Four Weeks Of Time-Restricted Feeding Combined With Resistance Training Does Not Differentially Influence Measures Of Body Composition, Muscle Performance, Resting Energy Expenditure, And Blood Biomarkers
|Values||There was no significant group x time effect on muscle morphology. However, the density and cross-sectional area of the vastus lateralis, and the cross-sectional area and length of the biceps brachii were increased in both groups.|
|Trial Design||Randomized trial|
|Trial Length||2-4 Weeks|
|Number of Subjects||26|
Participants were assigned to either do a 16:8 time-restricted eating protocol or a normal diet while engaging in a resistance training program for four weeks. Both diets had a 25% caloric deficit, and had the same macronutrient composition. Protein intake was 1.8 g/kg/day for both groups. Participants completed two visits before and after the intervention. In the first visit, resting energy expenditure and body composition (via ultrasound) were measured, and blood was collected. On the second visit (48 to 96 hours later), vertical jump and estimated one rep max and reps to fatigue for leg press and bench press were measured.
