what is aerobic respiration
respiration that takes place in the presence of oxygen
what is the equation for aerobic respiration
glucose + oxygen –> carbon dioxide + water
what is anaerobic respiration
respiration that takes place in the absence of oxygen
what is the equation for anaerobic respiration
glucose –> lactic acid
what kind of activity requires aerobic respiration
long duration, low/moderate intensity
what kind of activity requires anaerobic respiration
short duration, high intensity
how does EPOC work
• excess post-exercise oxygen consumption • caused by anaerobic exercise producing lactic acid • high breathing rate and rapid HR to remove lactic acid
what are the factors affecting recovery time
• overall fitness • genetics • age • gender • sleep
what are the short term effects of exercise
• HR increases • breathing rate increases • red skin/sweating (heat control) • fatigue • nausea • light-headedness
what are the long term effects of exercise
• increase in heart size (hypertrophy) • lower RHR (bradycardia) • increased stroke volume • higher lactic acid tolerance
