title: The leader perceptions about the effectiveness of his organization: a case study with the Portuguese Federation of Canoeing

description: This study aims to understand how to configure organizational effectiveness from the perspective of the President of the Portuguese Federation of Canoeing and identify factors that are privileged by him to evaluate the effectiveness of his federation, based in the Competing Values Approach. Based on case study, characterized by qualitative research, this study was based on content analysis of a semi-structured interview and documental analysis of the Plan of Activity 2010. It was found that the President favors factors listed in the quadrants corresponding to Open System Model, like innovation and resource acquisition, and Rational Goal Model, like productivity and goal setting, for assessing the effectiveness of the Federation, although considering its effectiveness as a one-dimensional concept, based on the achievement of sports results, with exclusive focus on Rational Goal Model.

title: Physical education in middle school: development of concepts and health-related physical fitness

description: The aim of this study was to investigate the development of concepts, levels of physical fitness related to health and physical activity patterns provided by the Physical Education (PE) classes. The sample consisted of 40 students (24 boys, 16 girls) high school students. Physical fitness was measured by the sit and reach test, running in 9 minutes and abdominal strength in 1 minute, belonging to the battery of tests PROESP. The knowledge was determined by theoretical test. The physical activity score was estimated by the International Physical Activity Questionnaire (IPAQ). In 30 PE classes the teaching contents were related to the concepts of stretching and gym exercises: Interval fitness and running. There were significant changes in abdominal strength, flexibility and knowledge to both sexes and aerobic endurance for girls, indicating that classes, worked through teaching procedures aimed at health promotion can modify the concepts and health-related physical fitness of high school students.

title: The influence of number of players on small-sided handball games: changing on technical and tactical dynamic

description: The aim of this study was to verity the effects of different formats of handball game (2 vs 2, 3 vs 3 and 4 vs 4) on technical and tactical performance of Physical Education students. Eight male students (18.25 ± 1.04 years old) participated in this study. It was possible to verify significant statistical differences in the number of ball contacts, number of shoulder passes and shoulder passes completed. It was also possible to verify significant statistical differences in the organized attack and counterattack. Therefore, it was possible to conclude that smaller formats of small-sided handball games allows to increase the technical and tactical actions, thus being more appropriated to early stages of learning.

title: Influence of knee positions on torque and myoelectric activity of triceps surae at maximum isometric plantar flexion

description: The aim of this study was to compare the maximum torque of plantar flexors using two knee positions and analyze the mioelectric activity variation of the muscles in both conditions. The sample was composed of 14 healthy men. The participants were positioned on the dynamometer with the right foot attached to the adapter in neutral position (ankle at 90º). Two five seconds of two consecutives maximum isometric voluntary contractions were obtained for each knee position: full extended and 90o. The gastrocnemius lateralis (GNL), medialis (GNM) and soleus RMS value of eletomyography signal and the plantar flexor peak torque average were acquired during three intermediate seconds. The average torques in the knee positions of extension and flexion were 100.4 ± 17.4 Nm and 72.6 ± 18.4 Nm respectively. With the knee flexed, the gastrocnemius presented a decreased activation (40.5 ± 10.5 e 31.7 ± 25.6% for lateral and medial, respectively) while the soleus showed an increased (35.6 ± 28.9%). The reduction of torque appears to result from a compromise between the inhibition of myoelectric activity of the gastrocnemius medialis and lateralis, while the soleus activation is optimized. The results may contribute to exercise prescription plantar flexors muscles emphasizing the different muscles activation varying the knee position.

title: Genetics and sport performance: current challenges and directions to the future

description: In recent years there has been a great progress in molecular biology techniques, which has facilitated the researches on influence of genetics on human performance. There are specific regions of DNA that can vary between individuals. Such variations (i.e., polymorphisms) may, in part, explain why some individuals have differentiated responses to certain stimuli, including the responses to sports training. In a particular sport, the presence of specific polymorphisms may contribute to high levels of performance. Since 1998, several polymorphisms have been associated with athletic phenotypes; however the accumulation of information generated over these 15 years shows that the influence of genetics to sport is extremely complex. In this review, we will summarise the current status of the field, discussing the implications of available knowledge for the practice of professionals involved with the sport and suggesting future directions for research. We also discuss topics related to the importance of polygenic profile characterization of athletes, methods for the identification of new polymorphisms associated with physical performance, the use of genetic testing for predicting competitive success, and how crucial is the genetic profile for the success athletes in competition.

