Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Nonexercised rested day
Athlete will not exercise on trial day.
Endurance exercise
On the trial day before commencing the indicator amino acid oxidation metabolic trial, participants will either rest, perform a 10km run on a treadmill, or perform a 20km run on a treadmill.
Recovery from 10KM run
Athlete will run 10km on trial day.
Endurance exercise
On the trial day before commencing the indicator amino acid oxidation metabolic trial, participants will either rest, perform a 10km run on a treadmill, or perform a 20km run on a treadmill.
Recovery from 20KM run
Athlete will run 20km on trial day.
Endurance exercise

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Participants who have a self-reported 5-km run time of ≤23 min
* Participants who are categorized as at least "very good" based on a study by Shvartz \& Reibold (Aviat Space Environ Med. 1990 Jan;61(1):3-11), in which VO2peak is used as an index. (i.e. the participants whose VO2peak is ≥57 ml/kg/min (18-24 y), ≥54 ml/kg/min (25-29 y), ≥52 ml/kg/min (30-34 y), ≥49 ml/kg/min (35-39 y)
* Ability to complete the 16-km familiarization run on Session 2
* Aged 18-40 years old
Exclusion Criteria
* Female: hormonal fluctuations associated with the menstrual cycle have been reported to alter protein metabolism during exercise and may influence specific amino acid requirements at rest; as such, the present study will test the effect of endurance exercise on protein requirements in males only to ensure a stable hormonal environment and to increase the homogeneity of the physiological response. (NOTE: we plan to test females in a future trial based off of the results obtained herein)
* Inability to adhere to any of the protocol guidelines (i.e. alcohol, caffeine consumption)
* Regular tobacco use
* Illicit drug use (e.g. growth hormone, testosterone, etc.)
