Assessment of Risk Factors for Injuries on Beaches

The purpose of this study was to examine the risk factors for injuries on a beach. It is important to know all the risk fctors for injuries that can happen in a beach in order to prevent accidents. Risk factors were grouped in four main categories: beach morphology (BM), beach equipment (BE), lifeguard service (LS) and miscellaneous aspects (MA). All of them were evaluated according to their importance using a survey by Spanish and International experts. Descriptive analysis showed that LS is the main mechanism by which to reduce injuries on a beach. Lifeguard service in-service training is very important as are the affluence and activities developed by the beach patrons, the influences of weather and climate on the beach and other infrastructures as risk factors for dangers on beaches

THROWING VELOCITY IN ELITE WATER POLO FROM DIFFERENT AREAS OF THE SWIMMING POOL

The aim of this study is threefold: 1) To identify the throwing velocity during a match; 2) to identify possible differences in throwing velocities between male and female players; 3) to determine shot velocity from different zones of the court during real competition. We analyzed the water polo world championship. In order to evaluate the precise strength production, a radar gun was used. A one-way analysis of variance was applied (ANOVA) to study differences among playing areas. In addition, a t-Test for repeated measures was employed to compare different groups. This study identifies three major zones of goal shot. We identified the highest throwing velocity zones and the zones with highest shot number. In addition, the results show that the penalty shot is the fastest shot

Analysis of Self-Determined Motivation in Basketball Players through Goal Orientations

The purpose of this study was twofold. Firstly to examine the relations between the different constructs that defines Nicholls’ Achievement Goal Theory and Deci and Ryan’s self-determination theory. Secondly to analyse the differences that exist between them with respect to the socio-demographic variables gender and age. A sample of 292 federated basketball players from the Region of Murcia (Spain) with ages between 14 and 18 years old was used. In addition, Castilian versions of The Perception of Success Questionnaire (POSQ) and the Sports Motivational Scale (SMS) were administered. Three statistical analyses were employed, a descriptive analysis, a correlation analysis and a regression analysis. The results showed a positive relation between ego orientation, extrinsic motivation and amotivation. The motivational relations between both theories and the differences with respect to gender and age are discussed.We have found out that mainly gender and also age differences are strong predictors of ego orientation, extrinsic motivation of external regulation and amotivation. We can also confirm that extrinsic motivation of external regulation positively predicts ego orientation and a decrease of task orientation. The results ratify the use of the Spanish version of the SMS to measure different types of motivation within the sports context

Motives of practice in the field of non-competitive physical activity

Resumen basado en el de la publicaciónSe analizan cuáles son los motivos de práctica en el ámbito de la actividad física no competitiva. Para ello se administró la escala de medición de los motivos de actividad física revisada (MPAM-R, Motives for Physical Activity Measure-Revised) de Ryan, Frederick, Lepes, Rubio y Sheldon (1997) y validada en España por Moreno, Cervelló y Martínez (2007) a una muestra compuesta por 271 sujetos adultos practicantes de actividades físicas no competitivas. Se realizó un análisis factorial de componentes principales de la escala y un análisis de correlación de las distintas subescalas. Los resultados manifiestan que las principales razones para realizar actividades físicas son el fomento de las relaciones sociales así como la obtención de placer y diversión, por delante de otras como la competencia, el mantenimiento y mejora de la salud y la apariencia.AndalucíaES

Position Specific Anthropometry and Throwing Velocity of Elite female Water Polo Players.

