What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents

is to find out and measure the effect of exercise on the respiratory system. I predict that whilst carrying out the exercise‚ the breathing rate will considerably increase from resting to working breathing rate. However due to the fitness of the volunteer this breathing rate could be different. As soon as the volunteer has stopped the exercise‚ I predict that the breathing rate will steadily decrease over a number of minutes until it gets back to resting breathing rate. I can justify my prediction

1. The heart rate determines the intensity of the fitness activity. a. 12*6=72 b. 220-21=199 c. 129-150 range. 2. Aerobic metabolism‚ uses fats‚ proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism‚ uses only carbohydrates and enters the fluid‚ or cytoplasm‚ of the cell and is turned into lactic acid. Aerobic exercises are running‚ biking‚ and swimming‚ whereas anaerobic exercises are sprinting‚ jumping‚ weight training. 3. My activity is considered

does exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up. His heart rate

if the heart and breathing rate will increase during exercise. It was hypothesised that if the amount of exercise (independent variable) increases‚ then the individual’s heart rate (bpm) and breathing rate (breaths-pm) (dependant variables) will increase when the environment in which the exercise is completed and a consistent and appropriate method of measurement for the dependant variables are kept constant. It was hypothesised that if physical exercise was increased‚ an individual’s heart and breathing

Introduction: Heart Rate is defined as the amount of times a person’s heart beats in one minute. A resting heart rate is the person’s heart rate prior to any activity or exercise. As activity increases‚ the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and arteries

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

Improvements 6 The effect of exercise on the heart rate and breathing rate Introduction Aim: Finding out how exercise affects the heart rate and breathing rate. Hypothesis: Exercise exists in different forms and has many benefits; it improves the oxygen-carrying capacity of the blood‚ development of bones‚ strengthens muscles and the lungs capacity plus it can make you feel good. There are different exercises and intensities for different benefits. Lower intensity exercises are not designed to

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They
