Determining the Relationship between the Length of Fingers and the Dominant Hand Strength in Practiced Female Swimmers

Document Type : Original Article

Abstract

The gripping and pulling strength of the hands is essential to many sports such as rock climbing, wrestling, 
handball, and swimming. This research has aimed to study the relationship between specific anthropometric 
dimensions and the dominant hand strength in practiced female swimmers. In order to do that, 20 female
swimmers of the ages of 11 to 17 who were the members of the board of Mashhad swimming team were 
subjected to fingers' length measuring, using Visnapuu method. Five specific dimensions and 10 ratios (1D/ 
2D, 1D/ 3D, 1D/ 4D, 1D/ 5D, 2D/ 3D, 2D/ 4D, 2D/ 5D, 3D/ 4D, 3D/ 5D, 4D/ 5D) were measured. A digital 
dynamometer was used to measure maximum hand strength. Pearson's correlation tests with the significance 
level of p<0.05 were used to analyze the data. From among the measured parameters, there were significant 
correlations (p<0.05) between the dominant hand strength and the ratios of first finger over fifth finger 
(D1/D5), first finger over second finger (D1/D2), and third finger over fifth finger (D3/D5) in the dominant 
hand. There was also a significant positive relationship between the length of all the fingers in the dominant 
hand and the grabbing strength of the dominant hand.
