stroke. Without an adequate supply of water, the body lacks energy and muscles may develop cramps. To prevent dehydration, you must drink before, during and after a workout.

During exercise, water is the best fluid replenisher for most individuals, although sports drinks help replace lost electrolytes during high intensity exercise exceeding more than 60 minutes. Keeping hydrated can improve performance by delaying dehydration and maintaining balanced blood-sugar levels during exercise. It also lowers the risk of catching a cold by boosting your immune system.

Drink 17-20 ounces of water two to three hours before the start of exercise. Drink 8 ounces of fluid every 20 to 30 minutes prior to exercise or during warm-up. Drink 7 to 10 ounces of fluid every 10 to 20 minutes during exercise. Drink an additional 8 ounces of fluid within 30 minutes after exercising. Drink 16-24 ounces of fluid for every pound of body weight lost after exercise.

Water is your best option. Tea (non-caffeinated and unsweetened) and 100 percent juice, not cocktail drinks, are good alternatives if you just need something else. Sports drinks are also good for your body during and after exercise.

Coffee and alcohol don’t need to be nixed completely, but should be consumed in very small amounts. Two cups of coffee a day isn’t going to help your body and scientific evidence suggests alcohol consumption can interfere with muscle recovery after exercise and negatively affect a variety of performance variables.

As far as options that you should stay away from, soda is at the top of the list. While drinking one soda probably won’t hurt you, it provides little hydration. In fact, frequent consumption of soda can be more harmful to your body than any of the other drinks listed above, with the exception of alcohol.

In the end, staying hydrated by drinking water throughout the day and especially during exercise is highly recommended to support good nutrition and healthy living.

Nutrition tips for young athletes

September 3, 2009 @ 8:40 am posted by

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.
