International Journal of Morphology , 2012,
Abstract: El objetivo de este estudio fue describir las características de los índices antropométricos en canoístas de categoría cadete. A un total de 33 canoístas se les valoró peso, talla, envergadura, talla sentado, perímetros de la cintura y cadera, longitudes del brazo y antebrazo, así como diámetros biacromial y biileocrestal. Se calculó el índice de masa corporal (IMC), ratio cintura-cadera, envergadura relativa e índices córmico, de Manouvrier, acromio-iliaco y braquial. La mayor parte de los canoístas de categoría cadete obtuvieron valores propios de normopeso respecto al IMC, valores bajos de ratio cintura-cadera y una envergadura mayor que la altura. Existe una mayor variedad respecto al resto de índices estudiados, dándose un mayor número de casos de tronco medio para el índice córmico, extremidades inferiores largas para el índice de Manuovrier, tronco trapezoidal e intermedio para el índice acromio-iliaco y antebrazo medio y corto para el índice braquial. The objective of this study was to describe the characteristics of the anthropometric indexes in male young sprint canoeists. Body mass, stature, sitting height, arm spam, waist and hip girths, arm and forearm lengths and biacromial and biiliocristal breaths were measured in the 33 canoeists. Anthropometric indexes were obtained: body mass index, waist-hip ratio, relative arm spam and cormic, Manouvrier's, acromial-iliac and brachial indexes. Most paddlers had a healthy weight for height, a low waist-hip ratio, and a higher arm span than stretch stature. Results were more varied in other indexes, with a higher number of paddlers who had intermediate trunk length for Cormic index, long lower limbs for Manouvrier index, intermediate an trapezoidal trunk shape for acromial-iliac index and a medium and short forearm length for brachial index.

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.

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 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.

International Journal of Morphology , 2011,
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.

Abstract: the objective of this study was to determine the influence of hamstring extensibility in sagittal spinal curvatures and pelvic inclination on young athletes. methods: a hundred and fifty-two young athletes (mean age: 16.22 ± 0.80 years) were recruited. thoracic and lumbar curvatures and pelvic inclination were evaluated with a spinal mouse system in the sit-and-reach test, toe-touch test and mcrae & wright test. hamstring muscle extensibility was determined by passive straight leg raise test (pslr). the sample was divided into three groups with regard to straight leg raise angle (group a: pslr < 76, n=49; group b, pslr between 76-88, n=45; and group c, pslr > 88, n=50). results. athletes with lower extensibility presented higher thoracic angle and a more posterior pelvic tilt in the sit-and-reach and toe-touch tests. however, no significant differences were found between groups when maximal trunk flexion with knees flexed was performed (mcrae & wright test). the lumbar curve was not affected by hamstring extensibility in any position. conclusions: lower hamstring extensibility is related to increased thoracic curve and more posterior pelvic tilt when maximal trunk flexion with knees extended is performed. hamstring extensibility has not any influence in sagittal lumbar morphology when trunk flexion is performed.
