proper blood flow, control of blood pressure
comprises the parameters for the interventions for patients and clients
FITT Principle
Recommended Warm Up
5-10 min of light-to-moderate intensity cardiorespiratory and muscular endurance activities
transitional phase that allows the body to adjust to the changing physiologic, biomechanical, and bioenergetic demand
Warm up
T/F: A static flexibility exercises is superior to dynamic, cardiorespiratory endurance exercise warm-up
False. A dynamic, cardiorespiratory endurance exercise warm-up is superior to static flexibility exercises
Recommended duration for conditioning
20-60 min of aerobic, resistance, neuromotor, and/or sports activities
Recommended duration and exercise for cool-down
5-10 min of light-to-moderate intensity cardiorespiratory and muscular endurance activities
Purpose of the cooldown
to allow for a gradual recovery of heart rate (HR) and blood pressure (BP) and removal of metabolic end products from the muscles used during the more intense exercise conditioning phase.
Prevent pooling of the blood in the extremities by:
continuing to use the muscles to maintain venous return.
Prevent fainting by:
increasing the return of blood to the heart and brain as cardiac output and venous return decreases.
What happens if the patient immediately engages in endurance properly without performing warm-up?
Sudden rise/increase of the heart rate of vital signs = not good for the patients as it is difficult to control
What happens when warm-up is done prior to endurance proper?
Heart rate or vital signs will gradually increase the intensity up until the grey area is reached
At least 10 min of stretching exercises performed
after the warm-up or cool-down phase
Stretching
Goal: to increase ROM in the major muscle/tendon groups according to individualized goals
Flexibility Exercises
This can be improved by engaging in flexibility exercises, especially when combined with resistance exercise
Postural Stability and Balance
T/F: More effective when muscle temperature is increased through warm-up exercises
True

Vigorous intensity endurance activities requiring minimal skill
Exercise recommended for adults with aquired skill (under training) like swimming and skating
Endurance activities requiring skill
Exercises recommended for adults with regular exercise (Basketball, soccer, hiking)
Recreational Sports
Design of a training program needs to consider the activities and muscle groups exercise based on the needs of the particular patient, based on known vocational and recreational activities
Law of Specificity of Conditioning
Determinants of Intensity/Parameters/Methods
Heart Rate Method
Oxygen Consumption
Target HR (THR) = [(HRmax/peak − HRrest) × % intensity
HRR Method
Target VO2R = [( VO2max/peak − VO2rest) × % intensity desired + VOrest
VO2R Method
Target HR = HRmax/peak × % intensity desired
HR Method
Target VO2 = VO2max/peak − % intensity
desired
VO2 Method
Target MET = [( VO2max/peak) / 3.5 mL · kg−1 · min −1] × % intensity desired
MET Method
The commonly accepted range of training heart rate is
70% to 85% of maximal heart rate or 50% to 85% of maximal oxygen consumption
How to compute using the Heart Rate Method

Formula
When using this method, the prescribed intensity should
be between 60% to 70% of the VO2max
● Equivalent to HRmax

Oxygen Consumption Method
HRmax = 220 – age
● 60-80% (HRmax) for normal individuals
● <60% (HRmax) for cardiac patients
Maximum Heart Rate
HRR = HRmax – HRrest
0-60% (HRR) for cardiac patients
