  3. Hypokinetic Conditions • Cardiovascular disease • Cancer • Back problems • Obesity • Diabetes • Osteoporosis • Mental health

  4. Lab 6ainformation Cardiovascular Disease • Coronary heart disease (CHD) • #1 cause of death • Stroke • #3 cause of death According to the American Heart Association, approximately 42% of the population will die from a form of cardiovascular disease

  5. Modifiable Risk Factors for Coronary Heart Disease • Smoking • Hypertension • Hypercholesterolemia • Physical Inactivity • Overweight / Overfat American Heart Association

  6. Activity and the Heart • Clean vessels • Good collateral circulation AHA: Activity and the Heart

  7. Activity and Atherosclerosis • Exercise reduces lipids • Exercise increases HDL cholesterol(the “good” cholesterol) • Exercise reduces fibrin deposits

  8. Activity Reduces Coronary Heart Disease Risk CHDRISK Level of Physical Activity

  9. Cancer • Second leading cause of death • Various types of cancer • Causes still largely unknown

  10. Activity Reduces the Risk of Some Cancers • Reduced transit time • decreased risk of colo-rectal cancer • Reduced levels of hormones • decreased risk of breast cancer and some reproductive cancers • Improved immune system • Reduced levels of body fat

  11. Back Problems • 80% of the population will experience back pain at some point in their life • Back problems are a major cause of inactivity in adults

  12. Activity Reduces Risk of Back Pain • Improves flexibility of joints and ligaments • Improves musculoskeletal strength and endurance

  13. Obesity • Approximately a third of the population is overweight • Obesity increases the risk of many other diseases

  14. Activity Promotes Weight Control • Burns calories • Increases rate of metabolism • Promotes fat loss and preserves muscle

  15. Diabetes Mellitus (DM) • Type I (juvenile onset) • Pancreas fails to produce insulin • Type 2 (adult onset) • Lack of sensitivity to insulin • Often caused by obesity

  16. Activity Reduces Risks of Diabetes • Type 1 • Reduces disease risk • Increases quality of life • Type 2 • Decreased insulin requirement • Reduced fatness

  17. Osteoporosis • Progressive loss of bone mineral density • Occurs commonly in old age • Occurs at an earlier age and more frequently in women than men

  18. Causes of Osteoporosis • Loss of sex hormones • Low calcium levels • Physical inactivity • High protein intake • Smoking • Caffeine

  19. Activity Reduces Risk of Osteoporosis • Increases peak bone mass • Slows decline in bone mass

  20. Exercise Improves Mental Health • Reduced depression • Reduced anxiety • Increased self-esteem

  21. Click for info on compression of morbidity Activity Slows the Aging Process • Time dependent aging • Acquired aging (related to lifestyle)

  22. Activity also Improves the Quality of Life!

  23. Exercisers Are: • 50 % more likely to quit smoking • 40 % more likely to eat less red meat • 30 % more likely to cut down on caffeine • 250 % are likely to eat low calorie foods and drinks • 25 % more likely to cut down on salt and sugar than non- exercisers

  24. Exercisers Tend To Have: • More positive feelings about their health • More positive feelings about their careers • More aware of stress and adaptation to stressors

  25. Increase of Health Risk • Studies have shown that addictive health-risk behaviors have increased in the United States • 4 million children have above normal blood pressure • 27 million children have higher than desirable serum cholesterol

  26. At least one third of children are obese • 3,000 children become smokers every day

  27. Results of 1993 Survey • 4,000 Jefferson County students were surveyed • 82 % of 8th and 10th graders reported having used alcohol • 29 % of 10th graders reported that they have engaged in binge drinking

  28. 36 % of the total group reported using an illicit drug • 37 % reported watching three or more hours of TV on an average school day

  29. Conclusion • “Children who improved their physical performance and health, through training, were able to accomplish more in all areas of their lives after training than they could before.”
