The word 'fitness' is very vague as fitness is built up of many
factors. The main ones include, general Fitness, aerobic fitness and
specific fitness.
General fitness is the ability to meet the demands of every day life.
General fitness is closely liked with health related fitness and it
has several components including Strength the force muscles exert when
they contact. Flexibility or suppleness, the range of movement at a
joint. Speed, is the ability to move your body or a section of your
body quickly. Body composition, the percentage of fat and lean tissue
in your body. If you have too much fat, or too little fat, you are
seen as being unfit. Stamina, is the body's ability to keep going for
long periods without tiring. It is a combination of muscular and
cardiovascular endurance. Cardiovascular endurance is the ability of
the circulatory system to deliver the oxygen muscles need (also known
as aerobic fitness). Muscular endurance, is the ability of muscles
repeating contractions without tiring

Obesity has affected the world in many ways: task forces have been formed to address the issue, people are suffering from health problems due to obesity, and others suffer from psychological and social issues. Nearly two-thirds of the United States population is overweight. There are several ways to determine if a person is obese or overweight. Experts say that a person’s body mass index is the best way to determine an adult’s weight in relation to their height. A BMI of 18.5 to 24.9 kg/m2 is considered normal, adults with a BMI of 25 to 29.9 kg/m2 are considered overweight.
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).
defined as an excess of Body Fat (BF). There is no consensus on a cutoff point for excess fatness
Webster’s dictionary defines obesity as an increase in body weight due to excessive accumulation of body fat. It is a condition or disease in which “the natural energy reserve of humans or mammals, which is stored in fat tissue, is expanded far beyond usual levels to the point where it impairs health.” Obesity is most often measured by using the BMI (body mass index), which is calculated by dividing the weight in kilograms by the height squared in meters. A desirable BMI for children to sustain a healthy life is between 18.5 and 25. A child with a BMI over 25.0 kg/m 2 is considered overweight, while a BMI over 30.0kg/m 2 is considered obese, and a BMI over 40 is morbid obesity.
Obesity is when a person’s calorie intake exceeds one’s activity level. Activity burns calories and what ever calories are not burned, are stored as fat cells in the body. 19-24% is a healthy body mass index (BMI) for an individual. Mary Jo Thomas, M.D., states that “One that is obese has a body mass index of over 30. With a BMI of 30 or greater, one is at an immediate health threat.” (Thomas, 2013) Scientific evidence supports that the main causes of an obesity may include: ““increasingly sedentary lifestyle; high consumption of simple carbohydrates and fats (especially the refined sugars and greasy preparations common in junk and fast foods); and stress. To a lesser degree illnesses such as hypothyroidism (u...
According to the CDC, Centers for Disease Control and Prevention, adults should do at least 150 minutes a week of moderate-intensity exercise, or 75 minutes week of intense aerobic activity. Everyone should try to do at least the recommended amount of weekly exercise. Not exercising can be detrimental to one’s health. Exercising moderately for at least 150 minutes a week or working out intensely for 75 minutes can add, on average, 3.4 years to one’s lifespan, while people who do not exercise have the highest premature death rate. Being active has both mental and physical benefits, adding exercise to your routine can create a happier, healthier lifestyle. Exercise, no matter how strenuous or simple, is an important activity for all people.
Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).
It is common knowledge that exercise is one of the best ways to stay healthy. Regular exercise has many effects that benefit the human body. But how much exercise is needed to see improvements? The Center for Disease Control states, that according to the 2008 Physical Activity Guidelines for Americans, two types of physical activity are needed to improve your health- aerobic and muscle-strengthening. The CDC recommends 150 minutes a week of moderately intense aerobic activity, like brisk walking, or 75 minutes a week of vigorously intense aerobic activity, like jogging or running along with two days a week spent doing muscle strengthening activity on the major muscle groups. Consistently following this recommended
Body composition is one of the five health related fitness components and it is the percent body fat, bone, water and muscle found in your body. Although fat is associated with negative connotations, it has important functions in our body such as the cushioning of organs, shock absorption and temperature regulations. This ‘positive’ fat is known as essential fat, and the ‘negative’ fat is known as nonessential fat. The percent body fat is used to determine the total fat found in your body and it is based on gender and size of each individual. In the textbook “Concepts of Physical Fitness: Active Lifestyle for Wellness” by Corbin, he states that fat location influences health risk; based on where the fat is located you could be considered an apple or a pear. A person considered an apple has fat in the upper body. This is often found in men and in menopausal women. A pear shape, which is most common in women than men, has more fat located in the hips and upper legs. Corbin defines visceral fat as fat located at the core of the body (abdominal cavity), and subcutaneous fat as fat located under the skin.
An unavoidable part of life is dealing with stress and learning how to handle it. While the busyness of people’s lives steadily increases, the stress level of an individual tends to rise. There are many stress relief methods that exist. I believe cardiovascular exercise is one good beneficial approach to reducing stress. Different forms of cardio exercise can physically contribute to ease stress. It can also provide benefits for the mind. Since exercise is an outlet for frustration, it can be a healthy and effective way to release these negative emotions. There are many practical things that someone could do to exercise to relieve stress. By prioritizing cardiovascular
Want to feel better, have more energy and reduce your risk of serious disease? Look no further than exercise. The health benefits of regular exercise and physical activity are hard to ignore. Physical activity not only makes a person feel better, it can actually increase a person’s life span. Many people battle obesity and side effects that are caused by this sickness. The American Medical Association has recognized it as a disease as of two thousand and thirteen. The Liberal government has just released a document that they are cutting the Children 's Fitness Tax Credit. This is a political mistake since physical activity is the key to a healthy life and a life free of disease.
Over the past century we have become increasingly sedentary due to the technical advancements of today's world. Ironically, while machines and improvements in transportation and communication have made our lives easier, studies show that the decline in our physical activity associated with these advancements plays a large role in the decline of our health.
The benefit of physical fitness is to prevent obesity and encourage a healthy lifestyle thru training and focusing on the body’s compositions. Physical fitness is the measure of the body’s ability to go full capacity. If one doesn’t exercise ones body doesn’t work at its full potential all the time. Exercise can lower the risk of having major problems with ones body and relieve stress.
Cardiovascular disease is known to be the leading cause of death. One would ponder upon the main cause of such a disease. When it comes to the risk factors, the two main causes of cardiovascular disease are lack of physical activity and unhealthy eating habits. “You are what you eat” is a common phrase, which is used to emphasize the significance of a healthy diet as key to a better health. For instance, if an individual consumes unhealthy meals on a daily basis, he or she would accumulate fat in their body and be unhealthy. Exercising and consuming healthy foods daily not only improve the health of an individual, but also extend his or her life span. The main benefits of exercising and nutrition include weight control, increased energy, better health, better mood, and stronger bones.
