Healthy People
was a 10 year government sponsored program started in 2000 designed to improve the nation's
health. The program set specific objectives for adults in order to get them moving and physically
active.
Objectives of Healthy People included:
reducing the number of adults who failed to engage in leisure-time physical activity, double the
number of adults who engaged in at least 30-minutes of activity daily, and increase the number of
adults who participated in some type of resistance exercise to build muscle and endurance.

Steps to a fitness routine that can be maintained long term:
1) variety
2) accountability
3) specific goals
4) rewards
5) disease prevention
As we age, we should focus on _________________________, ___________________, and

An individual should start with ___________ minutes of activity a day to easy into a fitness routine
(may be done in small intervals throughout the day)

3 components to any fitness program:
1) aerobic workout
2) resistance training
3) stretching and flexibility
aerobic workout:
should be performed for 20-60 minutes a day 5 days a week. Goal is to increase your heart rate.
Heart rate:
, calculation of heart beats per minute. Count your pulse for 10 seconds and multiply by 6
Maximum Heart Rate:
subtract your age from 220 (i.e. 40 years old= 220-40= 180 bpm)
Target Zone:
60-90% of your maximum heart rate (i.e. 180 x 0.6 = 108 bpm to 180 x 0.9= 162 bpm)
You want to reach your _____________________________ not your ____________________.
target zone; maximum heart beat
Goal of aerobic activity is to:
build endurance, which increases the ability to deliver oxygen throughout the body. They should start
with 5-10 minutes of stretching with low intensity to warm up the muscles.
Resistance exercises:
goal is to maintain muscle (strength training). Helps to retain lean muscle mass. After age 20-30 we
start to lose the lean muscle mass as part of natural aging process.
A combination of aerobic exercise, resistance training, and stretching will:
increase your basal metabolic rate and calories will be burned more efficiently.
________________ is the first source of energy for cells.
Adenosine triphosphate (ATP)
energy is released from food used to convert ___________________ to adenosine triphosphate (ATP)
through the addition of a phosophate group.
adenosine diphosphate (ADP)
the resting muscle can store enough ATP to do work for approximately ___________________
seconds
2-4
anaerobic activity is done without ______________
