Hypotonic drink
The energy used by the body to maintain essential functions while at rest.
Basal metabolic rate (BMR)
Minerals such as sodium and potassium that help regulate fluid balance and muscle contractions.
Electrolytes
The sugar found in fruit.
Fructose
A sports drink with a similar carbohydrate concentration to body fluids.
Isotonic drink
Substances found in foods such as berries and vegetables that help neutralise free radicals.
Antioxidants

Hyponatremia
A carbohydrate made up of many sugar molecules joined together.
Polysaccharide

Hypertonic drink
The balance between the energy consumed through food and the energy expended through activity and bodily functions.
Energy balance
The body's ability to maintain a stable core temperature of approximately 37°C.
Thermoregulation
The storage form of carbohydrate found in muscles and the liver.

Hypohydration
The process in which cells use glucose and oxygen to release energy.
Respiration
This type of sports drink is generally most suitable after prolonged exercise when energy stores need replenishing.
Hypertonic sports drink
Unstable molecules that can damage cells if they accumulate in large amounts.
Free radicals
