Module 1 Health Status and Benefits of Physical Activity Lesson 2 Current Health Status The typical American lifestyle does very little to provide the human body what it needs to maintain proper health. From the mid 1980’s to the present, the wealth of technology and automation in the US has begun to take a toll on public health. Advances in technology have essentially eliminated the need for physical exertion in a daily life. This lack of daily movement is a major influence on American’s ever expanding waistlines as well as chronic diseases. Leads to obesity and chronic disease Leading causes of death greater than 57% cardiovascular and cancer. More than 80% could have been prevented by a healthy lifestyle program Cardiovascular disease is a broad term used to describe a range of diseases that affect the heart of blood vessels. More than 35% of all deaths in the US attributed to cardio vascular disease (high blood pressure coronary heart disease, cognitive heart disease, and stroke) CHD: arteries of the heart are narrowed by fatty deposits such as cholesterol and triglycerides preventing the heart from receiving oxygen and nutrients. Cost of CV disease in the US was estimated at $393 billion in 2005 Improving cardiorespiratory endurance through daily physical activity and a regular aerobic exercise program helps to control and improve most risk factors associated with CV disease. According to research, moderate to vigorous physical activity program can be as important as quitting smoking, managing blood pressure or controlling cholesterol for previously inactive adults. Even though aerobically fit individuals have a lower incidence of CV disease, aerobic exercise cannot erase a lifetime of unhealthy lifestyle habits such as smoking and a high fat diet. Overall management of risk factors is the best solution for managing CV disease. Cancer is the second leading cause of death in the US, behind cardiovascular disease. It has been estimated that men have a 44% probability and women have a 38% probability of developing cancer during their lifetime Lung cancer: 87% accounted for because of lung cancer, 30% of all cancer deaths, 1/3 of all cancer deaths are related to unhealthy nutrition, sedentary

lifestyle, and excessive body fat. Because of better detection and treatment strategies, those living with cancer have increased substantially. However, the most effective way to prevent cancer is to incorporate healthy lifestyle habits such as proper diet, exercise and smoke cessation. An active lifestyle has been shown to deter cancer. Physical fitness and cancer have an inverse relationship. Regular exercise can reduce the risk of cancer by 20-30 percents as well as colon and uterine. Moderate exercise improves the autoimmune system, which also plays a role in the prevention of cancer Obesity: One contributing factor to CV disease and cancer is obesity. Obesity is the condition of being considerably overweight, and refers to a person with a BMI of 30 or greater, or ,who is at least 30 pounds over the recommended weight
