Brief Summary

This study will be the first in the literature to evaluate the relationship between aerobic and resistance exercises, plasma amino acid levels, metabolic control of patients, and the metabolic response to exercise with different types of meals in patients with Phenylketonuria (PKU). In patients with phenylketonuria, the aim is to determine which pre-exercise dietary recommendations are more physiologically appropriate and ideal for achieving good metabolic control. In the literature, there are very few studies examining the effects of exercise on plasma amino acid levels and metabolic parameters in PKU patients.

Eligibility Criteria

Inclusion Criteria: * Be over 18 years old, * Having a classic FKU diagnosis, * Not being actively engaged in sports, * Not having any other existing diseases, * Not having an active infection, * Have a BMI in the range of 20-28 kg/m2 within the last 3 months, * Agreeing to consume test meals and provide blood samples for parameters that will evaluate plasma amino acid levels as part of the research * Being willing to participate in this study Exclusion Criteria: * Presence of a chronic disease accompanying FKU disease (endocrine, etc.) * The individual with FKU has mental retardation or is deemed unfit for work based on psychomotor assessment, * Recent weight loss, history of hospitalisation, a past infection, or a diagnosed illness * Use of drugs or alcohol that alter protein and energy metabolism (e.g., corticosteroids, etc.) * Pregnancy status * Smoking habits The considerations to be taken into account when planning the day/date of the test are as follows. * Having engaged in heavy exercise or sports within 24 hours before the application of test diets, * Being in the menstrual period for female patients.