title: Wich technical-tactical actions performed in futsal matches can discriminate the result of winning or defeat?

description: The objectives of this study were to verify whether specific technical-tactical actions of futsal would be able to discriminate the result in high-performance futsal matches. Forty matches from one futsal team were analyzed over two National League seasons, in which the assessed team showed the result of winning or defeat. For each match, the number of total technical-tactical actions were analyzed: Tackles done, Tackles suffered, Total shots done, Total shots suffered, Shots on target done, Shots on target suffered, Incomplete pass done, Opponent incomplete pass; as well coefficient indexes for each technical-tactical action, from the ratio between action done and suffered. Discriminant Analysis was realized using simultaneous estimation method. Only Tackles done, Tackles suffered and Tackles coefficient showed discriminating loads above 0.40, which indicate that these variables can discriminate the result of winning and defeat in futsal matches. It can be concluded that efficiency related to Tackles done and Tackles suffered is a determinant point to achieve the winning in high-performance futsal match. This study shows that the defensive system in a futsal team, in which must be considered both tactical organization and appropriate technique to perform the tackle could discriminate the match’s result in the analyzed team. Offensive system is also important in order to provide a better attack organization, and consequently, a lower possibility to suffer a tackle.

title: Drive for muscularity aspects among Physical Education undergraduate students

description: Drive for Muscularity refers to the desire to achieve an ideal muscular body, as well the degree of concern that an individual can have about increasing muscle mass and the motivation to do so. The aim of this study was to contribute for the comprehension of drive for muscularity in the Brazilian cultural scenario, looking for beliefs, feelings and behaviours associated with this construct, in male physical education students. To generate the evidences, two focus groups, with five participants in each one, were conducted. Through the thematic decomposition were identified two main topics and five subtopics distributed between them: “it is important to be muscular”; “it is important to be enough muscular”; “the build of the muscular body”; “the price of being far from the muscular ideal” and “the price to achieve the muscular ideal”. We concluded that body appearance and function are important, those who appear to be strong must be capable of lift weights. The muscular enough body, with low body fat, is the one that is valued, either in the labor market. The most legitimate way to achieve the muscular body is through an ascetic routine of physical training, balanced diet and rest. Food supplements are acceptable additional resources. The use of anabolic steroids by those with unfavorable “genetic inheritance” is initially “forgiven”, but the body that results from this resource is a source of ambiguous feelings.

title: The effect of number of players on physical demand and physiological responses during small-sided games in under-15 soccer players

description: The aim of this study was to analyze the effect of number of players in small-sided games (SSG) on time-motion characteristics and physiological responses in young soccer players. Fourteen soccer players from a state-level youth soccer team (age 14.4 ± 0.5 years; body mass 56.2 ± 7.0 kg; height 1.7 ± 0.1 m; BMI 20.3 ± 1.4 kg∙m-2) performed two formats (3 vs. 3 e 7 vs. 7) of the SSG. Heart rate (HR), rating perceived exertion (RPE) and blood lactate ([La]) and physical demands were analyzed using a global positioning system (GPS). Although there were not statistical differences in distance covered at different zones between SSG formats, the total distance covered, distance covered at high-speed, the quantity of high-intensity activities and quantity of accelerations &gt; 1.0 m∙s-2 were higher (p &lt; 0.05) during SSG 3 vs. 3 (1794 m; 885 m; 69; 87, respectively) than SSG 7 vs. 7 (1663 m; 712 m; 57; 68). The percentage of maximal heart rate (HRmax), RPE and [La] were higher (p &lt; 0.05) in the SSG 3 vs. 3 than in 7 vs. 7 (91.3%; 6.1 a.u.; 5.0 mmol∙L-1 vs. 85.1%; 5.1 a.u.; 2.1 mmol∙L-1, respectively). The results show that intensity is greater during SSG 3 vs. 3 than in 7 vs. 7; furthermore, the physical demand is influenced by the number of players per team, with higher total distance covered and distance at high-speed during SSG 3 vs. 3. The players also perform higher number of activities at high-intensity and accelerations during SSG 3 vs. 3.
