Summary

This trial will study how protein affects muscle and blood protein levels in adults who experience sleep loss, and if distributing protein evenly during recovery helps.

Who is the study for?
This trial is for healthy adults aged 18-39 with a BMI under 30, who exercise regularly and have stable weight without chronic illness or sleep disorders. Women must have normal menstrual cycles or be on low-dose hormonal contraceptives. Participants can't smoke, drink alcohol, caffeine, use supplements during the study, and must not be pregnant or breastfeeding.
What is being tested?
The study tests if different protein nutrition distributions during recovery from military-like sleep loss help muscle protein synthesis (MPS) and whole body protein balance (WBPB). It involves a week of normal sleep, four days of restricted sleep (~4h/night), followed by three days' recovery with controlled protein intake.
What are the potential side effects?
There may not be direct side effects from the nutritional intervention itself; however, participants might experience discomfort related to blood draws, muscle biopsies and dietary changes. Sleep deprivation could cause fatigue or mood changes.

Active Control
Group I: Protein Nutrition EvenExperimental Treatment1 Intervention
Volunteers will consume 1.6 g protein/kg/d as an even (\~0.4/0.4/0.4/0.4 g/kg) distribution across breakfast, lunch, dinner, and a snack.
Group II: Protein Nutrition SkewedActive Control1 Intervention
Volunteers will consume 1.6 g protein/kg/d as a skewed (\~0.11/0.27/1.15/0.07 g/kg) distribution across breakfast, lunch, dinner, and a snack.
