equation for aerobic resipration
glucose + oxygen –> carbon dioxide + water
equation for anaerobic respiration
glucose –> lactic acid)
what is aerobic respiration
respiration that takes place in the presence of oxygen
what is anaerobic respiration
process of converting glucose into energy without oxygen
what type of activity suited for aerobic respiration
• long duration • low intensity
what type of activity is suited for anaerobic respiration
• short duration • high intensity
what is EPOC
• excess post-exercise oxygen consumption • caused by anaerobic exercise producing lactic acid • continuation of high BR/HR to remove lactic acid
explain factors affecting recovery time
• overall strength and fitness: stronger muscles = quicker at absorbing o2 needed to remove lactic • genetics: inherit ability to recover quickly from parents • age: as get older, recovery time increases • gender • sleep: good sleep helps body recover mentally and physically
short term effects of exercise
• BR increase • HR increase • red skin / heat control / sweating • fatigue • nausea • light-headed
long term effects of exercise
• heart size increases (hypertrophy) • resting pulse rate decreases (bradycardia) • stroke volume increases • ability to tolerate lactic acid increases
