What does BFR stand for?

Top 10 Meanings of BFR

1. Blood Flow Restriction

Blood Flow Restriction (BFR), also known as occlusion training or vascular occlusion, is a fitness and rehabilitation technique that involves applying a pneumatic tourniquet or specialized wraps to partially restrict blood flow to working muscles during exercise or physical therapy sessions.

Mechanism:

BFR involves wrapping a cuff or band around the proximal portion of a limb, such as the upper arm or thigh, to reduce venous return while allowing arterial inflow, creating a temporary restriction in blood flow to the muscles distal to the occlusion site.

Benefits:

• Muscle Hypertrophy: BFR training can stimulate muscle growth and hypertrophy by inducing metabolic stress, muscle fatigue, and cellular swelling, leading to increased muscle protein synthesis and satellite cell activation.
• Strength Gains: BFR exercises performed with light loads can produce significant strength gains and improvements in muscle endurance, motor unit recruitment, and neuromuscular adaptations, despite using lower resistance compared to traditional resistance training.
