Abstract: the aim of this study was to determine the sagittal spinal morphology of thoracic and lumbar spine in young kayakers. a total of 66 young sprint kayakers, 36 males and 30 females (mean age: 16,22 ± 0,80) participated in the study. sagittal spinal curvatures of thoracic and lumbar spine in standing, lying prone and maximal trunk flexion with knees extended (sit-and-reach test) were measured with a spinal mouse. thoracic kyphosis was higher in males than in females in all three analyzed postures, although greater differences were found in the sit-and-reach test. the frequency of thoracic hyperkyphosis was higher in males (42.1%) than in females (21.4%). the angular values when lying prone were more reduced than in standing (p < 0.001). paddlers with thoracic kyperkyphosis showed a reduced thoracic angle when lying prone (37.85 ± 9.42) than in standing (50.95 ± 5.12). no significant differences between sexes were found in the lumbar curve. a predominance of neutral angular values was found in the lumbar curve (81.6% in males and 75.0% in females). in conclusion, the sagittal spinal morphology showed a trend toward thoracic hyperkyphosis in junior kayakers, specially in males. however, these curves were non-structural deformities. lumbar spine showed a high percentage of neutral values. kayak training is associated to improved lumbar intervertebral flexion and increased lumbar hyperkyphotic postures. it is necessary to include postural training to improve the spinal morphology of young paddlers.

Abstract: El objetivo de este trabajo fue describir y comparar las características antropométricas, maduración, somatotipo y proporcionalidad de mujeres kayakistas de aguas tranquilas y slalom. Cincuenta palistas de 13 a 14 a os de edad (26 de aguas tranquilas y 24 de slalom), fueron valoradas usando una batería de 29 medidas antropométricas. Se calculó el porcentaje de grasa, el somatotipo, los valores Z utilizando la estrategia Phantom de proporcionalidad y la maduración expresada como los a os hasta/desde la edad de máxima velocidad de crecimiento en altura. Las palistas de aguas tranquilas se caracterizaron por una mayor talla y talla sentado que las de slalom, lo que podría interpretarse como un mayor desarrollo madurativo de las primeras. Los valores de proporcionalidad fueron similares en la mayoría de las variables analizadas. Ambos grupos de kayakistas presentaron un somatotipo medio clasificado como mesomorfo endomorfo, siendo las palistas de slalom las que presentaron un somatotipo más heterogéneo. La información aportada en este estudio puede ser utilizada como guía en el proceso de detección de talentos en mujeres kayakistas de aguas tranquilas y slalom.

Abstract: El objetivo fue valorar la morfología raquídea del raquis torácico y lumbar en piragüistas de la modalidad de kayak de categoría cadete. A un total de 66 kayakistas de aguas tranquilas, 36 varones y 30 mujeres de categoría cadete (media de edad 16,22 ± 0,80 a os), se les evaluó mediante un Spinal Mouse la morfología sagital del raquis torácico y lumbar en bipedestación, decúbito prono y en flexión máxima del tronco en sedentación con rodillas extendidas (test sit-and-reach). La cifosis torácica en los varones fue superior en las tres posiciones analizadas, especialmente en el test sit-and-reach. El porcentaje de casos con hipercifosis torácica fue de un 42,1% en los varones y un 21,4% en las mujeres. Los valores angulares en decúbito prono fueron inferiores que en bipedestación (p < 0,001). Aquellos deportistas con hipercifosis torácica tenían un valor angular menor en decúbito prono (37,85 ± 9,42) que en bipedestación (50,95 ± 5,12). En la curva lumbar no se encontraron diferencias entre géneros en las posiciones evaluadas. En el raquis lumbar, predominaron las angulaciones consideradas normales (81,6% en varones y 75% en mujeres). En conclusión, la morfología sagital del raquis en kayakistas de categoría cadete se caracteriza por una tendencia a la hipercifosis torácica, especialmente en los varones, si bien se trata de curvas no estructuradas. En cuanto a la curva lumbar en bipedestación presenta un alto porcentaje de ángulos considerados normales. La práctica del piragüismo/canotaje de aguas tranquilas en su modalidad de kayak genera una mayor capacidad de flexión intervertebral lumbar, que produce un alto porcentaje de morfotipos cifóticos. Es preciso adoptar medidas de intervención postural para mejorar la morfología raquídea de los palistas de aguas tranquilas. The aim of this study was to determine the sagittal spinal morphology of thoracic and lumbar spine in young kayakers. A total of 66 young sprint kayakers, 36 males and 30 females (mean age: 16,22 ± 0,80) participated in the study. Sagittal spinal curvatures of thoracic and lumbar spine in standing, lying prone and maximal trunk flexion with knees extended (sit-and-reach test) were measured with a Spinal Mouse. Thoracic kyphosis was higher in males than in females in all three analyzed postures, although greater differences were found in the sit-and-reach test. The frequency of thoracic hyperkyphosis was higher in males (42.1%) than in females (21.4%). The angular values when lying prone were more reduced than in standing (p < 0.001). Paddlers with thoracic kyperkyphosis showed a reduced th

