Exceecise Flashcards
What increases when exercising
Breathing rate increases
Breathing deeply
Increases heart rate
What happens when you excercise
Muscle cells needs more oxygen and glucose
Extra carbon dioxide needs to be removed from muscles cells
For these things to happen blood has to flow at a faster rate
What do muscles cells use oxygen for
Release energy from glucose to respire aerobic ally
What do your muscles store glucose as
Glycogen
Why is glycogen used
During hard exercise muscles use glucose quickly glycogen can be changed back to glucose to give more energy
What happens when you do hard exercise
Body can’t supply enough oxygen to your muscles this means the start respiring anaerobic ally
What is anaerobic respiration
Respiration without oxygen
Why is anaerobic respiration bad for converting glucose into oxygen
It makes lactic acid. The lactic acid builds up in your muscles and it is painful. It also causes muscle fatigue
What does muscle fatigue cause
Muscles to get tired and stop contracting a swell
