The Effect of Exercise on Heart Rate
Introduction
This assignment is intended to determine what the effects of exercise
will have on your heart rate. We are going to do this experiment by
using a data logger to record the results we receive. This can then be
transferred to a computer and results can be made into graphs and
charts. A data logger works by first being connected to a computer.
Then software is used to select start times finish times and when to
take measurements. The logger is then disconnected and attached to the
person. The logger records each measurement and stores it in memory
along with the time. The logger is then reconnected to the computer
and the software is used to retrieve the data and see the measurements
as a graph, and charts. Data loggers are extremely efficient because
they are very small and usually battery powered for ease of use. The
exercise I will use will be a step-up machine, this is because it is
the most accurate way of exercise as it is at the same pace throughout
and can be kept at the same difficulty level.
As the body is exercising the cells need oxygen quicker therefore the
heart has to pump the oxygenated blood around the body quicker than
normal and this makes the heart rate increase.
Most cells in the body need oxygen to function correctly, when we
exercise the cells need more energy and oxygen so that the muscles
which help us to complete the exercise can move by muscle contraction.
The energy which we need for muscle contraction comes from food
molecules inside cells, this is a process which is known as
respiration. The main respiratory substance is glucose and the energy
released is used for the muscle contraction that we need to exercise.
When we do anything are body is releasing energy to help us to fulfil
what we are doing. Even the simplest actions need energy. When we
start to exercise we use aerobic respiration, this takes place in the
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 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.
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.
Currently, it is not possible to prescribe isometric exercise at an intensity that corresponds to given heart rates or systolic blood pressures1. This might be useful in optimizing the effects of isometric exercise training1. According to further study on this topic, linear relationships that have been discovered could be used to identify isometric exercise training intensities that correspond to precise heart rates or systolic blood pressures. Training performed in this way might provide greater insight into the underlying mechanisms for the cardiovascular adaptations that are known to occur as a result2. Studies have also shown a direct, strong, independent and continuous relation between blood pressure and cardiovascular mortality without any evidence of a threshold down to at least 115/75 mm Hg3. Further, it has been demonstrated that, as compared with optimal BP, normal and high-normal BP are associated with a higher incidence of CV disease3.

We see that to the left of the arrow that lactate levels, PaCO2, PaO2, and pH remain relatively constant while ventilation and carbon dioxide production rate increase nearly linearly. This is because during this phase aerobic respiration occurs and the closely related ventilation and carbon dioxide products rates allow the pressures to remain nearly constant. To the right of the arrow, anaerobic respiration occurs. During heavy exercise, the arterial pH levels decrease as lactic acid is produced by muscle during anaerobic respiration. The decreased pH stimulates ventilation that is out of proportion to the intensity of exercise. The increase in lactic acid leads to higher carbon dioxide production rates from the oxidation of lactic acid. Hyperventilation leads to lower arterial partial pressures of carbon dioxide since more carbon dioxide is lost in the lungs. The increase in arterial partial pressure of oxygen is because uptake of oxygen
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.
In this report, I will be writing about the data that was collected from the beep test, which tests the aerobic endurance of the participants who are performing the test. With the results collected I will be discussing the different factors that may have impacted on the participant’s results. Robinson (2010) states that there are different systems in the body such as the skeletal, muscular, circulatory, and respiratory. Despite the fact all these systems are separate, they are all linked together to help the functioning of the body when at rest and during exercise. When the body begins to participate in exercise, during physical activity changes start to occur in the cardiovascular system starts so that it can adapt to the physical activity, this links into Kenney et al, (2012) where they indicate that cardiovascular changes occur when the body starts to move during exercise, and that the main reason for this is so that the blood flow increases to the working muscles. Furthermore, there are other adjustments in the cardiovascular system, where the ‘blood flow patterns change significantly in the change from rest to exercise. Through the vasoconstrictor action of the sympathetic nervous system on local arterioles, blood flow is redirected away from areas where elevated flow is not essential to those areas that are active during exercise, only 15% to 20% of the resting cardiac output goes to muscle, but during high-intensity exercise, the muscles may receive 80% to 85% of the cardiac output.’ (Kenney et al, 2012:190)
body has to work harder I think that the heart will then increase at a
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 working cells. The hypothesis is accepted because the data collected supports the initial prediction. There is a relationship between the amount of time spent active and the speed of heart rate: as the amount of time spent active rose, the data displayed that the speed that the heart was beating at had also increased. This relationship is visible in the data since the average resting heart rate was 79 beats per minutes, while the results show that the average heart rate after taking part in 30 seconds of activity had risen to 165 beats per minute, which is a significantly larger amount of beats per minute compared to the resting heart rate. Furthermore, the average heart rates after 10 and 20 seconds of activity were 124 and 152 beats per minute, and both of which are higher than the original average resting heartbeat of 79.

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.
