PROCESSING THE DATA-
FINDING THE AVERAGE BREATHING RATE AFTER EACH EXERCISE-
AVERAGE BREATHING RATE AFTER EACH EXERCISE PERIOD-
? 0 Minutes of exercise (Resting phase)- = 19 Breaths/minute
? 2 Minutes of exercise- = 27.75 Breaths/minute
? 4 Minutes of exercise- = 35.25 Breaths/minute
? 6 Minutes of exercise- = 43.25 Breaths per minute
STANDARD DEVIATION-
? 0 Minutes of exercise
22- 19 = 3^2= 9
18- 19 = -1^2= 1
16- 19 = -3^2= 9
20- 19 = 1^2= 1
? (9+1+9+1)/4 = 5
? 2 Minutes of exercise
30- 27.75 = 2.25^2= 5.0625
28- 27.75 = 0.25^2= 0.0625
27- 27.75 = -0.75^2= 0.5625

Does the amount of exercise have an effect on the pulse rate?

1287 words - 5 pages PlanningThe aim of this experiment is to see if the amount of exercise has an effect on the pulse rate. I predict that the more exercise that is carried out will increase the pulse rate. I think this because the increased amount of exercise you do and as the more and more the muscle cells become engaged in doing work, the demand for ATP (The energy used by the body is always in the form of ATP) increases. Which means the demand for oxygen and

Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis

866 words - 3 pages Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The

Lab Report: The Stroop Effect

741 words - 3 pages Introduction.The 'Stroop Effect' was first introduced in 1935. It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice eg. Typing, driving, etc. Automatic processes therefore are fast, require no attention and are unavoidable. Stroop believed that there was some evidence that word identification may be a form of an automatic process. In the experiment

1837 words - 8 pages potential power output rate is the biggest. This system is considered anaerobic, as it does not need oxygen to resynthesize. It uses creatine kinase enzyme to control the breakdown of phosphocreatine (PCr). It is most useful when doing short-term, an intensive exercise that needs a large amount of energy to be produced. It is the fastest system to resynthesize ATP (Robergs & Roberts 1997). If exercise carries on, the body would have to rely on

The effects of physical activity on heart rate and breathing rate

701 words - 3 pages Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise, we measure the breathing rate

Investigating The Effect Of Exercise On Pulse Rate

834 words - 3 pages Investigating the Effect of Exercise on Pulse Rate Aim: To see what happens to the pulse rate during exercise. Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon

Heart Rate Lab Report

1401 words - 6 pages The purpose of this experiment was to gather data on how the amount of time spent active impacts the speed of heart rate in beats per minute. The hypothesis stated that if the amount of time active is lengthened then the speed of the heart rate is expected to rise because when one is active, the cells of the body are using the oxygen quickly. The heart then needs to speed up in order to maintain homeostasis by rapidly providing oxygen to the
