En este artículo se ofrece una serie de consejos psicológico-deportivos para el futbolista. En resumen se presentan y discuten algunos factores psicológicos determinantes del rendimiento del futbolista. El texto se ofrece en forma de tesis seguida de consejos prácticos. Finalmente se brinda algunas consideraciones relacionadas con el trabajo psicológico semanal del futbolista. El propósito fundamental de esta guía es ayudar al futbolista, facilitándole algunos consejos que le permitan expresar su verdadero talento en la cancha. La guía es mucho más provechosa si se trabaja con el acompañamiento de un psicólogo deportivo.

Some physical characteristics are related to maximum sport performance, which has resulted in what has been denominated the morphological prototype. Knowing about this concept is of great relevance for physical activity professionals. Consequently, the purpose of this research was to give evidence as to whether the somatotypes of elite Cuban paddlers are related to international studies done in Spain (Esparza, 1993), Canada (Carter, 1999), Australia (Ackland et al, 2000), Argentina (Lentini et al, 2002), and the United States (Vaccaro et al, 2000). A total of 30 athletes were evaluated including 9 female kayakers and 21 male canoeists and kayakers. This study shows the significant heterogeneity found in this population based on the behavior of the somatotypes when contrasting the groups. Compared to the other reference studies, the endomorphic component proved to be the differentiating factor in this research. The foregoing allowed us to conclude that actions should be taken to modify this component in a way that Cuban athletes are closer to the anthropometric profile exhibited by international elite teams.

Sports and recreation management is addressed here using a model that combines the policies and methodologies applied in the Costa Rican context as a result of a concern to identify the real needs in the sports, recreation, and health promotion fields through the different manifestations of human movement. This approach has been developed during eight years of work in the Costa Rican Sports and Recreation Institute (Instituto Costarricense del Deporte y la Recreación-ICODER) together with different Costa Rican communities, both rural and urban, and local organizations, such as Comprehensive Development Community Associations, Sports and Recreation Community Boards (CCDR), Municipal Mayorships, and NGOs, among others. This article particularly takes into consideration the experience of the CCDRs as entities that have been given the responsibility by the Costa Rican Government to promote and manage municipal sports and recreation services with a convenient offering that would meet the needs of users or customers. In this way, this article is aimed at answering the question on how Boards should conduct an efficient management in a way that they also meet the needs of public users or customers in the municipalities of the country, by proposing a management model that serves as an additional instrument to improving the already existing services managed by the aforementioned entities. This study presents a model of Costa Rican management structured with the theoretical elements that currently define the organization and planning of sports and recreation as a service.

The aims of the present study were to determine the effect of firefighter's boots on the vertical component of the ground reaction force (GRF) at heel strike, also known as heel strike transient and to analyze the effect of the viscoelastic insoles placed into the firefighter’s boots on this force during the gait. The magnitude of the impact force (FZI) from the vertical ground reaction force, the time to the production of this force (TZI) and the loading rate (GC) were registered. 39 firefighters without any pathology during 2 years before the study were recruited. Three different walking conditions were tested: 1) gait with firefighter's boots, 2) gait with firefighter's boots and viscoelastic insoles and 3) gait with sport shoes. The results showed a higher production and magnitude of the impact force during gait with firefighter's boots than during gait with sport shoes (13,1 vs. 2,6 % of occurrence of the impact force and 61,39 ± 35,18 %BW (body weight) vs. 49,38 ± 22,99 %BW, respectively). The gait with viscoelastic insoles placed into the firefighter's boots did not show significant differences in any of the parameters characterizing the impact force compared to the gait without insoles. The results of this study show a lower cushioning of the impact force during the gait with firefighter's boots in comparison to the gait with sport shoes and the inefficiency of the viscoelastic insoles placed inside the firefighter's boots to ameliorate the cushioning of the impact force at natural walking speed.
