Wayne has to keep his blood full of oxygen… because they need to respire faster and release energy more quickly. When Wayne starts to run his muscle cells need more oxygen… because his blood could run low on oxygen so his lungs try to move air in and out faster. Wayne’s lung volume is normal but if the volume breathed out in 1 sec drops... because his lungs can’t move air in and out any faster so it feels as if he can’t breathe. Sometimes this can be a bit scary for Wayne… because his body cells would die if they couldn’t get oxygen from his blood. Wayne’s Breathing Problems TestValue Lung volume 5 ½ litres Volume of air breathed out in 1 sec 4 ½ litres Results from a similar athlete: 1Are Wayne’s results higher or lower than the other athlete? 2Does this provide evidence that Wayne has difficulty in breathing? 3If Wayne was struggling to breathe when he raced, which result would be different and which the same?

True Wrong! No energy, no work.Muscles need energy to work.Right! No energy, no work. Right! Glucose and oxygen. Cells release energy from glucose and water. Wrong! Glucose and oxygen. Right! It’s respiration.Releasing energy is called perspiration.Wrong! Respiration. Wrong! 20% of air is oxygen.Oxygen for respiration comes from air.Right! 20% of air is oxygen. Wrong! You need energy to move. Our muscles need more energy when we exercise. Right! You need energy to move. Right! More energy, more oxygen. So they need less oxygen per second. Wrong! More energy, more oxygen. Right! We get more oxygen into our body by breathing faster and deeper. We get more oxygen into our bodies by respiration. Wrong! We get more oxygen into our body by breathing faster and deeper. Wrong! It’s our body telling us to breath more. If we can’t take oxygen in fast enough, we feel breathless. Right! It’s our body telling us to breath more. Wrong! That’s why Wayne has such good lungs. Fitness training makes our lungs more efficient. Right! That’s why Wayne has such good lungs. Right! It’s only the airways that are a problem, they can get very narrow. Asthma sufferers have weak lungs. Wrong! It’s only the airways that are a problem, they can get very narrow. Wrong! It restricts the air flow. If our airways are narrow it makes it harder to take air in fast. Right! It restricts the air flow. Wrong! Asthma need not interfere with fitness.Asthma medication can keep airways open.Right! Asthma need not interfere with fitness.
