University of Thessaly13 enrolled

Overview

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.

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.

Interventions

Exercise training programBEHAVIORAL

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.
