Relationship between 2d:4d ratio, handgrip strength, and hamstring muscle length in different sports: a study of volleyball, football and basketball branches

Background and Study Aim. The relationship between the 2nd digit (2D) 4th (4D) provides much preliminary information about physiological, psychological, psychomotor characteristics of individuals. Although there are many studies on 2D:4D ratio, number investigating ratio in different sports is limited. Therefore, purpose this study to determine posterior thigh muscle length, handgrip strength sports.
 Material Methods. 63 athletes aged 18-29 years from football, volleyball basketball participated (nFutbol=20, nVoleybol=21, nBasketbol=22). Right left hand width 2D, 4D, grip strength, hamstring length participants were determined. When examining parameters, Pearson correlation analysis was performed.
 Results. In study, a high right width, 4D measurements players (p<.05). There also moderate football players’ 2D branches, no parameter associated with players. Sport age For volleyball, athletic measures basketball, length.
 Conclusions. results suggest that some can be used predict performance indicators such as basketball.
