Immediate and short term effects of exercise Effects of regular participation on the respiratory system The effects of smoking on the respiratory system Respiratory System
Respiratory system YtXc_84A (General) YtXc_84A 8Lw4q2Mk&feature=related (Children) 8Lw4q2Mk&feature=related In general: Air is drawn in through the mouth and in to the lungs. We breath in oxygen and breath out carbon dioxide in a process known as gaseous exchange.
Immediate effects of exercise Try it! 1.Quietly sit and put your head on the desk, count how many times you breathe in and out in 1 minute (in and out = 1 breath) 2.Now, do an aerobics session for 2 minute and re-count your breaths 3. Write down what differences you had
Immediate effects of exercise Increased breathing rate Increased depth of breathing Therefore….an increase in TIDAL VOLUME Tidal volume: the amount of air inspired and expired with each normal breath at rest or during exercise.
Immediate effects of exercise Oxygen Debt 1.What do you feel like after a hard run or match? 2.Have you noticed that you breathing doesn’t go straight back to normal? 3.Why do you think you body has to keep breathing fast and deep? What your experiencing is oxygen debt!!! Oxygen Debt: the extra oxygen consumed during recovery in comparison to normal after a period of strenuous exercise. e.com/watch?v=2f n8LZvsRhs
Vital Capacity Vital Capacity – the greatest amount of air that can be made to pass into and out of the lungs by the most forceful inspiration (breath in) and expiration (expiration). Can be affected by age, gender, size of chest, physical fitness, race and posture. Lets have a go….
The effects of regular exercise on the respiratory system 1.Vital capacity increases as the body becomes more efficient 2.More alveoli for gaseous exchange so more oxygen can pass in to the blood and carbon dioxide out 3.More capillaries for more oxygen to get in to the blood. Therefore: Carbon dioxide is removed more efficiently Oxygen is transported to the muscles more efficiently ** More efficient is the key word!
Smoking: Effects on the respiratory system Tidal volume decreases Vital capacity decreases Smoking damages the lungs especially the alveoli so they become less stretchy and less efficient. As a result it makes it more difficult for the body to remove carbon dioxide and take in oxygen.
Aerobic V Anaerobic Aerobic Creates energy with oxygen Sports such as: long distance swimming, marathon, cross country running. Or any part of an activity where intensity is low. Anaerobic Creates energy without oxygen Sport/activities such as: 100m sprint, long jump, kicking a ball, cycle sprint. Or any part of an activity where intensity is high Youtube: Olympics London 2012 best bits pick out examples.
