Physical Activity Across the Lifespan Janet Purath, PhD, APRN, BC Michele Shaw, PhD, RN
Objectives • Describe physical activity levels across the lifespan and across the globe • Discuss types of physical activity • Discuss health benefits of physical activity
Importance of Changing Health Behaviors • Shift from infectious disease to chronic and/or degenerative illnesses emphasizes the need for primary, secondary and tertiary prevention • Healthy behaviors lead to: • Increased longevity • Reduced disability rates • Better mental health and cognitive function • Lower healthcare costs
Definition and Significance • Physical activity: • Defined as any bodily movement produced by skeletal muscles that requires energy expenditure. • Lack of physical activity is an independent risk factor for chronic diseases, and overall is estimated to cause 1.9 million deaths globally. • Source: WHO: Global Strategy on Diet, Physical Activity and Health
Why are people inactive? http://www.wcc-coe.org/wcc/what/jpc/pictures/mumbai1-low.gif cai.blogware.com/_photos/Smog.jpg
Physical Activity Recommendations • Everyone should participate in a minimum of 30 minutes of physical activity every day. • Young people are encouraged to aim for 60 minutes of physical activity per day.
Modes of Physical Activity • Lifestyle • Work • Leisure • Household • Transportation • Exercise
Types of Physical Activity • Aerobic • Muscle strengthening • Bone Strengthening • Balance • Flexibility
Risk Populations • Global trends in physical inactivity are of particular concern in certain high risk populations – Older adults, women and young people. http://www.who.int/dietphysicalactivity/pa/en/index.html
Older Adults • World-wide population is aging. • By 2030, 55 countries are expected to see their 65 and older populations at least 20 percent of their total. • By 2040, the global population is projected to number 1.3 billion older people—accounting for 14 percent of the total.
Evidence of Benefits for Older Adults • Improved: • Function and quality of life • Balance and strength • Coordination and motor control • Flexibility • Endurance • Mental health and cognition • Decreases risk of falls • More interaction with people of all ages
Sarcopenia • Definition • Consequences • decreased in resting energy expenditure • decreased insulin sensitivity • diminished muscle strength • increased risk of disability and falls • increased risk for mortality
Recommendations • Older adults should engage: • in moderate intensity activity at least 150 minutes or 75 minutes of vigorous activity per week • in strength activities 2 or more days per week. • in balance activity if they have risk for falls • Source: 2008 Physical Activity Guidelines for Americans
Physical Activity and Women • Why is this important? • Benefits • Decrease in specific diseases • Improved mental health and self esteem
Activity for Low-income and Rural Women http://www.waterencyclopedia.com/Da-En/Developing-Countries-Issues-in.html
Physical Activity and Young People • Why is this important? • Active children are more likely to grow up to be active adults. • Increased activity = positive health outcomes • Controlling weight • Decreasing blood pressure • Lessons risk of diabetes & some cancers • Reduces asthma symptoms and severity • Psycho-social benefits
Physical Activity and Young People • All children ages 2 and older should participate in at least 30 minutes of age appropriate physical activities every day. • 5-18 year olds should aim for a minimum of 60 minutes of moderate to vigorous physical activity each day.
Definitions for Young People • Aerobic • Muscle Strengthening • Bone Strengthening
What activities count? • Moderate Intensity Aerobic Activities: • Children: • Bicycle riding • Walking • Active recreation • Adolescents: • Yard work or house work • Playing games involving catching/throwing • Brisk walking • Active recreation
What activities count? • Vigorous-Intensity Aerobic Activities: • Active games including running & chasing • Bicycling • Running • Vigorous Dancing • Sports (swimming, basketball, soccer)
What activities count? • Bone-Strengthening Activities: • Jumping, hopping, skipping • Running • Jumping rope • Sports: gymnastics, basketball, volleyball, futbol
Encouraging Physical Activity Among Young People • Adults as positive role models • Provide equipment • Encourage play with friends • Make activity part of family life • Require safety (bike helmets, wrist/knee pads, traffic issues, environmental considerations)
Summary Increasing Physical Activity across the lifespan and across the globe can significantly improve world health.
