Dermatoglyphics and analysis of the Alpha-Actinin-3 gene are evaluative instruments frequently used to identify the sportive and general population profile associated with physical performance. This research aimed to determine, based on dermatoglyphic characteristics and the R577X polymorphism of Alpha-Actinin-3, the percentage of people in the State of Paraíba/Brazil, with unfavorable characteristics to excelling in sports that require anaerobic power. A descriptive study of profiles, with ex post facto typology, was performed. The dermatoglyphic fingerprint characteristics of 309 people (149 males and 160 females) were identified, and ACTN3 genotype was analyzed in 96 people (40 males and 56 females). The dermatoglyphic data indicated that 5.8% of the study population fit the classification of anaerobic muscle power predisposition, while 94.2% did not fit on it. The genetic frequency analysis indicated that 19.8% of subjects in the sample had the XX mutant genotype. These results represent a substantial error reduction in the search for and selection of athletes with the potential for high performance, especially in those sports that require AMP.
