Salvamento acuático : guía del alumno

El manual que tienes en tus manos pretende mostrar de forma gráfica y accesible los fundamentos básicos del salvamento acuático: dar a conocer las cuestiones de seguridad en las zonas de baño y deporte acuático, los recursos humanos necesarios para que esa seguridad sea posible, los materiales y las técnicas de rescate y las formas precisas de actuar ante accidentes graves. Con este libro se intenta que la labor del socorrista sea eficaz y segura en todo memento. La didáctica que contiene va encaminada no sólo a inculcar unos contenidos y unas técnicas concretas, sino también unas prácticas y entrenamientos de esas técnicas para perfeccionar las labores de salvamento. Es por ello que este manual resulta altamente aconsejable para todo profesional de la actividad física y el deporte, en especial si su trabajo está relacionado con algún deporte acuático.Actividad Física y Deport

Evaluation of swim fins according to the time taken in swim tests and manikin tow tests

El objetivo del presente trabajo fue investigar los efectos de utilizar diferentes tipos de aletas sobre el tiempo de nado con y sin maniquí. Participaron en este estudio 13 sujetos, todos ellos varones, con una edad media de 22,9 ± 0,8 años, un peso de 74,5 ± 8,7 kg. y una altura de 175,7 ± 6,8 cm. Los sujetos realizaron dos pruebas de 50 m de distancia, una de nado y otra de remolque. Ambas pruebas se realizaron sin utilizar aletas, con aletas blandas, cortas, duras y de fibra, en orden aleatorio y con un descanso mínimo de 30 minutos entre una modalidad y otra. Los resultados mostraron que no existen diferencias significativas entre utilizar aletas y no en la prueba de 50 m nado, y sí existen para la prueba de 50 m remolque. También se observó que las aletas de tipo duro contribuyeron a una mayor velocidad en las pruebas de nado y remolque. En todos los casos se apreció el efecto de la fatiga en la segunda parte de la prueba, siendo significativa en la prueba de 50 m remolque.Actividad Física y Deport

Water polo throwing speed and body composition: an analysis by playing positions and opposition level

The aim of this study was to develop an anthropometric profile on highly skilled male water polo players by specific playing positions. Also, to identify significant relationships between these features an overhead throwing speed in highly skilled male Water Polo players by specific playing positions. Methods: A total of 94 male water polo players (24.5±5.3 yrs) who were playing in the Spanish King´s cup were studied. Subjects were grouped according to their specific playing positions: 15 goalkeepers, 45 offensive wings, 20 center backs and 14 center forwards. Anthropometric assessment was made following ISAK protocols. Hand grip and throwing speed in several situations were also assessed. A one-way analysis of variance (ANOVA) was used to determine if significant differences existed among the four playing positions. Pearson product-moment correlation coefficients (r) were used to determine the relationships of all anthropometric measures with throwing speed and hand grip. The total player’s somatotype was endomorphic-mesomorphic (2.9–5.8–2.3). Center forwards exhibit important anthropometric differences compared with the other specific playing positions in elite male water polo players, but no differences were found in throwing speed by specific playing positions in each throwing conditions. Moreover, a higher number of relationships between anthropometric and throwing speed were found in wings and also in center backs but no relationships were found in center forwards. The data reflects the importance of muscle mass and upper body in the throwing skill. Coaches can use this information in order to select players for the different specific positions

Analysis of rescues in a water park

Los parques acuáticos son lugares donde se prevé que pueden ocurrir accidentes que, al estar en contacto con el medio acuático, terminen en ahogamiento. El presente estudio trata de analizar los rescates acuáticos que ocurren en los parques acuáticos. Este estudio se ha llevado a cabo con una muestra de 79 intervenciones reales registradas en dos parques acuáticos de Morey’s Pier (Nueva Jersey, EE.UU.). El 48,10% (38) son mujeres y el 51,90% (41) hombres, con una edad media de 17,29±11,48 y 10,02±5,28 años respectivamente. La variable dependiente objeto de estudio fue conocer los rescates realizados en los parques acuáticos. Las variables independientes son: 1) género y 2) edad de las víctimas. Para el estudio se ha llevado a cabo un análisis descriptivo e inferencial de las variables de estudio, verificando la normalidad y la homogeneidad y buscando las diferencias significativas mediante la prueba de Chicuadrado. Destacamos como conclusiones del trabajo que 1) se realizaron un mayor número de intervenciones acuáticas a la población que tenía una edad entre 7 y 12 años, 2) el 77,21% de las víctimas tiene una edad inferior a los 20 años, 3) se encuentra una mayor tendencia al accidente acuático cuando la víctima es varón menor de 7 años y mujer mayor de 20 años.Actividad Física y Deport

Predicting playing status in professional water polo players: analysis by gender

BACKGROUND: The aim of this study was twofold: firstly, to identify the characteristics of water polo players that discriminate between women and men based on specific playing positions; and secondly to develop a predicting model to identify the characteristics that are best suited to a given playing position based on gender. METHODS: The study included 130 professional water polo players. Anthropometric characteristics and throwing velocity were analyzed in different situations: no defender or goalkeeper, goalkeeper only and the players made three rapid arm movements and then threw the ball at maximum speed without further feinting with goalkeeper. Measured variables were compared according to gender and player position using discriminant analysis. RESULTS: The predictive model accurately classifies 71.1% of the male players using three variables (arm span, muscle mass Lee and penalty without goalkeeper), and 64.7% of the female players using three variables (triceps skinfold, biceps skinfold and anteroposterior chest breadth). CONCLUSIONS: The anthropometric characteristics and throwing velocity play an important role in identifying the different specific positions in male and female water polo players. In female players, the variables that were determinant in the predictive model, were those associated with body composition.Ministerio de Ciencia e Innovación | Ref. DEP2008-0611

Influence of Physical Aspects And Throwing Velocity in Opposition Situations in Top-Elite and Elite Female Handball Players

The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student’s t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were non-modifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations
