Blood Flow Restriction Training: Ultimate Guide

If you’re an athlete, you know that strength and conditioning are essential for success. But what if there was a way to improve your performance without spending hours in the gym? Then you should try blood flow restriction training or BFR training, for short.

In this article, I will discuss what BFR is, how it works, and the benefits of using it. I will also provide a guide on how to get started with BFR training. So whether you’re a professional athlete or just someone who wants to get in shape, read on to learn more about blood flow restriction training.

What is blood flow restriction training?

Blood flow restriction training (BFR) is a type of training that uses special equipment to restrict blood flow to the muscles being worked. This process is also known as “occlusion training” or “kaatsu training.” When you restrict blood flow, the muscles are forced to work harder to produce the same amount of force. This results in increased muscle strength and size.

You should perform blood flow restriction training as part of a multimodal approach, including other forms of exercise such as resistance training and aerobic training.

How does blood flow restriction training work?

While blood flow restriction training works in different ways, all methods involve disrupting blood flow to the limbs. So if you’re trying to build muscle, you need to do exercises that target the muscles you want to develop.

You can perform a blood flow restriction exercise using two the main ways to restrict blood flow:

Using a tourniquet: A tourniquet is a device used to restrict arterial blood flow. You use it by placing it around the limb you want to workout and tighten it until you achieve the desired level of restriction.

Wearing occlusive clothing/ gear: Occlusive clothing is special apparel that is also designed to restrict arterial blood flow. It is made of tight-fitting material that covers the limb being worked.

You need to place the tourniquet or the wraps around the entire upper or lower limb.

The pressure from the tourniquet or wraps will cause blood to pool in the limb, which is known as a process called venous occlusion. The level of restriction is typically expressed as a percentage of the maximum possible restriction. For example, if you are working at 50% restriction, your blood flow will be reduced by half.

When the muscles in the limb contract, they will squeeze the blood vessels and force the blood to flow back to the heart. The pressure level should be high enough to restrict blood flow but not so high that it cuts off circulation completely.

Restricting blood flow while training will result in muscle hypertrophy, which is an increase and the growth of muscle cells. The level of pressure will determine the intensity of the workout.

What are the benefits of blood flow restriction training?

There are many benefits to using BFR training, including:

Increased muscle strength and endurance: In one study, participants who used BFR training for 8 weeks resulted in an overall 11% improvement in both lower and upper body strength.

Increased muscle size: A study found that performing BFR training can stimulate skeletal muscle hypertrophy such as metabolic stress, skeletal muscle swelling, and muscle activation.

Improve aerobic capacity: BFR training can also help improve your aerobic capacity and muscle mass. In one study, participants who used BFR training for 12 weeks improved their VO₂ max (a measure of aerobic fitness) by 13%.

Reduced risk of injury: BFR training helps improve the function of your muscles and connective tissues.

The results of blood flow restriction training vary from person to person. However, you can expect to see some muscle growth and increased strength. You may also see improvements in your endurance and cardiovascular health.

Does blood flow restriction training work?

Yes, blood flow restriction training is an effective way to improve muscle strength and endurance. It can also help to increase muscle size.

As long as you do it properly, BFR training may improve sports performance and potentially assist individuals with chronic pain and other problems to develop muscle more quickly.

However, it is important to note that you should only perform BFR training under the supervision of a trained professional. This is because there is a risk of causing serious injury if the level of restriction is too high.

Is blood flow restriction training safe?

Blood flow restriction training is generally safe when performed under the supervision of a trained professional. However, there is a risk of causing serious injury if the level of restriction is too high.

It’s best to start with a lower level of pressure and gradually increase the intensity over time. If you are interested in trying BFR training, I recommend working with a certified trainer who has experience using this type of training. They will be able to help you safely and effectively use BFR to reach your fitness goals.

What are the risks of blood flow restriction training?

The main risk of blood flow restriction training is that it can cause serious injury if the level of restriction is too high.

How often should you do blood flow restriction training?

There is no one-size-fits-all answer to this question. Your blood flow restriction training will depend on your fitness goals and how your body responds to the training.

There are different types of occlusion training you can try out.

Low Load Occlusion Training

This type of training uses lighter weights and higher repetitions. The goal is to maintain muscle tension for a longer period.

You will need to lift roughly 20% of your weight for around 75 repetitions. This is divided into 3 to 4 sets, separated by a 30-second rest period.

I recommend performing it two to three times a week to get the most out of low-load occlusion training. Because your muscles don’t have time to recuperate, more frequent exercise is less effective. You may see results after ten weeks of training.

Low-Intensity Aerobic Exercise

This type of training uses low-intensity cardiovascular exercises, such as walking or jogging. The goal is to maintain a heart rate below 140 beats per minute. You should exercise for 30 to 60 minutes, 2 to 3 times a week. You will see improvements after around 6 weeks.

High-Intensity Resistance Exercise

This type of training uses high-intensity exercises, such as sprinting or lifting heavyweights. It’s ideal if you’re looking for strength gains.

You will need to lift roughly 80% of your weight for around 15 repetitions. This is divided into three sets, separated by a two-minute rest period. However, for this type of training, you will need professional guidance to prevent injuries.

Is blood flow restriction training painful?

No, blood flow restriction training is not painful. However, you may feel some discomfort during the exercises. This is because your muscles are working harder than they’re used to.

If you feel any pain during the exercises, you should stop immediately and consult with your trainer.

How to get started with blood flow restriction training

If you’re interested in trying BFR training, there are a few things you need to do first:

Find the right equipment: You’ll need a tourniquet or occlusive gear to restrict blood flow.

Determine the right level of restriction: The level of restriction should be high enough to cause venous occlusion but not so high that it cuts off circulation completely.

Start with low-intensity exercises: If you’re new to BFR training, begin with low exercises and gradually increase as you get more comfortable with the process.

What to expect with blood flow restriction training

Here are a few things you can expect from performing BFR training:

Discomfort

You may feel some discomfort during blood flow restriction training due to increased muscle tension. However, this discomfort should not be severe.

If you feel pain during the exercises, stop immediately and consult with your trainer.

Soreness

You may also experience some soreness after blood flow restriction training. This is because your muscles are working harder. To help reduce soreness, I recommend performing a light warm-up before the exercises and cooling down afterward.

Greater muscle growth

With blood flow restriction training, you can expect to see an increase in muscle size. This is because the training causes microtrauma to the muscles, which leads to muscle growth.

Improved performance

Over time, you will notice an improvement in your performance as your muscles become stronger and more efficient.

Wrap Up

Blood flow restriction training is a great way to increase muscle strength, size, and endurance. It can also help you achieve your fitness goals in a shorter amount of time.
