1.  What is the primary mechanism by which Blood Flow Restriction (BFR) training enhances muscle adaptation?
  1. Increased arterial blood flow
  2. Creation of a hypoxic environment
  3. High-load resistance training
  4. Reduced venous outflow without arterial restriction
2.  Which of the following is a key consideration for safe and effective BFR application?
  1. Using arbitrary high cuff pressures
  2. Avoiding pre-screening for cardiovascular conditions
  3. Cuff selection and pressure levels
  4. Applying the cuff distally on the limb
3.  BFR therapy promotes the activation of which type of muscle fibers?
  1. Type I (slow-twitch)
  2. Type II (fast-twitch)
  3. Both Type I and Type II equally
  4. Neither, it only affects muscle protein synthesis
4.  What is the recommended pressure range for effective BFR training?
  1. 10%-20% of arterial occlusion pressure
  2. 40%-80% of arterial occlusion pressure
  3. 90%-100% of arterial occlusion pressure
  4. A fixed pressure of 200 mmHg for all individuals
5.  Which of the following is NOT a primary area of safety concern identified in the literature regarding BFR training?
  1. Venous thromboembolism (VTE)
  2. Potentially excessive hemodynamic/cardiovascular responses
  3. Muscle damage
  4. Increased muscle hypertrophy
