pe- exercise physiology

Question 1

Conduction

Answer 1

Heat exchanged by 2 objects in contact

Question 2

Convection

Answer 2

Heat exchanged with a fluid that is flowing

Question 3

Radiation

Answer 3

heat exchanged from a warmer body to cooler surroundings without physical contact

Question 4

Evaporation

Answer 4

Cooling of the body as a result of the vaporisation of sweat

Question 5

Dehydration

Answer 5

When amount of water leaving the body exceeds the amount being taken in

Question 6

Double heat load

Answer 6

Where the body is forced to deal with two forms of heat, metabolic and environmental.

It creates comp for blood flow, reducing performance and blood is taken away from working muscles for evaporation, reducing performance.
Increased sweating= decreased BP volume; cardiac drift occurs

Question 7

Cardiac drift

Answer 7

Where HR increases to try to maintain cardiac output due to decreased SV, however Q is still reduced.

As result, skin blood flow reduced, less O2 sent to working muscles, placing extra strain on body to maintain exercise levels. Reducing blood flow to skin reduces sweating, increasing core temp, reducing performance
