Sports Drink vs. Chocolate Milk

Sports Drink vs. Chocolate Milk
2
What we already knew

• Endurance exercise depletes the body of energy
  stores (carbs).
• It is important to replace the lost carbohydrates
  within 30 minutes after intense workouts.
• Also, protein is important to assist with
  carbohydrate restoration and to help muscles
  recover and grow.

The Study

• Done at IU by Joel Stager and colleagues.
• Cyclists were given either a synthetic sports
  drink or chocolate milk immediately following
  their first session of exercise and again 2 hours
  later.
• Four hours later the athletes worked out again.

The Results Milk is superior!

• We found that chocolate milk was nearly twice as
  effective than the synthetic products as a
  recovery product and the athletes liked the
  taste a lot better, said Stager.

5
Why chocolate milk?

• "The latest research shows athletes ideally need
  a carbohydrates-to-protein ratio of 3-to-1 or
  4-to-1, Stager states.
• This ratio is what most sports drinks companies
  strive for in their products but chocolate milk
  has this ratio naturally!

6

• Since sports drinks have the same ratio of
  carbohydrates and protien than why did milk
  perform better?
• Researcher Jeanne D. Johnston, MA, told WebMD it
  may have to do with the different composition of
  the sugars in the milk.
• Another theory is that the sugars in the milk may
  be better absorbed in the gut than those in the
  Endurox.

7
Milk is superior!

• Chocolate milk is a cheaper alternative for
  expensive sports drinks and more commonly
  available.
• The protein in milk is high quality, which means
  it contains all of the essential amino acids or
  building blocks of protein.
• Milk contains key nutrients, such as calcium and
  vitamin D, in quantities that sports drinks cant
  match.

Vitamins and Minerals

• Calcium helps build and maintain strong bones and
  plays an important role in muscle contraction.
• Vitamin D helps promote the absorption of calcium
  and enhances bone mineralization. Milk is one of
  the few dietary sources of this important
  nutrient.
• Potassium regulates the bodys fluid balance and
  helps maintain normal blood pressure. Its also
  needed for muscle activity and contraction. Milk
  provides 11 of the Daily Value of potassium.

9
Vitamins and Minerals

• Vitamin A helps maintain normal vision and skin.
  It also helps regulate cell growth and maintains
  the integrity of the immune system.
• Vitamin B12 helps build red blood cells that
  carry oxygen from the lungs to working muscles.
• Riboflavin, also known as vitamin B2, helps
  convert food into energy a process crucial for
  exercising muscles.
• Niacin is important for the normal function of
  many enzymes in the body, and is involved in the
  metabolism of sugars and fatty acids. A glass of
  milk contains 10 of the Daily Value for niacin.
• Phosphorus helps strengthen bones and generates
  energy in your bodys cells.

Something to keep in mind

• Replacement of energy stores is most important
  for competitive athletes who work out vigorously
  once or twice a day. -Roberta Anding, sports
  dietitian and spokeswoman for the American
  Dietetic Association.
• But it is important for everyone to get 3
  servings of dairy a day.
