Chemistry of Sports Drinks
what are sports drinks?
beverages that are rich in carbohydrates and electrolytes
main purpose is to assist in re-hydration during and after exercise
contains high percentage of sugar to restore energy
Types
3 Main Categories:
Isotonic
Hypertonic
Hypotonic
Isotonic
most common types of sports drinks
contain almost equal concentrations of salt and sugar
replace fluids and nutrients lost through sweating
preferred choice by athletes
electrolytes and 6 to 8% carbohydrate
Hypertonic
supplement daily carbohydrate intake and top up muscle glycogen store
contain a higher concentration of salt and sugar
preferred for high energy demands
high level of carbohydrate
Hypotonic
substitutes fluids lost by sweating
contain a lower concentration of salt and sugar
preferred by gymnasts or athletes
electrolytes and a low level of carbohydrate
History...
Players were affected physically
Fluids and Electrolytes were not being replenished
Gatorade was created
How are Sports Drinks made today?
Three main components:
Fluids (ex. water)
Electrolytes (ex. sodium)
Carbohydrates (ex. glucose)

How electrolytes are Formed?

Electrolytes are created when compounds, mainly salts are dissolved in water. A dissociation reaction occurs which results in the compound breaking apart, for example: NaCl → Na+ + Cl-

This is the creation of the electrolytes

Why are Electrolytes important?
Affect the amount of water in the body
pH levels
Helps body send signals from one cell to another
Different types of electrolytes: Sodium, Potassium, Chloride, Bicarbonate, Calcium, Sulfate, Magnesium, and Phosphate
Loss of electrolytes can cause cramping
Carbohydrates
Important energy source
Commonly used
Muscle contractions are possible
30-90 minute usage
Simple and Complex sugars
pH Levels
Distilled Water/Neutral =

7.0
Gatorade =

3.3
Powerade =

2.7
Sports Water =
8.0

Benefits on consumers
Replaces loss of sweat
Assist in proper muscle contraction
Provide energy
Quick source of carbs


Effects on Consumers

Rehydrate athletes
Digestive distress
Extra calories and sugar
Significance to Society

Can replenish needed electrolytes, improving athletic performance
can be used to keep sick people healthy by maintaining hydration.
