KNH 188 Exam 2 Review: Physical Activity and Health
PA activity - ANSWER > Any bodily movement produced by skeletal muscles that expends
energy.
Exercise - ANSWER > A type of PA that is structured, planned, and repetitive body movement
that improves or maintains physical fitness.
Physical fitness - ANSWER > Ability to carry out daily tasks with vigor and alertness, without
undue fatigue, allowing room for enjoyment of leisure activities.
Cardiorespiratory Endurance - ANSWER > Ability to perform prolonged large muscle dynamic
exercise at moderate to high level of intensity.
Muscular strength - ANSWER > Ability of muscle to exert maximum force.
Muscular endurance - ANSWER > Ability of muscle to exert submaximal force repeatedly over
time without losing quality.
Flexibility - ANSWER > The ability of joints to move through their full range of motion.
Body Composition - ANSWER > The proportion of fat and non-fat mass in the body.
PA recommendations for adults - ANSWER > Adults should do 300-150 minutes a week of
moderate exercise or 150-75 minutes of vigorous exercise per week, plus strength training twice
a week.
PA recommendations for older adults - ANSWER > Same as adults but should incorporate
balance training.
, PA recommendations for children/teens - ANSWER > Ages 6-17 should receive 60 minutes of
moderate to vigorous exercise daily, plus strength training 3 times per week.
Acute conditions - ANSWER > Conditions that develop suddenly and usually only last a short
time.
Chronic conditions - ANSWER > Conditions that develop slowly and persist over time.
Effects of PA on blood pressure - ANSWER > Immediate reduction in blood pressure following a
single bout of exercise.
Effects of PA on blood cholesterol - ANSWER > Exercise enhances skeletal muscle's ability to
use lipids for fuel, reducing the amount of fats in the blood.
Effects of PA on diabetes - ANSWER > PA helps to increase insulin sensitivity by reducing body
fat.
Long term consequences of chronic inflammation - ANSWER > High levels of inflammation
long term damages tissues, leading to fatigue, mood disorders, and frequent infections.
Effects of PA on the brain - ANSWER > Improves cognition, quality of life, reduces depression
and anxiety, and improves sleep.
PA as secondary prevention - ANSWER > Example of PA as a secondary prevention is cardiac
rehab after a myocardial infarction.
Exercise and health care costs - ANSWER > Exercise is linked to lower health care costs by
preventing disease and injury.
