|dc.description.abstract||Aim: Exercise is known to affect both the morphological and functional properties of the
heart. More aerobically trained individuals possess larger cardiac chamber dimensions
and wall thicknesses than untrained individuals, however evidence is controversial as to
whether these morphological differences translate to a difference in systolic function.
Alcohol consumption, including the consumption of high quantities of alcohol in a short
period of time (a 'binge drinking' pattern), is known to influence cardiac properties.
However, there is little exploration into the combined effects of aerobic fitness and alcohol
consumption upon the structure and function of the heart. Therefore the aim of this study
was to explore whether alcohol consumption influences the relationship between aerobic
fitness and systolic function in a population of trained and untrained University students.
Methods: 11 males (age 20.8 ± 1.5 years) were recruited from a University population.
Alcohol consumption (measured via the AUDIT questionnaire), fitness (quantified via 2
max) and systolic echocardiographic data were collected from all participants.
Results: Correlational analyses revealed that a positive linear relationship existed
between increased aerobic fitness and stroke volume, end diastolic volume and posterior
wall thickness of the left ventricle (Pearson correlation coefficents 0.608, 0.696 and 0.623
respectively, all P < 0.05). A novel variable was created to assess the additional influence
of alcohol consumption upon this relationship. It was found that cardiac parameters are
related to 2 max but when alcohol consumption is factored into this analysis, the
relationship disappears.Conclusion: These findings suggest that a lifestyle balance between fitness and alcohol consumption can influence the structure and function of the left ventricle.||en_US
