PE - respiration Flashcards
(14 cards)
immediate effects of exercise
*during exercise
- increased heart rate
- increased stroke vol
- increased body temp
- shortness in breath
short term effects of exercise
*up to 36 hours after exercise
- tiredness / fatigue
- light-headedness
- naesea
- DOMS
- cramps
long term effects of exercise - examples
*months / years of exercising
- body shape may change
- improved COF
- improve stamina
- increased stroke vol (more blood per beat)
- tolerance to lactic acid (delays fatigue)
- lower resting heart rate (bradycardia)
- increase in the size of the heart (hypertrophy)
aerobic energy system - definition
uses oxygen to produce energy (ATP) for longer, sustained activities
aerobic energy system - facts
- long, low intensity exercises
- requires continuous oxygen intake to maintain energy production
- endurance > intensity
aerobic energy system - examples
- long-distance running
- steady-pace swimming
- long cycle rides
- waking
- dancing (endurance)
aerobic respiration - formula
glucose + oxygen => carbon dioxide + water + energy
anaerobic energy system - definition
produces energy without the need for oxygen
anaerobic energy system - facts
- short, high intensity exercises
- buildup of lactic acid = fatigue & EPOC
- doesn’t required oxygen during activity
- max energy in short period of time
anaerobic energy system - examples
- sprinting
- weightlifting
- jumping
anaerobic respiration - formula
glucose => lactic acid + less energy
EPOC - definition
- excess post-exercise oxygen consumption
- amount of oxygen your body needs right after exercise to return to its resting state
- also known oxygen debt
EPOC - facts
- happens after every anaerobic exercise
- takes in extra oxygen
- to remove lactic acid
- to replace used energy
- slow heart rate / return body to rest
factors affecting recovery - EPOC
- fitness levels
- intensity of exercise
- nutrition
- hydration
