									Physical Activity Across the Lifespan

   Janet Purath, PhD, APRN, BC

Objectives

       o Describe physical activity levels across
         the lifespan and across the globe

       o Discuss types of physical activity

       o Discuss health benefits of physical
         activity
         Importance of Changing
            Health Behaviors
o Shift from infectious disease to chronic and/or
  degenerative illnesses emphasizes the need for
  primary, secondary and tertiary prevention
o Healthy behaviors lead to:
  – Increased longevity
  – Reduced disability rates
  – Better mental health and cognitive function
  – Lower healthcare costs
        Definition and Significance
o 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.

Physical Activity Recommendations

   o Everyone should participate in a
     minimum of 30 minutes of
     physical activity every day.

   o Young people are encouraged to
     aim for 60 minutes of physical
     activity per day.
Modes of Physical Activity
     o Lifestyle

       – Work

       – Leisure

       – Household

     o Transportation

     o Exercise
Types of Physical Activity

   o Aerobic

   o Muscle strengthening

   o Bone Strengthening

   o Balance

   o Flexibility
             Risk Populations

o Global trends in physical inactivity are of
  particular concern in certain high risk
  populations – Older adults, women and
  young people.

                Older Adults

o World-wide population is aging.

o By 2030, 55 countries are expected
  to see their 65 and older populations
  at least 20 percent of their total.

o 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
  o Improved:
     – Function and quality of life
     – Balance and strength
     – Coordination and motor control
     – Flexibility
     – Endurance
     – Mental health and cognition
  o Decreases risk of falls
  o More interaction with people of all ages
                 Sarcopenia

o Definition
o Consequences
  – decreased in resting energy expenditure
  – decreased insulin sensitivity
  – diminished muscle strength
  – increased risk of disability and falls
  – increased risk for mortality
            Recommendations
o 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

                                                     Activity for Low-income
  Physical Activity and Young People
o 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.
