About this study

Official title: Effects of Long-term Exercise on Psychological, Physiological, Biochemical and Alcohol-related Parameters in Heavy Drinkers

The purpose of this research is to examine the effects of long-term aerobic exercise of moderate intensity on psychological, physiological, biochemical, physiological and alcohol-related parameters in heavy drinkers, in order to investigate possible biochemical mechanisms by which exercise may be a healthy alternative to alcohol abuse.

Read the detailed description

The mechanism of incentives that lead people to unhealthy habits such as excessive alcohol consumption is not only social, personal, and psychological, but also associated with neurochemical and neurobiological mechanisms.

Several programs have been developed to stop excessive drinking, but the success rates are small, while the relapse rates are very high, reaching up to 90%. Although there is some evidence for the beneficial effects of exercise on alcohol use disorders, research is limited. The present study investigates whether exercise can act as adjunct therapy for alcohol abuse cessation.

One of the basic assumptions is that the appropriate form of exercise in alcoholics will contribute to the secretion of beta-endorphin, which in combination with psychological pleasure, vitality, change of mood, reduced stress, increased confidence, and the shift of attention will help people to follow healthy lifestyles and abhor alcohol.

The research project is divided in three phases. In the first phase, the effect of acute exercise in critical psychological, physiological, biochemical and alcohol-related parameters associated with excessive alcohol consumption will be examined. In the second phase (current study), a long-term exercise program in conjunction with psychological support strategies aimed at alcohol abuse cessation will be developed, implemented and evaluated. Finally, in the third phase, based on the results of the previous phases, awareness programs in adolescent and adult populations will be designed and implemented as well as the dissemination of results and evaluation of the project will take place.

What participants receive

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

  • Exercise training programBehavioural

    Supervised 8-week exercise training program. Aerobic exercise (walking, jogging) of increasing duration at 50-60% HRR, at least two sessions per week. Participants will be recording their daily alcohol consumption. Participants will also undergo three trials of acute exercise (before, at the 4th week and at the 8th week of exercise training) in order to investigate whether exercise training can lead to changes in acute responses to exercise. Each trial involves 30 min of exercise on a cycle ergometer at 50-60% HRR.

Questions about this trial

What is this clinical trial studying?

A study testing Exercise training program in people with Heavy Drinking and Alcohol Abuse, run by University of Thessaly.

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 2 inclusion and 1 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 Jan 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?

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?

Changes in alcohol consumption (grams of alcohol consumed weekly) (time frame: At baseline and at 4th week of control condition; at baseline (before intervention), at 4th week and at 8th week of intervention). 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 27 Jan 2016.
