...Aerobic and Anaerobic Exercise You have probably heard the terms "aerobic" and "anaerobic" before, but do you actually understand what the differences are between these two forms of exercise? It's likely you can name some exercises which fall into each category such as walking for aerobic exercise and strength training for anaerobic exercise, but do you know why these things fall into those respective categories. Let's take a closer look at the differences between these two forms of exercise and explore what is best for your body. Oxygen Supply The technical difference between aerobic and anaerobic exercises is the amount of oxygen required by the muscles for support and where that oxygen is coming from. With aerobic exercise your muscles need a continued supply of oxygen, which comes from the lungs. Throughout the workout your muscle activity depletes its store of oxygen so it must be replaced through the lungs, which is why you typically breathe heavy while out for a jog or walk. With anaerobic exercises the lungs don't have time to supply oxygen and the exercises are performed without that replenishing supply. Since the lungs are not working hard to replenish oxygen to your muscles, you typically don't get as out of breath with these exercises. Length of Exercise Session Aerobic exercises generally last a longer period of time than anaerobic exercises. Consider the difference between a power walker who goes out for 30-90 minute walks and a weightlifter that does......

...The company I pick from S&P 500 is Google Inc., which is a multinational corporation specializing in internet-related service and products. Google has been estimated to be a rapidly growing global technology leader focused on improving the way people connect with information, and its trading stock price is remained really high and still on the rise. The expected sales are given by Capital IQ from year 2014 to year 2018, and their values are listed below in the table. By calculating the average growth rate of sales over next five years, which is 12.8%, and have it compared with the one from the previous three years, which is 25.8%, it can be concluded that the projected sales value given by Capital IQ are reasonable. The average growth rate for the next five years represents a stable rate for a longer term, which should be lower than the short-term one when seeing the future performance of the company in a long-run view (Appendix A). Table1. Expected Cash Flows (in millions) | 2014 | 2015 | 2016 | 2017 | 2018 | Sales | 68,176 | 78,377 | 88,614 | 98,769 | 109,330 | The estimated EBITDA to Sales ratio is gained by calculating the average value of EBITDA margins from year 2011 to year 2013, which is 33.3%. Because the sales margins are acquired by Capital IQ from the market data as reliable source, we can use the average of the previous three years’ EBITDA margins as a constant multiple to project the future five years’ EBITDA. By assuming a constant......

...workouts for this class, I started seeing a dramatic change in my power of not getting tired quickly, of taking a longer time to get exhausted and shedding pounds with the pace of time. I do believe that one should have a moderate physical activity included in their daily lifestyle because it helps boost our strengths and makes us competitive towards our goals. As the book Principles and Labs for Physical Fitness mentions, “Regular moderate physical activity provides substantial benefits in health and well-being for the vast majority of people who are not physically active (Hoeger, 6)”. It was a tough routine to follow required by the class because of time conflicts and utter laziness but in order to fulfill the requirements, I started working out which included the warm up exercises, abdominal crunches, and stretching. It wasn’t long before when my muscles started getting sore and I felt I could barely move. This was because I did not follow the basic guidelines. The author mentions in the book Principles and Labs for Physical Fitness that “Mild stretching before and adequate stretching after exercise help to prevent soreness and stiffness (Hoeger 329)”. Although I did stretching before and after, but it wasn’t as much as required which lead me to have muscle soreness. As this class ends, I have understood that stretching is highly important while exercising as it helps avoid the latter problems. The most important aspect of working out, and following a daily routine......

Ways to exercise is by walking, going up and down stairs and even stretch to help strengthen muscles and bones. It’s very important that children who are obese exercise daily because it is a high risk that they will be obese for their entire live. Eating healthy and cutting down on portion will also help prevent obesity. Obesity effects children on many different levels to where emotional stress takes place. Some children may get teased on in school which causes children to eat more and do less physical activities. For adults they also experience emotional stress because of problems they may be going through such......

