What is Physical Fitness? The body’s ability to respond or
adapt to the demands and stress of physical effort
Health-related fitness: 5 components Cardiorespiratory endurance Muscular strength Muscular endurance Flexibility Body composition
3
What is Physical Fitness? Cardiorespiratory Endurance - ability to perform
prolonged, large-muscle, dynamic exercise at moderate to high intensity
Muscular Strength - amount of force a muscle can produce with a single maximum effort
Muscular Endurance - ability to resist fatigue and sustain a given level of muscle tension
Flexibility - ability of joints to move through their full range of motion
Body Composition – proportion of fat and fat-free mass (muscle, bone, and water) in the body
Skill-Related Components of Fitness – speed, power, agility, balance, coordination and reaction time. Tends to be sport specific

Physical Activity and Exercise for Health and Fitness The Centers for Disease Control and
Prevention (CDC) recent statistics about American adults: About 31% participate in some leisure-time
physical activity Between 2003 and 2009, that leisure-type
physical activity decreased by nearly 6% Physical activity levels are higher in men than in
women but decline with age in both Levels are lower in Hispanics, American Indians,
and blacks than in whites People with higher levels of education are more
active. 54% of college grads exercise regularly compared to 31% of high school dropouts

The Benefits of Exercise
Improved cardiorespiratory functioning More efficient metabolism and
improved cell health Improved body composition Reduced risk of premature death
6
Disease Prevention and Management
Cardiovascular Disease Prevention = Exercise
Improves cholesterol levels Improves blood pressure Improves insulin resistance Interferes with the disease itself Lowers risk of heart disease and stroke
Cancer Osteoporosis Type 2 Diabetes

Improved Psychological and Emotional Wellness
Reduced anxiety and depression Improved sleep Reduced stress Enhanced self-esteem and sense of self-efficacy Enhanced creativity and intellectual functioning Improved interpersonal wellness

Cardiorespiratory Endurance Exercises Frequency - 3-5 days per week Intensity
Maximal oxygen consumption (VO2max) Target heart rate range
Duration - 20-60 minutes per workout Type The warm-up and cool-down

Developing Muscular Strength and Endurance
Types of strength training exercise Resistance exercise
Isometric (static) exercise Isotonic (dynamic) exercise
Choosing equipment Choosing exercises Frequency Intensity and time
A caution about supplements
