Resumen

ESPINOZA-NAVARRO, O et al. Anthropometric Characteristics, Body Composition and Somatotype of Elite Pan-American Race Walking 20K. Int. J. Morphol. [online]. 2019, vol.37, n.4, pp.1220-1225. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022019000401220.

The anthropometric and somatotype evaluation is an essential tool in the selection and control of high-performance athletes. The aim of this study was to describe the somatotype and body composition of male elite race walkers (20 k modality), and its relationship with athletic performance. Twenty-four race walkers participated in this study. The sample was divided into two groups: the race walkers with the best performance (upper 25 percentile; n=7) and the second group (n=17) that corresponds to the rest of the participants. Weight (kg), height (cm), seven skinfolds, two diameters and five perimeters were measured. Body fat percentage (BF%) were estimated with the Yuhasz formula, and the somatotype was used applying the Heath-Carter method. The best performing athletes were taller (178.3 ± 4.4 cm vs. 173.7 ± 5.6 cm, p <0.05) and showed a greater ectomorphic component (p<0.05) than the rest of the participants. The somatotype of the best performance athletes was 2.2-2.8-4.1 against the 2.5-3.8-2.9 of the lowest performing athletes. The average time (hours, minute, seconds) of execution of the race in athletes of better performances was 1:22:40, in comparison with the athletes of lower performances with 1:32:41 (p<0.02). The ectomorphic component and height are morphological characteristics that can determine athletic performance of race walkers. It is suggested to consider these factors in the selection of the race walkers.
