Relationships between the digit ratio (2D:4D) and game‐related statistics in professional and semi‐professional male basketball players

Abstract

Objectives: The primary aim of this study was to examine relationships between digit ratio (2D:4D) and game-related statistics in professional and semiprofessional male basketball players. The secondary aim was to quantify differences in mean 2D:4Ds between starting and reserve players. Methods: Using a cross-sectional design, 93 male basketball players from the professional Australian National Basketball League and the semi-professional South Australian Premier League were measured in-season for height, mass, and 2D:4D, with game-related statistics collected end-season. Linear relationships between right and left 2D:4Ds and game-related statistics were quantified using nonparametric partial correlations, and differences in mean 2D:4Ds between starting and reserve players were quantified using analysis of covariance (ANCOVA). All partial correlations and ANCOVAs were adjusted for playing experience, body size, and competitive standard. Results: 2D:4D was a weak to moderate negative correlate of points scored and assists-to-turnovers ratio, indicating that males with lower 2D:4Ds were generally better offensively as they recorded more points and assists relative to turnovers. The difference in mean 2D:4D between starting and reserve players was negligible. Conclusions: 2D:4D was favorably correlated with open-skill sports performance, as evidenced by the better offensive statistics of male basketball players with lower 2D:4Ds. These results probably reflect the organizational benefits of prenatal testosterone and indicate that 2D:4D may be a useful complement to traditional physical, physiological, skill, and behavioral predictors of basketball success.anthropometry, finger ratio, males, physical performance, sportThe digit ratio (2D:4D) is the ratio of the length of the second digit (2D; the index finger) and the fourth digit (4D; the ring finger). Evidence indicates that 2D:4D is developmentally stable and fixed as early as the second semester of pregnancy (Malas,

Digit ratio (2D:4D), myocardial infarction and fibrinogen in men

“…There is a robust negative correlation between 2D:4D and performance in many sports [36]. However, the effect size varies across sports such that closed disciplines that place emphasis on endurance, such as distance running, show greater effect sizes than those that require strength and/or open interaction with other participants [37,38]. This pattern may, in part, reflect a positive correlation between 2D:4D and blood levels of fibrinogen.…”

The 2nd:4th digit ratio and shooting skill performance in Basketball Players

“…Test and other 2D and 4D parameters (p>0.05) (Table 1). As a result of their study, Klapprodt et al (2018) show that 2D: 4D is significantly associated with sports, athletic and fitness test performance.…”

“…Therefore, the aim of this study is to expand the missing literature that Frick et al (2017), Dyer et al (2018), andKlapprodt et al (2018) refer to as suggestions in their studies. The aim of this study is to measure the differences and relationship in 2D:4D in shooting skills on basketball players.…”

Associations between bio-motor ability, endocrine markers and hand-specific anthropometrics in elite female futsal players: a pilot study

“…Exposure to intrauterine sex hormones on selective sexual adaptations is thought to play a key role in female intrasexual competition. Also, several studies have examined the relationship between 2D:4D ratios and physical fitness parameters and found a significant correlation in this regard with the variables of performance, strength, power and endurance of male basketball players [ 19 ].…”
