Summary

This study looks at how different meals before exercise affect amino acid levels in adults with phenylketonuria (PKU). Ten participants will try water, carbohydrates, or protein before doing aerobic and resistance exercises. Researchers will measure changes in blood amino acids to see which pre-exercise meal is best for metabolic control.

What this could mean

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

Active substance: carbohydrates and protein supplements, water
What this could lead to: If successful, this could help determine the best pre-exercise meal for people with PKU to maintain stable amino acid levels during exercise.
What could go wrong: This is a very small early study with only 10 participants, so results may not apply to all PKU patients. It is observational and does not test a new treatment.
