HSC PDHPE Option 3: Environmental Considerations in Sports

What is the primary method the body uses to regulate temperature?

• Evaporation

• Radiation

• Conduction

• Convection

What is the effect of wearing black clothing in the sun?

• Decreases body temperature

• Increases radiation absorption

• Prevents sweat evaporation

• Has no effect on body temperature

Which combination increases the risk of hypothermia?

• Rain and cold

• Cold and wind

• Heat and humidity

• Heat and wind

What is the effect of high humidity on the body's cooling process?

• Increases evaporation rate

• Decreases sweat production

• Makes evaporation less efficient

• Enhances conduction

What is the main risk when combining heat and humidity in sports?

• Hyperthermia

• Hypoxia

• Hypothermia

• Dehydration

What is a key strategy to prevent hypothermia in cold and windy conditions?

• Exercising indoors only

• Avoiding hydration

• Wearing light clothing

• Drinking warm water

Which clothing choice is recommended for cold and windy conditions?

• Windbreaker

• Shorts and t-shirt

• Ice vest

• Light breathable clothing

Which strategy is NOT effective against hypothermia?

• Staying dry

• Avoiding wind exposure

• Wearing snow gear

• Drinking cold water

How does altitude affect athletic performance?

• Lowers oxygen concentration

• Improves temperature regulation

• Increases oxygen concentration

• Decreases risk of hypoxia

What is the purpose of acclimatization in sports?

• To increase muscle mass

• To adapt to environmental conditions

• To improve agility

• To reduce oxygen needs
