less energy is given out than in aerobic respiration. If insufficient oxygen is supplied, anaerobic respiration takes place in muscles. The incomplete oxidation of glucose causes a buildup of lactic acid and creates an oxygen debt. Oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells. anaerobic respiration in animal cells. Describe and explain the changes that occur in the body during exercise. Design and carry out an investigation about the effects of exercise on the body. Present and interpret data heart rate, breathing rate and breath volume. Interpret data relating to the effects of exercise on the body, eg spirometer tracings. Describe the effects of long periods of vigorous exercise on the body. Define the term ‘oxygen debt’. compare rate of breathing before, during and after exercise. Use spirometer tracings to calculate breathing rate and depth of breathing. Interpret data on heart rate, temperature and depth of breathing during exercise. Interpret data to compare how fit different people are. Discuss causes and effects of muscle fatigue and relate these to lactic acid build up. a video showing sprinters and discuss how the body reacts at the end of the race – paying back the oxygen debt. YouTube has a variety of videos of marathon runners struggling over the finish line – use them as a discussion starter, eg: produce an article for a fitness magazine.
