Comparação antropométrica, composição corporal, somatotipo e saltos verticais de atletas de voleibol de praia masculino

The kinanthropometric characteristics are used by the sports science as selection criteria and detection of talents. Hence, this study aimed at comparing the anthropometrical profile, the body composition, the somatotype and the vertical jumps of the beach volleyball players. This study consists of 79 male beach volleyball players, being forty nine (n=49) Brazilian participants of the National Circuit and thirty (n=30) of 15 countries participating in the XV Pan American Games. In order to analyze the vertical jumps of the Brazilian the participants were allocated into two groups (G1 and G2) in agreement with the national ranking of their teams. The vertical jump protocol developed by Smith and collaborators was used to evaluate the vertical jumps of spike and block. The Heath-Carter anthropometrical technique (1990) was used for calculating the somatotype. The Student s t test with the Bonferroni adjustment was used to calculate the differences among the investigated variables. The multiple regression analysis was used to identify the contributions of the anthropometrical variables in the performance of the vertical jumps and the multivariance analysis was used to calculate the differences among the components of the somatotype. The Brazilian athletes of G1 were better than G2 in the spike jump (p <0.01), block jump (p <0.01) and in the block difference (p <0.01). The prediction model of the spike jump of G2 included the body mass and standing spike reach (adjusted R2 = 0.77), the body mass and the standing block reach were also included in the model of the block jump (adjusted R2 = 0.73). The regression model of G1 was not statistically significant. As for the somatotype, statistically significant differences were found between the Brazilians and the Pan Americans (Wilks' lambda = 0.498; p <0.05). The Brazilian somatotype was classified as balanced mesomorph (2.7-4.3-3.0) and the Pan American somatotype as endomorphic mesomorph (3.5-4.6-2.4). As to the specific position of the block game (2.8-4.3-2.9) and the defense game (2.6-4.4-3.0), the Brazilian somatotype was classified as balanced mesomorph and the Pan American somatotype, the block (3.7-4.4-2.4) and the defense (3.4-4.9-2.3), was classified as endomorphic mesomorph. In conclusion, the vertical jump height (spike and block) influences the male Brazilian beach volleyball players performance. The physical type of the Brazilian blockers and defenders was similar with relationship to the somatotype. The Brazilian and Pan American beach volleyball players differ in terms of kinanthropometric characteristics. This work had a multidisciplinary feature with the participation of several departments and laboratories, like the Physiotherapy Department, the Nutrition Department, the Physical Education Laboratory, thus corroborating the multidisciplinary research feature

Características físicas, somatotipo e desempenho de corredores de 100 e 400 metros no Rio Grande do Norte

Objective: The aim of the study was to investigate physical characteristics and to examine association between somatotype and performance in collegiate runners of 100 m and 400 m. Methods: The sample, male runners (n=39) competing at the regional level in the state of Rio Grande do Norte, Brazil, had height, body mass, skinfolds, limb circumference and skeletal breadths measured. Then, the somatotype was calculated by Health-Carter method. Races (100 m and 400 m) were held to assess athletic performance. Descriptive statistics were calculated for the total sample, as well as for the 100 m and 400 m groups, and established four subgroups, named quartiles. For analysis between groups of runners (100 m x 400 m) was used Student's t test for independent samples. To examine the relationship between the race times and anthropometric variables, was used the Pearson correlation test. The somatotype dispersion distance and somatotype spatial distance were calculated among subgroups. One-way analysis of variance, the Wilcoxon test followed of Tukey post test, and correlation analysis were used with a significance level of p<0.05. Results: Somatotype with mesomorphy and ectomorphy dominance was exhibited by 100 m and 400 m athletes. Endomorphy was low in both groups, especially in 400m runners, who had more elongated body types than 100 m runners. When separately compared by athletic performance quartile, 100 m sprinters of better qualifications (G100-G1) had somatotype with dominant mesomorphy, whereas 400 m runners had somatotype with dominant ectomorphy. A significant correlation (r = -0.55, p=0.008) between calf circumference and 100 m race times was observed showing the importance of muscularity, whereas a significant correlation was found between height and 400 m race times (r = -0.53, p=0.02) showing the importance of linearity. Conclusion: Runners of 100 and 400 may show differences in physical characteristics, depending on the level of athletic performance. Anthropometric periodic evaluations may help in the training process of these athletes. However, more specific assessment parameters should be taken into account, because somatotype by itself has not power to predict whether an individual will succeed in racing speed

Esporte como experiência estética e educativaEsporte educativa: uma abordagem fenomenológica

This paper deals with sport as a possibility of disclosing the sensible, and defends the idea that being a sportsperson equals living an aesthetic and educative experience in which one can interacts with the sensible by the athletic body s reverberation of sensations in the dimension of the experienced. We try to answer, in our work, basically three questions: what moves the athlete when practicing a sport? Which are the meanings and motivations for the practice of sports? At what measure the athlete s experience gains an educational character? Sport is debated in this work as an extension of the living, as long as it tries to understand the meanings inherent to sport itself as well as to the sportive experience as a kind of education. In support of our argument, we give a theoretic and philosophical approach to our thesis, based on thinkers like Maurice Merleau-Ponty, Walter Benjamin, Marcel Mauss and Friedrich Schiller. For this purpose, we get support on the phenomenology of the French philosopher Maurice Merleau-Ponty. Our reference is the living world of the athlete and his experience as a field of the sensible. Our point of departure is the analysis of the narratives of sport experiences, including five aesthetic elements; time and space of the body in the sports courts; the look on the sportive context; the contact with the adversary; victory and defeat; the technical gesture. Besides it, we worked out an aesthetic evaluation of the movies Olympia and Invictus , what let us discuss three thematic categories: sensibility, emotions and the play paradox. Subsequently, we point sport as an optimizer of the sensible education, present on the body s processes, like the body in movement. It was also made clear along this paper that we tried to accomplish an analysis on sports centered in the athlete s body as an outfit of the senses to things related to the sensible, whose aesthetic experience overpasses any deterministic conception that should sum up the sportive world to mercantilization, discipline practices and mechanicism. This approach franchises gateways to a Physical Education which, containing sports as one of its support, let pupils enjoy the pleasure of constructing common objectives, incorporating the capacity of replicating, re-making and playing as a field of possibilities offered by an education characterized as being moving, sensible and fitful to a body in movement
