Métodos: La muestra estuvo compuesta por 33 deportistas varones jóvenes de edad (17,03 ±  0,94 años). La composición corporal y el somatotipo se obtuvieron a partir de medidas antropométricas de diámetros, perímetros y pliegues cutáneos. El equilibrio postural dinámico se midió con la prueba de equilibrio de excursión en estrella modificada (mSEBT) en las direcciones anterior, posteromedial y posterolateral. Se utilizó la prueba de correlación de Pearson para identificar la relación entre las variables de composición corporal y somatotipo con el equilibrio postural dinámico de los atletas. Resultados: En el miembro inferior dominante, la composición corporal mostró correlaciones significativas para la dirección anterior del mSEBT con masa adiposa (r=-0,741; p=0,001), masa muscular (r=0,662; p=0,009), endomorfo (r= -0,822; p=0,009) y ectomorfo (r=0,790; p=0,002). La masa adiposa también mostró relaciones significativas con la dirección posteromedial (r=-0,413; p=0,037) y posterolateral de mSEBT (r=-0,291; p=0,041). En el miembro inferior no dominante, en la dirección anterior del mSEBT, hubo una correlación significativa con la masa adiposa (r=-0,691; p=0,009), masa muscular (r=0,472; p=0,025), endomorfo ( r=-0,778; p=0,001) y ectomorfo (r=0,843; p=0,001) somatotipos.

Objective: The aim of this study was to determine the relationship between body composition and somatotype with dynamic postural balance in young basketball players. Methods: The sample included 33 young male athletes aged (17.03 ± 0.94 years old). Body composition and somatotype were obtained from anthropometric measurements of diameters, perimeters, and skinfolds. Dynamic postural balance was measured with the modified star excursion balance test (mSEBT) in anterior, posteromedial, and posterolateral directions. The Pearson correlation test was used to identify the relationship between body composition and somatotype variables with the dynamic postural balance of the athletes. Results: In the dominant lower limb, body composition showed significant correlations for the anterior direction of the mSEBT with adipose mass (r=-0.741; p=0.001), muscle mass (r=0.662; p=0.009), endomorph (r=-0.822; p=0.009) and ectomorph (r=0.790; p=0.002).

The use of a smaller number of contacts in attacks initiated in the opposite field, and a greater number of contacts in attacks initiated in one's own field, favors the creation of goal opportunities. Playing fields with dimensions similar to the most familiar one favor a greater number of contacts with the ball and increased effective time of play.

This study compared the effect of two periodization models, the classic Matveev model is modified (CMm) and the ATR during 24 weeks on the rightward shift of the lactate curve (CVL) and swimming speed (SS) (m·s), through of quasi-experimental research, CMm (n = 15) (16.00 ± .54 years; 1.65 ± .12 m; 55.00 ± 8.56 kg) and ATR (n = 15) (16.00 ± .44 years; 1.73 ± .05 m; 58.00 ± 4.28kg). For the lactate blood testing concentrations (CLS) [mmol/L], the Biosen S-Line Sports equipment, and the progressive load test of 4x400 m in the free-swimming technique was used. Differences were found between the groups in VN (m s) in all functional areas (AFS) (Effect size (TE) RI TE = 1.5, p = .03; RII TE = 1.6, p = .03; MVO2 ES= 1.6, p = .04; RC ES= 1.5, p = .04), no differences were found (p > .05) in the displacement of CVL between groups. Despite of the absence of significant differences in CVL, an improvement in SS was observed, it shows that swimmers were able to develop a greater SS without increasing CLS, denoting an increase in their aerobic capacity, which implies that both models have the potential to shift CVL to the right and to improve SS despite methodological differences in these models.\u0000Keywords: lactate curve; periodization model; Matveyev; ATR; swimming.\u0000 \u0000 \u0000 ","PeriodicalId":52896,"journal":{"name":"Retos de la Direccion","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76975105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
