About this study
Official title: Effect of Time-restricted Eating and Endurance Training on Markers of the Health of Women and Men-role of Dietary Supplements
The aim of this project is to demonstrate the synergistic effect of TRE and NW training on health indicators for older women. The women will be divided into four groups, i.e. Control group (CG); time-restricted eating group (TRG) which will follow 12 weeks of TRE protocol; Nordic walking training group (NWT) which will follow 12 weeks of supervised Nordic walking training and Nordic walking training combined with a time-restricted eating group (NW-TRG). In addition, it is assumed to prove that among young men, TRE will improve adaptation to endurance training and improve the metabolism. The study will be divided into two groups: 1. a group undergoing endurance training and 2. a group combining endurance training with TRE. In all subject's changes in the metabolism of iron, tryptophan, vitamin D and lipids will be evaluated. Endocrine function of skeletal muscles, mental state and cognitive abilities of the subjects will also be examined. The investigators expect that the applied procedure of temporary restriction of food intake will be easy to apply and continue for much longer than the study period. In order to maintain this time window, test subjects will be asked to delay their breakfast and early dinner intake. In addition, it is expected that the improvement in wellbeing, vitality and a significant improvement in performance and biochemical indicators of health, especially in the NWT plus TRE group, will allow to better understand the physiology of exercise, which may result in future specific health recommendations for people of different ages.
Read the detailed description
Studies of recent years prove that one of the important causes of metabolic disorders in people is a disturbed daily cycle, which is significantly influenced by the time of eating. It has been shown that more than 50% of the examined persons consumed food for 15 hours and more during the day. Limiting food consumption to 8-10 hours, without the need to reduce food intake, the so-called time-restricted eating (TRE), resulted in a significant improvement in metabolism, decrease in body weight and cholesterol concentration, increase in insulin sensitivity and many others. A period of hunger is necessary for the body to regenerate cell structures and allows for the separation of opposing metabolic processes. This means that the period of hunger is necessary and its limitation by e.g. snacking can seriously disturb this series of processes in the human body. The results of the investigators preliminary research indicate that TRE increases the vitality of the examined persons and their desire for doing exercise. So far, there are no studies on older people, where the intervention would consist in the use of TRE and endurance training such as Nordic walking (NW). The aim of this project is to demonstrate the synergistic effect of TRE and NW training on health indicators for older women. The women will be divided into four groups, i.e. Control group (CG); time-restricted eating group (TRG) which will follow 12 weeks of TRE protocol; Nordic walking training group (NWT) which will follow 12 weeks of supervised Nordic walking training and Nordic walking training combined with a time-restricted eating group (NW-TRG). In addition, it is assumed to prove that among young men, TRE will improve adaptation to endurance training and improve the metabolism. The study will be divided into two groups: 1. a group undergoing endurance training and 2. a group combining endurance training with TRE. In all subject's changes in the metabolism of iron, tryptophan, vitamin D and lipids will be evaluated. Endocrine function of skeletal muscles, mental state and cognitive abilities of the subjects will also be examined. The investigators expect that the applied procedure of temporary restriction of food intake will be easy to apply and continue for much longer than the study period.

Questions about this trial
What is this clinical trial studying?
A study testing Time restricted eating and exercise in people with Physical Exercise and Time Restricted Eating, run by Medical University of Gdansk at 1 site in Poland.
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 2 inclusion and 5 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: under way, not looking for participants, as of the sponsor's last update on 24 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time restricted eating and physical performance (time frame: 12 weeks). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05229835, which also lists 2 linked publications.
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 24 Jul 2023.
