Sports team, specifically soccer and handball, has traditionally composing the physical education school contents as a curriculum component. There are several criticisms to extend this approach beyond the sportive discourse. While we recognize this need for expansion, we believe that the methodological endeavors to teach these sports content are still very poor, requiring, therefore, studies that guide us in changing not only contents but also the way of teaching it, which implies new e teaching, pupils and teaching relationship perspective. In this sense, the objective of this study was to identify and analyze, from a sports team tactics teaching approaches of invasion, the demonstrations by students, the phases of handball and soccer games, as well as the elements/dynamic structural, functional and operational in the same school environment. Given this objective, qualitative research, specifically, collaborative action research, best meets investigation is this scenario, since classroom teacher and students also participated in the content construction and strategies undertaken during the intervention. The study enrolled 28 students in the fifth grade, aging 10 to 11 years, in a Bauru/SP public school, physical education teacher and the researcher. Were planned and taught together, 14 classes over a semester with the handball and futsal content, guided for teaching tactics approaches. The data collections were made through systematic lessons observation (through filming and recording diary), interviews with students and descriptive reports made by the classroom teacher and researcher. The results indicate that there was an improvement in the phases of soccer and handball game, even though only the latter has changed its category phase to decentralized anarchic phase. Several students showed in the situational interviews, a more elaborate game understanding than the one identified in the game demonstration. In the analysis of relationship levels..

Obesity is a growing problem all over the world, reaching all age groups and social categories. This is a concern ing fact, because the current life style, more and more sedentary, favors the develop of this disease. Children suffer with this ill more and more prematurely and many of its consequences will be carried during all their lives. With the intention of better understand the relationship between obesity and children's motor development, the present research investigated, through psychomotor evaluations of equilibrium and appendicular motor coordination, based on the Exame Neurológico Evolutivo (ENE), the existence of changes in the performance of this variables in obese children and children with normal weight, in their first year on fundamental education in a public state school. The static equilibrium presented itself lower than normal in obese, compared to the normal weight group. Statistically significant differences were not found in respect to dynamic equilibrium and appendicular motor coordination. With that, we can conclude that the static equilibrium suffered influence of obesity, because the centre of gravity might have been changed due to excessive weight

Currently individuals are affected by a routine busy and they don't have time for physical activity, highlighting the sedentary lifestyle, a risk factor for cardiovascular diseases. For this reason, it focuses too much on cardiovascular diseases and the importance of physical practice. With the largest divulgation and variety of physical activities, activities that were not as practiced became popular, as is the case of resistive exercise. Much is said of the influence of resistance exercise in physical strength, in muscle development and in the quest for a more defined body. However, studies have shown beneficial contributions of resistance exercise on the cardiovascular system. During the physical effort, some changes occur in the body in order to meet the increased demand for oxygen. Among them is the increase in heart rate (HR), which varies with the intensity of effort. Thus, this research sought to contribute with an analysis of the HR behavior before, during and after 3 sets of hypertrophy, as far for the flexor group of the elbow as to the extensor group. It was observed that, although the HR has increased in the course of the series, the variations of HR were not significant between the flexor group and extensor group of the elbow joint. Also were not significant the differences between the variations of the HR from the 1ª to the 2ª series between the flexor group and extensor group, as well as to the variations from the 2ª to the 3ª series

