Recovery beyond rest - the key to adaption and performance.

Sports Performance Nutritionist Hannah Presswood explains why recovery goes beyond rest, and how nutrition underpins performance and adaptation.

Most athletes think they’re recovering well.

They take rest days and aim to get enough sleep. But despite this, many still feel fatigued, struggle to maintain consistency, or don’t see the improvements they expect at the rate they want.

That’s usually because recovery is being treated as passive — something that happens once training is done.

In reality, recovery depends on how well the body is supported during and after training. Without the right inputs, the body cannot fully repair, restore, or adapt. Rest is important, but it’s only part of the picture.

Recovery vs. Adaptation

It’s useful to make a distinction between recovery and adaptation, because they’re often lumped together but aren’t the same thing.

Recovery is the short-term process of getting back to a state where you can train again.

Adaptation is the longer-term process where fitness and performance actually improves.

You can feel recovered, but if your body hasn’t been properly supported, you won’t get the full benefit of the training.

Endurance training places a high demand on the body. It increases energy use, fluid loss, cell turnover, and the need for nutrients to repair and rebuild. If dietary intake doesn’t provide this, the body simply doesn’t have the resources to a) recover properly, and b) adapt to the training stimulus. Over time, this leads to fatigue, reduced performance, and an increased risk of illness or injury.

Total energy intake is the foundation of recovery and adaptation. Without enough overall energy, and at the right time, key processes such as glycogen restoration, muscle repair, immunity and hormone regulation are all affected. This is why increases in training load need to be matched with increases in energy intake, and why nutrition timing matters.

Within this, carbohydrate plays a central role. It is the primary fuel source for moderate- to high-intensity exercise, and it is essential for restoring glycogen stores between sessions. If carbohydrate intake is too low, athletes will over time notice a drop in training quality, difficulty backing up sessions, and an overall sense of fatigue. For athletes training regularly and towards a performance goal,

adequate carbohydrate intake is not optional — it underpins performance. For athletes training most days, this means including a meaningful source of carbohydrate in all meals, and prioritising intake around training.

Protein plays an important role in recovery, but its function is often misunderstood. It supports muscle repair and long-term adaptation rather than immediate recovery. Meeting daily protein needs is important, but in situations where athletes need to recover quickly between sessions, energy intake, carbohydrate, and hydration all have a greater impact.

Many athletes also rely on recovery strategies such as sauna, ice baths, compression, and massage. While these do provide some benefits, they are minor compared to the fundamentals. If energy intake, carbohydrate availability, and hydration are not in place, these strategies will have limited effect.

Ultimately, recovery is not something that can be left to chance. It requires consistently supporting the body with enough energy, carbohydrates, hydration, and the nutrients needed to support repair and adaptation.

When these are in place, recovery supports performance. When they are not, it becomes the limiting factor.
