Trial summary

Matrix metalloproteinases (MMPs) play a critical role in the remodeling and regeneration of skeletal muscle. Studies which investigate exercise and effects of MMPs and tissue inhibitors of matrix metalloproteinases (TIMPs) are contradictory. Read more about this study

About this study

Official title: The Effect of Maximal Exercise on Matrix Metalloproteinase Enzyme and Its Inhibitor (MMP9 and TIMP1) and The Role of MMP9 -1562 C/T and TIMP1 372 T/C Polymorphisms

Matrix metalloproteinases (MMPs) play a critical role in the remodeling and regeneration of skeletal muscle. Studies which investigate exercise and effects of MMPs and tissue inhibitors of matrix metalloproteinases (TIMPs) are contradictory. Also the role of MMP9 -1562 C/T and TIMP1 372 T/C polymorphisms on exercise are unclear. In accordance with this conditions the hypothesis of the study are as follows:

  1. Levels of basal serum MMP9 and TIMP1 are different between athletes (volleyball, basketball, handball) and sedentary people.
  2. Levels of serum MMP9 and TIMP1 response to maximal exercise are different between athletes (volleyball, basketball, handball) and sedentary people .
  3. Relationship between levels of serum MMP9 and TIMP1 response to maximal exercise are different between athletes (volleyball, basketball, handball) and sedentary people.
  4. Levels of basal serum MMP9 and TIMP1 are related to MMP9 -1562 C/T and TIMP1 372 T/C polymorphisms.
  5. Relationship between levels of serum MMP9 and TIMP1 response to maximal exercise and MMP9 -1562 C/T and TIMP1 372 T/C polymorphisms are different between athletes (volleyball, basketball, handball) and sedentary people.

What participants receive

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

  • Yo-Yo Intermittent Recovery Test Level 1Other

    The test is a standard test battery with progressively increasing speeds. After every 40-m run (2x20 m), active rest is performed by walking or jogging at a distance of 10 m (2x5 m). for 10 seconds. Participants are trying to adjust their speed according to incoming audio signals.The test is terminated when the participants can not reach the signal twice. The test ends in 10-20 minutes depending on the level of participants.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of MMP9 and TIMP1

    The effect of acute maximal exercise on serum MMP9 and TIMP1 levels in athletes and sedentary people.

    Measured: Yo-Yo Intermittent Recovery Test level 1 (the test performed until the subject is exhausted, the test lasts 10-20 minutes according to endurance capacity of the participants)

  2. MMP9 -1562 C/T, TIMP1 372 T/C polymorphisms

    The role of MMP9 -1562 C/T and TIMP1 372 T/C polymorphisms on the effect of acute maximal exercise on serum MMP9 and TIMP1 in athletes and sedentary people.

    Measured: Yo-Yo Intermittent Recovery Test level 1 (the test performed until the subject is exhausted, the test lasts 10-20 minutes according to endurance capacity of the participants)

Secondary outcomes (2)
  1. Level of indicators of muscle damage and inflammation and oxidative stress

    The relationship between primary outcome measures and indicators of muscle damage, inflammation and oxidative stress.

    Indicators to be determined: creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), Interleukin-6 (IL-6), C- reactive protein (CRP), total antioxidant status (TAS), total oxidant status (TOS), nitric oxide (NO)

    Measured: Yo-Yo Intermittent Recovery Test level 1 (the test performed until the subject is exhausted, the test lasts 10-20 minutes according to endurance capacity of the participants)

  2. Level of blood lipids and lipoproteins, glucose, urea, creatinine, hemogram

    The relationship between primary outcome measures and blood lipids and lipoproteins, glucose, urea, creatinine and hemogram

    Measured: Yo-Yo Intermittent Recovery Test level 1 (the test performed until the subject is exhausted, the test lasts 10-20 minutes according to endurance capacity of the participants)

Questions about this trial

What is this clinical trial studying?

A study testing Yo-Yo Intermittent Recovery Test Level 1 in people with MMP9 and TIMP1, run by Dokuz Eylul University at 1 site in Turkey (Türkiye).

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 7 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: finished, as of the sponsor's last update on 30 Apr 2020. 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 Turkey (Türkiye). 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Level of MMP9 and TIMP1 (time frame: Yo-Yo Intermittent Recovery Test level 1 (the test performed until the subject is exhausted, the test lasts 10-20 minutes according to endurance capacity of the participants)). The study lists 2 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 30 Apr 2020.
