F.I.T.T. Principles and METsF.I.T.T. Principles and METs
Cardiovascular ExerciseCardiovascular Exercise
Aerobic (requiring oxygen) activities that utilize large muscle groups for long periods
of time Walking, jogging, biking, swimming These activities increase HR to a rate that can be sustained over a period of time.
Benefits of Cardio Exercise cont’Benefits of Cardio Exercise cont’ Increase in Lean muscle mass – more
efficient oxygen use Improved cardio respiratory function Helps with depression, anxiety, stress Helps decrease the loss of lean body
massCounteracts decrease in metabolism
seen with dieting
Benefits of Cardio Exercise cont’Benefits of Cardio Exercise cont’Reduce fatigue with daily activities/
increase energyHelps keep strong bones, decrease
osteoporosisHelps with diabetes – utilize sugar
more effectively Decreases risk of mortalityHelps with sleep
WARM UPWARM UP
Should be 8 – 10 minutes long, at a lower intensity than actual exercise session
Prepares body for vigorous exerciseHelps reduce the risk of injuriesRaises body temp, heart rate, blood pressure
COOL DOWNCOOL DOWN
Should be at least 5 minutes long at a low intensity level
Gradually decrease body temperature, BP and HRHelps decrease risk of muscle soreness and injuryWhy do we discourage sitting in between sessions?

Frequency: the number of times per week one should exercise 3-5(7) x/week
Intensity: how hard one is working while exercising THR, RPE scale
Type: what kind of exercise…walking, biking etc.Time: duration of each exercise session 20-60 min
Target Heart Rate (THR)Target Heart Rate (THR)
Max HR Theoretically you can use 220-age 220 - age(22) = 198 (Max HR) 198 *.7 (70%) = 136 bpm 198 * .85 (85%) = 168 bpm
A stress test can more accurately determine a peak HR for us to take a % of.

Benefits of Strength Training
Avoid muscle loss Increase muscle mass
Reduce body fat Improve glucose metabolism
Strength Training – F.I.T.T principles Strength Training – F.I.T.T principles
Frequency: 2 – 3 x/week with rest days in between
Intensity: 15 repetitions (1-2 sets) Type: dumbbells, barbells, calisthenics,
machinesTime: no time limit
Rest 30-45 seconds between setsEach lift should be slow and controlled
Strength Training Principles
Strength Training Principles
Overload: to see gains you must stimulate the muscle to more than it is used to
Progression: Continue to work against a gradually increasing resistance in order to meet overload
Specificity: Any gains made are specific to the muscle groups and pattern performed
Always remember to BREATH during resistance training
FlexibilityFlexibility
“Range of Motion” around a joint As one ages the tissues around joints tend to
thicken and become rigid. Stretching improves posture, circulation, and
balance. It soothes pain in joints; helps relieve lower back pain and prevent injuries.
Flexibility F.I.T.T.Flexibility F.I.T.T. Frequency: after each exercise session
(most days) Intensity: hold each stretch to a feeling of
mild discomfort. DO NOT push through pain Type: Static stretching is recommended.
(reach and hold) never bounce to stretch Time: hold each stretch 15-30 seconds 2-3 x/each
If, for some reason you have not been able to
exercise for 2 weeks . . .
If, for some reason you have not been able to
exercise for 2 weeks . . . Start back slowly at about ½ of the level that
you were at when you stopped Gradually increase your intensity over a 1-2
week period Remember to warm up and cool down
Don’t just jump right back into where you left off
Signs and Symptoms that you should slow down or
get help
Signs and Symptoms that you should slow down or
get help
Any chest discomfortSevere shortness of breathDizziness, lightheadedness
Severe muscle crampsRapid or very slow HR
Confusion, disorientationNauseous, vomiting
Excessive or unusual sweating
METsMETs
Measurement of energy expenditure.This gives us an idea of how much energy you are
producing while exercising or during an activity.
1 MET = the energy (oxygen) used by the body as you sit quietly, perhaps while talking on the phone or reading a book.
Check out your MET levels…
Check out your MET levels…
Compare what you are tolerating in class to what is on the handout.
Used in rehab to show progression Ave CR graduates with a 4-5 MET level
Restrictions included may be orthopedic limitations not just cardiovascular
