Blood flow restriction training (BFRT) is an innovative technique that can lead to greater gains in strength and muscle mass by creating a more effective workout.

BFRT enables you to achieve similar results as traditional strength training methods while using significantly lighter weights. It’s beneficial for individuals who may be recovering from an injury or have limited access to heavy weights. By using BFRT, you can achieve significant gains in strength and muscle mass with weights as light as 20-30% of your typical one-rep maximum weight. For example, if you traditionally bicep curl with a 30-lb. dumbbell, you can achieve the same effect with BFRT using only 10 lbs.

At Parkway Physiotherapy in Happy Valley, we offer blood flow restriction training as part of our rehabilitation and fitness programs. Our trained professionals can help you safely and effectively incorporate BFRT into your exercise routine to achieve your goals.

How does BFRT work?

Also known as occlusion training, BFRT involves restricting blood flow to a muscle while exercising using a specialized cuff or wrap. This can lead to a number of physiological changes: increased muscle protein synthesis, growth hormone release and muscle cell swelling.

This technique creates a hypoxic environment in the muscles that stimulates the release of growth hormones and the insulin-like growth factorIGF-1, both crucial to muscle growth and repair. In addition, BFRT has been shown to increase the production of nitric oxide, which improves blood flow and enhances nutrient delivery to the muscles.

BFRT also creates metabolic stress in the muscles, which triggers a range of adaptations that enhance muscle growth and strength. Metabolic stress is created by the accumulation of metabolic by-products, such as lactate and hydrogen ions, which stimulate the release of anabolic hormones and activate muscle protein synthesis. BFRT also creates cellular swelling, which has been shown to enhance muscle protein synthesis and reduce muscle damage.

How can BFRT help me?

Speed Up Injury Recovery

BFRT can help speed rehabilitation after an injury by stimulating muscle growth and improving overall function without putting too much strain on the injured tissue. This can help accelerate the healing process and get you back to your normal activities more quickly.

Help Post-Surgery Recovery

BFRT accelerates post-surgery recovery. Studies show reduced muscle atrophy, increased muscle strength and better overall function in patients recovering from knee surgery, for instance, as well as reduced pain and swelling.

Manage Chronic Conditions and Diseases

BFRT can also be beneficial to those with chronic conditions such as knee osteoarthritis or rheumatoid arthritis. By enabling greater stimulus with lighter loads, BFRT can help improve overall quality of life by delivering greater muscle strength and function to individuals with these conditions.

Build Muscle Hypertrophy and Strength

While BFRT is most commonly used in rehabilitation settings, it is also gaining popularity in the fitness industry as a way to enhance muscle growth and strength gains. Incorporating BFRT into your training routine can help you achieve your fitness goals more efficiently and effectively.

Help Prevent Injuries Due to Muscle Weakness

BFRT helps with injury prevention by addressing muscle weakness through greater training stimulus with lighter loads. Overall, BFRT can be a valuable tool in rehabilitation and therapy.


In summary, Blood Flow Restriction Training (BFRT) is a promising technique that has been shown to offer several benefits. It can be used in a variety of settings, including exercise, rehabilitation, and strength training.

When used correctly, BFRT can help you achieve your fitness goals more efficiently. It can improve muscle strength and size, increase endurance, and enhance your overall physical performance.

Moreover, BFRT can be a useful tool for rehabilitation purposes, helping you recover from injuries faster and with less pain. It can also be used to prevent muscle loss during periods of inactivity, such as after surgery or during bed rest.

While BFRT is a relatively new technique, research has shown that it is safe and effective when used appropriately. However, it is important to seek guidance from a qualified professional before attempting BFRT on your own.

If you are looking for a way to improve your fitness or rehabilitation outcomes, BFRT may be worth considering. With proper guidance and application, it can offer a range of benefits that can help you reach your goals faster and more effectively.