This study was conducted with the following aims: (a) to describe the effect of playing position on anthropometrics and throwing velocity in elite female water polo players and (b) to observe any relationships between anthropometric parameters and throwing velocity. To achieve these aims, we analyzed a total of 46 female elite players (age: 22.5 ± 5.1 years; height: 172.0 ± 6.9 cm, body mass: 67.4 ± 7.5 kg) members of the top 4 teams of the Spanish Honour Division women league (21 offensive wings players, 17 center, and 8 goalkeepers). Wings were significantly shorter and had smaller arm spans than goalkeepers and center players. Goalkeepers demonstrated longer forearm lengths than wing and center players. No other significant differences were evident between positions in terms of anthropometric, strength, or throwing velocity variables The somatotype of the offensive wing players was mesomorphic, whereas centers were endomorph (classified as endomesomorphic). Height, arm span, muscular mass, biepicondylar breadth of the humerus, arm girth (relaxed and tensed), and forearm girth were related to throwing velocity. In conclusion, only a small number of anthropometric differences exist between players of different positions in elite female water polo. Shorter players with smaller arm spans may be better suited to the wings, whereas athletes with longer forearms may be better suited to the goalkeeper position. Taller, more muscular athletes with wider arm spans, broader humeri, and wider arms (relaxed and flexed) tended to throw with increased velocity. Trainers should focus on increasing the modifiable characteristics (muscle mass and arm girths) that contribute to throwing velocity in this population.Actividad Física y Deport

Self-Determined, Goal Orientations and Motivational Climate in Physical Education

The aim of this study was to analyze the degree of prediction to which the goal orientation adopted by the student and the motivational climate created by the teacher as perceived by students in physical education classes, have on the students’ self-determined behaviors. The sample included 846 high school students from the Murcia region (Spain) aged 12–19 years old. The Spanish versions of the Perception of Success Questionnaire, the Perceived Motivational Climate in Sport Questionnaire-2 and the Motivational Climate Scale were the instruments used to collect data. A descriptive, correlated and stepwise multiple regression analysis was carried out following the Self Determination Index. Results show that the majority of students were task oriented, they perceive a task climate and were intrinsically motivated. Moreover, the relevance of the role of the teacher in physical education classes was demonstrated, as the main predictor variable of selfdetermined behavior in students was the motivational climate

Importance of basic CPR techniques. A study in the Region of Murcia

Annually in Spain many people die from diseases related to heart. Heart attack is the main cause of such deaths. Know and control the basic techniques of basic Cardiopulmonary resuscitation (CPR) are essential to help a person away from these features. This study examined 1) the importance of knowing these techniques in the general population, and 2) the perception of the difficulty of understanding and application of techniques. We used a questionnaire designed "ad hoc" as a tool for collecting information. The instrument was subjected to validation and reliability for the study. The questionnaire was completed by 235 volunteers aged between 10 and 65. We performed a descriptive analysis, based on gender and the variables importance of knowledge and learning / apply techniques. Among the most relevant results, we emphasize an interest of society to improve training in this type of knowledge. Training would be ideal in most age groups of people (teens to seniors). Likewise, CPR techniques are easy to understand and execute a lesser extent, relevant perception among people who acknowledge and application these technique

Is Rescuer Cardiopulmonary Resuscitation Jeopardised by Previous Fatiguing Exercise?

Survival outcomes increase significantly when cardiopulmonary resuscitation (CPR) is provided correctly, but rescuer’s fatigue can compromise CPR delivery. We investigated the effect of a 100-m maximal run on CPR and physiological variables in 14 emergency medical technicians (age 29.2 ± 5.8 years, height 171.2 ± 1.1 cm and weight 73.4 ± 13.1 kg). Using an adult manikin and a compression-ventilation ratio of 30:2, participants performed 4-min CPR after 4-min baseline conditions (CPR) and 4-min CPR after a 100-m maximal run carrying emergency material (CPR-run). Physiological variables were continuously measured during baseline and CPR conditions using a portable gas analyzer (K4b2, Cosmed, Rome, Italy) and analyzed using two HD video cameras (Sony, HDR PJ30VE, Japan). Higher VO2 (14.4 ± 2.1 and 22.0 ± 2.5 mL·kg−1·min−1) and heart rate (123 ± 17 and 148 ± 17 bpm) were found for CPR-run. However, the compression rate was also higher during the CPR-run (373 ± 51 vs. 340 ± 49) and between every three complete cycles (81 ± 9 vs. 74 ± 14, 99 ± 14 vs. 90 ± 10, 99 ± 10 vs. 90 ± 10, and, 101 ± 15 vs. 94 ± 11, for cycle 3, 6, 9 and 12, respectively). Fatigue induced by the 100-m maximal run had a strong impact on physiological variables, but a mild impact on CPR emergency medical technicians’ performance
