Effects of Early Time Restricted Eating on Muscle Performance in Resistance Trained Individuals
- Conditions
- Time Restricted Eating
- Registration Number
- NCT05908201
- Lead Sponsor
- University of Mississippi, Oxford
- Brief Summary
A randomized controlled trial to determine the effectiveness of early time-restricted eating on muscle performance and body composition in active, resistance trained adults. Two parallel groups will be randomly assigned to either the early time-restricted eating or a control group. All participants will be asked to maintain their usual exercise routines during the 6 week intervention period. Muscle strength and endurance are the primary outcomes. Body composition (body weight, fat mass, fat-free mass and percent body fat), hunger and satiety ratings, sleep quality, energy intake, diet quality, macronutrient composition and adherence are secondary outcome measures.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- PARALLEL
- Primary Outcome Measures
Name Time Method Muscular strength 6-weeks Pre and post intervention testing of muscular strength using one-rep max
Muscular endurance 6-weeks Pre and post intervention testing of muscular endurance using barbell bench press and squat.
- Secondary Outcome Measures
Name Time Method Body weight (kg) 6-weeks Pre and post intervention measures of body weight.
Total calorie intake 6-weeks Pre and post intervention measurements of calorie intake based on 24-hour food recall survey using the Automated Self-Administered 24-hour (ASA24) software.
Diet macronutrient composition 6-weeks Pre and post intervention measurements of macronutrients based on 24-hour food recall survey using the ASA24 software.
Diet Quality 6-weeks Pre and post intervention measurements of diet quality based on 24-hour food recall survey using the ASA24 software and Healthy Eating Index.
Adherence 6-weeks Percent of days during the 6-week trial when eTRE was adhered to as recommended. This will be recorded by the participants daily throughout the entire study.
Hunger and satiety 6-weeks Pre and post intervention subjective measure of hunger and satiety with the use of a Hunger and Satiety Visual Analog Scale (minimum value zero, maximum value 10). Higher the score, the more hungry/ less satiated one is.
Fat mass 6-weeks Pre and post intervention measurements of body fat mass (kg).
Fat-free mass 6-weeks pre and post intervention measurements of body fat-free mass (kg).
Sleep quality 6-weeks Pre and post intervention measure of subjective sleep quality by use of Pittsburgh Sleep Quality Scale. (each question can be scored from 0-3, then an aggregate score of the whole survey can range from 0-21; The higher the score the worst the sleep quality).
Body fat percentage 6-weeks Pre and post intervention measurements of body fat percentage.
