If Compression is Therapy, Who is Managing the Dose?

In my last article, 'Sports Compression Became Fashion. Who is Advancing the Therapy?', I argued that sports compression has increasingly become defined by apparel rather than therapy.

Compression has become more accessible, more comfortable and more widely adopted. That is progress.

But if we accept that compression is an intervention rather than simply something we wear, another question follows.

What is the dose?

In almost every therapeutic environment, dose matters.

We would not assume that the same intervention, delivered in the same way, is appropriate for every individual, every objective and every circumstance.

Yet in sports compression, we often do exactly that.

Choose a size.

Choose a compression level.

Put it on.

The assumption is that the product will take care of the rest.

I think we need to ask a more fundamental question.

If compression is therapy, who is managing the dose?

Can one compression product really do everything?

Consider two athletes.

One is preparing for a training session.

The other has just completed a marathon.

Their bodies are experiencing different demands. Their objectives are different. The point at which compression is being used is different.

Why, then, would we automatically assume they require the same compression intervention?

During exercise, compression may be used to provide support while allowing unrestricted movement. During recovery, the objective changes.

Travel presents another set of circumstances.

So does rehabilitation.

Yet sports compression is frequently presented as though one product can move seamlessly between all of these situations and deliver an appropriate intervention every time.

Perhaps it can.

But we should not simply assume that it does.

If compression is intended to influence physiology, we need to understand not just whether somebody is wearing compression, but what compression is being delivered, to whom, for what purpose and when.

That is where the concept of compression dose becomes important.

What is compression dose?

Compression dose is more than a pressure number printed on a label.

It is the level and distribution of pressure being applied in relation to the individual receiving it and the physiological objective we are trying to achieve.

That means considering:

• the level of pressure applied

• how that pressure is distributed

• the anatomical area being compressed

• the individual's anatomy

• the intended physiological objective

• whether compression is being used during exercise or recovery

• how long it is being worn

• construction and fit

These variables matter because compression is not acting on a standardised object.

It is acting on a human body.

And human bodies are different.

Compression dose is not just a number.

It is tempting to reduce compression to a single figure.

18 mmHg.

25 mmHg.

30 mmHg.

But a pressure specification does not tell us the whole story.

Pressure can vary according to anatomical location, product geometry, stretch, fit and movement.

Two athletes wearing the same nominal size may not necessarily experience the same compression.

Their anatomy is different.

Their body dimensions are different.

Their movement may be different.

And their reason for wearing compression may be different.

This is why I believe the industry needs to think more broadly about what constitutes a compression dose.

Pressure + distribution + anatomy + purpose + duration.

Suddenly, compression becomes a much more individual intervention.

The right dose depends on the purpose.

This becomes particularly apparent when we consider the difference between activity and recovery.

During exercise, an athlete may be looking for support, comfort, proprioceptive feedback or potential physiological effects associated with compression.

Whatever the objective, the compression also needs to coexist with movement and the demands of the sport.

Recovery presents a different challenge.

The athlete is no longer performing the same task. The physiological objective has changed. The duration of use may change. The appropriate pressure may change.

This does not mean that one form of compression is universally better than another.

It means that the intervention should reflect the purpose.

The right compression during activity is not automatically the right compression during recovery.

And the right recovery intervention for one athlete is not automatically right for another.

If the dose matters, the individual matters.

This is where personalisation stops being a product feature and becomes part of the therapeutic logic.

A standard product is necessarily designed around a population, size range or assumed body shape.

Personalised compression starts somewhere else.

With the person.

What is their anatomy?

What are we trying to achieve?

What area are we compressing?

What pressure is appropriate?

How should that pressure be distributed?

How long is the intervention required?

These are very different questions from:

What size do you wear?

And they lead us towards a different model of compression.

Instead of asking:

Which compression product should I buy?

We can begin asking:

What compression dose is appropriate for this individual and this objective?

The evidence tells us to ask better questions.

The scientific literature does not support the idea that all compression produces the same outcome in every circumstance.

Research into sports compression varies considerably according to pressure, product design, body area, duration, application and the individuals being studied.

That complexity is sometimes treated as a weakness.

I think it tells us something important.

Perhaps the question has been too broad.

Instead of simply asking:

Does compression work?

We should ask:

What compression?

For whom?

At what dose?

For what purpose?

For how long?

Those are harder questions.

But they are also much more useful ones.

From compression products to compression therapy.

None of this means that sports compression needs to become complicated for the athlete.

Quite the opposite.

The complexity should sit behind the intervention.

Assessment, measurement, product design and manufacturing technology should do the difficult work so that the athlete does not have to.

The athlete should simply receive compression appropriate to them and what they are trying to achieve.

That, to me, is where sports compression needs to go next.

The industry has become very good at manufacturing compression products.

The next challenge is learning how to manage compression as an intervention.

Because if compression is therapy, the dose matters.

And if the dose matters, we need to define it rather than assume it.

But defining the appropriate dose is only half of the problem.

Because there is another question the compression industry rarely asks:

What happens to that dose over time?

A compression product can deliver a particular pressure when it is first fitted.

But athletes don't use compression in laboratories.

They move in it.

They sweat in it.

They stretch it.

They wash it.

And they use it again and again.

So if pressure is part of the intervention, there is one more question we need to answer:

Does the dose last?

In Part 3, I’ll explore why dose retention may be one of the most overlooked questions in sports compression and why delivering the right pressure on day one is not enough.
