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

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
