. Physical activity define
Physical actvity: ususage of your skeletal muscles to alter the position of your body
physical fitness
improving muscular strength and endurance, flexibility, body composition, and cardiovascular endurance
exercise
planned structured and repeititve
the 5 general components of physical fitness
improving muscular strength and endurance, flexibility, body composition, and cardiovascular endurance
What are the US Physical Activity Guidelines and Healthy People 2020 physical activity
recommendations for adults and for children?
Adults: 30 minutes a day 5 days a week moderate to vigorous intensity
children: 60 minutes 5 days a week, moderate to vigorous activity
Differentiate between acute exercise and chronic exercise and between aerobic exercise and
resistance exercise.
Acute: short period of time (a one time thing: going to the gym once)
chronic: over longer periods of time (going to the gym every day)
aerobic: endurance and cardiovascular(all forms of exercises are aerobic since you always are need of oxygen to function)
anaerobic: less oxygen available in body, harder to develop energy
resistance: moving weight that strains muscle
What is meant by the FITT principle as it relates to exercise prescription
Frequency
Intensity
Time
Type
Measuring the intensity of physical activity poses one of the greatest challenges for surveillance and
intervention studies. How are light, moderate, and vigorous intensity activities typically defined (in
METs)? What is a MET?
Met is the metabolic equivilent of a task, they are defined in # MET. for example 1 Met is being at rest and sitting
2 METS is lightly walking
3 METS is moderate activity
4 METS is vigorous activity
what are the leading non-communicable diseases?
heart disease, diabetes, cancer, Chronic repotory disease, ASthma, diabetes
What were the general findings from the London conductor and bus driver epidemiological studies?
those with professions which include alot of mobility such as train conductors who move around alot, tend to have a longer life-span and overall better health
- Who is considered the father of physical activity epidemiology?
jeremy N norris
- What were the studies that established critical relationships between work-related physical activity,
leisure-time physical activity, and cardiorespiratory fitness with morbidity and mortality associated
with cardiovascular disease?
san francisco long-shoremen
Harvard alumni
cooper institute
. More recently, experts are concerned about a troubling human behavior that was not captured in the
original epidemiological studies of physical activity and exercise. What is this behavior?
sedentary behavior, which is a direct result of technological advancements, office jobs, etc/…
What is the nature of the relationship between sitting, cardiorespiratory fitness, and moderate-to vigorous physical activity with the relative risk for all-cause mortality?
as sitting increases CR fitness decreases MTV physical activity decreases, and risk for all -cause mortality increases
