Health Benefits of Exercise
Physical exercise has long been regarded as a positive thing for the human
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).
There are many reasons why the American Heart Association recommends at least 150 minutes of physical activity per week (3). Exercise has many proven benefits for the human body including physiological, mental and preventative aspects. Usually, one of the main ideas behind exercise is weight loss or healthy weight maintenance and this is crucial in preventing or regressing many diseases. Obesity is quickly becoming a global epidemic, and in the United States alone over the last two decades there have be...

...cise has also been proven to cause a release of a handful of other neurotransmitters and hormones with similar affects like seratonin, dopamine, epinephrine and adrenalin (12).
It is a well known fact that obesity is a leading cause of many diseases worldwide. Maintaing a healthy lifestyle can not only prevent obesity, thus avoiding these diseases - it can also cause disease to regress if stored adipose tissue is lost. Evidence supports that the physical act of exercise has a positive effect on our metal and physical well being through many different pathways and some are more clear than others. However, decreasing the world’s population of obese individuals would in turn lessen the number of people suffering from a plethora of preventable diseases and ailments. We just have to remember that if we burn what we eat we are on the pathway to a long and healthy life.

Exercise is an easy and attainable way to lose weight. A study in Durham, North Carolina showed this. Overweight men and women aging from 40-65 were split into three groups. Group 1 had to do the equivalent of 20 miles of jogging per week at 65%-80% peak oxygen consumption. Group 2 had to do the equivalent of 12 miles of jogging per week at 65%-80% peak oxygen consumption. Group 3 had to do the equivalent of 12 miles of jogging per week at 40%-55% peak oxygen consumption. Of 302 subjects screened, 182 met criteria and were randomized and 120 completed the study. There was a significant (P<.05) dose-response relationship between amount of exercise and amount of weight loss and fat mass loss. The high-amount/vigorous-intensity group lost significantly more body mass (in mean [SD] kilograms) and fat mass (in mean [SD] kilograms) (-2.9 [2.8] and -4.8 [3.0], respectively) than the low-amount/moderate-intensity group (-0.9 [1.8] and -2.0 [2.6], respectively), the low-amount/vigorous-intensity group (-0.6 [2.0] and -2.5 [3.4], respectively), and the controls (+1.0 [2.1] and +0.4 [3.0], respectively). Both low-amount groups had significantly greater improvements than controls but were not different from each other. Compared with controls, all exercise groups significantly decreased abdominal, minimal waist, and hip circumference measurements (http://www.ncbi.nlm.nih.gov/pubmed/14718319).
Due to the strong and growing evidence in scientific literature on the beneficial effects of physical activity on health and well-being, the importance of Clinical Exercise Science has increased. Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. Exercise, is a subcategory of physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components of physical fitness is the objective (http://www.who.int/dietphysicalactivity/pa/en/; last accessed on 30 April 2016). Generally speaking, Clinical Exercise Science is an applied clinical branch which deals with the application of various exercise modalities for
Millions of Americans and people worldwide are overweight or obese. Obesity develops when “calories consumed exceeds calories expended” (“Obesity and Genetics”). “Obesity rates have more than doubled in adults and children since the 1970’s,” and in the present day it is estimated that “two – thirds of U.S. adults are overweight or obese” (Ogden). Being overweight or obese highly increases the risk of deadly health problems, therefore this statistic states that the majority of the United States population is at risk of obtaining life–threatening diseases. Around forty years ago obesity would not effect this abundant number of people; however today’s society consumes more fast food in addition to spending most of their hours doing sedentary activities (Green). There are now many causes of obesity such as environment, genetics, bad habits, culture and economic level. Obesity has many negative impacts on the human body. It can very likely cause diabetes, joint pain, sleeping problems, depression, and many hazardous diseases (“Explore Overweight”). In contrast to this, there are some possible solutions to obesity such as physical activity, dieting, and surgery. Obesity is a widespread epidemic that unfavorably affects the body, but with exercise fused with dieting the disease could be kept to a minimum.
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).
Staying healthy does not only mean to eat a healthy diet, but also to be active and to provide our body with stamina so it can fight various diseases. According to Myers (2003) around a quarter of a million deaths in the United States are caused by insufficient physical activity. The US Public Health Service (1996) has provided enough evidence towards the effect of physical exercise on cardiovascular (e.g. coronary heart disease) and non-cardiovascular health (hypertension, osteoporosis, colon cancer etc.). They followed a group of people for several years and found a positive correlation between the amount of participants’ physical activity and their health problems. So how much exercise is just enou...
All over the world, it is believed that physical exercises help people achieve wellness. Physical exercise not only encourages physical wellness but also have a significant impact on mental stability and health. Although such positive believes stand, many benefits of physical activity has lost value overtime, as people nowadays have the tendency to rely on modern technologies and machineries, which are believe to make life easier. This often leads to shortage of physical activity and over sometime both physical and mental health will deteriorate. This argumentative essay, will explain how engaging in physical exercises improve one’s mental health.

Thirty minutes of exercise a day may be the trick to keeping bad health away! Cardiovascular exercise strengthens all of the body’s muscles. Well known muscles, such as the ones in the arms and legs are toned and seen as exterior health. Meanwhile, the body’s inner muscles and organs, the heart and lungs in particular, are toughened for optimal inner health. Cardio exercise benefits numerous body systems including, muscular, cardiovascular, and respiratory.