...LABORATORY EXERCISE #1 Carbon Dioxide Emissions from Automobiles   The reason we focus on CO2 is that emission of this gas changes the climate.  Natural emission of CO2 is much greater than that produced by humans.  The natural carbon cycle in nature absorbs much of the CO2 produced.  However, vegetation and oceans only absorb about 40% of CO2 produced.  In addition, human activities such as livestock production add significantly to the production of both CO2 and methane.  So what are some of the numbers?   CO2 released by consumption of vegetation by animals and microbes – 220 gigatonnes of CO2/year CO2 released by respiration of vegetation – another 220 gigatonnes of CO2/year CO2 released by the oceans – 332 gigatonnes of CO2/year CO2 released by human activities – 29 gigatonnes of CO2/year   Offset – the absorption of CO2 by plants (450 gigatonnes/year) and the oceans (338 gigatonnes/year) for a total of 788 gigatonnes/year.  What this tells us is that vegetation produces about 440 gigatonnes and absorbs about 450 gigatonnes.  The oceans produce 332 gigatonnes and absorb 338 gigatonnes.  Considering variations from year to year, this produces a rough balance.  Adding 17.5 gigatonnes/year through human activities is the real concern because this is not absorbed by natural processes and we have to consider the cumulative effect.        We hear a lot about carbon dioxide emissions from everyday activities.  Where does all this CO2 come from?  It all starts with......

...Evaluate the importance of regular exercise in maintaining a healthy body and mind; to what extent should the state play a role in ensuring that its citizens exercise regularly? Refer to at least two countries in your answer. Abstract Recent years have witnessed a dramatic increase in physical activity and fitness around the world. This essay will focus on the benefits of exercise for both physical and mental health. It is obvious that exercise helps people prevent a variety of diseases such as diabetes, cardiovascular, depression and Parkinson’s. This also raises an argument on whether government should play an important role in promoting physical activity.

...EXSC 101: CAREER OUTLOOK 2 Abstract The overall job of a personal trainer is to teach others how to exercise in a proper and effective manner. However, there is much more to personal trainers than just teaching people how to exercise properly. A personal trainer will not only be a trainer but a friend, coach, and motivator as well. The job outlook for fitness trainers is excellent. This occupation is projected to grow faster than the average for all occupations through 2020 (McKay, 2014). Personal trainers earned a median annual salary of $31,030 and median hourly wages of $14.92 in 2011 (McKay, 2014). The salary and hourly wage of a personal trainer varies greatly based on experience, their employer, location, what type of contract they are on, etc. I would like to be a self-employed personal trainer who rents space at a fitness center or gym. Therefore, my total income will depend on the success of my own business. The working conditions of a personal trainer can be busy and demanding. Personal trainers usually work in shifts: varying from very early mornings, evenings, and weekends. Depending on what type of physical trainer the individual is they will either work in gyms, recreation centers, or even their own home. Opportunities are expected to be good for fitness workers because of rapid growth in the fitness industry. Many job openings will also stem from the need to replace the large numbers of workers who leave these occupations each year (Delta,......

...Exercise When a person is asked about the physical aspects of his body or even his health, one statement that person will never say is that he is perfect. No matter who is asked or what their situation everyone has something about their body that they would like to improve on, and without a doubt people with health problems would like to improve on their overall health. Individuals who are involved with regular physical activity are proven to have better fitness and better overall health when compared to those who are not involved in physical activity. There are many aspects of a persons life that can be improved. Whether it be better health or better fitness, regular exercise can dramatically change a persons life. In many studies, for a variety of different reasons, it has been proven that overall wellness and happiness begins with the brain. The way a person feels and the confidence they have can affect a persons way of life and over time the persons health. When comparing individuals who involve themselves in regular exercise to individuals who do not, people who exercise regularly are proven to be more happy. Regular exercise increases the production of serotonin produced by the brain. This causes a person to be in a better mood and to have more confidence in their daily life. Without regular exercise a person will have lower levels of serotonin causing bad moods and less self confidence. Low levels of self confidence can be very dangerous and can lead to......

...Types of exercise Physical exercises are generally grouped into three types,[7] depending on the overall effect they have on the human body: Flexibility exercises, such as stretching, improve the range of motion of muscles and joints.[8] Aerobic exercises, such as cycling, swimming, walking, skipping rope, rowing, running, hiking or playing tennis, focus on increasing cardiovascular endurance.[9] Anaerobic exercises, such as weight training, functional training, eccentric training or sprinting and high-intensity interval training, increase short-term muscle strength.[10] Categories of physical exercise Strength training Agility training Eccentric training Resistance training Interval training Continuous training Sometimes the terms 'dynamic' and 'static' are used. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly (during the exercise). Categories Physical exercise is used to improve physical skills. Physical skills fall into the following general categories: Cardiovascular/respiratory endurance, Stamina, Strength, Flexibility, Power, Speed, Coordination, Agility, Balance, and Accuracy.[11] Metabolic equivalent of task The Compendium of Physical Activities was developed for use in epidemiologic studies to standardize the......
