Summary

Researchers are testing whether eating pork-based protein meals before and after simulated firefighting tasks helps the body recover. The study enrolls 20 healthy adult firefighters who complete three meal conditions: pork protein, plant protein, and a carbohydrate-focused control. Each firefighter tries all three meals in random order, with 14 to 21 days between sessions. The team measures muscle damage markers, stress hormones, soreness, and performance on firefighting tasks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Pork-based protein ready-to-eat meals
What this could lead to
If pork protein helps, it could offer firefighters a simple meal strategy to recover faster after the physical strain of the job.
What could go wrong
This is a small study of 20 firefighters, so results may not apply to all people or all types of exercise. Diet studies also struggle to separate the protein itself from other differences in the meals.

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.
