Background
----------
Respiration is the process of converting glucose into energy; it is
not breathing in and out, as is often believed. Energy is needed for
growth, repair, movement and other metabolic activities. The energy
released from glucose in respiration is used to produce the chemical
adenosine triposphate. Adenosine triposphate is where the energy
released during respiration is stored for future use. Respiration
happens in every cell in your body.
There are two types of respiration; one is aerobic respiration. This
is what happens when there is plenty of oxygen. Aerobic power depends
on good lung function to supply oxygen to the blood, a strong heart to
pump blood to the muscles and the muscles must be efficient in using
the oxygen sent to them. The equation for aerobic respiration is:
Glucose + Oxygen àCarbon Dioxide + Water (+Energy)
The other type of respiration is anaerobic respiration. This is simply
respiration without any oxygen available. There is not nearly as much
energy produced as there is in aerobic respiration and it has the
ability to produce great force quickly with a combination of speed and
strength. Highly anaerobic activities use up energy so fast that they
can be sustained for only 30 seconds or less. This is how sprinters,
long jumpers and weight lifters use their energy, but if used by a
marathon runner for instance, there would soon be an oxygen debt.
Because of this oxygen debt, lactic acid builds up. Lactic acid is a
mild poison, which makes muscles feel tired and causes muscle cramp.
So, anaerobic respiration is best used for short, strenuous
activities. The equation looks like this:
Glucose àEnergy + Lactic Acid
Pulse rate is the number of times the heart beats per minute. It is
caused by a stretching of the arteries that takes place after each
heartbeat. Pulse rate is caused by the actual impact of blood on the
arteries.
Method
In this experiment I am hoping to prove that when using anaerobic
The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.
Cardiovascular Activity And How it Influences the body. Introduction: Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold.
To make sure it is a fair test; the procedure is repeated a couple of
In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.
In this lab we try and figure out the effects of exercise on cellular respiration, and identify a role of carbon dioxide production, breathing rate, and heart rate in determining the rate of cellular respiration. To do this we made a Phenol Red solution and used a straw to blow into it with no exercise to see how long it would take for the color of the Phenol Red solution to change, after this we measured our heart, and breathing rate. Then we did these same steps again after 1 minute, then another 2 minutes of exercising (Note: This lab was incomplete). The problem of this lab is “ How will carbon exercising, and increased carbon dioxide production affect the color of the Phenol Red, our heart rate, and our breathing rate. I hypothesize that if we exercise then we will affect our cellular respiration, and cause the Phenol Red to change color in a faster rate, because when we exercise we breathe heavily resulting in a higher carbon dioxide production which will cause the Phenol Red to change at a faster rate.
Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
The purpose of this lab was to determine the anaerobic power output capabilities of the legs and hips and to test the specific energy systems used during each exercise test. Anaerobic power is the rate of utilization of one anaerobic pathway and without the use of oxygen. During this lab, the Margaria-Kalamen Power test and Wingate cycling test will be used to determine power output capabilities. Power is a measurement of work. Power equals Force*distance divided by time. During anaerobic metabolism, oxygen is low at the level of the mitochondria, and only carbohydrates are being oxidized. There are three main pathways that can be used to generate
Aerobic capacity is a how well the body uses air or oxygen during a workout or exercise. Exercises that require lots of high-energy improve aerobic capacity by strengthening the heart muscle and improving the function of the rest of the cardiorespiratory system. Several people want to improve personal aerobic capacity levels. Once a person improves their aerobic fitness level their risk of high blood pressure, high cholesterol, type II diabetes, heart disease, and risk of obesity lower significantly. “The body undergoes multiple adaptations when continuously engaging in aerobic exercise. The heart, lungs, active muscles and circulatory system all undergo changes that are positive to your health. Popular forms of aerobic exercise include running, jogging, swimming, biking and circuit workouts. (Bradley, 2013)” Even though there are several ways to improve aerobic capacity, it really depends on the “FITT Principles.” The FITT Principles are frequency, intensity, type, and time of exercise se...

The Effect of Exercise on Pulse Rate What is a Pulse In Physiology, a pulse is where there is a recurring opening out of the biggest blood vessels (Arteries). This is a consequence of a coherent flow of blood being propel around the body. The muscle that is responsible for this surge of blood is the Heart. I know that by taking 220 and subtracting your age you can find your maximum pulse rate, because your muscles rely on oxygen it is important that I understand how oxygen is transported to the bodies cells.
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
Aerobic exercise involves improving the cardiovascular system. It increases the efficiency with which the body is able to utilize oxygen (Dintiman, Stone, Pennington, & Davis, 1984). In other words, aerobic exercise means that continuous and large amounts of oxygen are needed to get in order to generate the amount of energy needed to complete the workout. The most common type of aerobic exercise is long-distance running, or jogging. While running, the body requires large amounts of energy in order for the body to sustain energy. “During prolonged exercise, most of the energy is aerobic, derived from the oxidation of carbohydrates and fats” (Getchell, 1976).
