A year 11 student is participating in the beep test and is currently at level 8, discuss the immediate physiological responses that she is experiencing.
HIGHLIGHT SYLLABUS POINTS

The five immediate physiological responses to exercise are heart rate, stroke volume, cardiac output, ventilation and lactate levels. These five physiological responses change during different levels of exercise and are different pre and during exercise. The responses vary for different levels of fitness and capability. In this situation, for a year 11 student participating in the beep test currently at level 8, this person is under the average of 9 and will need to train to improve her level. This person will take part in aerobic training and this is where the physiological responses are undertaken. Also the FITT principal comes into account when relating to physiological responses.
Heart rate is the amount of times the heart beats per minute. There are three different types of heart rate, which include; resting heart rate. This is your heart rate when we are completely at rest. Working heart rate is when our heart rate is increasing with exercise and will increase according to the exercise. And steady state is when a fit person’s heart rate levels off during lengthened exercise. When our heart rate increases, the increase of the volume of blood is pumped with each contraction. This occurs because our muscles need more oxygen to contract so more blood needs to travel to the muscles. For example, as this person progresses through the levels, the intensity of the beep test will increase and therefore her heart rate will progressively increase. The time between levels will also increase and therefore the student heart rate will intensify.
Stroke volume is the amount of blood ejected by the left ventricle of the heart during a contraction. In similar terms, it is the amount of blood…...

Physiological Changes

...------------------------------------------------- Top of Form Bottom of Form Other Free Encyclopedias » Medicine Encyclopedia » Aging Healthy - Part 3 Physiological Changes age aging differences aging age disease deterioration Ads by Google It is evident even from casual observation of physical activities, such as walking, that elderly people exhibit a deterioration of physiological processes. Moreover, the inability of athletes to continue peak performance when they reach their thirties or forties indicates that deterioration begins at a relatively young age and progresses in severity from that point on. Indeed, many studies have confirmed that most physiological processes deteriorate progressively after about thirty years of age, some functions more severely affected than others. Most of the research on age-associated physiological deterioration has utilized cross-sectional studies; that is, subjects of different ages are studied at a given point in time (e.g., the calendar year 1990). These are called cross-sectional studies because the data are collected from a cross section of the population. Since this study design provides information quickly and relatively inexpensively, it is widely used. However, because of generational factors and selective mortality, the cross-sectional design can yield erroneous information about aging. An example of how a generational factor may confound an aging study is illustrated by a hypothetical 1970 cross-sectional study......

Physiological Effects of Blood Doping

...and that it was extremely harmful to the body. He became outraged when he caught wind that two of his cyclists received tainted blood and contracted hepatitis. He felt helpless in the situation because had he spoke out about it, he was would have just destroyed the entire team. In the late 1980s, medical and technological advances led to an entirely new form of blood doping, which involved the use of erythropoietin (EPO) injections. Many athletes began switching from transfusions to EPO injections because they were believed to be less dangerous. EPO is a naturally occurring growth hormone that is released from the human kidneys which acts on bone marrow to stimulate red blood cell production. Naturally, the kidney secretes EPO in response to the lack of oxygen going to the tissues. For example, people living in higher altitudes are going to have higher levels of EPO in their bodies. The excess oxygen going to the muscles explains why extra EPO is so beneficial to endurance athletes. Although, it was perceived to be a safer alternative to transfusions, EPO still poses major health risks. When injected into the body, red blood cell volume can increase up to 70 percent, which can have many adverse effects. It can cause blood to thicken, and blood flow to decrease, which will further increase the chances of blood clot development. And if blood clots develop in the head, then strokes are very likely to occur. But also athlete’s can experience this exact same effect......

