Basic Principles of Physical Fitness HEALTH Chapt. 4
Slide 2-

Physical Activity and Exercise for Health and Fitness Physical activity levels have declined Healthy People 2010: More than 55% of U.S. adults do not engage in recommended amounts of activity 25% are not active at all
Slide 3-

Levels of Physical Activity
Slide 4-

Physical Activity on a Continuum Physical activity: any body movement carried out by the skeletal muscles and requiring energy Exercise: planned, structured, repetitive movement of the body designed to improve or maintain physical fitness Physical fitness: a set of physical attributes that allows the body to respond or adapt to the demands and stress of physical effort
Slide 5-

Lifestyle Physical Activity For health promotion: Expend about 150 calories—equivalent to 30 minutes of brisk walking—on most days For health promotion and weight management: Engage in 60 or more daily minutes of activity to prevent unhealthy weight gain Engage in 60-90 daily minutes of activity to sustain weight loss
Slide 6-

Moderate Amounts of Physical Activity
Slide 7-

Exercise to Develop Physical Fitness Lifestyle physical activity improves health but may not improve fitness A structured, formal exercise program improves physical fitness and provides even greater health improvements
Slide 8-

How Much Physical Activity Is Enough? Moderate-intensity versus high-intensity exercise Continuous versus intermittent exercise Low-intensity exercise improves health but may not be very beneficial for improving physical fitness

How Much Physical Activity Is Enough?

Health-Related Components of Physical Fitness Health-related fitness = physical capacities that contribute to health Five components: 1. Cardiorespiratory endurance = the ability of the body to perform prolonged, large-muscle, dynamic exercise at moderate-to-high levels of intensity
Slide 11-

Health-Related Components of Physical Fitness 2. Muscular strength = the amount of force a muscle can produce with a single maximum effort 3. Muscular endurance = the ability of a muscle or group of muscles to remain contracted or to contract repeatedly 4. Flexibility = the range of motion in a joint or group of joints
Slide 12-

Health-Related Components of Physical Fitness 5. Body composition = the proportion of fat and fat-free mass (muscle, bone, and water) in the body

Specificity—Adapting to Type of Training The body adapts to the particular type and amount of stress placed on it To develop a particular fitness component, perform exercises specifically designed for that component
Slide 15-

Progressive Overload—Adapting to Amount of Training Placing increasing amounts of stress on the body causes adaptations that improve fitness; progression is critical FITT principle for overload: Frequency—How often Intensity—How hard Time—How long (duration) Type—Mode of activity
Slide 16-

Reversibility—Adapting to a Reduction in Training Fitness improvements are lost when demands on the body are lowered If you stop exercising, up to 50% of fitness improvements are lost within 2 months
Slide 17-

Individual Differences— Limits on Adaptability Everyone is NOT created equal from a physical standpoint There are large individual differences in ability to improve fitness, body composition, and sports skills
