Environmental conditions Flashcards
Conduction
Heat is transferred by 2 objects in contact
Convection
The transfer of heat by the contact with a fluid that is flowing
Radiation
heat is transferred through electromagnetic rays
Cardiovascular Drift
When heart rate increases, due to decrease in stroke volume in an effort to maintain cardiac output
Dehydration
Occurs when fluid loss is greater then fluid gain
Double heat load
when body must cope against 2 forms of heat, metabolic and environmental
Heat exhaustion
Dehydration + Ineffective circulatory system.
Heat stroke
Sever dehydration and a dangerous rise in core temp.
Diffusion
Is the movement of liquid or gas across a semi-permeable membrane from an area of high pressure to low pressure.
Altitude Acclimatisation
Describes the improved physiological response to altitude hypoxia
Live High, Train High
A type of altitude training where the athletes live and train and a high altitude.
live high train low
A type of altitude training where the athletes live at a high altitude (Altitude Tent), However trains at sea level.
Train High, Live low
Athletes trains at altitude (Altitude chamber) However lives at sea level.
Glycogen sparing
Ability for an athlete to spare glycogen by using an alternative fuel source during physical activity.
carbohydrate loading```
Nutritional intervention aimed at delaying the depletion of glycogen stores.`
