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!
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.
