Macronutrients, the role of Carbohydrates, Protein and Fat

CARBOHYDRATES
Carbohydrate is the main source of energy for athletes. Plan to include carbohydrates in all your meals and snacks. Optimal carbohydrate sources include whole grain cereals, breads, pasta, rice, potatoes, fruits and vegetables and low fat milk/yogurt.

Carbohydrates
•Maintain blood sugar levels
•Spare protein utilization as energy
•Supply liver and muscle glycogen stores
•Optimize recovery
•Help prevent mental fatigue

Grains
•Make half your grains WHOLE grains!
•Rich sources of carbohydrates, fiber, several B vitamins (thiamin, riboflavin, niacin, & folate), & minerals (iron, magnesium, & selenium)

Aim for 5-10 ounces daily
•What counts as 1 ounce?
–1 slice bread
–½ cup rice, pasta, cooked cereal, or starchy vegetables
–1 cup ready to eat cereal

Vegetables
•Vary your Veggies!
•Eat more dark green and orange veggies, THINK COLOR
•Packed full of nutritional benefits

Aim for 2-4 cups daily
•What counts as a cup?
–1 cup chopped, sliced, raw, cooked, or canned vegetables
–2 cups raw leafy vegetables (ie: Spinach, romaine, watercress, dark green leafy lettuce, endive, escarole) is equivalent to 1 cup of vegetables
–12 baby carrots, 2 large celery stalks, 3-5” long broccoli spears

Fruits
•Focus on a variety of whole fruits, go easy on fruit juices!
•Packed full of micronutrients

Aim for 1 ½ -2 ½ cups daily
What counts as a cup?
–1 cup fruit, 100% fruit juice or ½ cup dried fruit
–1 small apple, 1 medium pear or grapefruit, 1 large banana, peach or orange

Dairy
•Many cheeses, whole milk, & products made from them are high in saturated fat & cholesterol, whenever possible choose low-fat or fat-free milk or soy products.

Aim for at least 2-3 cups daily
What counts as a cup?
–1 cup of milk or yogurt
–1 ½ ounces of natural cheese
–2 ounces of processed cheese

PROTEIN
The role of protein is for muscle growth and repair, and to support a healthy immune system, not to be a fuel for exercise. Ounce for ounce, all types of meat and fish – red meats, pork, poultry, etc. have about the same amount of protein. Plant foods such as dried beans, soy products, nuts, seeds and legumes are excellent sources of protein as well as dairy foods like milk, yogurt and cheese. Grains and vegetables contain small amounts of protein too.

Protein
•Build strong muscles and tissues
•Repair damaged muscles and tissues
•Carry oxygen around the body
•Component of antibodies, enzymes and hormones
•Females: tend not to get enough
•Males: tend to eat high fat protein foods
TIP: You need about 0.5 to 1 grams of protein per pound

Protein Sources
•3 oz chicken, beef, fish or pork (~24g protein)
•4 oz tofu (~28g protein)
•1 cup milk (~8g protein)
•1 cup yogurt (~6g protein, new Greek yogurts have more)
•½ cup cottage cheese (~14g protein)
•1 egg (~7g protein)
•2 Tbsp. peanut butter (~8g protein)
•Grains provide a small amount of protein (~2-3g per serving)
•Fruits and vegetables varying amts (~0-2g per serving)

FAT
Athletes should not follow a fat-free diet. According to current guidelines, individuals should get 20% to 35% of total energy intake from fat. Athletes who drastically restrict fat intake may become deficient in essential fatty acids and fat-soluble vitamins. In females, very-low-fat intake has been associated with menstrual irregularities and higher injury rates.

Fat (lipids)
•Energy source during low to moderate intensity exercise
•Supports and cushions organs
•Component of hormones
•Supply of fat-soluble vitamins
•Concentrate on unsaturated (healthy) fats

Fats & Oils
“Good fats” (unsaturated fats)
Nuts, fish, & vegetable oils.
Liquid at room temperature.

“Not-so-Good fats” (saturated fats)
Butter, lard, shortening, stick margarines, & fatty meats.
Solid at room temperature.

Aim for 5-10 teaspoons of fats daily
•1 tsp = 5 g fat
•1 tsp oil, margarine, or mayonnaise
•2 tsp peanut butter,
•1 tbls salad dressing, or 2 tbls light salad dressing
•1/8 avocado, 1/3 oz nuts (10 almonds, 2 lg pecans, 6 small walnuts)

TRI-al by Coach: Spinervals

Since it’s been too cold to bike until recently, I spent the winter inside taking spinning classes and using an indoor spin bike I have at home.  I was curious to compare the workout I get in a spinning class versus a home workout.  Plus, I had always wanted to try out a Spinerval DVD.  Here are the results of my very unscientific survey.

Spinning Classes:
Pro:  Under the guidance of a talented instructor, a spinning class can be a great workout and a great time.  Between the music and the spin buddies, I have no issues with spinning classes.

Con:  Those poor spin bikes!  No matter how much my club maintains the bikes (maintenance which might be open to debate), the spin bikes take a major beating.  Between the constant adjustments and all the sweat, most of the bikes are showing signs of age.  Toss in having to get there early to grab a bike, and a spin class could be a major bummer if your bike is a lemon.

Spinervals:
Pro: There is nothing like picking your own time for your workout.  The coach on the Spinverals DVD is very motivating, tells you exactly what cadence/RPM you should shoot for and there are no annoying or sweaty people riding next to you.  The workouts are very efficient and if you don’t cheat, highly effective!  You don’t need a spin bike, you can purchase a bike trainer and use your own road bike.  Most of the people in the DVD are using road bikes on trainers.

Con: I won’t lie to you, it can be tough to motivate yourself.  You’re biking all alone in your home and if you don’t push yourself or heck, if you even quit early, no one will know.  But you will know!  And that’s what keeps me going.

Yesterday (April 9), I went for my first ride outside!  I road 25 miles on flats and hills and I could tell that my winter indoor riding had made a difference.  So, whatever you decide; spin class at the gym or Spinevals at home…do something and come racing season, you’ll be happy that you did!

If you’d like to try a Spinerval DVD, click the photo below to purchase one.  This one has three 30-minute workouts; beginner, intermediate and advanced.  If you like this one, there are more Spinervals to purchase based on what you want to get out of your workouts.
