The response to exercise lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability class, although content can be adjusted to suit any ability. Includes powerpoint timers, slide animations, embedded video's and mini review. NB: If you are unable to play embedded videos please view slide notes for link.
AQA spec link: 4.4.2.2
Relevant chapter: B9 Respiration. AQA Biology third edition textbook-Page 136-137
Students are required to know the following;
During exercise the human body reacts to the increased demand for energy.
The heart rate, breathing rate and breath volume increase during exercise to supply the muscles with more oxygenated blood.
If insufficient oxygen is supplied anaerobic respiration takes place in muscles. The incomplete oxidation of glucose causes a build up of lactic acid and creates an oxygen debt. During long periods of vigorous activity muscles become fatigued and stop contracting efficiently.
AT 1, 3, 4 Investigations into the effect of exercise on the body.
(HT only) Blood flowing through the muscles transports the lactic acid to the liver where it is converted back into glucose. 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.
