Electrolyte Challenge
Problem: Can You Make a Homemade Sports Drink that is Healthier than the Drinks in the Stores?
Kids are drinking sports drinks to maintain electrolyte balance which are very unhealthy because they are full of dyes, flavorings, high fructose corn syrup, and lots of sugar! Some even have caffeine! The purpose of our experiment was to find an alternative for the bad-for-your-body sports drinks using easily obtainable ingredients that can be combined to have the same amount of, if not more, electrolytes.
Procedure:1. Pour ½ cup of sports drink into the basin labeled Sports Drink.
2.Turn multimeter on to the ammeter setting. 3. Place the straw into the Sports Drink basin. 4. Read and record the number of milliamps on to the recording sheet. 5. Rinse the straw with DH2O 6. Pour ½ cup of Orange Juice into the basin labeled Orange Juice. 7. Repeat steps 3 and 4 with the orange juice. 8. Fill up the basin labeled IKEade with ½ cup water. 9. Fill up the basin with the ½ cup of H2O, 10. Add orange juice tablespoon by tablespoon one at a time. 11. Place the straw into the IKEade basin after each tablespoon. 12. Record the number of milliamps on to the recording sheet. 13. Keep repeating steps 9, 10 and 11 until you reach the same, or above, number of milliamps as the Sports Drink. Results:

The Science Behind It:
We need electrolytes to ….
● carry impulses along our nerves ● help the muscles contract and relax ● keep the body from becoming too acidic or too basic ● helps regulate blood pressure ● helps regulate heartbeat What happens if you don’t get your electrolytes ??? ● dehydration ● muscle cramps ● muscle fatigue -Electrolytes separate into charged particles called ions when dissolved into water. -Positively charged electrolytes are called cations. Some examples of cations are ... ● sodium ● potassium ● magnesium ● calcium |

Sweat
-Sweat is more than just water. It has a lot of electrolytes too like sodium, potassium, calcium, and magnesium. -You lose an average of 1-4 pounds of sweat per hour depending on your … ● body size ● sport ● intensity ● how well you are trained ● genes ● diet |
Sodium | Potassium | Calcium | Magnesium | |
---|---|---|---|---|
Amount of loss in sweat | 800mg | 200mg | 20mg | 10mg |
Range of number of electrolytes lost in sweat | 200-1600mg | 120-600mg | 6-40mg | 2-18mg |
As you see, sodium is the electrolyte with the most loss, and should be replenished.
What You Want to Look for in the Sports Drink You Buy...
● Good taste (if the taste is good, you will tend to drink more)
● Carbs (supplies energy for muscle contraction)
● Sodium (sodium chloride is table salt. If you notice yourself getting thirsty, that is because sodium triggers thirst. If you have a lot of sodium, you will drink more [which is good when you are exercising])
What you DO NOT want to see in the sports drinks you buy...
● caffeine (can cause anxiety and irritability)
● vitamins ( not absorbed quickly enough to be of any significance)
● herbs (like ginsing) (inadequate data available)
● carbonation (causes you to bloat)
● plastic bottles (not environmentally friendly)
The American College of Sports Medicine recommends the sports drink to have …
● 110-170 mg of sodium per 8 ounce
● 20 -50 mg of potassium per 8 ounce
● 1200-2400 mg of carbohydrates per 8 ounce
