aging and blow flow + video Flashcards
BFR block venous/arterial blood flow from returning to the heart without occluding venous/arterial flow
venous, arterial
how munch % of limb occlusion pressure is desired and up to % occlusion can be done - higher than this has been studied to have no greater benefits
40, 80
BFR should always be place at most proximal/distal part of the limb
proximal
why use BFR
- Allows low intensity exercise to mimic high intensity
- Reap similar benefits from much lighter workouts
- Appropriate for all age groups
using BFR reduce intensity to _% of 1 RM vs 60-80% 1RM in normal circumstances
20-30%
how can we achieve high-intensity benefits from BRF
- lactacte build-up, hypoxia factor activate due to low oxygen level in the muscle
- increased metabolic stress
- higher heart rate responses
BFR has been studied to be most beneficial at high/low intensity
low -> high create a counterintuitive effect
using BFR is ideal for who
for older adults who are deconditioned, suffering from chronic diseases, extremely frail etc…
what is sarcopenia
loss of skeletal muscle mass
Possible barriers to RT that can be overcome with BFR
Fear of injury
Need for equipment ($$)
The need for progressive overload
Intimidating gym settings
Transportation difficulties (no license, weather conditions etc.)
in video of 4 square step when does the time start and end
start: when patient foot make contact in the second square
end: when both feet return in inital square
when to stop 4 squares step test
if the patient loss balance, come in contact with the cane, cannot complete successfully
what were the 2 best predictors that a patient will be alive in 10 years (video 7)
- HR
- metabolism
when osteoblast need to built new bone which mineral does it need and where does it take it
calcium from the blood
which one between osteoclast or osteoblast break out the bone and release calcium into the bone
osteoclast
why is it important that osteoblast and osteoclast work together all the time
only osteoblast: bone will be too heavy
only osteoclast: not enough calcium in the bone -> result in osteoporosis
if blood calcium is too low, which one between osteoclast and osteoblast will work overtime
osteoclast to release calcium into the blood
if blood calcium is very high which one between osteoblast and osteoclast is more active
osteoblast
where did Anne taggard got her first hip fracture and second
1st in the stair while saying hello to a neighbor
2nd in her driveway where she slip
what did Anne taggard did to prevent to fall again
- take pills for osteoporosis
- take vitamin D3 and calcium supplement
- use a walker
- move slowly
- family remove stuff out of her way
