2nd test Flashcards
Pa vs exercise
both cna be used to improve or maintain physical fitness
PA: any movement that is carried out by muscles and that movement requires energy expenditure
ADLs, Gardening, Dancing
Ex: any planned, structured, rep and intentional movement
Aerobic v Resistance
strength reflects what
number of cross bridges that are effectively engaged, max amt of force in a single mm contraction
Cachexia vs sarcopenia
Cachexia: muscle wasting that occurs with an illness
Sarcopenia: natural occurance of decreased muscle mass due to aging
power
amount of work produced per unit time
force * Velocity
power OMs
TUG
5xSTS
6MWT - distance covered in certain amount of time (distance/ body wt)
peak cycling test
stair climb test
acute CV response to exercise
inc HR, SBP, CO, SV, RR
No change in O2 and DBP
Red flags for acute CV response
SBP fails to increase or drops below resting levels
DBP increases more than 10
BP downt return to norm in 8-10 min
frequency what is it
recommendations
number of session
3-5xwk aerobic
2x wk resistance
intensity what is it
recommendations
higher intensity requires longer recovery
HR linearly related to intensity
Time what is it
recommendations
duration total amount of time spent
type /mode
exercise specificity
aerobic and strength
progression
typically change in duration/frequency than intensity
how to know when to progress
no assessment of fatigue - can talk
BP and HR response to exercise
too much exercise may be as effective as too little
volume
summation of intensity and duration of an individual bout
physical activity guidelines
Moderate intensity: 150 - 300 mins a week
Vigorous intensity: 75- 150 min a week
Strength: >2xweekly
new exercise bouts do what
of any length contribute to the health benefits - 10 min minimum removed
Light METs 1.6 - 2.9
Ex: carrying 15lb child, Walking <2mph, bird watching, boating, canoeing 2-3.9mph
Mod METs 3-5.9
Ex: cycling <10mph, walking (descending stairs, pushing stroller), pushing w/c
vig >6 METs
Ex: running 6mph, climbing hill w/ 42lb, walking uphill at 5mph
L lung vs R lung lobes
L has 2
R has 3
