“…Studies conducted on male and female athletes demonstrated that the frequency of left-handers was more among athletes who managed to receive a medal than those who did not. Also, the number of victories and obtained scores in the lefthanders was more than right-handers or individuals without a clear hand preference (10).…”

Background and Purpose: Through comparing handedness and laterality between successful athletes and ordinary people, this study endeavored to investigate the probable relationship between these two factors and skills and abilities which distinguish successful athletes from other members of the society. Procedure: The sample population in the current study included Iranian men and women who were assigned into two groups of ordinary population (group 1) and successful male and female athletes (group 2). Carter’s Laterality Inventory and The Edinburgh Handedness Inventory were employed to measure laterality and handedness, respectively. It needs to be noted that validity and reliability of Persian translation of both inventories have been proved. Following the completion of the inventories, individuals’ laterality and handedness were determined, and the data were prepared for statistical analysis. Findings: The participants included 212 individuals, out of which 135 (63.7%) were male and 77 (36.3%) were female. The individuals were compared in two groups. The first group consisted of successful athletes. Out of the 130 individuals, 45 (34/6%) were female and 85 (65/4%) were male. The second group were ordinary people from private schools in Tehran which entailed 32 (39%) women and 50 (61%) men.

“…Even though RAE is a widespread phenomenon in different individual 20,21 and invasion team sports [22][23][24][25][26][27] , investigations in water sports focus on swimming [28][29][30] , being scarce in water polo [31][32][33] . In addition to that, the results from studies that investigated RAE in water polo are inconsistent.…”

To investigate the existence of relative age effect (RAE) in Brazilian water polo athletes according to sex and age category. Methods: The birthdate of 574 Brazilian water polo athletes were organized according to the athletes' birthdates into quarters of the year (Q1, Q2, Q3, and Q4), and classified according to sex (male and female) and age category (U16, U18, U20, and senior). To verify the existence of RAE, the Chi-Square tests (χ 2 ) were performed, and the effect sizes (ω) were calculated for each of the tests. We also calculated odds ratio (ORs) and 95% confidence intervals, setting the level of significance to 0.05. As post hoc analysis, multiple comparisons between quarters were performed, with Bonferroni's correction (significance level set to 0.0083 in these cases). Results: The results indicated an uneven distribution of birthdates for male water polo athletes (χ 2 = 12.257; p = 0.007; ω = 0.173), with an overrepresentation of athletes born in the first (p < 0.006) and second (p < 0.002) quarters. When sex and age category were considered, male athletes presented uneven distributions in U20 (χ 2 = 10.747; p = 0.013; ω = 0.345) and senior (χ 2 = 12.614; p = 0.006; ω = 0.383) categories. In females, no differences were found. Conclusion: We conclude that there is an uneven distribution of birthdates in male Brazilian water polo athletes, indicating the presence of RAE in this group.

“…Relative age and maturation have been observed to influence the athlete's selection of different sports features, such as playing positions [7], chronological age and performance [8], effectiveness in the match [9], and the laterality in individual sports [10]. When evaluating the potential of a young athlete, the maturational factor must also be considered and monitored [1].…”

Purpose. the relative age effect (RAE) is a widely reported phenomenon in elite sports context. However, little is known about its occurrence in other levels of practice, such as school sports. thus, this study aimed to investigate the presence of RAE on Mato Grosso state (Brazil) student-athletes participating in National School Games depending on sex, age category, and sport type. Methods. Data from 440 student-athletes of Mato Grosso state (Brazil) who participated in 2 National School Games: 2019 Youth School Games (n = 250) and 2021 Brazilian School Games (n = 190) were organized depending on their quarters of birth. Chi-square tests were performed to compare their birthdates distribution in accordance with sex (male and female), age category (12-14 years old and 15-17 years old), and sport type (team and individual sports). Results. Athletes born in the first months of the year were more frequent than athletes born in the last months of the year in the overall sample, in males, in the younger age category, and in team sports (p < 0.008). On the other hand, no differences were found for females, athletes from the older age category, or athletes practising individual sports (p > 0.05). Conclusions. RAE is pervasive in the student-athletes of Mato Grosso state (Brazil), specifically for male athletes in early categories of team sports. Educating coaches regarding this effect and implementing specific counter-RAE interventions are warranted to minimize selection bias in this sports context.
