- Sports drink dilemma
- How do they differ from regular drinks?
- Soft drinks contain the necessary mineral ions and water etc, however they are not the right concentration. Sports drinks have just this and dilute body fluids, so water moves into the cells by osmosis.
- Some soft drinks will replace water if its only light exercise (up to an hour) and dilute orange squash with a pinch of salt can replace mineral ions
- What effect do they have?
- Regulates body temperature.
- Enables us to keep on exercising.
- Replaces water to absorb nutrients.
- Keep lungs moist to breathe
- Gives us more energy from carbohydrates and sugars. Keeps sugar levels high
- Why do we need them when exercising?
- When exercising our body uses energy from glucose to make our muscles contract. This generates heat, in which our body responds to by sweating to cool us down and keep our body at a regular temperature.
- When we sweat we lose ion minerals (e.g. sodium) and water, which causes a ion/water imbalance. Losing ions affects the concentration of fluids in our body and cause our cells to become concentrated. Water will then move out of the cells by osmosis and result in dehydrated cells.

- What is a sports drink?
- Sports drink contain mainly 4 ingredients: Caffeine, water, carbohydrates and miner ions. It is key to rehydrate muscles, replace lost energy and electrolytes.
- Different types of sports drinks.
- Isotonic- both concentration are equal
- Hypotonic
- hypertonic
