Chapter 2 Part B - Benefits and Risks of PA Flashcards
leaders in Public Health PA recommendations
American College of Sports Medicine, CDC, U.S. Surgeon General, NIH
Goal of recommendations
improve health, lower morbidity, reduce mortality
morbidity
susceptibility to disease and injury
mortality
death
2018 PA Guidelines general statement
move more, sit less
2018 PA Guidelines for Americans time for moderate aerobic activity
150-300 minutes a week
2018 PA Guidelines for Americans time for vigorous aerobic activity
75-150 minute a week
2018 PA Guidelines for Americans time for muscle strengthening
2 days a week
more risk you take of physical activity, the more likely you are to
be injured
MET stands for
metabolic equivalent of task
MET
level to which an activity increases energy expenditure compared to rest expenditure
1 MET equals
energy expenditure when the body is at rest
1.5-3 METs =
light intensity activity
3-6 METs =
moderate intensity activity
6+ METS =
vigorous intensity activity
PA for preschoolers
everyday throughout the day in active play
PA for children and adolescents
60 minutes a day and 3 days a week of vigorous, strengthening activity
PA for adults
150 minutes a week, 2 days of strengthening
PA for Seniors
150 minutes a week, 2 days of strengthening, balance training
improved CV and Respiratory Function leads to an increase in
VO2 max, capillary density, lactate threshold
improved CV and Respiratory Function leads to a decrease in
Minute Ventilation, Myocardial VO2, Heartrate, Blood Pressure
Physical activity increases what type of cholesterol
HD (good) cholesterol
Physical Activity increases or decreases glucose tolerance
increases
what risk factors does PA decrease?
resting body pressure, total body fat, intraabdominal fat, insulin requirement, triglycerides, inflammation
what change in PA brings the biggest change in health?
going from nothing to something
risks associated with PA and exercise
injury and cardiovascular complications
greatest risk for CVD is in what type of activity
vigorous
Sudden Cardiac Death is also called
cardiac arrest
Acute Myocardial Infarction is also called
heart attack
what are ways to prevent exercise-related CVD?
awareness of conditions, symptoms, and family history, screening, modification of program as needed, proper emergency training
the risk of mortality based on sedentary behavior is independent of
Physical Activity
