About this study

Official title: Effects of Hardaliye, a Fermented Grape Drink, on Oxidative Stress, Lipid Profile and Blood Pressure in Young Footballers: A Randomised Trial

In the present study, the authors aimed to investigate the effects of hardaliye (grape juice) consumption on oxidative stress parameters, lipid profile and blood pressure in young football players.

Being tested
Grape juice, Placebo drink

What participants receive

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

  • Grape juiceOther

    Hardaliye (grape juice) is a fermented, traditional non-alcoholic beverage made from fresh grapes. It is mainly produced by the fermentation of grapes, sour cherry leaves and mustard seeds. Hardaliye was purchased from traditional producers in Turkey. Hardaliye Group consumed 250 ml/day of hardaliye (grape juice) for 28 days.

  • Placebo drinkOther

    Placebo drink has carbohydrate, energy and sensory properties similar to hardaliye. Placebo Group consumed 250 ml/day of placebo drink

What is being measured

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

  1. Change in total antioxidant capacity

    Measurement of serum level of total antioxidant capacity (μmol Trolox eq/L).

    Measured: 28 days

  2. Change in total oxidation status

    Measurement of serum level of total oxidation status (μmol H2O2 eq/L).

    Measured: 28 days

  3. Change in oxidative stress index

    (Serum level of total oxidation status/serum level of total antioxidant capacity) × 100

    Measured: 28 days

  4. Change in lipid parameters

    Measurement of serum levels total cholesterol (mg/dl), HDL-cholesterol (mg/dl), LDL-cholesterol (mg/dl) and triglycerides (mg/dl).

    Measured: 28 days

  5. Change in blood pressure

    Measurement of systolic (mm Hg) and diastolic blood pressure (mm Hg)

    Measured: 28 days

Secondary outcomes (1)
  1. Change in perceived exercise-induced pain

    Perceived exercise-induced pain was determined using the 100-mm Visual Analog Scale. 100-mm Visual Analog Scale scores range from 0 (no pain) to 100 (most severe pain). A higher score indicates a higher perceived pain level.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A study testing Grape juice in people with Diet, Healthy and Antioxidative Stress, run by Medipol 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 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: finished, as of the sponsor's last update on 10 Feb 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 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. Some participants in this study may receive a placebo. 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?

Change in total antioxidant capacity (time frame: 28 days). The study lists 5 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 10 Feb 2023.
