About this study
Official title: Effect of Supervised Physical Exercise on Brain, Cognition, OMICs, Molecular Markers and Functional Status in Older People at Risk of Mild Cognitive Impairment: Rationale, Design and Methodology.
This project aims to examine the effect of a 5-month period supervised exercise intervention on brain, cognition, OMICs, Molecular Markers and functional status in older people at risk of mild cognitive impairment. Secondarily, the effect of this intervention on antioxidant capacity, lipid metabolism and glucose, physical health (functional capacity, blood pressure, body composition) and mental (quality of life and depression) will be studied, as well as other factors risk (genetic and biological) for the development of Alzheimer. A total of 100 people aged between 65 and 75 years old at risk of mild cognitive impairment will be randomly distributed in the supervised exercise intervention group (n = 50) and control group (n = 50). The design will include a 5-month intervention with measurements at pre and post intervention and a third measurement (retest) after 3 months of completion. The multicomponent supervised exercise program will include aerobic, strength, cognitive and coordinative-agility-balance works, and progression will be established in different load parameters (frequency, volume, intensity, density). Therefore, randomized controlled studies are needed to know the specific effect of dose-response considering the various dimensions in parallel such as neuroimaging, cognitive status and OMICS. This will allow us to understand from a comprehensive perspective the causes and mechanisms underlying the response. This project will significantly increase scientific knowledge about the role of exercise on brain as a therapeutic measure in people at risk of mild cognitive impairment from a multidimensional perspective. The project will have a significant impact at social and economic level by transferring the study findings to social and health setting by means of agents and networks provided for the project.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Supervised Exercise ProgrammeBehavioural
The methodology will be multicomponent, including aerobic, strength, coordination-cognitive and balance-agility. The physical exercise sessions will be designed in such a way that they work the dimensions but being attractive and motivating for the participants. Each session will include 10 minutes of warm-up with smooth running and mobility exercises; 35-40 minutes of aerobic, strength, coordination-cognitive and balance-agility progressively developed; and 10 minutes back to calm at low intensity with stretching exercises. Nutritional intervention will not be included. For quality purposes, we will use small groups (10-15 pers). After each session participants will be asked about their subjective perception of the effort and the intensity will be controlled by heart rate monitors.
| Study group | Role | What they receive |
|---|---|---|
| Control Group | No intervention | Participants randomly assigned to control group will be instructed to maintain their normal life habits with respect to physical activity and diet. During the 5 months of intervention participants from this group will receive at least one call from the researchers to be interested in their health status and inform them about the next evaluation appointment, as well as, an objectively evaluation of the main behaviours in the middle of intervention. Investigators will inform about the relevance of attending the full process and respecting the condition and rule as control. Participants from the control group will be freely offered the possibility to get involve in a similar intervention protocol at the end of the study in order to benefit from the potential positive effect of exercise. |
| Supervised exercise programme | Experimental | 5 months of supervised physical exercise program. The individualized and progressive Health periodization model will be applied establishing an initial individualizing period, as well as identifying any need or adaptation to apply during the exercise program. The physical exercise program will be applied in a period of progressive increase whose initial objective will be to reach the volume and intensity established by the international recommendations of physical activity (http://www.health.gov/paguidelines/) for this population. Briefly, a volume of 150 min/week of moderate-vigorous physical activity (60% -85% reserve heart rate) spread over a maximum of 5 days and including force work 2-3 days/week. The training load will progressively increase with a wave and flexible periodization. Receives: Behavioral: Supervised Exercise Programme |

The telomere length will be measured by quantitative real-time PCR (RT-qPCR) following the method previusly described. Briefly, the DNA from the cell fraction of the blood will be extracted with the DNeasy Blood \& Tissue Kit (Qiagen) following the manufacturer's specifications. The DNA concentration of the sample, as well as its integrity, will be confirmed in a NanoDrop 2000. For the RT-qPCR the telomeric sequence will be amplified as well as a single copy gene sequence to normalize. Calibration curves will be made with serial dilutions of known concentration of both the gene sequence as well as an oligo specially designed to contain 114 copies of the TTAGGG telomeric sequence. The RT-qPCR will be carried out with 20 ng of DNA using myScript SYBR Green PCR Kit (ROCHE). The PCR conditions are: 10 min at 95 ° C, followed by 40 cycles of 95 ° C for 15 sec and 60 ° C for 1 min, followed by the corresponding dissociation curve.

Questions about this trial
What is this clinical trial studying?
A study testing Supervised Exercise Programme in people with Mild Cognitive Impairment and Alzheimer Dementia, run by University of Cadiz at 1 site in Spain.
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 3 inclusion and 12 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: finished, as of the sponsor's last update on 27 Apr 2021. 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?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03923712, which also lists 1 linked publication.
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?
