简要总结
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.

研究组 & 干预措施
Control
The Control group will follow their usual eating routine.
early time-restricted eating
The Early Time Restricted Eating (eTRE) group will be asked to consume calorie containing food or drinks only between 9am to 5pm, daily. At other times they are to avoid consuming any calorie containing food or drinks.
干预措施: early time restricted eating (Behavioral)
