  2. 2. 1-2 Chapter 1: Getting Fit: Why Should You Care?
  3. 3. 1-3 Why should you care about being physically active? • Physical fitness marketing comes from many sources – Food – Clothes – Cosmetics – Healthcare products – Equipment – Weight loss programs
  4. 4. 1-4 Key Terminology • Physical fitness • Wellness • Health-related components • Cardiorespiratory endurance • Muscular strength & endurance • Flexibility • Body Composition • Atherosclerosis • Caloric intake • Caloric expenditure • Speed • Power • Coordination • Balance • Agility • Reaction Time
  5. 5. 1-5 • 24% of adults engage in light to moderate physical activity 5 days a week • 12% are active 7 days a week • 60% are active but fail to reach necessary intensity to improve cardiorespiratory fitness • 25% of adults are sedentary Living activities do not incorporate enough physical activity to maintain adequate levels of fitness
  6. 6. 1-6 Physical activity: –Reduces risk of disease –Helps control weight –Contributes to healthy bones, muscles, and joints –Reduces symptoms of anxiety and depression –Relieves pain associated with arthritis –Associated with fewer hospitalizations, physicians visits, and medications
  7. 7. 1-7 Achievement of a healthy lifestyles requires: –Proper medical care –Eating right –Physical activity –Satisfying work –Healthy play/recreation –Proper amounts of rest and relaxation
  8. 8. 1-8 Exercise & Physical Activity • Exercise: – More intense than what an individual does on a daily basis – Must challenge body’s physiological systems – Results in improved function and efficiency – Varies by each individual’s fitness level and lifestyle Figure 1-1
  9. 9. 1-9 Healthy People 2020 Objectives • Can be utilized to develop programs to improve health • Based on scientific knowledge and assembled through a broad consultation process • 28 focus areas were identified by federal agencies
  10. 10. 1-10 • 10 health indicators were identified • Each indicator is linked to one or more objective and based on their: –Ability to motivate action –Availability of data to measure progress –Importance as public health issues
  11. 11. 1-11 Health Indicators • Physical activity • Overweight and obese • Tobacco use • Substance abuse • Responsible sexual behavior • Mental health • Injury and violence • Environmental quality • Immunization • Access to health care
  12. 12. 1-12 Physical Benefits of Being Physically Active • Changes in civilization have resulted in declines in physical activity • All people must be aware of the: –Requirements for good health –Importance of vigorous physical activity
  13. 13. 1-13 Social Rewards of Being Physically Active • Physical activity: – Creates outlets, companionship, and feelings of belonging – Provides strategies for conflict resolution, acting fairly, and complying with rules – Contributes to development of moral and ethical code for behavior – Provides opportunities for socialization
  14. 14. 1-14 Psychological Benefits of Being Physically Active • Physical activity can: – Enhance motivation – Increase self-perception and esteem – Improve mood states and emotional well- being – Reduce stress and anxiety – Create a realistic body image
  15. 15. 1-15 • Often times, exercise is used as a means of mental relaxation • “Exercise high”: –Result of endorphins being released that can positively affect your attitude and outlook –Higher serotonin levels have been shown to improve mood, sleep/wake cycles, libido, and enhance feelings of well-being
  16. 16. 1-16 Benefits of Exercise in the Aging Process • Physiological and performance capabilities change as you age • Capabilities peak between ages 18-30 • A steady decline occurs after that peak
  17. 17. 1-17 If you maintain a greater fitness level throughout your lifetime, it is likely that you will have: –Greater strength –Greater flexibility –Greater cardiorespiratory health strength –Lower body fat percentage
  18. 18. 1-18 What Components of Fitness are Important to You? • Health-related components include: – Cardiorespiratory endurance – Muscular strength – Muscular endurance – Flexibility – Body composition
  19. 19. 1-19 Cardiorespiratory Endurance – Ability to persist in a physical activity requiring oxygen for physical exertion – Makes cardiovascular system more efficient Figure 1-5
  20. 20. 1-20 Muscular Strength – Ability or capacity of a muscle or group of muscles to exert force against resistance – Refers to a muscle’s ability to exert maximal force in a single effort – Strength is required in all types of activities Figure 1-6
  21. 21. 1-21 Muscular Endurance – Ability of a muscle to perform or sustain a contraction repeatedly over a period of time – Closely related to strength Figure 1-7
  22. 22. 1-22 Flexibility –The ability to move joints in arms, legs, and trunk freely through a full, non- restricted, pain-free range of motion –Important for: • Performance • Maintaining posture • Preventing injury
  23. 23. 1-23 Body Composition – Refers to the percentage of body fat relative to other lean tissues of the body – Excess fat is unhealthy Figure 1-9
  24. 24. 1-24 Body Composition (continued) – Obesity contributes/linked to: • Degenerative diseases • Psychological mal-adjustments • Shortened life – Balance between caloric intake and expenditure is critical for maintaining proper body fat content
  25. 25. 1-25 Speed – Ability to perform a particular movement very rapidly – Critical to be successful in many competitive athletic situations Power – Ability to generate great amounts of force against a particular resistance in a short period of time
  26. 26. 1-26 Neuromuscular coordination – Integration of senses with muscle function to produce smooth, accurate, skilled movements Balance – Ability to maintain some degree of equilibrium while moving or standing still Figure 1-13
  27. 27. 1-27 Agility • Ability to change or alter (quickly and accurately) direction of the body during activity Reaction Time • Time required to produce an appropriate and accurate physiological or mechanical response to external stimulus Figure 1-14
  28. 28. 1-28 Determining Your Reasons for Wanting to be Fit • Different for each individual • Prior to engaging in a fitness routine, determine your: – Personal reasons for fitness – Goal(s)
  29. 29. 1-29 Determining How Frequently You Engage in Physical Activity • Prior to initiating a program, determine –What your baseline is relative to your exercise habits –If you are devoting proper amounts of daily time to maintaining or developing your fitness
  30. 30. 1-30 How Long Will it Take You to Get Fit? • There are no shortcuts • Some improvements may be identified after a month of regular and appropriate activity • Plateauing is natural!
  31. 31. 1-31 • Make a commitment to your fitness • Once you achieve your goal, you will likely be motivated to maintain it after all your hard work • Physical fitness requires effort – especially for lasting effects
