ABSTRACT

Lifeguards are the first responders to any type of aquatic incident, including rapid rescue situations such as boating and sporting accidents, animal bites/attacks, and cases involving massive bleeding. In their line of work, rescue boats such as Rescue Water Craft (RWC) are commonly utilized the aim of this study is to evaluate the time and technique of placing a tourniquet on the sled of an RWC navigating at full speed. METHODS: A randomized crossover study design was used with a sample of 44 lifeguards. The inclusion criteria required that participants be certified lifeguards with experience in RWC operations and possess knowledge of responding to massive bleeding. Two CAT tourniquet placement tests were performed. In the 1) Beach-Tourniquet (B-TQ) test: it was performed on land and in the 2) Rescue Water Craft-tourniquet (RWC-TQ) test, sailing at a cruising speed of 20 knots. The evaluation was recorded in a checklist on the steps and timing of the correct application TQ by direct observation by an expert instructor. RESULTS: The tourniquet placement on RWC was an average of 11 s slower than when placed on the beach (BT-TQ 35.7 ± 8.0 vs. 46.1 ± 10.9 s, p > 0.001). In the percentage analysis of the results on correct execution of the skills, higher values are obtained for the B-TQ test than in RWC-TQ in Distance to the wound (into 5-7 cm), band adjustment, checking the radial pulse and reporting the time of tourniquet placement (p > 0.005). CONCLUSION: The placement of a tourniquet on a RWC navigating at 20 knots is feasible, relatively quick, and technically well executed.

ABSTRACT

En el año 2006 entró en vigor la normativa que actualmente regula la formación de socorristas en la Comunidad Autónoma de Madrid (España). El objetivo de este estudio es conocer la influencia de la aplicación de esta normativa sobre el porcentaje de aspirantes que obtiene el diploma de socorrista acuático y sobre su nivel de competencia en el agua. Para ello, se han analizado las marcas de tiempo acreditadas por 6.105 aspirantes a socorrista (4.288 hombres y 1.817 mujeres) que se formaron entre los años 1993 y 2016. Los resultados demuestran que, desde la entrada en vigor de dicha normativa, se ha incrementado el porcentaje de aspirantes que obtiene el diploma de socorrista acuático, pero se ha disminuido su nivel de competencia en el agua. Se recomienda que las instituciones competentes establezcan objetivos y criterios de evaluación que promuevan la mejora del nivel de competencia en el agua de estos profesionales


In 2006, the normative that currently regulates the training of lifeguards in the Autonomous Community of Madrid (Spain) came into force. The objective of this study is to know the influence of the application of this regulation on the percentage of applicants who obtain the aquatic lifeguard diploma and on their level of competence in the water. For this purpose, the time marks, accredited by 6,105 applicants to lifeguards (4,288 men and 1,817 women) who received this training between 1993 and 2016, have been analysed. The results show that, since the regulation came into force, the percentage of applicants who obtain the lifeguard diploma has increased, but their level of competence in the water has decreased. Therefore, it is recommended that objectives and assessment criteria that are established by the institutions, encourage the improvement of the level of competence in the water of these professionals

ABSTRACT

En este estudio se ha seleccionado a 2.528 aspirantes a la certificación de socorrista acuático (1.798 hombres y 730 mujeres). Todos ellos han realizado las cuatro pruebas físicas de agua cronometradas que se exigen para trabajar de socorrista en piscinas, instalaciones acuáticas y medio natural en la Comunidad Autónoma de Madrid (España). Del total de los participantes, 1.887 aspirantes realizaron dichas pruebas en vaso de 25 metros y 641 lo hicieron en vaso de 50 metros. El objetivo de este estudio es conocer la influencia de la longitud del vaso en el que se desarrollan estas pruebas físicas, sobre el porcentaje de aprobados y sobre las marcas de tiempo que emplean los participantes para realizarlas. Los resultados de esta investigación demuestran que la longitud del vaso en el que se evalúa a los aspirantes a socorrista, influye significativamente sobre las marcas de tiempo que obtienen y también sobre el número de aprobados


In this study 2.528 aspirants for aquatic lifeguard certification (1.798 men and 730 women) were selected. All the participants of the study have performed the four physical tests of chronometric water required in order to work as a lifeguard for swimming pools, aquatic and open water in the Comunidad Autónoma de Madrid (Spain). Of the whole participants, 1.887 aspirants were tested in a 25-meter pool and 641 were done so in a 50-meter pool. The aim of this study is to know the influence of the length of the pool in which these physical tests are developed, on the pass rate and on the time needed by the sample to carry them out. The results of this research show that the length of the pool in which the aspirants are evaluated, influences on the time marks obtained by them and also on the number of approved ones

