THE RELATIONSHIP BETWEEN DIGIT RATIO (2D:4D) AND CARDIOVASCULAR CAPACITY IN YOUNG ADULTS

Abstract

Aims: The ratio of the second-to-fourth finger length was first proposed as a prenatal testosterone biomarker. Studying this matter with a different point of view, the aim of this study is to find whether there is a positive relationship between digit ratio and cardiovascular capacity.Methods: The data of 82 students who were between the ages of 18 and 25 old from Trakya University Faculty of Medicine were analyzed by evaluating the results of the six-minute walking test and the results of their digit measurements. Independent Samples T-Test was used to determine the correlation between the prevalence of longer 4th digit and six-minute walking test results.Results: The data obtained from the test results of the students, that were grouped regarding digit ratio, were statistically evaluated. With the results of the six-minute walking test, students that have lower digit ratio walked 593.87 ± 73.2 meters while students with higher digit ratio walked 584.17 ± 71 meters showing us that there is not a significant relationship between cardiovascular capacity and digit ratio.Conclusion: With the gathered information and results, it is seen that there is not a positive relationship between digit ratio and cardiovascular capacity. In conclusion it can be said that digit ratio does not have a beneficial effect on a persons cardiovascular capacity. Usage of digit ratio as a prenatal hormone exposure has been increasing, and extensive studies in physiological and psychological conditions in humans have been correlated with digit ratio, including athletic ability, fertility, social behaviors, sex-biased diseases, and sexual orientation
