FAP: How does training affect performance? Flashcards
Factors Affecting Performance
what are the three main energy systems
alactacid or ATP/PC
lactic
aerobic
what form does the body require energy to be
adenosine tri-phosphate (ATP)
what is the ATP/PC systems source of fuel
ATP that is immediately available within the muscle, which reacted with creatine phosphate (CP)
what is the efficiency of ATP production
not very efficient, as it has a very limited store of fuel.
it quickly runs out
what is the duration of the ATP/PC system
8-12 seconds
what is the cause of fatigue when using the ATP/PC system
the depletion of fuel
what are the byproducts of the ATP/PC system
heat
how long does it take for the ATP/PC system to recover
2 minutes
what are examples of events using the ATP/PC system
100m sprints, Powerlifting, or throwing events such as the Javelin, Shot Put, or Discus throw
what is the lactic acid systems source of fuel
carbohydrates
what does the lactic acid system rely on for production of adenosine triphosphate
anaerobic glycosis
what is the lactic acid systems efficiency
produces ATP at a fast rate, with high quantities
how long can the lactic acid system last for
30seconds-3mins depending on intensity.
what is the lactic acid systems cause of fatigue
build up of pyruvic acid in the muscle
without oxygen, the body converts pyruvic acid into lactate
what is a by product of the lactic acid energy system
pyruvic acid
how long does it take for the lactic acid system to recover
30 min-1 hr
what events would use the lactic acid system
200m or 400m run, or 50m and 100m swim
are the lactic acid and ATP/PC energy systems anaerobic or aerobic
anaerobic
what is the aerobic energy systems source of fuel
it uses carbohydrates first, then fat, then protein as a last resort
how efficient is the aerobic system
very efficient, producing 38 ATP molecules per glucose
rate of production is medium
how long can the aerobic system last
technically it is limitless, as long as fuel sources are available
however, muscle glycogen depletes after an hr of exercise
what is the aerobic systems cause of fatigue
fatigue occurs after the carbohydrate stores have depleted
what are the byproducts of the aerobic system
water, carbon dioxide
the water can build up in the muscle and cause stiffness
how long is the rate of recovery for the aerobic system
12-24 hrs
