The American Heart Association: How Exercise Affects The Body

Exercise: The American Heart Association (AHA, 2014) recommends exercising at least 30 minutes of moderate-intensity aerobic activity at least 5 days per week for a total of 150

Expending on the PAG, Healthy People 2020 estimated, on a national level, over 80 percent of adults and youth are not actively participating in daily physical activity, potentially increasing the risk of developing chronic health related diseases such as; heart disease, diabetes, obesity, or exacerbating current health issues (HHS, Healthy People 2020, 2016).

A person's cardiovascular system is a very important part of fitness and one's overall health. Here are a few of the best exercises; walking running, cycling, rowing, swimming. Research suggests at least 150 minutes per week, a minimum of 30 minutes per day, five times a day a week. A few exercises that are best are, climbing, playing sports, and running is also some of the most common and affordable. At least 25 minutes of vigorous aerobic activity at least or a combination of moderate and aerobic activity are some of the best options to benefit your cardiovascular system.

During rest or normal physical activity muscles use glucose and break it down to CO2 and H2O to give ATPs (energy) to the muscles to work. This reaction requires oxygen which comes from the blood. Therefore your heart constantly requires to pump oxygenated blood from the lungs to the body muscles and carry back the CO2. the independent variable would be exercise, leaving the heart rate as the dependent variable; thus it is the one that it affected. This lab was to fully understand how the heart is affected by exercise.During exercises, more ATPs are required and hence more glucose is broken down, therefore more oxygen is required. therefore the heart needs to pump oxygenated blood into the muscles faster and Therefore the heart rate increases.

The heart needs to be challenged, and for a sustained amount of time. The current standards for exercise to reduce risk of diseases like Cardiovascular Disease are 150 minutes a week of moderate exercise or 75 minutes of intense exercise. The pros list the following exercises as “the best,” but the best is what you enjoy

Over a period of 27 years, the scientists monitored 4,872 young adults aged between 18 and 30, who underwent treadmill exercise testing in the form of two-minute running sessions of increasing difficulty to work their heart and lung capacity. Their findings showed that each additional minute of exercise was linked to a 15% lower risk of dying and a 12% lower risk of cardiovascular disease (Johns Hopkins Medicine,

Physical inactivity is the first cause of heart disease. The recommended exercise per week is 150 minutes, but many do not even do half of that. Often time’s people purchase a membership to a gym so they can exercise; however, the gyms are always empty. The same goes for public parks; most of the time they are always empty or only have a couple of people. It is said that, people with gym memberships stop going after five months, and that most people do not go because laziness takes over the body and mind. In the American society, citizens have become very indolent when it comes to exercising and maintaining their correct weight and proper BMI (Body Mass Index). Physical inactivity develops into heart disease when the heart is not being “worked

Yes, physical inactivity plays a role in the obesity issues, as it's one of the main underlying causes of obesity (another cause is poor dietary and nutrition intake). According to the American Society for Nutrition, physical inactivity can lead to an increased likelihood of obesity by seventy-three percent. Therefore, based on the statistical findings, both could go hand in hand to solving the issue with the external health of the citizens, as both variables can fatally lead to further health complications. Therefore, focusing on these variables provides a better health outlook on the body.

Chapter three of our physical education book referenced our physical wellness and what that means. All areas of this chapter pointed to how we can use physical exercise to decrease our risk of diseases, such as hypokinetic disease. This is a Type II Diabetes that is caused by too little physical activity. This chapter also covered how Cardiovascular disease is the leading cause of death in the Unites States. Adding physical activities helps to reduce this risk and it also strengthen your heart in the process.

When reading this article, it sets out to introduce the crucial role that daily physical activity does for the body and how it relates to gene. At one point in time, physical inactivity and a poor diet was not considered to be a cause of chronic diseases. In today’s times though, the CDC declared that it is an actual cause of chronic disease and is the second leading cause of death in the U.S., at 12.5%. What is startling and well-known, is that many chronic diseases such as type II diabetes, heart disease, and certain cancers can be prevented with exercise, yet so many people don’t.

I. Think of four important people in your life. One of these four people will be diagnosed with heart disease, diabetes, obesity, or depression in the course of their life, which may eventually cause death. Imagine if that person had simply exercised for 30 minutes, 4-5 times a week. They would most likely not be suffering from the disease, and living a happy healthy life.

Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

Merely not using a person’s body is harmful. Not being active results in a person’s muscles becoming weak and out of condition. The effectiveness of a person’s heart and lungs will decrease. A person’s joints will become stiff and can be injured easily. Inactivity can be as much of a health risk as smoking. In addition children have become extremely lazy with all the

Physical Activity is undeniably good for everyone, not only does it keep you fit and healthy but when started at a young age, it can set up good habits for life. Sometimes however, people do not take care of their physical wellbeing, resulting in obesity and other eating disorders which can be detrimental to their health.
