ABSTRACT
Background and objectives:
Athletes from combat sports are grouped into a series of weight categories that are intended to promote fair competition. Differences in performance are partly attributable to differences in body size. Consequently, ratio standards in which a performance variable is simply divided by an anthropometric characteristic such as body mass are often used, although this application is not recommended. This study aimed to obtain allometric models to interpret Wingate Anaerobic Test (WAnT) outputs among male adult athletes from combat sports. Materials andMethods:
The sample was composed of 64 participants aged 18-39 years (24.2 ± 4.6 years). Stature and body mass (BM) were measured and air displacement plethysmography used to estimate fat mass and fat-free mass (FFM). Lower-limb lean soft tissue (LL-LST) was derived from dual energy X-ray absorptiometry. WAnT outputs were peak power (WAnT-PP) and mean power (WAnT-MP). Allometric models were obtained from simple and multiple linear regressions using log-transformed variables.Results:
Models derived from a single three-dimension descriptor explained a large portion of variance WAnT-PP (BM 31.1%; FFM 54%; LL-LST 47.2%) and WAnT-MP (BM 50.1%; FFM 57.4%; LL-LST 62.7%). Finally, the best proportional allometric models emerged from the combination of LL-LST and FFM (WAnT-PP 55%; WAnT-MP 65%).Conclusions:
The relationship between weight categories and performance did not seem to be explained by the basic principles of geometric similarity.Palavras-chave
