Today's article review was selected after a conversation with a colleague around the use of passive BFR to attenuate loss with injury or limb immobilisation. This is also very relevant with my recent knee surgery and I've used Blood Flow Restriction heavily to assist my recovery.
The article I review is called:
Preventionof disusemuscular weaknessby restrictionof bloodflow.
The aim of the present study was to compare the effects of periodic restrictionof bloodflowto lower extremities with those of isometric exercise on disusemuscularatrophy and weaknessinduced by immobilization and unloading.
The left ankle of each of 15 healthy males was immobilized for 2 wk using cast, and subjects were instructed to walk using crutches with non-weight bearing during this period. Subjects were divided into three groups: a restrictionof bloodflow(RBF) group (application of external compressive force of 200 mm Hg for 5 min followed by 3 min of rest, repeated five times in a single session, two sessions per day for 14 d); an isometric training (IMT) group (20 "exercises" of 5-s isometric contraction of the knee extensor, flexor, and ankle plantar flexor muscles followed by rest, twice a day, daily for 2 wk); and a control(CON) group (no intervention). We measured changes in musclestrength, thigh/leg circumferences, and serum growth hormone levels.
