“…The levels of sex hormones in the body is associated with the ratio of the second (2D) (index finger) and fourth (4D) (ring finger) fingers. The 2D:4D ratio refers to the ratio of the length of the index finger to the length of the ring finger [ [4] , [5] , [6] , [7] , [8] , [9] ]. During the prenatal period, the hormones estrogen and testosterone promote the growths of the 2nd finger (2D) and the 4th finger (4D), respectively.…”

“…While the group 1 (2D < 4D) is predominately seen in males, the group 3 (2D > 4D) is predominately seen in females. This means that the gene for short index finger is dominant in males and recessive in females [ 9 , 12 ]. The index finger is generally shorter than the ring finger in males, while this is opposite in females [ 13 ].…”

Introduction: Physical fitness and anthropometric variables are crucial in achieving success in the field of sports. These variables serve as the foundation and platform for children to showcase their athletic abilities. The aim of this study is to examine the impact of somatotype profiles of children aged 48-72 months on athletic performance in order to contribute to talent selection. Methods: A total of 124 students (62 females, 62 males), aged between 48 and 72 months (mean age of females: 5.75±1.00, mean age of males: 5.68±1.15), participated in the study. Somatotype analysis was performed using the Heath-Carter method. Performance measurements of students included a 20-meter sprint test, flexibility, leg strength, push-up tests, crunches, vertical jump, standing long jump, hand strength, back strength, and hamstring length determination tests. Results: In this study, there was a significant difference in favor of mesomorphic endomorph in crunches (F=3.914, p=0.013) and push-up (F=4.864, p=0.004) exercises for female children compared to all somatotypes. In male children, although the central group was dominant in athletic performance measurements, there was no statistically significant difference (p>0.05). Conclusion: Somatotype is a suitable method for enhancing athletic performance and directing individuals to the appropriate sports discipline. Somatotype profiles are not fully developed in children aged 48-72 months. In the later years, children with suitable somatotypes are expected to demonstrate improved athletic performance.

Are alternative variables in a set differently associated with a target variable? Statistical tests and practical advice for dealing with dependent correlations

The analysis of multiple bivariate correlations is often carried out by conducting simple tests to check whether each of them is significantly different from zero. In addition, pairwise differences are often judged by eye or by comparing the p‐values of the individual tests of significance despite the existence of statistical tests for differences between correlations. This paper uses simulation methods to assess the accuracy (empirical Type I error rate), power, and robustness of 10 tests designed to check the significance of the difference between two dependent correlations with overlapping variables (i.e., the correlation between X1 and Y and the correlation between X2 and Y). Five of the tests turned out to be inadvisable because their empirical Type I error rates under normality differ greatly from the nominal alpha level of .05 either across the board or within certain sub‐ranges of the parameter space. The remaining five tests were acceptable and their merits were similar in terms of all comparison criteria, although none of them was robust across all forms of non‐normality explored in the study. Practical recommendations are given for the choice of a statistical test to compare dependent correlations with overlapping variables.
