Asociación entre variables de empuje Isométrico de media pierna (EIMP) con variables antropométricas y cualidades físicas en jugadores varones de Rugby Amateurs / Relationships between Isometric Mid-Thigh pull with anthropometric variables and physical qualities in Amateur Rugby players / Relações entre a puxada isométrica do meio da coxa com variáveis antropométricas e qualidades físicas em jogadores amadores de rugby

Objetivo: el objetivo de este estudio es describir el perfil de las variables del EIMP entre las dos posiciones de juego y determinar las posibles asociaciones con las características antropométricas y las cualidades físicas de un grupo de jugadores Rugby amateurs chilenos. Hipótesis: es por eso por lo que podemos plantear como hipótesis la existencia de asociaciones entre las variables de EIMP y las cualidades físicas de los jugadores de RU. Diseño metodológico: este estudio tiene un diseño de cohorte observacional, descriptivo y correlacional. Se investigó la asociación existente entre las variables de EIMP con las pruebas físicas y las variables antropométricas. Fueron evaluados treinta y dos jugadores de rugby varones de nivel amateurs chilenos (promedio ( DE, edad, 23,3 ( 5,4 años). Resultados: para la variable Masa Muscular se encontraron asociaciones grandes (r = 0.53) (p = 0.001) con la FM y asociaciones moderadas (r = 0,48) (r = 0,47) (r = 0,44) (r = 0,46) con F50, F100, F150 y F200 respectivamente. También se pueden observar las asociaciones grandes (R2 = 0,305) (R2 = 0,297) (R2 = 0,267) entre 1RM PB y F200, F100 y F150, respectivamente. Conclusión: en conclusión, este estudio puede demostrar la existencia de asociaciones estadísticamente significativas entre algunas de las variables antropométricas y físicos con las variables de Fuerza de EIMP en jugadores de RU amateurs chilenos.

OBJECTIVE: The objective of this study is to describe the profile of the EIMP variables between two playing positions and to determine its possible associations with anthropometric characteristics and physical qualities of a group of Chilean amateur rugby players. HYPOTHESIS: There are associations between the EIMP variables and the physical qualities of UR players. METHODOLOGICAL DESIGN: This study has an observational, descriptive and correlational cohort design. The association between the EIMP variables, from the physical tests, and the anthropometric variables was investigated. Thirty-two Chilean amateur-level male rugby players were evaluated (mean ( SD, age, 23.3 ( 5.4 years). RESULTS: For the Muscle Mass variable, large associations were found (r=0.53) (p=0.001) to FM, and moderate associations (r=0.48) (r=0.47) (r=0.44) (r =0.46) to F50, F100, F150, and F200 respectively. Large associations (R2=0.305) (R2=0.297) (R2=0.267) between 1RM PB and F200, F100, and F150, respectively, can also be observed. CONCLUSION: In conclusion, this study can demonstrate the existence of statistically significant associations between some of the anthropometric and physical variables and the EIMP Strength variables in Chilean amateur UR players.

OBJETIVO: O objetivo deste estudo é descrever o perfil das variáveis EIMP entre as duas posições de jogo e determinar as possíveis associações com as características antropométricas e qualidades físicas de um grupo de jogadores amadores de rugby chilenos. HIPÓTESE: É por isso que podemos hipotetizar a existência de associações entre as variáveis do EIMP e as qualidades físicas dos jogadores do RU. DESENHO METODOLÓGICO: Este estudo tem um desenho de coorte observacional, descritivo e correlacional. Investigou-se a associação entre as variáveis do EIMP com os testes físicos e as variáveis antropométricas. Trinta e dois jogadores de rugby masculinos de nível amador chileno foram avaliados (média ( DP, idade, 23,3 ( 5,4 anos). RESULTADOS: Para a variável Massa Muscular foram encontradas grandes associações (r=0,53ejercicio y cualidades físicos) (r=0,47) (r=0,44) (r=0,46) com F50, F100, F150 e F200 respectivamente. Grandes associações (R2=0,305) (R2=0,297) (R2=0,267) entre 1RM PB e F200, F100 e F150 respebaloncestotambém podem ser observadas. CONCLUSÃO: Em conclusão, este estudo pode demonstrar a existência de associações estatisticamente significativas entre algumas das variáveis antropométricas e físicas com as variáveis EIMP Força em jogadores amadores do RU chilenos.

The women inclusion on rugby: perceptions of Brazilian national team players

Aims: Women participation in sport is historically permeated by manifestations of discrimination, especially in male preserve practices. This study aimed to investigate and describe the processes of entry and performance of women athletes in rugby, as well as socio-cultural components of this field in relation to gender differences from the perspective of Brazilian women national senior team players. Methods: Semi-structured interviews with five athletes were performed and data analyzed based on the Grounded Theory method. Results: It was found that there are social barriers for women practice in rugby. By the other hand, better opportunities for the development of an athletic career are more available than in the past. Besides that, it has been perceived that the women players need to constantly prove that they can play hard to legitimize their athletic skills among men players. Conclusions: Even if the women participation in rugby is in a changing process of acceptance, barriers still need to be broken for a full social legitimation of these players' practice.(AU)