Human beings' motor capacity development is essential, because it facilitates movement, enabling the performance of motor activities and others. In pre-school, boys and girls acquire the motor capacity development considered basic that, through several factors such as neurological maturation, which is in charge of providing more complete movements, and body growth, which has the goal of a better body domain, makes them improve individually the performance of motor abilities, but it can minimize them if laterality does not develop spontaneously. There by, this study focused on assessing the neurological development between genders of students engaging in fundamental school. Forty-three children of both genders at age six took part in this study. The evaluation occurred through the LEFÉVRE protocol (1976), which aims at assessing the maturity and development of the Nervous System through tests of the Evolutionary Neurological Exam (ENE), which comprises a series of tests involving specific tasks, regarding age in the static balance items, dynamic balance, appendicular coordination, trunk-member coordination, motor persistency, sensibility and synkinesis. Neurological development comparisons were performed between boys and girls for each item of the battery of tests. The results of the motor persistency and sensitiveness and sensorial activity tests were below the average for six-year-old children, but there was not any difference in gender comparison for each item of the battery of tests, only a small tendency for one of the genders, but meaningless, having a variance in only two tests of the synkinesis exam (Foot-hand and paper ball with the dominant hand), in which boys had a bigger percentage of synkinesis presence than girls did. The results also showed that the majority of the children assessed, both boys and girls have a right manual and pedal preference and the ocular laterality is approximately the same for left and right-handers. It was..

In humans, psychic and motor skills are interdependent, and therefore, cannot fail to take into account the influence of a good psychomotor development in the prevention of learning difficulties. Another factor that interferes with the learning process is the social. Family problems, socioeconomic status of the child, among others, may be associated with learning difficulties and, consequently, the student's performance. Therefore, the aim of this study was to investigate through the elements of psychomotor, if a delay in neuropsychomotor development may be related to the presence of learning problems in children entering elementary school. Also, determine whether there were differences regarding the presence or absence of these difficulties in students from middle and low social class and have family problems or not. For this, we analyzed two classes of 49 students from 1 year of elementary education at a public school in the city of Bauru/SP, aged between 6 and 7 years. These students were tested for the ENE proposed by Lefèvre (1976) to assess the maturity of the nervous system. A pre-designed questionnaire was answered by the teachers of classes to know students' academic performance, learning difficulties presented by them, social status and the presence of family problems. All students participating in the survey had the term sheet signed by the parents, allowing participation in the study. To reach the results, we applied the Anova and Tukey test for comparison analysis of mean age in the performance of ENE. To investigate the existence of a relationship between performance in the ENE and learning difficulties, we used the calculation of Pearson correlation. To analyze the difference in average scores of learning disabilities in students from different social classes and among those who had family problems or not, comparative graphs were used with the averages obtained from the questionnaire answered by the teachers for each learning...

Currently, we can observe a significant increase in the disappointment of the world population about education, which raised doubts about the current school system and resulted in a forced increase of interest in an education reconstruction. The investigation process of this research based itself in the qualitative exploratory approach, since it allows the interpretation of the reality of the investigated environment, and it is concern about the process and not the quantification of data. Five professionals who work for the prefecture in the city of Bauru participated in this study and they graduated in the third module of the continuing education of the department of physical education from UNESP/Bauru, which occur in the second semester of 2010. The purpose of the present study was to identify the reasons why teachers who work for the prefecture in the city of Bauru look for the continuing education in physical education and explore their expectations and perception about the course. Considering the analysis presented in this study, we can observe that the search for continuing education based itself in issues such as: the confusion that exists between theory and practice, where the teachers exemplifies that, after their initial education, theory was not consistent with the real needs of their pedagogical practice; the entry of students younger and younger in the infant and fundamental education; the search for contents that answer the needs of psychomotor development of children between 2 and 5 years old and, at the same time, contents for the inclusion of children with special needs; as well as political pedagogical issues. Even though the reasons presented in this research for the teachers to justify the search for the continuing education in physical education were of distinct natures, at the end we observed that the teachers had their expectations fulfilled, demonstrating that the course of continuing education can be a space of dialog...

