Hydration
Lesson details
Learning outcome
I can state the effects of dehydration and evaluate the consequences of dehydration on sport performance.
Key learning points
- Dehydration occurs when there is an excessive loss of water which interupts body functions.
- Maintaining hydration helps prevent dehydration and its consequences.
- Dehydration thickens the blood, which slows blood flow.
- Dehydration leads to increased heart rate, overheating, slower reaction times and muscle cramps.
Keywords
Hydration - having enough water to enable normal functioning of the body
Dehydration - excessive loss of body water interrupting the function of the body
Reaction time - the time taken to initiate a response to a stimulus
Rehydration - consuming water to restore hydration
Viscosity - thickening of the blood
Common misconception
The main consequences of dehydration are headaches and dizziness.
Headaches and dizziness are likely effects of dehydration, however the GCSE specification expects students to be able to understand the physiological reasons behind these such as slow blood flow, increased heart rate and body temperature.
Teacher tip
The lesson is a good opportunity to review the ingredients of the products on the market for rehydration.
