About this study

Official title: A Randomized Controlled Trial of Time-restricted Diet Combined With Multimodal Aerobic Exercise Intervention on Cardiovascular and Metabolic Health in a Sedentary Population

Objective: This study aims to compare the effects of a combination of time-restricted diet and multimodal aerobic exercise (calisthenics, yoga, and comprehensive physical training) on cardiovascular and metabolic health in a sedentary population with both interventions alone.

Study design. Randomized controlled trial Participants: Sedentary (average sitting time greater than 6 hours per day over the past six months, and average moderate-intensity physical activity less than 125 minutes per week or vigorous-intensity physical activity less than 75 minutes per week as assessed by the International Physical Activity Questionnaire).

Sample size: 81 Study grouping and intervention measures: Subjects who signed informed consent and met the inclusion/exclusion conditions were randomly divided into the following three groups according to gender stratification, with 27 participants in each group: single time-limited diet group, single multi-mode aerobic exercise (aerobics, yoga and comprehensive physical training) group, and combination of time-limited diet and multi-mode aerobic exercise group. The subjects who received the time-restricted diet intervention were allowed to eat only from 7am to 3pm on Tuesdays, Thursdays and Saturdays, and were allowed to drink pure water only during the rest of the day. The subjects who received the multi-mode aerobic exercise intervention carried out the exercise intervention from 6:00 PM to 7:00 PM on Monday, Wednesday and Friday under the unified guidance of the physical education teacher of the Medical Department. All subjects did not limit their total daily energy intake. The intervention lasted eight weeks.

Outcome evaluation indicators: The main indicators of this study were body composition (body fat, muscle mass, fat-free weight, body weight, BMI, body fat percentage, total body water, protein, inorganic salts, limb muscle and extracellular water ratio).

Read the detailed description

Subjects who signed the informed consent and met the inclusion criteria were randomly divided into the following three groups according to gender stratification:

  1. Single time-limited diet group: Subjects in this group were given a time-limited diet every Tuesday, Thursday and Saturday. They were only allowed to eat from 7am to 3pm on the same day, and only allowed to drink purified water during other periods, namely an 8-hour eating window and a 16-hour fasting period. Total daily energy intake is not restricted, and food selection is recommended in accordance with the Dietary Guidelines for Chinese Residents (2022). Subjects in this group were required to maintain the original physical activity frequency;
  2. Independent multi-mode aerobic exercise group: Subjects in this group will do multi-mode aerobic exercise from 6:00 PM to 7:00 PM on Mondays, Wednesdays and Fridays under the unified guidance of the physical education teacher of the Health Science Department (see Attachment 3 for details). The venue is the gymnasium and sports ground of Peking University Health Science Center, and the exercise items include aerobics, yoga and comprehensive physical training, see attachment for details. Subjects in this group do not limit their daily total energy intake, and it is recommended to choose food according to the Dietary Guidelines for Chinese Residents (2022).
  3. Combined group of time-limited diet and multi-mode aerobic exercise: Subjects in this group received the same time-limited diet intervention according to the above requirements of the single-mode diet group every Tuesday, Thursday and Saturday, and the same multi-mode aerobic exercise intervention according to the above requirements of the single-mode aerobic exercise group every Monday, Wednesday and Friday. Total daily energy intake is not restricted, and food selection is recommended in accordance with the Dietary Guidelines for Chinese Residents (2022).

    Also called Multimodal aerobic exercise

    On Tuesdays, Thursdays and Saturdays, only eating is allowed between 7am and 3pm. The rest of the time, only drinking pure water is allowed, which is an eight-hour eating window and a 16-hour fasting period.

    On Mondays, Wednesdays and Fridays, under the unified guidance of the physical education teachers of the Health Science Department from 6:00 PM to 7:00 PM, the venue is the gymnasium and sports field of Peking University Health Science Center.

Questions about this trial

What is this clinical trial studying?

A study testing Time-restricted diet in people with Healthy Population, run by Peking University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Tao Huang, Dr (13488745828 ext. +86, huangtao@bjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body fat (time frame: Baseline survey). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Aug 2023.