Physiological Explanation

...Why it works – Physiological explanation Being in this industry, especially when promising results in 45 minutes, is skeptical to some people. I wanted to share this information with you guys to help you become more “credible” to those skeptical costumers out there that want a more in depth explanation of why and/or how it works. I recently received my Master’s in Exercise Physiology and actually specialized in Bioenergetics…so this is right up my ally!...I love anything having to do with Bioenergetics and Metabolism. So why does this product work for both men and women?....and just like anything else why do men tend to lose more or have better results? It simply has to do with our fat patterns, women have a gynoid fat pattern (pear shape), where as men have an android fat pattern (apple shape). As we know it, men will always have greater and faster results than women; this is due to their fat pattern. Android (men) fat pattern is easily broken down and mobile (which is why men tend to have higher rates of heart attacks because their fat is so mobile). On the other hand, Gynoid (women) fat pattern is “stubborn” so to speak, which means it is hard for women to break down fat as efficiently as men. With that being said this product is great for everyone, women in particular, because this product simply helps to speed up the process at which fats/toxins gets moving and utilized through Beta Oxidation…which would be known as a catalyst ….if we want to sound scientific to our...

Physiological Training

...Physiological Training Research In baseball we can split the year into the off-season, early pre-season, late pre-season, and in-season. To start off we need to develop foundational strength by preparing the joints, ligaments, tendons and connective tissue for more demanding training later. Baseball places uneven stresses on the body, like pitchers throw forcefully with the same arm thousands of times a year. Swinging the bat in the same direction over and over develops muscles on one side of the body more than the other side. Over time, small imbalances can create over-use injuries and the best way to prevent this is with exercises that re-develop the natural balance between left and right. The muscles of the trunk and lower back connect the upper and lower body. They support every twisting, turning, jumping, and lateral movement. They are literally the link through which all movement passes. Here are the parameters for this phase of the baseball strength-training program: Time year: Early pre-season, Duration: 4-8 weeks, Days per Week: 2-3, Sets: 2-3, Reps: 15-20 Once you’ve built a solid well-balanced foundation, the next phase of the baseball strength-training program is develop maximal strength. It serves as a foundation for muscular power and speed. The goal is to spend some time in the pre-season increasing your strength to a peak and then to convert that strength into explosive power just as the competitive season approaches. Here are the parameters for this......

Sexual Response

...Sexual Response Cycle which continues to shape the way in which we view sexual functioning, even today. The sequence of phases in Masters and Johnson's model of sexual response is: Excitement phase: Physiological arousal increases quickly. Muscle tension, heart rate, blood pressure, and breathing rate increase. In men, the penis gets erect and the testes swell. In women, the clitoris hardens and swells, the vaginal lips open, and the vagina lubricates. Plateau phase: Physiological arousal continues. In women, the clitoris retracts under the clitoral hood. Men may secrete a small amount of fluid from the penis. Orgasm phase: Physiological arousal peaks. Men ejaculate seminal fluid. Both men and women experience muscular contractions in the pelvic area, along with a sensation of pleasure. Resolution phase: Physiological responses return to normal levels. Men then go through a refractory period that can vary in length, during which they are not responsive to stimulation. The refractory period tends to get longer as men age. Some sex scholars have suggested that an important flaw in the Masters and Johnson research on human sexual response is their inclusion of only orgasmic subjects in their sample. Masters and Johnson studied a biased sample of people. The sample included only people who were both willing and able to perform sexual acts in a laboratory setting. Masters and Johnson didn’t pay attention to individual differences. In reality, people’s sexual responses vary......

...Critical Response Essay Utilitarian Approach: Fred is faced with a difficult decision because he must decide what is more important to him. Is keeping my job more important than contributing to something I don’t agree with? That is the crucial question he must answer. Is that would allow him to keep his job and persuade Greyarea to manufacture less toxic cigarettes. According to the consequentialist theory of Utilitarianism, if he wore to abide by this theory, Fred would respectfully resign from this job. Under principle of utility, the right action is the one that produces the greatest balance of pleasure over pain, or happiness over unhappiness, for everyone affected by that action. He believes that his contribution to the companies harmful products isn’t for him, because the consequences are far more important than maintaining his current job. This is something a consequentialist believes in and respects. Fred would rather spend more time searching for jobs and struggle to provide for his family, than work for a company who profits at the expense of consumers. Fred knows if he were to release the information about toxic additives in Greyarea’s new cigarettes, he would be terminated and presented a lawsuit. But, being consequentialist, he believes his actions are for the greater good and it outweighs the consequences he would receive upon forfeiting such information. As a utilitarian, its in his power to step away from Greyarea and Deontologist Approach: If......

