Introduction:

The scientific community of taekwondo has made efforts to optimize the talent selection system, but they have failed to enhance the genetic indicators that cannot be changed with sports training.

Aim:

To design the ratio profile as an indicator during the detection of the genetic potential of taekwondo talents.

Materials and methods:

the population comprised the Cuban female selection. Theoretical and analytical-synthetic, inductive-deductive methods were used, in addition to measurements. The statistical and mathematical methods were included, then, the central trend measurements, and the correlation coefficient were determined.

Results:

The biological indicators or markers that provide information about the genetic potential, and to differentiate the physical components include the fingerlength ratio.

Conclusions:

the ratio profile can be used to detect talents during the selection process, which the users considered a viable proposal.
