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.
If you’re going to mess around with whey, there are some things you need to consider. And recent news makes the topic even more important for those adding supplements to their shakes.
Remember Little Miss Muffet? Nobody ever told us, but she was lactose tolerant. How do we know? Because she was happily eating her “curds and whey.” Those of us not raised in Wisconsin are less likely to be familiar with these two words but they’re both dairy products.
Curds are made by curdling milk with an acidic substance like vinegar or lemon juice. The liquid portion which is drained off is whey. Whey is also a liquid by-product of cheese production. After childhood poems, the most popular exposure to whey is in “Whey protein,” commonly added to shakes by athletes, exercisers, body builders and people trying to gain muscle. It might surprise you to learn that whey is often hiding in our food products, even “non-dairy” items which are processed and prepared.
This is part of what makes trying a dairy-free lifestyle so difficult. To help sort through the nutrition labels, use this comprehensive list of the most common dairy ingredients present in foods. Whey is present in a variety of processed and prepared food products. Whey protein is composed of lactalbumin and lactalglobulin, and is found in both food products and health supplements. Other common forms of whey present in food products are sweet whey, whey powder, whey protein, whey protein concentrate, and whey protein hydrolysate.)
Here’s some great news for active adults. Even if they’re lactose intolerant, athletes, exercisers, body builders and people who want to gain lean muscle can still consume protein by using collagen instead of whey. It can be taken before and after activity: to pre-load before a workout, or to help with recovery after exercise.
Check the label and be sure the collagen protein you are choosing contains NO added whey. Some “newer” collagen proteins, such as AminoRip, contain NO lactose, NO dairy, NO carbs, NO fats, NO sugar, NO high fructose corn syrup (HFCS), NO sorbitol, NO gluten, NO soy, and NO whey.
Here’s another reason to pay attention to your choice of protein supplement. Consumer reports testing found that due to contamination, some “protein shakes” exceeded United States Pharmacopeia (USP) standards for exposure to heavy metals when three or more servings were consumed a day. Failing the heavy metal test were some of our most popular protein shakes, including EAS’s Myoplex and Cytosport’s Muscle Milk.
It’s easy to forget that whey protein is a dairy product, and important to remember that collagen is an alternative protein. If a person is, in fact, lactose intolerant, then ingesting whey protein can cause him or her to experience great discomfort with symptoms like abdominal discomfort, belly cramps, diarrhea, nausea, itch or watery eyes, and even possible asthma attacks. The more you consume, the more severe the symptoms would be.
Whey protein doesn’t cause the problem, but because you’re taking large amounts in a shake, symptoms can manifest themselves for the first time in people who generally are capable of handling small amounts of lactose. Lactose intolerance is different than a milk allergy, but people often confuse the two because the symptoms can be identical (bloating, stomach pain). These two conditions are not related, however. It’s the immune system which is reacting to a milk allergy.
Lactose intolerance, on the other hand, is all about the digestive system. Lactose intolerant folk don’t produce enough of the enzyme lactase, which is needed to break down the sugar in milk. Amazingly, it’s estimated that 75% of all people decrease in production of lactase during adulthood. The intolerance really ramps in during childhood, though, particularly for Mexican Americans who jump from 18% at age two to a whopping 47% by age 10. That’s a lot of potential tummy aches.
Non-dairy products may also contain lactose. If you know – or even suspect – that you’re lactose intolerant, then spend some time reading product labels. Any of the following ingredients mean the product has lactose: dry milk solids, nonfat dry milk powder, milk by-products, curds, and whey. It’s also good to know that dairy products which are “fat reduced” or fat free” generally present higher lactose, as do low fat foods, which often incorporate dairy solids.
I think I’ve milked this topic for all it’s worth and now I have a stomach ache. See you again next week.
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.
