The Basic Overview of Exercise Physiology
Drew Fulks
Texas Tech University Abstract
In this essay, the basics of exercise physiology will give the reader a better sense of what the subject covers, the history, the careers that can be available by majoring in exercise physiology. This essay will also cover the difference between clinical exercise physiology (CEP) and nonclinical exercise physiology (NCEP). In the book Exercise physiology: nutrition, energy, and human performance, it goes over the history of how exercise physiology has evolved over the years. This will give a better understanding of how exercise physiology originated and how it became what it is today. In the book Essentials of exercise physiology, it will discuss what

Modern scientific research on exercise has become top of the list for exercise physiologists whose purpose is to study how exercising affects the body. Over the years, exercise physiology has become the top researched sub-discipline of kinesiology. It is considered to be the foundation for fitness and rehabilitation. Exercise physiology can be used for medical patients or people just trying to live a healthier lifestyle.
What Is Exercise Physiology According to Paul Davis, Exercise Physiology discovers the “short-term biological responses to the stress of physical activity” (Davis 2015). In more basic terms, it is the study of how the body responds to exercise or normal physical activity. It also studies “how the body adapts to repeated bouts of physical activity over time” (Davis 2015). This means that over time, exercise physiologist study how the body will change because of repeated exercises or physical activity. These two definitions generally cover the goals of exercise physiologists when they conduct studies to improve the human physical peak and healthy lifestyles. Physiologists will train their patients knowing the safety and risks of workouts to achieve a healthy overall health by implementing workout programs, specifically programs to increase the strength, flexibility, and endurance of their patient. Usually the experiments are researched in a lab

Galen was considered the “most well-known and influential physician” in the early eras (McArdle 2015). Then in the renaissance period, there was a drastic increase in physiology and medicine due to the plagues that were sweeping through Europe. According to McArdle,
Antoine Laurent Lavoisier conducted the first “exercise physiology experiment” measuring the oxygen used and the heart rate of the patient as they breathed through a small tube (McArdle 2015). In the 1900s more drastic research was given to add to the increased knowledge of exercise physiology. Frederick Gowland Hopkins did a paper on lactic acid in muscles. This showed that physiologists began to look at exercise in the molecular level. Today exercise physiology is still increasing in research and is expected to continually increase every year gaining knowledge on how exercise affects the body
Another weakness in the experimental design was that the reliability of the experiment was very low. As each test subject was only tested against each amount of prior exercise once, the impact of random errors is likely very large, which can be seen by the spread of the data on the graph. Although, this was attempted to be rectified by averaging the results of all four test subjects, it does not improve reliability too much. Conclusion: The results of this investigation indicated that a relationship between the amount of prior exercise and muscle fatigue does exist, however the results are also not conclusive enough to speculate on what the relationship is. This means that the hypothesis “If the amount of time spent performing vigorous exercise prior to the set of repetitions increases, then the physical performance (number of repetitions) will decrease” cannot be supported or rejected due to the inconclusive data.
Exercise science possess many traits that attracted my attention whether it dealt with the different job opportunities or the ability to help an individual. There are two areas of exercise science that one can choose as a possible career path or as a major minoring in something else related to this type of work. One of the areas of study includes exercise physiology which can be defined by “the study of how the body’s structures and functions are changed as a result of acute and chronic bouts of exercise”. Not only does exercise physiology promote a healthy lifestyle, but it is closely connected to human performance, fitness, development/aging, and prevention/rehabilitation from disease or injury. Pursuing a degree in exercise physiology allows an individual in this profession to choose between several careers including physical education, exercise science and athletic training (Fisher, 2). In addition, becoming a chiropractor can be achieved through exercise science.

