Investigating Breathing Rate & Heart Rate Experiments - Biology - GCSE / IGCSE - Exam Revision Notes
This PDF will discuss the following: -Investigating the breathing rate & heart rate experiments -Why is there an increase in breathing and heart rate during exercise? -Which controls have to remain constant during this experiment? -Exercise increases heart rate Questions and Answers are also displayed in this PDF: Suggest why the mean value of heart rate just before exercise is different to the mean value at rest rate. Long distant runners and cyclists usually have a lower than average heart rate. Suggest why a low heart rate has developed in these people. Some athletes preparing for long distance races, train at high altitude levels for several weeks. The availability of oxygen at high altitude is lower so the body responds by increasing the number of red blood cells. The number of red blood cells remain high when the athletes return to lower altitudes to compete. Explain why having more red blood cells is an advantage to athletes who take part in long distance races. Explain why long distance athletes who train at high altitudes have a better chance of winning , compared to long distance athletes who compete at sea level.
