Compression therapy has been used for decades in healthcare, rehabilitation, and sport. From managing swelling after injury to supporting recovery between training sessions, compression garments are now commonly used by healthcare professionals, athletes, runners, cyclists, and active individuals alike.

Despite their popularity, many people are unsure how compression therapy actually works, who it is for, and whether it genuinely provides any benefit.

This article explains the science behind compression therapy, when it may be used, and how personalised compression technologies are helping improve outcomes for both patients and athletes.

What Is Compression Therapy?

Compression therapy involves applying controlled pressure to a part of the body using specially designed garments such as socks, sleeves, tights, or other compression wear.

The aim is to support circulation, assist fluid movement, and improve comfort during recovery, rehabilitation, or physical activity.

Compression garments are used in a variety of settings, including:

- Sports and athletic recovery
- Physiotherapy and rehabilitation
- Swelling and oedema management
- Post-operative recovery
- Long periods of standing or sitting
- Certain circulatory conditions

The amount of compression applied can vary significantly depending on the intended purpose and the needs of the individual.

How Does Compression Therapy Work?

To understand compression therapy, it helps to understand how blood and fluid move around the body.

Your circulatory system relies on blood being pumped away from the heart through arteries and then returned through veins.

At the same time, your lymphatic system helps remove excess fluid, proteins, and waste products from tissues.

When injury, surgery, inactivity, or prolonged exercise occurs, fluid can accumulate within tissues. This can contribute to:

- Swelling
- Feelings of heaviness
- Stiffness
- Discomfort/Pain
- Reduced movement

Compression garments apply external pressure to the tissues, helping support the movement of blood and fluid through these systems.

The result can be improved fluid management and greater comfort during movement and recovery.

The Science Behind Compression Therapy

Compression therapy is thought to work through several mechanisms.

Supporting Venous Return

Veins in the legs must work against gravity to return blood back towards the heart.

External compression may help support this process by reducing the diameter of superficial veins and encouraging more efficient blood flow.

This can be particularly useful during periods of reduced movement or recovery.

The appropriate amount of compression applied correctly to the legs can significantly increase blood flow back to the heart (venous transit time) and reduce pooling.

This optimises circulation and tissue perfusion, supporting oxygen delivery to working and recovering muscles, reducing swelling, and promoting recovery.

Assisting Lymphatic Drainage

The lymphatic system helps remove excess fluid from tissues.

When swelling develops, the lymphatic system can become overloaded.

Compression can help facilitate fluid movement and support the body's natural drainage processes.

Managing Swelling

One of the most widely recognised uses of compression therapy is oedema management.

By helping control fluid accumulation within tissues, compression may reduce swelling and the associated discomfort that often accompanies it.

Improving Comfort During Activity

Many athletes report reduced feelings of heaviness, fatigue, or muscle soreness when using compression garments during training or recovery.

While individual experiences vary, improved comfort is one reason compression remains widely used across multiple sports.

Compression Therapy in Sport

Compression garments have become increasingly common in endurance sports and athletic performance environments.

Runners, cyclists, triathletes, footballers, rugby players, and gym users frequently incorporate compression into their training and recovery routines.

Common reasons include:

- Recovery between training sessions
- Management of training load
- Reduction of post-exercise swelling
- Support during rehabilitation from injury
- Comfort during prolonged exercise

Compression garments are now regularly seen across elite sport, including professional cycling, athletics, football, and endurance events.

Can Compression Therapy Improve Performance?

This is one of the most common questions athletes ask.

Current research suggests that compression garments are unlikely to dramatically improve athletic performance on their own.

However, compression may provide indirect benefits by supporting comfort, recovery, and training consistency.

For many athletes, the greatest value comes from maintaining training quality and reducing interruptions caused by soreness, swelling, or minor injury setbacks.

This is particularly relevant for runners completing high training volumes or preparing for races.

Active Compression vs Recovery Compression

Not all compression garments serve the same purpose.

Active compression is designed to provide support and comfort during exercise, while recovery compression focuses on managing swelling, supporting circulation and aiding recovery after training, competition or rehabilitation.

Because the pressure requirements and intended outcomes differ, a garment designed for activity may not deliver the same benefits during recovery, and vice versa.

Compression Therapy for Runners

Running places repeated stress through the muscles, tendons, joints, and soft tissues of the lower limbs.

As a result, runners often experience:

- Delayed Onset Muscle Soreness (DOMS) following hard training sessions or races

- Calf fatigue

- Lower leg soreness

- Swelling following long runs

- Feelings of heavy legs during high-volume training

Compression garments are frequently used alongside strength training, recovery strategies, and physiotherapy to help manage these demands.

At the White House Clinic, compression therapy may be incorporated into broader rehabilitation programmes for runners recovering from injury or returning to training following a setback.

Why Fit Matters

Not all compression garments deliver the same results.

The effectiveness of compression therapy depends heavily on achieving the intended level of pressure across the correct areas of the body.

Traditional compression garments are generally manufactured using standard sizing systems and are unable to guarantee the pressure being delivered to the wearer.

The challenge is that no two people have exactly the same limb shape.

A garment that fits one person perfectly may provide too little compression or excessive compression for another. Ultimately no one knows what pressure they’re getting which makes it difficult to know whether the intended therapeutic or recovery pressure is actually being achieved.

This can affect comfort, effectiveness, and overall outcomes.

The Move Towards Personalised Compression

Advances in technology are helping address some of the limitations of traditional compression garments.

Personalised compression systems use digital scanning technology to capture the shape and dimensions of an individual's limb before a garment is manufactured.

This allows compression to be tailored more accurately and consistently to the person wearing it.

At the White House Clinic, we’ve partnered with ISOBAR, whose ISOFIT® video scanning technology enables precision-engineered compression garments to be produced according to an individual's unique anatomy and therapy needs. In addition, ISOBAR is manufactured using advanced NeoMeshTM fabric technology, engineered to maintain consistent compression performance over repeated wear and washing. This helps ensure that the intended pressure profile is retained throughout the life of the garment, supporting long-term reliability and effectiveness.

The result is a more personalised approach to compression therapy, reducing the variability associated with generic compression and improving outcomes.

Personalised Compression Therapy as Part of Rehabilitation

Compression therapy should not be viewed as a standalone solution.

Whether the goal is injury recovery, swelling management, post-operative rehabilitation, or returning to sport, compression works best when integrated into a structured treatment plan.

This may include:

- Physiotherapy assessment
- Exercise rehabilitation
- Strength and conditioning
- Load management
- Return-to-sport planning
- Recovery strategies

Compression is simply one tool that can support the wider rehabilitation process.

Is Compression Therapy Right for You?

The suitability of compression therapy depends on your goals, symptoms, medical history, and activity levels.

Athletes may use compression to support recovery and training consistency, while patients recovering from injury or surgery may benefit from compression as part of a wider rehabilitation programme.

A physiotherapist can help determine whether compression therapy is appropriate and advise on the most suitable approach for your needs.
