Incidence injury analysis on rowers in the Spanish Mediterranean fixed bench championship 2012

The standardized assessment of sports injuries provides important epidemiological information and instructions to prevent them. The aim of this study was to determine if the pattern detrimental impact on fixed seat rowing agreed with the literature review of the Olympic rowing modality. A retrospective questionnaire was administer to 79 male rowers, with an age mean of 27.66 ± 7.15, belonging to the male in the senior category VIII Rowing Spanish Mediterranean Bank Fixed Championship that took place in Torrevieja during the 25th, 26th and 27th of May. The anatomical regions that were damage the most were the ankle (15.4%) and lower back (13.2%). These injuries have occurred with higher incidence in training (55.1%) as the most recidivist injury, the ankle, which has occurred for 73% of the time during this moment. The most common injury is the overuse (44.2%) and the most repeated diagnosis was sprain (23.1%).

The anthropometric profile of elite roller figure skaters

Although the anthropometric profiles of Olympic athletes, as a group, are well known, there is still a need for specific reference data for each sport given that each discipline has its own characteristics. This study has been designed considering the limited number of articles that focus on the anthropometric characteristics of artistic roller skating and, more specifically, the figures discipline. The aim of this study is twofold: firstly, to define the anthropometric profile, body composition and somatotype of male and female artistic roller figure skaters in order to establish specific profiles; and, secondly, to establish the differences between the anthropometric profiles, body compositions and somatotypes of male and female skaters. Twenty-nine professional roller skaters (male = 15, female = 14) underwent measurements of standard anthropometry (height, body mass, arm span, 8 skinfolds, 3 breadths and 11 girths). The somatotype was measured using the Heath-Carter methods. A T-Student test for independent samples was conducted in order to assess the differences between male and female skaters. Significant statistical differences were found between male and female skaters in terms of body mass, height, arm span, the sum of four and six skinfolds and all skinfold measurements. Male skaters have a BMI of 21.4± 1.6 and female skaters have a BMI of 21.5 ± 2.4. The results indicate that arm span is an important characteristic for skaters. Mesomorphy is the most important component, followed by endomorphy, for male and female skaters. Male skaters have an endomesomorphic somatotype (3.5-4.5-2.5) and female skaters have a balanced mesomorphic somatotype (3.3-4.1-2.9).

Performance Factors in Women's Team Handball: Physical and Physiological Aspects—A Review

Team handball is an Olympic sport played professionally in many European countries. Nevertheless, a scientific knowledge regarding women's elite team handball demands is limited. Thus, the purpose of this article was to review a series of studies (n = 33) on physical characteristics, physiological attributes, physical attributes, throwing velocity, and on-court performances of women's team handball players. Such empirical and practical information is essential to design and implement successful short-term and long-term training programs for women's team handball players. Our review revealed that (a) players that have a higher skill level are taller and have a higher fat-free mass; (b) players who are more aerobically resistant are at an advantage in international level women team handball; (c) strength and power exercises should be emphasized in conditioning programs, because they are associated with both sprint performance and throwing velocity; (d) speed drills should also be implemented in conditioning programs but after a decrease in physical training volume; (e) a time-motion analysis is an effective method of quantifying the demands of team handball and provides a conceptual framework for the specific physical preparation of players. According to our results, there are only few studies on on-court performance and time-motion analysis for women's team handball players, especially concerning acceleration profiles. More studies are needed to examine the effectiveness of different training programs of women's team handball players' physiological and physical attributes.

Efectos de los aminoácidos ramificados en deportes de larga duración: revisión bibliográfica

Introducción: El informe emitido por la Agencia Europea de Seguridad Alimentaria (EFSA) en 2010 sobre las declaraciones nutricionales y propiedades saludables, muestra que no existen evidencias científicas que apoyen la suplementación con aminoácidos ramificados (BCAAs). El objetivo de este estudio es analizar los efectos del consumo de suplementos de BCAAs en deportes de larga duración (DLD). Métodos: Estudio descriptivo de revisión bibliográfica sobre el estado actual del efecto del consumo de suplementos de BCAAs. Se realizó una búsqueda en la base de datos PubMed y estrategia de bola de nieve. Criterios de inclusión: Estudios realizados en humanos, ensayos clínicos controlados aleatorizados (ECCA) en castellano/inglés relacionados con el consumo de BCAAs, leucina, valina e isoleucina en DLD y sus efectos sobre el daño muscular, rendimiento deportivo, fatiga central, respuesta anabólica y sistema inmunológico publicados en cualquier país hasta mayo 2014. Resultados: De los 330 estudios identificados, 14 cumplieron los criterios de inclusión. La media de sujetos participantes en los estudio es igual a (11,36 ± 7,43). Sólo dos estudios incluyen un grupo de mujeres. Las disciplinas deportivas que se encontraron en los estudios fueron carrera a pie, ciclismo, combinación ciclismo y carrera a pie, triatlón distancia olímpica y un estudio que incluía 2 grupos de deportistas (triatlón distancia olímpica y carrera a pie). Se estudian los efectos de los BCAAs y daño muscular, rendimiento deportivo, fatiga central, respuesta anabólica en periodo de recuperación y respuesta inmunológica en periodos diferentes del entrenamiento: antes, durante y después o una combinación de éstos. Discusión: Se observa que existe un menor grado de dolor y daño muscular, menor percepción del esfuerzo y fatiga mental, mayor respuesta anabólica en periodo de recuperación y mejora de la respuesta inmunológica cuando se suplementa con BCAAs, no obstante su toma antes o durante la actividad física no mejora el rendimiento deportivo. No se ha encontrado consenso en la dosis y cronología de la toma más eficaz, aunque es más efectivo si hay una relación 2-3/1/1g, entre los aminoácidos Leucina/ Isoleucina y Valina.