...have several experiences of nice classes. The professors still give lectures but weave group discussions, presentations and films watching into the course schedule; consequently, the stuffs enrich the classes and make them absorbing and interesting. When the instructors lecture, we listen carefully and take notes about the teachers’ summaries, explanations, and comments of articles and essays. As for presentations, we have to report in team works so we look for and collect information collaboratively. After presenting, we could get the sense of achievement. When it comes to watching movies related to what we learn, the films give us profound impressions and new viewpoints varied form previous thoughts. In these ways, students are able to response their reflections and instructors can also get feedback. This kind of instruction is a little bit difficult to practice but seemingly better for students and professors. David Daniels has pointed out the defects of lecture system which has passed down and rooted in the education system. Nonetheless, whether it is proper or inappropriate depends on how professors instruct. What’s more, no matter students, instructors, faculty, or administrators, they are supposed to try to find the balance between lectures and small discussion classes. As a result, both lectures and discussions have advantages and shortcomings; whether they work effectively depends on how people make use of them....

...In response to the reading I found myself open minded to the stereotypical episodes of what a black man goes through. Personally, I found it difficult to relate to because I’m not black or a big man. I can however, imagine through the words of the author what he was feeling as well as what others (victims) were feeling. Then I somehow, found myself recalling times that I too had displayed worry when coming down a dark street, at a club, or even in an empty train cart that would have me alone with a big man, on the other end of it and me feeling like the echoes of the rails would keep me distracted from my fears of something bad happening. For example I can recall a time when I was mugged while walking down my own street. It was during the summer and it was 11pm. I rarely walk the streets at night but this was an exception. My mother’s flight got in last and she was hungry. I decided to walk to the pizza shop at the corner of my street and as I walked down my street I had noticed two men; one black and one white turn the corner together but split up when they saw me. I knew something was going to happen. Sure enough one of them ran towards my purse. WE both spun around and dropped to the sidewalk. As you can imagine I had a strong grip on my purse and the purse itself was made of camel skin. Another time I can recall minding my business waiting for my train in Chinatown and a black man decided to expose himself to me repeatedly until my train......

...I am writing the following in response to Ms Hoa's request to write comments for Language Skills 4A. First, the Language skills subject is an excellent course to take. It is very informative. And it has provided me with the foundation that I will need to make further advancement in Foreign Language coursework. The instructor, Ms Hoa, works very hard in class to get his ideas across to the students. I really enjoy the way she uses her voice to command students' attention. Ms Hoa is very thorough in lecturing. However, you already knew that we have to practice writing, reading, grammar. I think the pace of this course is hard and fast. the students can not manage their time effectively in order to receive quality materials day-in, day-out. I was reminded of the old adage, "Practice makes perfect”, Those exercise assignments took hours and hours to complete! But we do not have time enough. The pressure on time made it difficult be prepared. I was still surprised at the intensive pressure, especially when the final examination of the semester was approaching. Personally, we should separate 4A and 4B into: Listening and Speaking, Grammar and Writing, and Reading and Vocabulary. And I would like to have seen more real practice given in the lectures. For me, this helps to crystallize the definites, grammars by placing them in context. Finally, the book which we used is too old, we need to choose other materials. I'm sorry if this is offensive, but that's the way I feel. I...

Regulation of Physiological Systems by Nutrients

...REGULATION OF PHYSIOLOGICAL SYSTEMS BY NUTRIENTS Free Radicals, Antioxidants, and Nutrition Yun-Zhong Fang, Sheng Yang, and Guoyao Wu, PhD From the Department of Biochemistry and Molecular Biology, Beijing Institute of Radiation Medicine, Beijing, China; the Division of Animal Nutrition, Department of Animal Science, China Agricultural University, Beijing, China; and the Department of Animal Science and Faculty of Nutrition, Texas A&M University, College Station, Texas, USA Radiation hazards in outer space present an enormous challenge for the biological safety of astronauts. A deleterious effect of radiation is the production of reactive oxygen species, which result in damage to biomolecules (e.g., lipid, protein, amino acids, and DNA). Understanding free radical biology is necessary for designing an optimal nutritional countermeasure against space radiation–induced cytotoxicity. Free radicals (e.g., superoxide, nitric oxide, and hydroxyl radicals) and other reactive species (e.g., hydrogen peroxide, peroxynitrite, and hypochlorous acid) are produced in the body, primarily as a result of aerobic metabolism. Antioxidants (e.g., glutathione, arginine, citrulline, taurine, creatine, selenium, zinc, vitamin E, vitamin C, vitamin A, and tea polyphenols) and antioxidant enzymes (e.g., superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidases) exert synergistic actions in scavenging free radicals. There has been growing evidence over the past three......

