Recovery Protein Nutrition as a Countermeasure for Anabolic Resistance Following Sleep Loss

United States20 participantsStarted 2024-03-21

Plain-language summary

The current study will determine protein nutritional status (MPS and WBPB) in response to military-relevant sleep loss, and whether an even protein nutrition distribution during recovery optimally supports MPS and WBPB. Adults (n=20) will complete a 7d sleep satiated phase (\~7-9h target/d), a 4d military-relevant sleep restriction phase (\~4h /d), and a 3d recovery phase (\~7-9h target/d) in a randomized, parallel design. During recovery, volunteers will consume 1.6 g protein/kg/d as an even (\~0.4/0.4/0.4/0.4 g/kg) or skewed (\~0.11/0.27/1.15/0.07 g/kg) distribution. Sleep will be monitored throughout the study using wrist actigraphy and diaries. During each phase, integrated daily MPS will be estimated using ingested deuterium oxide, salivary and blood sampling, and muscle biopsies, while WBPB will be estimated using ingested 15-N alanine and urine collections. At the end of each phase, metabolic testing will be used to assess the effects of sleep loss on substrate utilization and include consuming a carbohydrate beverage, serial blood draws, indirect calorimetry, and steady-state aerobic exercise. The knowledge products derived from the proposed effort will be informative to next generation ration development and support military-specific recovery nutrition guidance following operations involving sleep loss.