Sports Medicine is a medical field that specializes with physical fitness, treatment and prevention of injuries related to sports and exercise. It was introduced around the early Greek and Roman era when the first modern Olympic Games took place. The Greek felt they could do something to help heal and prevent injuries that the athletes were receiving. Now in sports medicine, certain injuries can only be assessed and treated by specific physicians. These physicians can include physical therapists, athletic trainers, and strength and conditioning coaches. Although sports physicians are most commonly seen by athletes after they are hurt so they can be treated, there are some physicians that are seen before an injury occurs so that they can learn how to prevent injuries.
In the Renaissance, some aspects of medicine and doctors were still in a Dark Age. Outbreaks of disease were common, doctors were poor, medicine was primitive and many times doctors would kill a patient with a severe treatment for a minor disease! But, there were other sections where medicine and the use of medications improved greatly. This paper is written to illustrate the "light and dark" sides of medicine in the Renaissance.
...l., 1987). In a study in which the participants performed sprint interval training (Bayati, 2011), there was an increase in maximal blood lactate from pre to post training, indicating greater capacity of anaerobic glycolysis. This increase was found coinciding with increased peak power, mean power, and total work . Sharp et al. (1986) reported an increase in blood lactate concentrations and total work performed during a 45-s maximal cycle sprint after eight
body - but what actually constitutes exercise? Exercise can be dissected into two major categories, aerobic exercise and anaerobic exercise. Aerobic exercise is usually a lower intensity, longer endurance form of energy usage that raises the respiratory and pulse rate of the individual. The major physiological classification of this type of exercise is that it accesses the aerobic energy generation process - loosely meaning that your cells need and use more oxygen during this type of exercise (1). Anaerobic exercise is a type of activity that is usually short lived and in high intensity, such as weight lifting or short sprinting. This type of activity does not require your body’s cells to take up increased amounts of oxygen. Anaerobic exertion must use a very fast fuel source like the phosphates creatinine phosphate and adenosine triphosphate as well as anaerobic glycolysis (2). If the individual continues to work past the means of anaerobic exercise, the body will begin to use aerobic pathways for energy production like the citric acid cycle and oxidative phosphorylation, which require much higher quantities of oxygen (1).

Being a healthy person, the torment an individual may be unveiling to as a result of poor health is pacified. To keep the body up tight with no stress, while the body is in action the person needs to keep some Fitness vocabulary. These are Cardio Respiratory Endurance, Muscular Strength, Body Composition, Muscular Endurance, Reaction Time, Coordination and Speed. Cardio Respiratory-Ability of the body’s circulatory, cardiovascular endurance measures the oxygen received while working out. Muscular Strength- Amount of force a muscle can produce with a single effort, for example the achievement of lifting weights. Body Composition-Refers primarily to the distribution of muscle and fat of the body, a normal healthy body configuration has enough muscle tissues with a rate of low fat tissues. Muscular Endurance- the maximum force of a muscle and or group of ...
There are multiple possibilities for future research. In particular, testing to discover what relationship the length of time spent exercising holds with the respiratory rate of a subject. Another possibility could include testing to see if the intensity holds an impact on heart rate. Alternatively, an experiment to test at what length of time the heart reaches target heart rate could be conducted or even further or to test what different types of exercise produce what sorts of heart rate. Most importantly, simply repeating the experiment with many more trials would provide much more information and data, which could possibly lead to more accurate results and conclusions.

Many people know when you exercise for long periods of time; your breathing becomes more shallow and quick. The main human organ system used when exercising is the respiratory system. There are two types of respiration your body can carry out, aerobic, with oxygen, and anaerobic, without. The reason for getting tired from exercise is because when the body runs out of the oxygen it needs, anaerobic respiration takes its place. This respiration has no oxygen which means the body releases less energy and produces lactic acid. Lactic acid is a poisonous waste product that stops muscles contracting and relaxing. In this investigation, I will be finding out whether exercise that has two different types of respiration has a strong affect on the heart and its’ cardiac cycle.
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.
In this paper I will be looking at an article called The Over Training Syndrome, which was written in 1994. I will be comparing the information in the article with the content from the week 6 Qualifying Sports Training lecture. This will be done by directly quoting the article, then the lecture and having a short discussion on the quoted point. The four areas of comparison will be; the definition of overtraining, the cause of overtraining, the effects of over training, and the recovery time from overtraining. The goal of this paper is to discuss the advancement in knowledge over the last twenty years in these four points on overtraining.
