Beef-Protein Ready-to-Eat Meals to Support Firefighter Recovery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Healthy adult firefighters participate in a randomized, double-blind crossover trial to see if beef-based protein meals improve recovery, physical performance, and cognitive function after strenuous simulated firefighting tasks compared with plant-based protein meals. Each participant tries both meal types in separate periods with a 14–21 day washout. The meals are matched for energy and macronutrients, so any differences may relate to protein source. Outcomes include markers of muscle damage, physiological stress, soreness, and occupational performance. The study takes place at Fort Worth and Huntsville sites under the lead sponsorship of Sam Houston State University.
