McGraw-Hill/Irwin
7-2
INTRODUCTION
• Importance of the relationship between physical activity and health
• Sedentary living >
Chronic disease >
Greater risk of premature death
• Increased health care cost
• Rates of overweight/obese children and youth
7-3
What is “Health-related Fitness”?
Fitness that helps prevent and remediate disease and illness leading to a better quality of life
A CONTEMPORARYUNDERSTANDING OF FITNESS
7-4
What is “Motor Performance (skill-) related Fitness”?
Fitness needed for performing well in sports and work, that requires physical skill, strength, and/or endurance
A CONTEMPORARY UNDERSTANDING OF FITNESS (Cont’d.)
7-5
What is your definition of “Health?”
Traditional view:
Contemporary view:
Absence of disease and illness
Links health with “wellness” which is multidimensional: Emotion, intellect, interpersonal, spiritual, social, and environmental
A CONTEMPORARY UNDERSTANDING OF FITNESS (Cont’d.)
7-6
Health-related Fitness
A CONTEMPORARY UNDERSTANDING OF FITNESS(Cont’d.)
• Linked to several “hypokinetic” diseases, and other condition related to obesity
(e.g., Type II diabetes)
• Components:
Cardio-vascular capacity (aerobic endurance)Muscular strengthMuscular endurance FlexibilityBody composition (i.e. % body fat)
7-7
Health-related Fitness (Cont’d.)
A CONTEMPORARY UNDERSTANDING OF FITNESS(Cont’d.)
• Core stability and flexibility are key
Benefits of strength conditioning?
Bone-mineral density Body composition Muscular strength Glucose metabolism Serum lipids Maximal oxygen consumption Basal metabolism
7-8
Health-related Fitness (Cont’d.)
A CONTEMPORARY UNDERSTANDING OF FITNESS(Cont’d.)
• Benefits of moderate vs. vigorous intensity activities
• Developing and maintaining fitness . . .“There is no is no off-season”
7-9
Motor Performance (skill-) related Fitness
A CONTEMPORARY UNDERSTANDING OF FITNESS(Cont’d.)
Components:• Agility
• Balance
• Coordination
• Power
• Reaction time
• Speed
7-10
Motor Performance (skill-) related Fitness
A CONTEMPORARY UNDERSTANDING OF FITNESS(Cont’d.)
• Different activities require a different emphasis
Fitness Conditioning differences between . . .
Gymnastics?Football?
Tennis? Golf?
7-11
COSMETIC FITNESS
• People differ in their reasons for desiring fitness
• Cultural norms differ and change over time relative to fitness, appearance
• Can pose risk of eating disorders
• “Cult of slenderness” (Tinning, 1985)
7-12
THE DOSE–RESPONSE DEBATE
Focuses on the question:
What “dose” of exercise is necessary to achieve the beneficial health “responses?
“Exercise epidemiology” studies the relationship of physical activity to all causes of mortality
7-13
THE DOSE–RESPONSE DEBATE (Cont’d.)
The FITT Formula:
•Frequency of exercise
•Intensity of exercise
•Time spent exercising
•Type of exercise
Can be applied to all components of health-fitness!
7-14
THE DOSE–RESPONSE DEBATE (Cont’d.)
The FITT Formula: (cont’d.)
• Its application differs based on a person’s fitness goals, health status, and age
• U.S.D.H.H.S. PA Guidelines for children and youth
(http://www.health.gov/paguidelines/guidelines/default.aspx)
• Role of Moderate-to-Vigorous Physical Activity (MVPA)
7-15
THE SOCIAL GRADIENT IN HEALTH AND FITNESS
“Social gradient in health”: •The health status of a particular class within a nation is typically better than that of the classes below it and worse than that of the classes above it (Hertzman, 1994)
•. . . relative social and economic deprivation within societies accounts for better or poorer health
7-16
THE SOCIAL GRADIENT IN HEALTH AND FITNESS(Cont’d.)
Traditional view of fitness:
•Viewed as a responsibility of the individual
Socio-ecological view of fitness:
•Social contexts within which people live their lives as partial explanations for their levels of health and fitness
7-17
THE SOCIAL GRADIENT IN HEALTH AND FITNESS(Cont’d.)
