Drowning

Question 16

Heat generated by exercise of short duration does not

Answer 16

Increase body temperature that much

Question 17

Under what conditions can sweating be effective?

Answer 17

Evaporate easily- if it is humid, it won’t happen, failure to maintain a stable body temperature

Question 18

Thermoregulation relies on

Answer 18

Heat

Question 19

How is thirst monitored in practice vs games?

Answer 19

Competitions have breaks where athletes can weigh and drink what is necessary; in practice, they rely on thirst.

Question 20

What is the key for prepping for extreme heat?

Answer 20

Train in the same environment and keep track of water intake and satisfaction

Question 21

What are the symptoms of a heatstroke?

Answer 21

Fatigue
Nausea
Mental confusion
Disorientation

Question 22

How is a heatstroke confirmed?

Answer 22

Rectal temp 41 degrees or more, cool subject and and provide fluids

Question 23

Answer 23

Peripheral vasoconstriction

Question 24

What is essential for preparing the body for training in the heat?

Answer 24

Heat acclimation, heat sessions of 40-100 minutes, intensity causes lots of sweating id enough to trigger adaptations

Question 25
