Defining Fitness • Health Fitness • prevention and remediation of disease • includes physical and mental • Motor-Performance • focused on sport performance • requires physical skill and strength
Health Fitness • Importance of aerobic exercise • Kenneth Cooper • Focus on strength and flexibility • Benefits of resistance training • Flexibility • Static • Dynamic
Motor-Performance Fitness • Purpose is to perform sport skill • Minimal impact to health fitness • Importance of functional specificity • strength in relation to the task
Cosmetic Fitness • Goal of looking good • Attractive physical appearance • fitness look is “in” • Increases active lifestyles • Acceptance of various body shapes
The Dose-Response Debate • Intensity • focuses on target heart rate • Duration • amount of time sustaining target heart rate • Frequency • focus on recovery and rebuilding
Current Exercise Prescription • Adults • accumulation of 30 minutes of daily activity • moderate intensity • Children • double adult suggestions • typically in short bouts with resting between
Fitness Levels Among Children and Youths • Results from NCYFS I (1985) • 8,800 subjects • body composition (increase in body fat) • cardiopulmonary measure (increased times) • Results from NCYFS II (1987) • 4,853 subjects • results similar to NCYFS I
Activity Patterns Among Children and Youths • Ten conclusions from research (see p. 191) • Activity reduces with age • Establish good habits early • Decrease in sport after age 11 • Teen years influence adult behaviors
Fitness Levels Among Adults • Difficult to obtain data (Adults aren’t in school) • American Sports Data • several key findings (p.192) • Examine risk factors - inactivity is a major threat • Activity level more important than fitness level • Fitness boom confined by class (upper and middle class phenomenon)
Fitness and Activity Patterns Among Older Adults • Older citizens becoming more active • Resistance exercise (weight training for all) • Aerobic conditioning • Significant psychological benefits • Future research field - appropriate exercise for older adults
Fitness and Physical Activity Programs for Children and Youths • Schoolwide programs • Fitness clubs • Fitness-remediation programs • Home-based fitness • Daily fitness programs • Fitness courses
Fitness and Physical Activity Programs for Children and Youths • Fitness focus in Physical Education • Fitness elective courses • Fitness centers • High school fitness program • State requirement approach • Need to be creative!
Comprehensive Schoolwide and Community-Linked Programs • CATCH • Healthy Lifestyles • Districtwide Wellness Initiative • Community recreation center • Collaboration for Intramural Sports • AAHPERD initiatives (e.g. Fitnessgram, JFH, HFH, etc.)

Informal Home-Based Fitness • Videotape workouts • Home-fitness equipment • Bicycles (mountain and road) • Walking and aerobic dance • Free weights
Physical Fitness Instruction • No national certification • Organizations offer certification • Most fitness instructors have no training • American College of Sports Medicine • three different certification levels • two clinical certifications
Fitness Certifications • Strength and Conditioning Certification • bachelors degree and CPR • certification • YMCA Fitness Instructor Certifications • Bachelor’s Degree in Adult Fitness • Physical Therapy • Master’s Degree in Fitness
The Costs of Inadequate Health Fitness • High costs both social and economic (pp. 212-213) • Poor fitness employees greater health problems than fit employees • Increase in medical costs (For children 6-17 costs associated with obesity have tripled in last 20 years to $127 billion/year) • Worker’s compensation increases • Data suggests not an individual issue
Fitness Behavior: Short and Long Term • Increased public awareness (Challenge is to change beliefs into behaviors!) • Sufficient intensity, duration, and frequency • Commitment to sustained involvement • Change in lifestyle • Quick fix programs tend to fail • Forcing fitness on children tends to fail!
Developing a Fitness-Educated Public • Average individual needs fitness education • Media myths • ideal image of a fit person • fitness miracles can occur quickly • celebrity status and instant experts • Knowledge explosion needs to occur • Ideal source: school physical education
Equity Issues in Fitness and Activity • Issues of gender, race and socioeconomics • Impact of obesity and physical inactivity • Urban settings and activity levels • Importance of neighborhood programs • Increased focus on women’s issues
Fitness Tests or Activity Estimates? • Value of moderate activity levels • Importance of daily activity measures • Mass fitness testing can be counterproductive • Suggested testing guidelines (Dev. Approp.?) • Test to identify at-risk children • Criterion-referenced standards • Activity evaluation • Self-testing instead of mass testing • Test for diagnosis and providing feedback
Fitness and Aging • American population is aging • Maintain productive living capacity • Activities are available • Disadvantage is ingrained lifestyles • Need better information to seniors • Incorporate more programs • Provide more publicity
Fitness Issues in Physical Education • Physical fitness in schools is complex (See Corbin quote p. 220) • Implementation ranges from high to low • Focus of physical education programs should be “health related fitness”? • Main barrier perceived as lack of time in school - creative solutions needed!
Toward a Physical Activity Infrastructure for the United States • Move from remediation to prevention • Develop and sustain active lifestyles • Change involves social context (i.e. race and gender issues) • Public-policy initiatives must occur (PEP Grants?)