Obesity is defined as excess body fat. It is considered today a serious public health problem and has reached high proportions in childhood and adolescence. Among factors highlight the lifestyle, poor diet and little physical activity for their development. Childhood obesity is not treated can become permanent in adulthood increases the risk of several diseases such as cardiovascular, metabolic and other disorders such as depression, low self-esteem among others. It's extreme need multidisciplinary intervention to prevent it, with guidelines on healthy eating habits and regular physical activity. Treatment is necessary in a multidisciplinary team of doctors, nutritionists, physical educators, psychologists and family that has a decisive weight in the treatment of obese children. The media could give more space for the disclosure of childhood obesity, so that the population is aware of this epidemic in a more serious understand its risks and health effects. This bibliographic study has character and aims to seek the causes of obesity, its consequences in adulthood and possible forms of intervention

The present study aimed to analyze the performance of 'boost' among water polo athletes. Twelve athletes (13,9 1,08 years, 169,0 6,0 cm and 59,5 13,5 kg of bodyweight) were under went to anthropometric assessment, body composition and maximum concentric strength of lower limbs. The jump test in the water was done by 'boost' and scaled to jump height. According to the results of strength (Leg Press 45: 157,08 43,30 kg Leg Extension: 72,08 12,86 kg), anthropometry (arm circumf.: 26,04 3,25 cm, thigh circumf.: 50,47 7,65 cm, sholder circumf.: 95,97 8,00 cm, elbow diam.: 4,74 0,51 cm, wrist diam.: 3,21 0,34 cm, knee diam.: 7,89 0,58 cm, biacromial diam.: 37,49 3,81 cm and bi-iliac diam.: 25,43 4,34 cm) and body composition (BMI: 20,74 4,00 kg / m² and% fat: 8,45 4,28), only stature showed a linear correlation (r= 0,595) to the values of vertical jump (height: 47,80 4,35 cm) performance. This anthropometric variable was one able to influence the height of performance by modifying it self, perhaps by maturity. However maturity may be an implicity feature of performance, since force is a concerned effect of the growth. Otherwise technique could play a mains role to the performance of the 'boost'. It can be conclude that possibly is advantageous for water polo athlete be higher and more mature for the realization of 'boost', and the training directed for the technique, but is necessary muscle fitness for the holder

The objective of this research study was quantify the power, force of vertical impulse, jumping height and the relation of the power output during the execution of the layup in basketball, by variables associated to anthropometric data. The study was carried with seven basketball players, university students, male, from the Universidade Estadual Paulista Julio Mesquita Filho (Unesp) basketball team, from Bauru City. The players were an age of 20,7 ± 2,4 years old, body weight of 77,1 ± 9,4 kg, body fat of 14,7 ± 3,6%, lean mass of 65,5 ± 6,2 kg and height of 180,0 ± 5,0 cm. Each player did the ability of the layup three times, with a previous time to adapt. The kinetic and kinematic values was obtained from the data of a system that consists of photocells and a contact carpet from a system called JumpSystemâ (CEFISE), using after that equations of UVRM and impulse. The photocells was dispose to capture the previous run-up, as well the speedy in the time of two steps of the layup, and it was also synchronized with the contact carpet in the last step, to preserve the exactly time of the propulsion of jump. In this way, the values and the kinetic variables found was vV (2,94 ± 0,3 m's-1), vH (11,3 ± 3,4 m's-1), vI (11,8 ± 3,2 m's-1), time of contact (0,214 ± 0,2 s), angle of jump (15,9 ± 6,26 graus) and H (44,3 ± 8,9 cm). The variables and the kinematic values found was FimpV (974,9 ± 119,03 N, PP (3112,9 ± 633,9 W) and PM (1556,4 ± 316,9 W). To better understand the ability of layup in basketball, as the kinetic variables, kinematic variables and anthropometrics that determine the performance, the study did correlations between dV (H) with vV, vH, vI, angle, FimpV, PP e PM; FimpV, PP e PM com with the kinetic variables of vV, vH, vI, angle, and anthropometric variables of PC and height, and correlations of PP e PM with %G and MM. So, significant results was found between the correlations of dV with FimpV (R2 = 0,81)...

