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

5

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

Physical Activity and Exercise for Health and Fitness

Improved immune function Prevention of injures and low-back pain Improved wellness for life

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
