Digit ratio (2D:4D) and performance in non-elite male badminton players

Padmapriya Krishnakumar, Sudhakar H H.


Abstract
Background: The second to fourth digit ratio (2D:4D ratio) is derived by dividing the length of the index finger (2D) by the length of the ring finger (4D). It has been considered as an index of how much the fetus is exposed to testosterone in utero. Research has suggested that high levels of testosterone are associated with low 2D:4D ratio. The relationship between 2D:4D ratio and physical performance is still an unexplored field in badminton players.

Aims and Objectives: This study intends to assess the digit ratio 2D:4D in non-elite male badminton players in comparison to their sedentary controls.

Materials and Methods: The study included 30 male badminton players in the age group of 19–23 years who were practicing badminton for more than 3 years and 30 age, body mass index-matched sedentary controls. The second and fourth finger measurements were taken from scanned printouts using Vernier calipers.

Results: The 2D:4D ratio was significantly lower in the left hand of badminton players when compared to their controls (P = 0.0001). There was no significant difference in 2D:4D ratios of the right hand and 2D:4D (Δ r–l) between badminton players and controls.

Conclusion: There was significant difference in the ratio of 2nd–4th digit between badminton players and controls in the left hand but not in the right hand. The reason for no difference in 2D:4D ratio and controls in the right hand could be due to the fact that badminton is a moderate intensity sport, and also, the study participants were non-elite players.

Key words: Digit Ratio; Badminton Players; Performance