Socio-ecological model of health promotion
(Adapted from Stokol, 1996)
7-18
THE SOCIAL GRADIENT IN HEALTH AND FITNESS(Cont’d.)
Socio-ecological view fitness and health:
•View fitness and health as both an individual and social issue •Goal: Increase access to safe, affordable, and inclusive opportunities to pursue a physically active lifestyle FOR ALL
7-19
FITNESS-TRAINING CONCEPTSAND PRINCIPLES
General Training Principles:
F.I.T.T. formula should applied using
•Specificity
•Progressive overload
•Recovery time
7-20
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
Health-Fitness Training
• Targets all health-fitness components:
CV Endurance (Moderate intensity)
Muscular strength (especially core!)
Flexibility
• High intensity activities are a turn-off for most all
7-21
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
Continuous and Interval Training
Continuous Training: Exercise with HR is sustained at or just above threshold level for 30 min. (preferred), 15 min. (at minimum); 3 times p. week; preferable for beginners
Interval Training: Vigorous exercise bouts are interspersed with rest periods (more intense)
7-22
Anaerobic Training:
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
• Short duration exercise (w. intervals of rest) without taxing the aerobic (O2) energy system
• Can build muscle mass, bone density, lower resting metabolic rate
• Main outcome – Move quickly and deliver great force
7-23
Strength Training:
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
• Programs vary the following variables:
Amount of resistance per lift
# of reps per set
# of sets per workout
# of workouts per week
7-24
Strength Training:
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
• Muscular endurance: Lower resistance Higher # of reps
• Muscular strength: Higher resistance Lower # of reps
EXPERTS:Weight loads at or
exceeding 75 percent of one’s maximum lifting capacity are
most beneficial for developing & Maintaining strength
7-25
Flexibility
FITNESS-TRAINING CONCEPTS AND PRINCIPLES(Cont’d.)
• Essential (but often neglected) component
• Static flexibility: Range-of-motion limit around a joint
• Dynamic flexibility: Rate of increase in muscle tension as it is stretched
• Recommendation: 3 times p. week after the main activity
7-26
THE MEASUREMENT OF FITNESSAND PHYSICAL ACTIVITY
Considerable debate on the merits of different methods
What makes a fitness program effective . . .
. . . for a Soccer player?
. . . for a golfer?
. . . for you?
It depends on the goal . . . . . . Performance? . . . Looks? . . . Health?
7-27
THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
FITNESSGRAM & ACTIVITYGRAM:
The most complete program for formally assessing health-related fitness and physical fitness and physical activity
7-28
THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
FITNESSGRAM TEST COMPONENTS:
•Aerobic capacity (PACER, 1 mile, walk)
•Body composition (BMI, Bioelectric Impedance Analysis)
•Abdominal strength/-endurance (Curl-ups)
•Upper-body strength/-endurance (Push-ups, modified pull-ups, or the flexed-arm Hang)
•Flexibility (trunk lifts, back-saver sit and reach, shoulder stretch)
Which do you think is the most important indicators of health-related fitness? Why?

THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
Methods of reporting test results:
Norm-referenced scoring:
Score is reported relative to that of the performance of the larger group of peers
Criterion-referenced scoring:
Score is reported relative to a criterion (i.e., standard) believed to produce health benefits or reduced risk of health problem
7-31
THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
Methods of reporting test results: (Cont’d.)
Zones of interpretation:Use fitness-performance or physical activity data to understand whether you are at risk for hypokinetic disease,
at a level that will contribute to health, or
at a level necessary for some athletic performance
7-32
Measuring Moderate-to-Vigorous Physical Activity (MVPA):
Options:
•Heart rate monitor•Accelerometer•Pedometer•Activitygram •Estimate caloric expenditure (METS)
THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
7-33
Acceptable reasons to fitness testing in schools: •Fundamental part of fitness instruction
•Should be used to assess the quality of fitness instruction and student learning
•all students should be able to meet health-related fitness standards
THE MEASUREMENT OF FITNESS ANDPHYSICAL ACTIVITY
(Cont’d.)
7-34
Informal Measurement of Fitness
•Take heart rate during exercise
•Take heart rate after exercise to determine recovery (quicker recovery = better fitness)
•Keep track of distance and time for the same kind of exercise