Abstract: El objetivo principal del estudio fue determinar la morfología del raquis e inclinación pélvica en bipedestación en tres grupos de ciclistas de distintas edades, con un volumen de entrenamiento y experiencia similares. Un total de 65 ciclistas fueron divididos en tres grupos de edad: grupo 1 ( 30 a os; n = 20); grupo 2 (entre 31 y 40 a os; n = 25); y grupo 3 ( 41 a os; n = 20). Posteriormente se les evaluó la morfología sagital del raquis torácico, lumbar e inclinación pélvica en bipedestación, mediante el sistema Spinal Mouse. Los valores angulares medios para el raquis torácico, lumbar e inclinación pélvica para el grupo 1 fueron: 46,60 ± 10,09; - 26,40 ± 7,17; 13,20 ± 4,94; para el grupo 2: 47,64 ± 8,58; -26,92 ± 6,34; 12,24 ± 4,45; y para el grupo 3: 50,75 ± 12,77; -20,70 ± 10,10 y 8,15 ± 8,21. Se encontraron diferencias significativas en el raquis lumbar e inclinación pélvica en los grupos 1 y 2, con respecto al 3. En conclusión, la edad es un factor que condiciona la morfología del raquis e inclinación pélvica en ciclistas que presentan los mismos a os de práctica y volumen de entrenamiento en ciclismo. The aim of this study was to evaluate the sagittal spinal morphology and pelvic tilt in standing in three different age-group cyclists who had the same cycling experience and training volume. A total of 65 cyclists were divided in three age-groups: group 1: ( 30 years old; n = 20); group 2 (between 31 y 40 years old; n = 25); and group 3 ( 41 years old; n = 20). The Spinal Mouse was used to measure sagittal thoracic and lumbar spine and pelvic tilt in standing on the floor. The mean values for thoracic and lumbar spine and pelvic tilt were: group 1, 46.60 ± 10.09; - 26.40 ± 7.17; 13.20 ± 4.94; group 2, 47.64 ± 8.58; -26.92 ± 6.34; 12.24 ± 4.45; and group 3, 50.75 ± 12.77; -20.70 ± 10.10 y 8.15 ± 8.21, respectively. Significant differences were found for the lumbar spine and pelvic tilt in the groups 1 and 2 with respect to group 3. In conclusion, aging is a conditional factor to the sagittal spinal morphology and pelvic tilt in cyclists who present the same years of experience and training volume in cycling.

Abstract: El objetivo principal del estudio fue valorar la disposición sagital del raquis torácico y lumbar en bipedestación y sobre la bicicleta, en ciclistas de la categoría máster 40. Un total de 50 ciclistas máster 40 (media de edad: 44,02±2,51 a os) fueron evaluados mediante el sistema Spinal Mouse en bipedestación y sobre la bicicleta en tres agarres del manillar: transversal, de manetas y bajo. En bipedestación, los valores angulares medios para el raquis torácico y lumbar fueron de 49,42±9,00 y -22,74±9,38, respectivamente. Un elevado porcentaje de los ciclistas (68%) presentaron una hipercifosis torácica, mientras que la mayoría tenían valores normales en la lordosis lumbar. Sobre la bicicleta, los ciclistas mostraron una reducción significativa de la cifosis torácica con respecto a la bipedestación, mientras que el raquis lumbar se disponía en una postura de inversión. En conclusión, la frecuente hipercifosis torácica en bipedestación de los ciclistas de la categoría máster 40 no está relacionada directamente con la postura adoptada sobre la bicicleta. The aim of this study was to determine the sagittal spinal morphology of thoracic and lumbar spine in relaxed standing and sitting on the bycicle in master 40 cyclists. A total of 50 master 40 male cyclists (mean age: 44.02 ± 2.51 years) were evaluated. The Spinal Mouse system was used to measure the sagittal thoracic and lumbar curve in standing and sitting on the bicycle at three different handlebar-hand positions (high, medium, and low). The values for thoracic and lumbar curvatures in standing were 49.42 ± 9.00 and -22.74 ± 9.38, respectively. A high frecuency of thoracic hyperkyphosis in standing was observed (68%). When sitting on the bicycle the thoracic curve showed lower angles in the three handlebar.hand positions that in standing. The lumbar curve adopted a kyphotic posture. The standing thoracic hyperkyphosis in master 40 cyclists may be related to other factors than the posture adopted on the bicycle.

Abstract: Los objetivos de este trabajo fueron describir las características antropométricas de hombres canoístas de categoría cadete y comparar su somatotipo y proporcionalidad con palistas olímpicos. Treinta y tres canoístas de 15 a 16 a os de edad, fueron valorados usando una batería de 41 medidas antropométricas. Se calculó la composición corporal, el somatotipo y los valores Z utilizando la estrategia Phantom de proporcionalidad. El somatotipo medio de los canoístas obtuvo la clasificación de mesomorfo balanceado. De la comparación con los palistas de categoría olímpica, destacó la menor mesomorfia así como los valores inferiores de proporcionalidad en los perímetros y diámetros del tronco de las extremidades superiores de los canoístas cadetes. La información aportada en este estudio puede ser utilizada como guía en el proceso de detección de talentos en canoístas jóvenes de aguas tranquilas. The aim of this study was to describe kinanthropometric characteristics of young male sprint canoeists and to compare their somatotype and proportionality with Olympic paddlers. Thirty three young sprint canoeists, aged 15 and 16 years old, were assessed using a battery of 41 anthropometric dimensions. Body composition, somatotypes and Phantom Z-scores were calculated. Mean somatotype of male canoeists was best described as balanced mesomorphy. Young canoeists had lower ratings of mesomorphy and lower proportional dimensions in upper body girths and breadths than Olympic paddlers. The data provided in this study could be used as a guideline for talent identification in sprint canoeing.