To the practitioners of resistance exercise, a better performance is associated with nutritional habits and the help of nutritional supplements. Whatever, this use has been made improperly and without foundation, advised by persons not trained, leading to misuse. To analyze the profile of practitioners in the knowledge of and access to supplements, as well as knowledge about the sport and the need to use additional food resources. A questionnaire will be used to youths aged 15 to 21 consumers of nutritional supplements on the sports, the substance used, why the substance used, who appointed her, which substances have been used, satisfaction with that product, and socioeconomic characteristics of the individual. The data will be correlated by Pearson's correlation coefficient. It is expected that the abuse of supplements is associated with ease by socioeconomic status and experience in the sport for the little progress with the adoption of a routine training exercise in the circumstances only. The major difference compared to the goal of practice, was the motivation for the improvement of physical fitness (Guaruja 21% and Bauru 9.6%), with the intention of increasing muscle mass response occurring closer (Guaruja 22% and Bauru 19.2%) among respondents, and reported more emphasis on the Interior Health (17.3%). The use of supplements is somewhat similar to trends involving body aesthetics and fitness for participation in sports, in the Coast (hypertrophy: 33% body fat reduction, improved endurance and improved performance in sports: 20%), and beauty, fitness and health, the Interior (hypertrophy: 41% increase in strength: 22%, and quality of life: 15%). Interest in the use of supplements is mostly aimed at the improvement of overload training (Guaruja 67% and Bauru 56%) but the sources of information on the use of supplements have become more secure among the respondents of the Interior (gym teacher: 20%, Conferences and Symposia: 12%, and the...

Swimming is a sport well suited to any age group, it worked properly when the individual stimuli that provides assist in human development. But water stimulation, is not something that is so easily in physical education in Brazil. Development corresponds to changes that occur throughout life, but that depends on the stimuli provided. Several studies have shown positive effects of swimming in relation to the child. This study aimed to verify if children swimmers and physical education classes have better motor development than those who do not practice the sport. Collection was done with two groups of 10 students between 9 and 11 years. As a group consisting of non-swimmers, and another formed by those that complement the physical education class with the regular practice of swimming. To develop the study was administered a battery of the proposed motor adapted Rosa Neto (2002) in which each child performed tasks corresponding to their chronological age (CA) and were only able to perform the task at a later age, when it was obtained successful in completing the task as originally proposed. At the end of the application of all statistical tests was done getting mean and standard deviation of the old motor (IM), calculated the ratio General Motor (MGQ) for the classification of the child's motor development and application of the t test with p <0.05 to observe the level of significance in the results. The results showed that the group swimmers had better agility tests which resulted in a difference between (IC) and (IM) higher compared with the non-practitioner. They also had higher average (MGQ), but these were not sufficient to classify the group into another level of development, however, by observing isolated cases, two children that practice would be a greater level of development. Through the t test was observed that the group swimmers had significant difference in balance ability. We conclude that the swimming group got positive overall...

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

Postural control is needed to perform various daily activities, from staying in one posture, standing, to sports situations. Many studies have shown that sensory systems help to maintain posture stable; acquisition of perceptual information, particularly through head and eye movements, allows static and dynamic equilibrium. Research related to both motor behavior and physical activities such as gymnastics have contributed to a better understanding of complexities involved in human postural control. The purpose of this study was to review the related literature, searching for possible answers on how everyday and sports actions are performed, with respect to the control and maintenance of posture. Its focus was on how the human body acquires information from the sensory systems, vision in special, and how this information acts to support the control of posture and gaze

The purpose of the present study was to analyze the visual control of braking a bicycle when the cyclist is surprised by an obstacle in his way. According to Lee (1976), visually controlled braking based on time to collision information utilizes the optic variables tau and its first derivative in time, tau-dot, to initiating the braking action and regulating its intensity. Seven young adults performed a bicycle braking task in curvilinear trajectory under distinct velocity (high, medium, and low) and uncertainty (certainty and uncertainty) conditions. Results showed that, independently of velocity and uncertainty levels, participants utilized tau and tau-dot to initiating and regulating the braking action, avoiding collision with the obstacle. Cognitive, attentional, and other psychological factors resulting from both increased velocity and uncertainty were not capable of altering the use of time to collision information, corroborating the tested hypothesis
