Blood Flow Restriction Training: Understanding the Safety, Mechanisms, and Efficacy, 2nd Edition: Summary 8
14. All of the following are precautions or contra- indications for BFRT, except: a. Pregnancy b. Sickle cell anemia c. Acidosis d. General weakness 15. What types of BFRT can be used to build muscle strength and muscle mass? a. BFRT-AE b. I-BFRT c. Passive BFRT d. All of the above 16. The ACSM suggests that: a. 40% VO2 max corresponds to 70% HR max b. 30% VO2 max corresponds to 70% HR max c. 80% VO2 max corresponds to 85% HR max d. 85% VO2 max corresponds to 100% HR max a. Increased muscle mass and strength b. Faster recovery c. Decreased pain d. All of the above 18. Why do you need to know the patient's limb occlusion pressure (LOP)? a. It is used for dosing the treatment, as it relates to pressure used in the cuff b. We obtain LOP using an MRI machine c. You do not need to LOP d. Most protocols use 60-80% of LOP for upper body exercise and 30-50% of LOP for lower body exercises 19. What is TRUE regarding different brands or products of BFRT devices? a. Some brands have narrow bands and others have wider bands b. Some brands have a single bladder c. Some brands have built-in mechanisms to optimize pressure in the cuff d. All of the above 20. What is TRUE for patients who have been immobilized or have been inactive? a. Disuse of muscles leads to atrophy and loss of muscle strength at about 12% per week b. Limb immobilization for 3 days can lead to 44- 47% atrophy 17. What is a benefit of BFRT? c. Atrophy can be reversed by isometric exercises d. Dirks showed no decline in cross-sectional area (CSA) with 1 week of bed rest
21. What is NOT true about studies regarding BFRT with aerobic exercises? a. Park showed improvement of VO2 max with a walking program b. All studies used around 40% of resting heart rate for intensity c. Studies have been done with cycling and walking d. Many studies showed improvement in aerobic capacity, but results varied 22. What is TRUE about benefits of BFRT? a. This exercise therapy can increase muscle mass, muscle strength, and balance b. Some studies suggest the possibility of weight loss and improved bone health c. Participants in studies had either improved aerobic capacity or improved strength d. Pain relief with BFRT has not been studied 23. What is true about high and low pressure BFRT? a. Lixandrão showed that with low resistance levels we should use high-pressure BFRT to increase strength b. Both low and high pressure have similar results c. All BFRT has been studied with low pressure d. Low-pressure BFRT has been shown to reduce pain better than high-pressure BFRT 24. What is TRUE about the amount of pressure used for BFRT? a. Studies have used the same levels of pressure b. Most commonly in recent studies we have seen 30-50% LOP pressure for the upper body and 60-80% LOP in the lower body c. The amount of pressure does not affect the results of BFRT d. All of the above 25. What is true about the use of BFRT? a. BFRT is safe when done with individual parameters in the absence of contraindications b. BFRT can be effective for the trained and untrained patient c. BFRT can help to improve muscle strength, reduce atrophy, and improve aerobic conditioning d. All of the above
