Interventions

  • Early Time-Restricted Eating (eTRE)+Exercise Intervention — BEHAVIORAL
    Participants will follow an Early Time-Restricted Eating protocol consisting of a 16:8 fasting-feeding schedule. All daily caloric intake will be consumed within an 8-hour window (e.g., 07:00-15:00), followed by a 16-hour fasting period. Participants will be instructed to maintain adequate energy intake and consume at least 1.2 g/kg/day of protein, distributed across meals within the eating window. Water intake will be allowed ad libitum during fasting hours. A supervised multicomponent exercise program including resistance, aerobic, balance, and flexibility training. Sessions will be performed three times per week for 6 months. Resistance training will be performed at 60-80% of one-repetition maximum, aerobic training at moderate intensity (50-70% of maximum heart rate), and balance and flexibility exercises will be included in each session to improve functional capacity in older adults.

Study Details

This randomized controlled trial aims to investigate the effects of Early Time-Restricted Eating (eTRE) combined with a multicomponent exercise program on bone health, physical function, and fall risk in healthy older adults. A total of approximately 44 healthy adults aged 60 years and older will be recruited and randomly assigned to one of two groups. The experimental group will follow an Early Time-Restricted Eating schedule combined with a structured multicomponent exercise program. The control group will not receive any dietary timing intervention or structured exercise program and will continue their usual daily lifestyle. The intervention will last for 6 months. Participants in the exercise program will perform supervised sessions including resistance training, balance exercises, aerobic activity, and flexibility exercises. The Early Time-Restricted Eating protocol will involve consuming all daily food intake within an early daytime window while maintaining usual dietary quality and adequate energy and nutrient intake. The main outcomes of the study include changes in bone mineral density, gait performance, balance, and fall risk. These outcomes will be measured at baseline and after the intervention period. This study will provide evidence on whether combining early time-restricted eating with structured exercise can improve musculoskeletal health and functional ability, and reduce fall risk in older adults.

Arms

  • Experimental: Early Time-Restricted Eating (eTRE)+Exercise Intervention Group
    Participants in the experimental group will follow a 16:8 Early Time-Restricted Eating protocol combined with a supervised multicomponent exercise program for 6 months. The exercise program includes resistance, aerobic, balance, and flexibility training, while the eating window is restricted to 8 hours per day with adequate energy and protein intake maintained.
  • No Intervention: Control
    Participants in the control group will not receive any structured exercise program or dietary timing intervention and will be instructed to maintain their habitual diet and physical activity throughout the study period.
