Judocas olímpicos Brasileiros: fatores de apoio psicossocial para o desenvolvimento do talento esportivo

Although judo is a traditional Olympic Sport in Brazil, little is known regarding the key aspects to develop talents at the national scenario. The objective of this study was to analyze the psychosocial supporting factors that are seen in the development of talented male Brazilian Judo athletes. A sample of 6 athletes that were in the Athens Olympic Games of 2004 was studied. Research was designed on qualitative basis and used a three open questions interview as investigative tool. Results were analyzed using the discourse of the collective subject. Discourses indicated as important, factors related to: a) family support; b) pleasure in practice; and c) athletes determination, reinforcing the international scientific literature regarding the importance of psychosocial factors to talent development in several knowledge domains.

INICIAÇÃO ESPORTIVA, TEMPO DE PRÁTICA E DESENVOLVIMENTO DE JUDOCAS OLÍMPICOS BRASILEIROS

The objective of this study was to analyze the age of sports initiation, the initiation process in judo and practice time of Brazilian judo Olympic players. For this, we used a sample of 6 judokas belonging to the Brazilian team at the Olympic Games of Athens 2004. The research used an interview tool that consists in 2 open questions. The speeches indicated that early training is one of the most relevant factors for the acquisition of a high level of performance subsequent to the time that the average age of initiation into the sport occurred at around 6.2 ± 1.3 years. Family support combined with a microsystem development of athletes, form an environment capable of generating international level judo athletes.

Trait anxiety and goal difficulty on learning to climb the Bachman ladder.

This study examined the effects of trait anxiety and goal setting on learning of the Bachman ladder. It was hypothesized that easy goals would increase learning for individuals with high trait anxiety while hard goals would increase learning for individuals with low trait anxiety. 80 high school students (40 boys, 40 girls; M age = 15 yr., SD = 1.0) filled out the Brazilian State–Trait Anxiety Inventory (STAI) for trait anxiety. The experiment was divided into four phases: acquisition, immediate transfer (after 5 min.), delayed transfer, and retention (after 24 hr.). On the transfer phases, the participants started climbing the ladder with the foot opposite of that used in acquisition. Participants were assigned to one of four experimental groups combining high and low anxiety traits and hard and easy goals. Variances were analyzed with repeated measurements on the last factor of all phases. The results showed the performance increased during the acquisition phase and no effects were observed in any phases.

Is the technical performance of young soccer players influenced by hormonal status, sexual maturity, anthropometric profile, and physical performance?

The aim of this study was to examine the influence of hormonal status, anthropometric profile, sexual maturity level, and physical performance on the technical abilities of 40 young male soccer players during small-sided games (SSGs). Anthropometric profiling, saliva sampling, sexual maturity assessment (Tanner scale), and physical performance tests (Yo-Yo and vertical jumps) were conducted two weeks prior to the SSGs. Salivary testosterone was determined by the enzyme-linked immunosorbent assay method. Technical performance was determined by the frequency of actions during SSGs. Principal component analyses identified four technical actions of importance: total number of passes, effectiveness, goal attempts, and total tackles. A multivariate canonical correlation analysis was then employed to verify the prediction of a multiple dependent variables set (composed of four technical actions) from an independent set of variables, composed of testosterone concentration, stage of pubic hair and genitalia development, vertical jumps and Yo-Yo performance. A moderate-to-large relationship between the technical performance set and the independent set was observed. The canonical correlation was 0.75 with a canonical R2 of 0.45. The highest structure coefficient in the technical performance set was observed for tackles (0.77), while testosterone presented the highest structure coefficient (0.75) for the variables of the independent set. The current data suggest that the selected independent set of variables might be useful in predicting SSG performance in young soccer players. Coaches should be aware that physical development plays a key role in technical performance to avoid decision-making mistakes during the selection of young players.

Iniciación deportiva y tiempo de practica de luchadores olímpicos de judo brasileños: la luz del entrenamiento a largo plazo y del proceso del desarollo de talentos
