11. 11Concepts of Physical Fitness 12e Benefits of a Cool-down  Reduces blood pooling  Promotes recovery  Minimizes muscle soreness

12. 12Concepts of Physical Fitness 12e Exercising Safely in Different Environments  Heat  Cold  Altitude  Pollution See Web03 for additional info about all of these environments

13. 13Concepts of Physical Fitness 12e Heat Related Illness  Heat cramps  Heat exhaustion  Heat stroke The severity of heat related illness increases with the degree of dehydration

14. 14Concepts of Physical Fitness 12e Exercise in the Heat  Avoid high heat/humidity  Replace fluids  Gradual exposure (acclimatization)  Dress properly  Rest frequently  Watch for signs See Web03-4 See Web03-5

15. 15Concepts of Physical Fitness 12e Exercise in the Cold  Wind-chill factor  Dress in layers See Web03-6

16. 16Concepts of Physical Fitness 12e Effects of Altitude  Lower partial pressure of oxygen leads to shortness of breath  Cold, dry air promotes dehydration  Acute mountain sickness See Web03-7
