Includes a section for prediction, method, results and conclusion. During exercise, your breathing rate increases, and you also take in more air with each individual breath. The human respiratory system is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen. When you exercise, your breathing rate and pulse increase because your body needs oxygen. CB 6 Effects of Exercise on Pulse and Breathing Rates Your body is always adjusting to changes that take place in your activity or conditions in the environment. The metabolic byproducts of exercise build up as a result of cellular respiration, and the amount of carbon dioxide (CO2) in the system also increases to act as a buffer against these acidic byproducts. What does this extreme example tell us? The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled). As it was a beautiful autumn day in Shanghai we took the opportunity to use the sports field to do star jumps for 4 minutes and then measure how long it took the students breathing rate to return to normal. your heart rate increases, and your breathign increases to it. In addition, extreme temperatures can interfere with your circulation and make breathing difficult, and can cause chest pain. Working muscles also require fresh oxygen. Heart and breathing rates at rest and after exercise vary depending on your cardiovascular fitness. Quite simply, the more restrictions you place on your breathing, the harder it becomes. This lab will address how exercise (increased muscle activity) affects the rate of cellular respiration. Pulse rate is an indication of your heart rate as your arteries expand each time the ventricles pump blood out of the heart. When you exercise, your breathing rate increases to compensate for the increased need of oxygen that is required for your body to release energy. Vigorous energy generation in muscles brings about an increase in the gas exchange rate in the lungs since more oxygen is taken in and more carbon dioxide is discharged. Mr Gaynors Class. The pH of the blood is normally 7.35 to 7.45 – a narrow range. If the exercise is intense, breathing rates may increase from a typical resting rate of 15 breaths per minute up to 40 – 50 breaths per minute. The rate of breathing can be measured by counting the number of breaths in one minute. This could lower the pH (making the blood more, increases in the rate and depth of breathing speed up the rate at which carbon dioxide is removed from the bloodstream, Home Economics: Food and Nutrition (CCEA). more than they do when the body is at rest.
