Physical Activity and Exercise for Health and physical fitness

Page history last edited by Helena Baert 11 years, 6 months ago

Introduction

 

Physical Activity Levels have declined! According to the Healthy People 2010 report: 

  • More than 55% of US adults do NOT engage in the recommended amounts of activity
  • 25% are not active at all! 

 


Levels of physical activity[1]

 


Physical Activity on a Continuum

 

 

  • Physical activity = any body movement carried out by the skeletal muscles and requiring energy
  • Exercise = planned, structured, repetitive movement of the body designed to improve or maintain physical fitness
  • Physical fitness = a set of physical attributes that allows the body to respond or adapt to the demands and stress of physical effort

A few guidelines:

  1. For health promotion:
    4Expend about 150 calories—equivalent to 30 minutes of brisk walking—on most days
  2. For health promotion and weight management:

            4Engage in 45–60 or more minutes of activity on most days


Moderate Amounts of Physical Activity[2]

 


How much PA is enough?

 

<Moderate-intensity versus high-intensity exercise

<Continuous versus intermittent exercise
<Low-intensity exercise improves health but may not be very beneficial for improving physical fitness

 


Questions:

T/F: More than 55% of US adults do NOT engage in the recommended amounts of activity
