Transcript of Assessing Special Population - Aging

If you wait to do everything until you're sure it's right, you'll probably never do much of anything. (Win Borden)

Aging and Fitness

U.S. population is aging Median

age (1990) = 32.9 years Median age (2000) = 35.3 years

1990-2000 saw increase in older adults (65+ years) from 32 million to 35 million Baby boomers will start retiring from

Need to promote physical activity in order to improve quality of life and

Aerobic Fitness

Declines with age during adulthood Decline in maximal heart rate is major contributing factor Other factors: decline in physical activity, reduction in muscle mass, increase in fat mass Cross-sectional data: decline is 0.4-.05 ml/kg/year Longitudinal data: decline is 0.04 to 1.43

Body Composition

Body weight and body fatness increase during adulthood BMI levels off around 45 years in men, and 55 years in women Percent fat levels off during 50s Increase in percent fat: combination

of fat mass increase fat-free mass decrease (especially muscle mass)


Maximal strength attained between 20 and 30 years of age Gradual decline thereafter (WHY?) Decline in activity appears to be major factor Manual workers appear to maintain strength during middle and later adult years Sedentary older adults can gain strength from training (Tai Chi)

Evaluating Adult Fitness

YMCA test battery (all adults) Army Physical Fitness Test (military personnel) AAHPERD Test (older adults) Senior Fitness Test (older adults) Groningen Test (older adults)

Ys Way to Physical Fitness

Fitness test battery Comprehensive fitness training program Normative database from over 20,000 adults Aerobic fitness

3-minute step test submaximal cycle ergometer test (multistage) sum of 3 skinfolds (converted to percent fat) sum of 4 skinfolds (converted to percent fat)

Body composition

Ys Way to Physical Fitness

Muscular strength

submaximal bench press test to fatigue 1-minute timed sit-up trunk flexion test

Muscular endurance


U.S. Army Physical Fitness Test (APFT)

Maintenance of fitness a requirement of military personnel APFT consists of three tests Criterion-referenced standards, provided for age and gender groups Alternative tests are available for medically excused personnel Personnel over 40 years require cardiovascular screening prior to testing

Army Physical Fitness Test

Push-up test

self-determined cadence maximum in 2 minutes self-determined cadence maximum in 2 minutes walking permitted, but discouraged

Sit-up test

2-Mile Run test

Army Physical Fitness Test

Alternate tests:

800-yard swim test 6.2-mile cycle ergometer test, 2 kilopond resistance 6.2-mile bicycle test 2.5-mile walk test not part of APFT, but must meet percent fat standards, or go on weight-loss program

Body composition

Functional Fitness

Important for older adults Capacity to meet demands of everyday functional activities Activities of daily living (ADLs) Dressing,

bathing, cooking, mobility

Important to independent living, reduction in health care costs

Computer Applications

Important for adult fitness settings Database management Recording workouts Monitoring progress Providing feedback (norm- or criterionreferenced) Exercise prescription

Biological Decline (Regression)

Chronological vs. Biological aging Body is aging continuously (conception death) After about age 30 Regression

in some form develops

Many theories attempting to explain Gerontology

Biological Theories of Advanced Aging

Def.: is the diminished capacity to regulate the internal environment, which results in a reduced probability of survival


Gabbard (2004)

Biological Regression and Motor Performance

Biological Regression and Motor Performance

Motor Behavior Peak

Performance (25-30)motor performance in several


activities Regression Usually

develops after the age of 30 Most physiological functions begins to show decrements

General rate at of 0.75 to 1 percent a year.

Fighting aging

Reasons of this loss physiological function: Inactivity Poor

health habits in movement patterns

Late adulthood Deterioration Walk,

run, jump


can it be delayed ? (Video Japan)
