blood flow restriction Flashcards
1
Q
origin of BFR
A
japan
2
Q
first use of bfr
A
self-experimentation following a leg fracture
low impact exercise to help rehab
3
Q
types of BFR
A
electronically controlled pneumatic cuffs
- elastic bands
4
Q
conditions to bfr
A
- blocks venous blood flow from returning to the heart w/o occluding arterial flow
- 40% of limb occlusion is desired
- up to 80%
- should be placed at most proximal part of the limb regardless of muscle group desired
5
Q
why use bfr
A
- allows low intensity exercise to mimic high intensity
- reap similar benefits form lighter workouts
- appropriate for all age groups
6
Q
why use bfr for resistance training specifically
A
- form of tx for musculoskeletal disorders
- ## in normal circumstances 60-80% of 1rm is needed to see benefits
7
Q
what % of 1RM is reduced with BFR
A
20-30%
8
Q
physiological outcomes of BFR
A
- lactate build up
-inc metabolic stress
-higher heart rate response
9
Q
components of inc metabolic stress
A
- cell swelling
- inc hormone rel
- anabolic signalling for muscle growth
10
Q
when is bfr most beneficial
A
low-intensity-
11
Q
ideal for what kind of oa
A
adults who are reconditioned, suffering from chronic diseases, extremely frail
12
Q
2 diseases commonly experienced by OA
