Lesson Summary
You will learn to state the effects of dehydration and evaluate the consequences of dehydration on sport performance.
Key Notes
- 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.
Vocabulary To Learn
- 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
