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.`
Hitting the wall`
When muscle glycogen is depleted
Boonking
When the liver and muscle glycogen is depleted
glycemic index
Ranking of carbohydrates based on their immediate effect on blood glucose levels
ergogenic aids
Any practice or substance, illegal or legal, used to improve performance
Specificity
Specifically developing energy systems which fuel the components of fitness to improve performance
Periodisation
Breaking a programme up into smaller blocks of time which have specific goals and objectives
Overtraining
Physiological, psychological, behavioural and emotional condition when exercise exceeds recovery
Recovery
Returning athletes to a state of physiological and psychological performance ready for training
Tapering
Involves decreasing volume, howver maintaining or increasing intensity to allow body to recover from the stresses placed on during training.
Peaking
Is the planning of training to optimise performance at appropriate times
Injured Athletes
The rehabilitation and recovery, opportunities to participate and to gain a sense of belonging amongst the group.
maintenance
Preserving fitness by ensuring recovery is reached, whilst a taper is carefully considered
Macrocycles
A large block of time in a programme, 3-12 months in length however can be longer
Mesocycles
Smaller blocks of time which form a macrocycles, 4-12 weeks in length.
Microcycles
Smaller unit which makes up a mesocycle, usually a week in length.
