About this study

Official title: Effect of the Author's Training Program in Normobaric Hypoxia on Changes in Bone Turnover Markers and Carbohydrate and Lipid Metabolism in Premenopausal Women

The impact of a proprietary training program in normobaric hypoxia on changes in bone turnover markers as well as carbohydrate and lipid metabolism in premenopausal women falls within the realm of physical culture for an active and healthy society. Within this context, the implementation of a project is supported aiming to:

  1. Monitor, support, and promote physical development, fitness, and physical activity in society, by assessing the effects of a proprietary training program in normobaric hypoxia on changes in bone turnover markers as well as carbohydrate and lipid metabolism in premenopausal women.
  2. Develop and implement innovative methods, forms, and means of physical activation and training for individuals of various ages, by formulating general assumptions of an endurance-strength training concept under normobaric hypoxia conditions, concerning changes in bone turnover markers as well as carbohydrate and lipid metabolism in premenopausal women.
  3. Prevent injuries in physical education and sports, by designing a useful training program for osteoporosis prevention as well as for managing carbohydrate and lipid metabolism disorders in premenopausal women.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • exercise and environmental conditionsOther

    Participants will perform endurance-strength training for 4 weeks in a variety of environmental conditions. Somatic indices and quantitative indicators of bone mass (bone mineral density) will be measured both before and after the training period. Before the first training day and the day after the last training day, blood will be drawn for biochemical analysis.

  • exercise and environmental conditionsOther

    Passive exposure to normobaric hypoxia conditions. No training intervention. There will be a measurement of selected somatic indices and a quantitative measurement of bone mass indices (bone mineral density). A blood draw for biochemical analysis will be performed.

Questions about this trial

What is this clinical trial studying?

A study testing exercise and environmental conditions in people with Hypoxia, run by University School of Physical Education, Krakow, Poland at 2 sites 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 4 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 8 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Contact Anna Radoń, MSc (+45126831142, anna.radon@awf.krakow.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Blood analysis- part 1 (time frame: Before (10 minutes) and after (3 minutes) the first and last training.The training will last 4 weeks and will consist of 12 workouts). The study lists 30 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 8 May 2024.
