Intro to Physical Activity
Generally: movement of the body caused by skeletal muscle contractions, in public health: types of movements that have health benefits.
What is physical activity?
While there is some evidence of the health benefits of muscle strengthening activities, there is much more evidence on health benefits of this type of physical activity.
What is aerobic activity?
The government agency that produced the 2008 and 2018 Physical Activity Guidelines for Americans.
What is U.S. Department of Health and Human Services?
These types of approaches to promoting physical activity focus on increasing physical activity by providing information to motivate and enable people to change behavior and maintain that change.
What are informational approaches?
Walking at 3- 4.5 miles per hour is considered to be this type of intensity exercise.
What is moderate-intensity exercise?
Term typically used by scientists to refer to the subset of physical activity that is done for the purpose of increasing physical fitness.
What is exercise?
The volume of aerobic activity can be thought of as the product of frequency (number of sessions per week), duration (time spent active each session), and this, the MET value of the activity.
What is intensity?
The Physical Activity Guidelines for Americans recommends this many minutes of moderate-intensity physical activity each week for adults.
What is 150?
These types of approaches to promoting physical activity include community based interventions that teach skills and mobilize support as well as make changes to the settings to accommodate more physical activity.
What are behavioral and social approaches?
Creating a buddy system, joining an exercise group, or joining a workplace physical activity challenge are examples of this type of behavioral and social approach.
What are social support interventions in community settings?
A well known physiologic effect of physical activity is that it expends energy, often measured in this.
What is kilocalories? (or abbreviated as calories)
Physical activity has been proven to reduce the risk of this chronic disease which is characterized by a chronic elevation in blood glucose (called hyperglycemia).
What is diabetes?
The Physical Activity Guidelines for Americans recommends this many minutes of moderate- to- vigorous physical activity this many days per week for children and adolescents.
What is 60 minutes daily?
These types of approaches to promoting physical activity provide access to places where people can be physically active and often involve efforts of employers, schools, coalitions, government agencies, and community members.
What are environmental and policy approaches?
Signs posted by elevators or escalators to encourage people to use the stairs is this type of an informational approach.
What is a point-of-decision prompt?
Refers to the physiologic capacity of systems of the body that are affected by physical activity. Some measures of this are aerobic capacity, muscle strength and endurance, and flexibility.
What is physical fitness?
There is a this kind of relationship between amount of physical activity and health benefits. Greater amounts of physical activity produce greater health benefits.
What is a dose-response relationship?
In addition to aerobic activity, the guidelines also recommend these other two types of activities for children and adolescents.
What are muscle and bone strengthening activities?
When it comes to community design, greater street connectivity, traffic- calming amenities, increased density of homes, work, and retail, and greater land use mix are all associated with this.
What is increased walking and biking?
According to the 2018 Physical Activity Guidelines for Americans 2nd edition, approximately this percentage of adults meet the physical activity recommendations.
What is about 20%
One of the three sources of energy expenditure that relates to the energy expended just to keep the body alive.
What is basal energy expenditure? (measured using basal metabolic rate)
Physical activity can reduce this type of cholesterol, the type of cholesterol that increases risk of cardiovascular disease.
What is low-density lipoprotein (LDL) cholesterol?
Intensity of exercise can be defined in two ways: absolute, which is commonly based on the type of activity and this, which uses a person’s level of cardiorespiratory fitness to assess level of effort.
What is relative intensity?
Dr. David Satcher, former Surgeon General of the United States stated “success in public health work requires" this
What are partnerships?
The observation that physical activity protects against heart disease was first made by Jeremy Morris in a study comparing these two occupations, one sedentary and one active.
What are drivers and conductors?
