6. Conclusions
The addition of supplemental protein and carbohydrates to the diet of career firefighters throughout a three-week period improves occupational performance in specific areas of high-intensity activities. Furthermore, the addition of creatine within the protein and carbohydrate supplementation leads to greater improvements in specific tests when compared to protein and carbohydrates alone. These findings provide preliminary evidence supporting the benefits of targeted dietary strategies for occupational performance benefits in firefighters.
