Lesson 1 The Role of Exercise in Health
Describe and apply the American College of Sports Medicine
(ACSM) and American Heart Association (AHA) guidelines for
physical activity in adult and older adult populations.
The AHA guidelines for physical activity includes moderately-intense
cardiovascular aerobic exercise for 30 minutes x 5 days a week OR
vigorous exercise for 20 minutes x 3 days a week. 8-10 strength training
exercises with 8-12 reps, 2x a week. Decrease sedentary activities such
as watching TV. Also is advised to receive cardiac clearance prior to
initiating new exercise regimen in those that were previously sedentary.
The ACSM guidelines for physical activity suggests that all adults ages
18-65 should have 150 minutes of aerobic activity and 2 days per week of
strength training per week.
The American college of sports medicine (ACSM) takes a broad approach
on physical activity and its impact on overall health, fitness, and function,
while AHA focuses more on using exercise and physical activity to
decrease risks of cardiovascular morbidity and mortality. The AHA’s
recommendations on quantity of exercise is similar to that of ACSM but
is focused on the general public’s bare minimum recommendation, while
ACSM utilizes the FITT approach for individualized “exercise
prescription”. When it comes to older adults, both put an emphasis on
independence, safety, and fall prevention. To summarize: AHA =
community/public health focus; ACSM = clinical/exercise professional
focus
Identify the FITT (frequency, intensity, time, type) principles of
an exercise prescription.
Frequency- how many times you do an exercise each week or
month (EX: “I walk 7 days a week and I lift weights 3 times a
week”)
