Why Logging Matters Most When You Are Injured

Written By Sam Leslie, September 2026

The injury and rehabilitation period is when your data is worth the most. What you log now shapes how quickly you recover, how safely you return and how likely you are to break down again.

Injury changes your load. It does not remove it.

Rehab, cross training, modified training, pain disrupted sleep and the stress of sitting out all place demand on your body and nervous system. If you stop logging then none of it is seen. Your coach cannot tell three weeks of solid rehab from three weeks on the couch, and those athletes need very different return plans.

The return phase is where risk peaks. Previous injury is one of the strongest predictors of the next one (Hägglund et al., 2006), and subsequent injuries often occur at the same site soon after return (Hamilton et al., 2011). Much of that risk comes from a load spike after a period of unmeasured detraining (Blanch and Gabbett, 2016). Logging throughout your injury rehab is how you manage it.

Athletes often under report pain for fear it will slow their return, but it is actually the reverse. Athletes who kept training while actively monitoring their pain levels with their physio did better than those who rested completely (Silbernagel et al., 2007). The key signal is the next-morning response. If pain settles within 24 hours, the tissue tolerated the load. If it stays up or climbs, it did not. You only see that pattern if you report or self analyse daily.

Daily wellness. Sleep, recovery, stress, mood, health and physical perception. Being injured affects all of them, and each one influences healing and guides how fast you can bounce back.

Niggle status. Add a log from the home page by clicking on the + sign. Go to Niggle and record the severity and impact on training.

Every rehab session. Log your Session Type (cross training, modified training, bike, pool, upper body work, core, anti-gravity running, walking or rehabilitation). It is all important and part of training.

Record the duration and RPE. A 40 minute rehab block at RPE 6 is real training load and will be the foundation for your return to sport.

Notes. What aggravated it, what eased it, how it felt the next morning and what your physio changed.

Next day check in. Log your injury and your training status when completing your daily check in. This will give more relevance to your Peak score.

The PEAK^ philosophy is health first, athlete second. When you keep logging, your Peak score continues to reflect how you are coping, your wellness and niggle data keep building your individual risk profile, and your support team can see rehab load build week by week. With PEAK^, your return is measured against your own baseline, not guesswork.

PEAK^ also applies a Density modifier, a small correction based on how many days you have trained in the past week. When injury limits you to fewer sessions, it stops a single workout being flagged as a false overload, then switches off as your training frequency returns to normal. This gives you a realistic view of your Load Balance.

It also matters psychologically. Fear of reinjury and low confidence are linked to poorer return-to-sport outcomes (Ardern et al., 2013). Watching pain settle and load build gives you evidence that you are ready.

Treat logging as part of your rehab. Complete your wellness check each morning, log each session straight after it and add a note when something changes. Go with your first impression. A pain score of 4 is not a failure. It is information. Downplaying symptoms to look ready is the quickest way back onto the injury list.

Injury does not pause your data. It makes it more important. Consistent logging captures the load, symptoms and wellbeing that determine how safely you return, and closes the gap between rehab and performance when re-injury risk is highest. The athletes who return best are not the ones who rested longest. They are the ones who had a measured rehabilitation on their way back.
