Study Summary

Phenylketonuria (PKU), an inherited genetic disorder, can cause irreversible brain damage, declined executive function, and autistic tendencies unless a phenylalanine (Phe) restricted diet is consistently maintained throughout life. Promoting anabolism, the uptake of free amino acids from the extracellular space, is a key component to maintaining plasma phenylalanine concentrations within treatment range among patients with PKU. Exercise promotes muscle protein synthesis and anabolism, but the effect on blood phenylalanine concentrations in patients with PKU has not been reported. Our objective is to assess the impact of an acute bout of moderate intensity exercise on protein oxidation and plasma amino acid concentrations, as a potential adjunctive therapy for patients with PKU. The investigators hypothesize that moderate intensity exercise decreases amino acid oxidation, increases muscle protein synthesis, and promotes tissue uptake of essential amino acids, thereby lowering plasma phenylalanine concentrations in patients with Phenylketonuria.

Primary Outcome

Compare the final blood sample for phenylalanine concentration from each arm of the study.