Physiological Disorders

...Physiological Disorders Nature and diagnosis of physiological Disorders In this assignment I am going to be creating a workbook for level 3 students who study health and social care course which can help them with their studies and support I will be talking about two types of disorders which are Diabetes Mellitus Type 2 and Cerebral Vascular Accident (CVA). P1 Explain the nature of two named physiological disorders. The two types of physiological disorders I am going to be talking about are Diabetes Mellitus Type 2 and Cerebral Vascular Accident (CVA). I’m going to start by naming the physiological disorder with a definition for the both. Diabetes Mellitus Type 2: This type of physiological disorder is the most common form of diabetes. If an individual was to have this type of disorder the body wouldn’t be using insulin properly. This is called insulin resistance, because at first the pancreas would have made extra insulin which would have made up for it. Type 2 diabetes was once known as adult onset or noninsulin dependent Diabetes, this is a very chronic condition for an individual to go through. So anyone having this physiological disorder will have conditions which will affect their body metabolizes sugar. Glucose is very significant source of energy which your body need. If you have type 2 diabetes your body will either resists the effects of insulin this is a hormone which’s help regulate the movements of the sugars which go into your cells, or it doesn’t......

...A TWO-PAGE RESPONSE TO CONRAD’S HEART OF DARKNESS This paper seeks to give a response to Conrad’s Heart of Darkness. Heart of Darkness centers on Marlow and his journey up on the Congo River to meet Kurtz, a civilizer. His quest reveals dehumanizing effects of colonialism and brutalities meted upon the people of Congo by the company’s agents and, he finally learns the truth about Kurtz, a universal genius. Colonialism, imperialism, savagery verses civilization, and racism are the most common issues explored in the book. My major appreciation of the novel lies in how Conrad presents the theme – the horrors associated with imperialism. His concrete descriptions paint various pictures that make it so real for readers to imagine and feel the pain and trauma of the natives of Congo during the era of colonialism. Imperialism is defined as the policy of forcefully extending a nation’s authority by the establishment of economic and political dominance (The Chambers Dictionary). Some textual evidence of the theme, horrors associated with imperialism, are presented below: Forthwith, the natives were made slaves by their colonial masters and were treated as savages. Marlow confirms this, ‘A slight clinking behind me made me turn my head…and all were connected together with a chain whose bights swung between them rhythmically clinking’ (p. 10). Another instance is revealed in the text by Marlow. He becomes the eye of narration for Conrad, and this process further adds to the many......

Physiological Measurements

...Danielle Fuller Unit 335 CA Physiological measurements OUTCOME 1: Describe current legislation, national guidelines, organisational policies and protocols affecting work practice. When taking physiological measurements you have to take into account of the standard precautions. Bullet pointed below are some of the legalisations that relate to taking physiological measurements. Confidentiality * It is important to think about confidentiality when taking a patients physiological measurements because by law patients notes and details have to be kept private. Health & Safety Act 1974 * It is important to have knowledge of the health & safety at work act 1974, because this outlines your responsibilities as an employee, some of these include, correct use of work items provided by your employer, for example physiological measurement tools. Consent * Consents is a patient’s voluntary agreement for a health care worker to provide care. It is extremely important to have a patients consent before taking physiological measurements because a competent adult has a right under common law to grant or withhold consent. OUTCOME 2: Explain the principles of blood pressure to include: • blood pressure maintenance • differentiation between systolic and diastolic blood pressure • normal limits of blood pressure • conditions of high or low blood pressure What is a blood pressure? Blood pressure is measured in millimetres of mercury (mmHg). The reading of a blood......
