PE Textbook Content Flashcards
Energy
Power derived from fuels
Fitness
The state of being physically fit
Training
Tasks to enhance energy and fitness
Carbohydrates
Stored as glycogen, easy to break down, ideal energy source, up to 120 minutes of exercise
Proteins
Essential amino acids - cannot be made by body
Non-essential amino acids - made by body
Used for growth and repair, last resort energy choice
Fats
Essential fatty acids - cannot be made by body
Non-essential fatty acids - made by body
Requires time and oxygen to break down, low to moderate intensity activities
ATP
Adenosine triphosphate - high energy bond breaks and provides heat and energy (becomes ADP) cyclical
ATP-PC system
Maximum intensity, short duration
10-15 seconds
2-3 minute recovery
Lactic acid system
Medium-high intensity, short duration
60-90 seconds
Aerobic system
Low intensity, long duration
infinite
Components of fitness
(Some Silly Aardvarks Found Massive Ant Pants)
Strength
Speed
Aerobic capacity
Flexibility
Muscular endurance
Agility
Power
Strength
ability for muscles to exert force against resistance
Speed
ability to move quickly
Agility
ability to move in different directions quickly and accurately
Muscular endurance
ability to sustain repeated muscle contractions
Flexibility (component)
ability to move through a full range of motion
Aerobic capacity
ability of heart, lungs, and circulatory system to supply oxygen and nutrients to body
Power
ability to exert maximum force quickly
Tapering
gradually reducing work volume and intensity in the lead up to competition
Training zones
determines upper and lower limits of intensity for training, % of heartrate
Periodisation
dividing a larger period of training time into smaller periods (annual plans, macrocycles, training phases, mesocycles, microcycles, training sessions)
Recovery training zone
> 65% MHR
Aerobic training zone
60-80% MHR
