About this study

Official title: Dose-response Effects of Different Volumes of Structured Exercise in the Inflammatory and Oxidative Stress Parameters in Postmenopausal Women: a Randomized Clinical Trial

The investigators will do an intervention on four groups of previously sedentary post-menopausal women which consists: group 1 - 30 minutes per day of physical protocol; group 2 - 50 minutes per day of physical protocol; group 3 - 70 minutes per day of physical protocol; group 4 - sedentary control women. The protocol consists of three sessions per week of concurrent training (half session with aerobic training and the other part with weight training). Inflammatory and oxidative parameters will be analyzed and the investigators hypothesized that 90 minutes per week of concurrent training (group 1) will reduce the inflammatory parameters and the oxidative stress, and this improvements will be greater so much as the longer the sessions (a dose-response effect). The physical activity practiced out of the intervention will be controlled by a questionnaire (the commuting and leisure sections of the International Physical Activity Questionnaire) and the food intake by a 24-hour food recall.

Read the detailed description

The protocol will consist of an intervention based on concurrent training, for previously sedentary post-menopausal women divided on four groups: 1) control group; 2) 90 minutes of physical training per week; 3) 150 minutes of training per week; 4) 210 minutes of training per week.

The control group will be oriented to maintain their normal activity and habits and will not receive the intervention. The group of 90 minutes per week will do three sessions of 30 minutes per week of concurrent training, which consists on 15 minutes of aerobic exercise and 15 minutes of strength training. The group of 150 minutes will do three sessions of 50 minutes per week, which consists on 25 minutes of aerobic exercise and 25 minutes of strength training. The group pf 210 minutes per week will do three sessions of 70 minutes per week, which consists on 35 minutes of aerobic exercise and 35 minutes of strength training.

The aerobic exercise will be performed on cycle-ergometers and the subjects will exercise between the levels 14 and 15 of Borg's scale of perceived exertion. The strength training will be performed on weight machines by a linear periodization, which will consist on a week of adaptation (series of 10 to 12 submaximal repetitions), next three weeks with series of 12 to 14 maximal repetitions, weeks five to eight with series of 10 to 12 maximal repetitions, weeks nine to twelve with series of eight to 10 maximal repetitions. Al participants will do the maximum number of series of strength training that the time permits.

The blood samples will be collected at the beginning of the study (week zero), at the middle (week six) and at the end (week 12). The subjects will fill a 24-hour food recall (to control the food intake) and the commuting and leisure sections of the International Physical Activity Questionnaire (to control the physical activity practiced out of the intervention).

Questions about this trial

What is this clinical trial studying?

A study testing Physical exercise intervention in people with Immune System Diseases and Oxidative Stress, run by Federal University of Pelotas.

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 1 inclusion and 3 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 29 Sep 2016. 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?

Yes. Results are posted in the registry (first posted 23 Aug 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Interleukin-6 (time frame: Weeks 0, 6 and 12). The study lists 7 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 29 Sep 2016.
