Week 2 Flashcards
What is aerobic exercise
low power outputs that help improve cardiorespiratory health
- running/cycling/swimming
FITT acronym
F - frequency
I - intensity
T - time
T - type
Frequency principle
5 days a week of moderate
3 days a week of vigorous
Intensity principle
most important factor in determining training effect
- % MHR
- HRR
- %VO2max
- RPE
- talk-test method
% Maximal Heart Rate (%MHR)
60-90% of MHR
MHR = 220 - age
Heart Rate Reserve method (HRR)
50-85% of HRR
HHR = 220 - age - RHR
% of VO2max
VO2max = max amount of oxygen delivered to muscles
HR used b/c has a linear relationship with VO2max
Metabolic Equivalents
sitting at rest, the rate of energy expended = 3.5 METs
Rate of percived exertion (RPE)
heart rate divided by 10 and ranked on a scale
- highest = 20, lowest = 6
Talk test
you should be able to carry a conversation but not sing, if you cant talk the intensity is too high
Time principle
moderate exercise >150 mins a week
vigorous exercise >75 mins a week
Type principle
large muscle groups required, small muscle groups fatigue before CV system is stressed
Warm up benefits
- prevents muscle acidity too early in workout
- lessens chance of inadequate blood flow to heart
- improved cardiorespiratory performance
RAMP
R - RAISE blood flow/temp
A/M - ACTIVATE muscles through MOBILIZATION of muscles
P - POTENTIATE specific movements/loads/intensities
Cool down
- maintains venous return to the heart/brain
- maintains a large blood supply to the muscle
- hastens removal of lactate
- reduces [conc] of exercise hormones
Flexibility defenition
absolute ROM at a given joint
common training errors
- not individualizing program
- not warming up effectively
- not recovering or cooling down
- too much too soon
Mobility definition
the ability to move or be moved freely and easily
Static flexibility
ROM about a joint during passive movement
Dynamic flexibility
available ROM during active movements
development of flexability
- 4+ stretches per joint 2/3 days a week after exercise
- slowly elongate the muscle & staticly hold
- 2 to 4 reps, hold 15-60 seconds
static stretching
hold for 20 sec, lessens the sensitivity of receptors
passive static stretching
involves external force like gravity or a partner
active static stretching
moving limbs into position by contracting the agonist muscle with no external force
