Blood Flow Restriction (BFR) training, a revolutionary approach in the world of sports and fitness, is gaining popularity among endurance athletes.

Originally used for rehabbing injuries or physical therapy, BFR involves the application of a cuff or band around the limbs to partially restrict blood flow during exercise.

Blood Flow Restriction Training, when integrated with endurance based exercises, offers a myriad of benefits, including increasing endurance, as supported by various studies.

How BFR Training Works to Improve Endurance

The principle behind BFR training is simple yet profound.

By restricting blood flow using a band or cuff, placed near the top of the arms or legs (as seen above), there is a significant reduction in the oxygen supply to the muscles.

This restriction of blood flow within the muscle simulates high-intensity training effects, even though the athlete engages in low to moderate-intensity workouts. Your muscles work harder even under the application of low-intensity activity.

So while you might just be running on a treadmill, the application of the bands will trick your muscles into thinking you’re running a marathon!

For endurance athletes, such as long-distance runners, cyclists, and swimmers, can incorporate BFR in their training routines by using it during their regular low-intensity exercises. For instance, a runner might use BFR bands while performing a light jog or during a recovery run.

10 BFR-based Endurance Exercises to Get You Right!

Here are some exercises that can be used with BFR bands can be used in various endurance training exercises:

1. BFR Walking or Light Jogging: Athletes can wear BFR bands on their upper thighs while walking or jogging at a low to moderate pace. This is particularly effective for warm-up routines or recovery days, as it increases muscle activation without excessive strain.
2. Cycling with BFR Bands: Cyclists can use BFR bands on their thighs while engaging in stationary or outdoor cycling at a moderate intensity. This helps to improve muscular endurance and strength in the lower body, crucial for long-distance cycling.
3. Swimming with BFR Bands: Although more challenging, swimmers can use BFR bands on their upper arms while swimming at a slow to moderate pace. This method increases the intensity of upper body workout without the need for faster or more strenuous swimming.
4. Rowing Machine with BFR Bands: Rowers can benefit from wearing BFR bands on their upper arms or thighs while using the rowing machine. This adds an extra level of resistance and enhances muscular endurance.
5. Elliptical Trainer with BFR Bands: Using BFR bands on the arms or legs while exercising on an elliptical trainer makes the workout more challenging, improving cardiovascular endurance and muscle strength.
6. Stair Climber with BFR Bands: Wearing BFR bands on the thighs while using a stair climber machine intensifies the workout, helping to build endurance in the leg muscles.
7. Yoga or Pilates with BFR Bands: Incorporating BFR bands during a yoga or Pilates session, especially in poses or exercises focusing on leg strength and endurance, can enhance muscle toning and endurance.
8. BFR while Weightlifting (Light): Performing low-intensity resistance exercises, like squats, lunges, or leg presses with BFR bands, can improve muscular endurance and strength, beneficial for endurance athletes.
9. Treadmill Incline Walking with BFR Bands: Walking on a treadmill at an incline with BFR bands on the thighs can simulate uphill training, improving leg strength and endurance.
10. Battle Ropes with BFR Bands: Athletes can wear BFR bands on their upper arms and legs while performing battle rope exercises at a moderate intensity.

Disclaimer: In all these exercises, it’s crucial to monitor the pressure of the BFR bands to ensure it is not too tight, causing discomfort or impeding circulation. The key is to maintain a balance where the bands are tight enough to restrict venous blood flow but not arterial inflow – aiming for a 7 out of 10 tightness, where 0 is not tight and 10 is too tight. This will help maximize the benefits of BFR training while minimizing risks.

How Effective is BFR Training for for Endurance Athletes? (Evidence)

The benefits of BFR training for endurance athletes are quite astonishing:

Aerobic BFR interventions have been shown to improve Vo2max of endurance athletes by up to 9.1%

–Journal of Strength and Conditioning Research

Vo2Max Gains

Vo2max is defined as ‘the maximum amount of oxygen a person can use during intense exercise.’

A higher VO2 max means a person can produce more energy.

A 9.1% increase in V̇o2max is quite substantial in the context of athletic performance. Even small improvements in V̇o2max can lead to significant gains in endurance events like running, cycling, swimming, and triathlons.

In competitive sports, where marginal gains can differentiate between winners and others, a 9.1% increase can provide a significant competitive advantage.

BFR Compared to HIIT

For comparison, High-Intensity Interval Training is known as one of the best ways to boost endurance and Vo2max.

Studies have shown that HIIT can improve V̇o2max by 6-15% over a period of weeks to months.

BFRT has shown to be nearly as effective as HIIT. If anything, BFR bands can be combined with HIIT in order to gain the best of both worlds.

Which Endurance Athletes Can Benefit from BFR Training?

Incorporating BFR into endurance training is easy.

The cuffs or bands should be applied to create a moderate level of pressure, sufficient to partially restrict blood flow but not cause discomfort or numbness. Athletes are advised to use BFR during low-intensity sessions or recovery periods, not during high-intensity workouts or competitions.

A typical session might involve 20-30 minutes of training with BFR bands, followed by a period of rest or normal training without restriction.

Here’s which types of endurance athletes can benefit from BFR training:

1. Long-Distance Runners
   • Enhances aerobic capacity.
   • Improves muscular endurance with low-intensity training.
2. Cyclists
   • Increases leg strength and stamina.
   • Boosts recovery during low-intensity rides.
