preparation for training Flashcards
what fuels energy?
carbohydrates, proteins, fats, water minerals and vitamins
what are the 3 energy systems?
- ATP-PC system
- Lactic Acid/Anaerobic Glycolysis system
- Aerobic system
what is ATP made up of?
adenosine molecule and 3 phosphate groups
what is the ATP-PC system for?
for high intensity, short duration activity
what is glycogen?
an energy storage for glucose
when does the anaerobic glycolysis system take over?
when the ATP-PC system has run out of CP stores. approx 10 seconds to 60 seconds
what is the only fuel food that can be catabolised anaerobically?
glucose/carbohydrates
what is lactic acid?
a substance that accumulates in muscles when exercising intensely (above 85% maximal heart rate). it is what causes fatigue
what fuel is used in the ATP-PC system?
carbohydrates, fats, proteins
what fuel is used in the lactate/anaerobic system?
carbohydrates, glycogen
what fuel is used in the aerobic system?
carbohydrates, proteins, fats
ATP-PC maximal heart rate %?
95%-100%
Anaerobic/lactate system maximal heart rate %?
85%-95%
aerobic maximal heart rate %?
75%-85%
what are the health-related fitness components?
cardiorespiratory fitness anaerobic capacity flexibility muscular endurance strength body composition
what are the skill-related fitness components?
speed power coordination balance agility reaction time
what are fast-twitch fibres used for?
they are used for short, powerful bursts of energy