ABSTRACT

Un importante componente de la condición física es la flexibilidad, particularmente para las personas mayores que suelen sufrir un deterioro de la misma con los años. Con el objetivo de conocer como la flexibilidad evoluciona a lo largo del tiempo en un grupo de personas mayores físicamente activas, este estudio longitudinal ha evaluado 54 sujetos mayores de 65 años (17 hombres y 37 mujeres), que participaban con regularidad en clases de mantenimiento físico global realizadas dos veces a la semana en sesiones de 60 minutos. Para la medición de la flexibilidad fueron aplicados los tests chair sit and reach y back scratch, en cuatro momentos distintos en un periodo total de 12 meses. Los resultados muestran la evolución positiva de la flexibilidad de las zonas testadas en el grupo de mayores practicantes de actividad física al final de un año. Se concluye que para los participantes previamente activos del estudio la flexibilidad fue mantenida con el tiempo e inclusive mejorada en el periodo total propuesto al conservarse un estilo de vida activo a través de la práctica regular de actividad física de mantenimiento global de la condición física (AU)


Flexibility is an important component of physical fitness, particularly in elderly people whose flexibility tend to deteriorate with the passing of time. The purpose of this longitudinal study was to determine how flexibility of older adults’ change over time. The control group consisted of 54 physically active adults (17 men and 37 women) all of which were 65 years and older. These adults participated in a 60 minute global fitness course, led by a trained instructor, twice a week. During the 12 month study, the subjects’ flexibility was measured at four different times through chair sit and reach and back scratch tests. The results show that the subjects who took part in this yearlong study, experienced positive results in flexibility in the areas tested. The results concluded that the subjects in the study that were previously engaged in regularly physical activity maintained and in some cases, improved flexibility through regular global fitness activity (AU)

ABSTRACT

El objetivo de este estudio es comprobar si el estilo de natación en el que están especializados los nadadores, influye sobre la extensibilidad isquiosural de los deportistas que han participado en esta investigación. El test empleado para este trabajo es el test "sit and reach". Se ha medido la extensibilidad isquiosural de todos los nadadores (N=36) de ambos sexos, que entrenan en un centro de tecnificación acuático español. La edad de los participantes del estudio oscila entre los 13 y los 17 años. Esta población de nadadores ha sido dividida en cuatro grupos diferentes, dependiendo del estilo de natación en el que están especializados (crol, espalda, braza y mariposa). Para conocer la influencia del estilo natación sobre los resultados obtenidos en el test "sit and reach", se ha aplicado un test inicial y nueve meses más tarde un test final, lo que ha permitido conocer también la evolución de las mediciones. Como conclusión, la extensibilidad isquiosural y su evolución, no está condicionada por el estilo de natación en el que están especializados los nadadores que han participado en este estudio (AU)


The aim of this research is to verify the swimming style in which swimmers are specialized, have has influences hamstring extensibility athletes who have had participated in this research. The employed test for this work was the "sits and reach" test. It was measured hamstring extensibility of all swimmers (N = 36) of both sexes, who train in Spanish aquatic center modernization. The age of the study participants is between 13 and 17 years. This population of swimmers has been divided into four different groups, depending on the style of swimming in which they are specialized (crawl, backstroke, breaststroke and butterfly). To determine the influence of swimming style on the results obtained in the test "sit and reach", it having had applied an initial test before, and a final test nine months later, which have had permitted also know the measurements evolution. In conclusion, the hamstring muscle extensibility and its evolution have had being not conditioned by swimming style of the swimmers (AU)

ABSTRACT

Objetivo. Se tratan de analizar aspectos de salud en Educación Física en Centros de la Comunidad de Madrid (España). Material y métodos. El estudio se ha desarrollado en 25 centros, con un total de 686 alumnos. El muestreo ha sido no probabilístico por elección y los datos se han recogido mediante cuestionarios y hojas de observación. Resultados y Discusión. Casi el 50% del alumnado tiene alguna enfermedad crónica. El desarrollo corporal es normal, la adaptación cardiovascular no es mala pero mejorable. La actividad física resulta insuficiente, la valoración de la condición física es inadecuada. Las instalaciones deportivas escolares en los centros públicos son claramente deficientes desde el punto de vista de la salud. Por último, en ninguno de los centros, el profesorado había recogido estos datos antes de la elaboración de esta investigación, salvo adaptaciones curriculares concretas pedidas por el alumnado. Es necesario buscar nuevas metodologías que estén ajustadas a criterios de salud y coordinadas con los servicios de salud (AU)


Objective. The aim of this paper is to analyze the health status of physical education students within the Community of Madrid (Spain). Material and methods. The study was carried out at 25 secondary schools centers with the participation of 686 students in total. A non-probability sampling was selected and data were collected through questionnaires and observation sheets. Results and discussion. The results of this study reveal that almost 50 % of the students claim to have a chronic disease and vision problems are the most predominant. On the other hand, physical development is representative of the average population; cardiovascular adaptation of students is not critical nor alarming but should be better. In addition, school physical activity provides very little help as the assessment of the physical condition is inappropriate and sports facilities in public schools are clearly deficient from the point of view of health. Finally, teachers in all the centres had failed to collect these data before conducting this research, except some specific curricular adaptations requested by the students. Teachers need to seek new work methods that comply with health criteria and that are coordinated with health services (AU)
