environmental considerations Flashcards
1
Q
Temperature Regulation
A
- Convection
- Radiation
- Conduction
- Evaporation
2
Q
Temperature Regulation: Convection
A
- Air or water passing over our body removing the heat as it goes
- Hot: Place athlete in front of fan, pouring water over skin
- Cold: Wearing windbreaker to prevent wind contact with body
3
Q
Temperature Regulation: Radiation
A
- Heat lost though electromagnetic waves
- Hot: Don’t expose skin to sun
- Cold: Expose skin to sun
4
Q
Temperature Regulation: Conduction
A
- Transfer of heat between two objects in contact with each other
- Bodies heat up due to creation of ATP which converts to ADP
- Hot: Skin contact with ice-vest
5
Q
Temperature Regulation: Evaporation
A
- Transfer of heat to sweat, resulting in vapour
- Hot: Drinking water assist body to produce more sweat
- Cold: Removing water with towel
6
Q
Climate Conditions
A
- Temperate
- Humidity
- Wind
- Rain
- Altitude
- Pollution Levels
7
Q
Climate Conditions: Hot Temperature
A
- High risk of hyperthermia
- Heat is waste product in ATP production
- Forces sweat to be produced and hence dehydration
8
Q
Climate Conditions: Cold Temperature
A
- Sweat less
- Prevented by wearing more clothes
- Constantly active
9
Q
Climate Conditions: Humidity
A
- Water concentration in atmosphere
- Less effective in removing sweat and heat
- Conduction can not occur due to hot surfaces
10
Q
Climate Conditions: Wind
A
- Warm wind will add heat to athlete
- Greater heat loss through convection
11
Q
Climate Conditions: Rain
A
- Increases heat loss due to convection of water on skin
- Humidity increases
- Slippery surfaces
12
Q
Climate Conditions: Altitude
A
- Higher the altitude, the lower the oxygen concentration
- Less molecules in high altitudes
- Greater radiation from sun
- Acclimatisation of oxygen intake
- LIVE HIGH TRAIN LOW
13
Q
Climate Conditions: Pollution
A
- Presence of contaminants in atmosphere
- Wearing mask
14
Q
Guidelines of Fluid Intake
A
- Sweat Rate
- Temperature
- Environment
15
Q
Acclimitisation
A
- Adjusting to change in environment
- 2 weeks
