Dermatoglyphic profile in competitive artistic gymnastics girls: Comparison with non-gymnasts

Abstract

Objective: To identify the physical potentialities, through dermatoglyphic profiles, of competitive gymnast girls compared to non-gymnast girls.

Method: Non-gymnast girls (n = 50) and gymnast girls (n = 50) participating in the 2018 Regional Base Championship, Zone 1 North of Mexico, of the states of Sonora, Sinaloa, Baja California, Baja California Sur and Chihuahua The above through the computerized dermatoglyphic method, on the basis of the protocol proposed by Cummins and Midlo, which consists of making the fingerprints of the 10 fingers.

Results: Gymnasts exhibit greater motor coordination, agility and endurance, since they have higher values in fingerprints such as whorls and delta 10. Absolutely all the formulas found in gymnasts have whorls (coordination and agility), although in different proportions. The formulas that are repeated in both groups are loops > whorls (gymnasts 48% and not gymnasts 44%) and whorls > Loops (gymnasts 26% and non-gymnasts 16%). Noting that, although in non-gymnast girls such formulas also appear, in this group they tend to diversify clearly.

Conclusions: It is possible to define that whorls, which correlate with coordination and agility, are traces of the utmost importance in the gymnast's practice, which together with a delta 10 (average) of 14 and a high count of lines on the fingers of the left hand, as essential elements in the dermatoglyphic profile in gymnastics.
