Anthropometric and equipment characteristics in adolescent sprint kayakers
Los objetivos de este estudio fueron describir las caracter铆sticas antropom茅tricas y la configuraci贸n del material utilizado por 91 kayakistas espa帽oles adolescentes de 13 y 14 a帽os, de aguas tranquilas y buscar correlaciones entre ambas variables. Se valoraron las caracter铆sticas antropom茅tricas y las dimensiones del material de competici贸n de noventa y un kayakistas de aguas tranquilas (45 hombres y 46 mujeres), de 13 y 14 a帽os de edad. Los hombres kayakistas de 14 a帽os presentaron valores superiores a los de 13 a帽os en cuanto a dimensiones antropom茅tricas y del material de competici贸n, mientras que no se encontraron diferencias significativas entre las variables analizadas entre las mujeres kayakistas de 13 y 14 a帽os. La talla y envergadura presentaron las mayores correlaciones con la longitud de la pala y la distancia asiento - reposapi茅s. La informaci贸n aportada por este trabajo podr铆a ser de utilidad para ajustar las dimensiones del material de competici贸n, optimizando as铆 el confort y rendimiento en kayakistas j贸venes.The aims of this study were to describe kinanthropometric characteristics and equipment set-up of male and female young kayakers and to look for correlations between both variables. Ninety one young sprint kayakers (45 males and 46 females), aged 13 and 14 years old, were assessed using a battery of 12 anthropometric and 5 equipment dimensions. Comparison between the 13- and 14-year-old kayakers showed that 14-year-old males had greater body and equipment dimensions than their 13-year-old counterparts, whereas there were no significant differences between 13- and 14-year-old female kayakers in both anthropometric and equipment set-up dimensions. Stretch stature and arm span were the variables which greater coefficient correlations showed with total paddle length and seat - feet bar distance. The data presented in this paper may provide important information to adjust equipment sep-up in order to optimise comfort and performance in young kayakers
Sagittal spinal curvatures and pelvic inclination in kayakers
El objetivo del estudio fue comparar la disposici贸n sagital del raquis e inclinaci贸n p茅lvica en diferentes posiciones en kayakistas. A ciento treinta kayakistas entre 15 y 20 a帽os (62 varones y 68 mujeres) se les evalu贸, mediante un Spinal Mouse, la disposici贸n angular del raquis tor谩cico, lumbar e inclinaci贸n p茅lvica en bipedestaci贸n, sedentaci贸n relajada, m谩xima flexi贸n del tronco en sedentaci贸n, test sit-and-reach, posici贸n de base y de ataque en un kayak-erg贸metro. La cifosis tor谩cica en la piragua fue menor (p<0,001) que en bipedestaci贸n y sedentaci贸n relajada. El raquis lumbar se dispuso en inversi贸n lumbar en las posturas de flexi贸n del tronco y sedentaci贸n, favorecido por una posici贸n de retroversi贸n p茅lvica. Las mujeres adoptaron posturas de menor flexi贸n lumbar y p茅lvica en el kayak-erg贸metro. En conclusi贸n, la posici贸n de las mujeres en el kayak-erg贸metro se caracteriza por posturas m谩s alineadas del raquis y pelvisThe aim of this study was to compare the sagittal spinal curvatures and pelvic tilt in different positions on kayakers. One hundred and thirty kayakers between 15 and 20 years (62 males and 68 females) participated in this study. Thoracic and lumbar curvatures and pelvic position were evaluated with a Spinal Mouse system in standing position, slumped sitting, maximal trunk bending with knees flexed, sit-and-reach test, base position right entry position and left entry position in a kayak ergometer. Thoracic kyphosis in the kayak-ergometer was more reduced (p<0,001) than standing and slumped sitting. Lumbar spine adopted kyphotic postures when maximal trunk flexion was performed and in the kayak ergometer. This posture was related to posterior pelvic tilt. Females showed lower lumbar and pelvic flexion than males in the kayak ergometer. In conclusion, females adopt more aligned spinal and pelvic postures in the kayak ergometer than malesEste estudio se realiz贸 en el marco de las ayudas de la Fundaci贸n S茅neca-Agencia de Ciencia y Tecnolog铆a de la Regi贸n de Murcia (II PCTRM 2007-2010) al proyecto n潞 11951/PI/09, titulado 鈥淓volution of sagittal spinal curvatures, hamstring extensibility, low back pain, and anthropometric characteristics in elite paddlers
