Educação física e meio ambiente: uma proposta de sistematização dos conteúdos

As concepções sobre a importância do ensino da educação física escolar sofreram inúmeras mudanças desde a sua implementação como matéria no currículo da escola. Segundo SOARES (1994), a cultura corporal de movimento, é o conhecimento que constitui o conteúdo da educação física, esta é representada pela ginástica, esportes, lutas, capoeira, atividades físicas de aventura, práticas corporais alternativas, jogos, circo e dança. Os PCNs trazem uma proposta de problematizar os conteúdos de ensino, elencando alguns dos principais problemas que a sociedade deve se atentar para se manter equilibrada, estes são denominados Temas Transversais. Este estudo tem como propósito é investigar as relações entre o Meio Ambiente e a Educação Física na perspectiva da cultura corporal de movimento, mostrando que é possível o trabalho de ambas temáticas em conjunto. Em paralelo a isso, o estudo também tem como objetivo a elaboração de uma proposta de organização dos conteúdos que relacionam algumas temáticas do Meio Ambiente com os alguns conteúdos da Educação Física. Para o (PCN/BRASIL 1998), o papel da educação em relação ao meio ambiente é proporcionar para o aluno a possibilidade da construção de um mundo socialmente justo e ecologicamente equilibrado. O que requer responsabilidade coletiva e individual de qualquer individuo planetário, interferindo no modo como a sociedade programa as prioridades no seu cotidiano. Esta interferência só será possível se houver a construção dos conceitos gerando uma assimilação de valores. Para isso, propomos uma organização curricular dos conteúdos da educação física juntamente com as temáticas ambientais. Esta proposta teve como finalidade abranger o segundo ciclo do ensino fundamental. Para Gonzáles (2006) organizar e sistematizar os conteúdos de ensino da ...(Resumo completo, clicar acesso eletrônico abaixo)

Os paralelos entre a capoeira regional e os métodos ginásticos europeus do século XIX

Na Europa do século XIX, consolidava-se, entre outras linhas de pensamento, o científicismo positivista e a defesa médica da necessidade de saúde, retidão e disciplina dos cidadãos. Neste contexto, as atividades físicas naquele continente passaram a ser estudadas como pontes para se alcançar tais objetivos. São portanto criados os métodos ginásticos europeus a partir de atividades que se mostrassem efetivas para o desenvolvimento físico do indivíduo, como manifestações populares de proeza acrobáticas e exercícios militares. O fenômeno esportivo desse período conjugou-se com a influência dos sistemas ginásticos europeus e a visão positivista de corpo. Tal modelo consolidou-se como dominante no século XX e a Capoeira não foi exceção. Na virada do século XIX para o XX, o Brasil era um país que buscava sua identidade como nação em diversos ambitos sociais, como arte, raça, vestimenta, idioma, história e cultura em geral. No campo das atívidades físicas buscava-se também uma manifestação que nos representasse. E apesar de ilegal, a capoeira surgiu como forte candidato ao posto de ginástica nacional. Assim como manifestações populares chamaram a atenção dos criadores dos métodos ginásticos europeus, a capoeira também despontou pelos benefícios visíveis que trazia para seus praticantes. Muitos fizeram sua defesa até que Manoel dos Reis Machado, o Mestre Bimba, metodizou a capoeira de então para criar a Capoeira Regional Baiana, um estilo que, de acordo com ele, seria mais eficaz tanto como luta, esporte e forma de aquisição de desempenho físico. Neste trabalho abordaremos a Capoeira no contexto da constituição dos campos da ginástica e do esporte ocidentais do fim do século XIX e começo do século XX apresentando as influências que levaram à criação da Capoeira Regional ...(Resumo completo, clicar em acesso eletrônico abaixo)

Pluralidade cultural e educação física: elaboração de material didático

In 1997, the National Curriculum Parameters (BRASIL, 1997a) proposed the incorporation of the Transversal Themes in all of the knowledge areas. Specifically in the School Physical Education, the teacher working with transversality must stabilish bridges between the body culture practice with these themes. Promote this relationship is not a simple task and there are many problems that stuck the advance of this propose. So, thinking about making didactical formulat teaching stragies and think about the development of their practice. Another challenge is considerate as a beginning in the pedagogic activity the student’s knowledge and experience, as listening during the process of knowledge construction. In this way, the aim of this research is investigate the 8th and 9th grade of the primary school students conception about Cultural Plurality. After this, using the information taken gron the students, we are going to present subisidies to make a textbook, for the teachers and for students, with Physical Education activities possibilies with this Transversal Theme. Keeping in mind the aim of this research, we used the semi-structed interview as a instrument of data collection. The interview was made with 30 students of the 8th and 9th grade the primary school from two statual schools of Rio Claro city. The procediments were executed following the ethics comite requirements. In other to associate the Cultural Plurality with Physical Education, dance and physical adventure activities contents were selected. The results showed that the students know few thinks about this Transversal Themes, because they had apoor knowledge, according to National Curriculum Parameters. In scholar environment and Physical Education classes, there are many cases of prejudice and discrimination, mostly by the leack of ability. Nonetheless, most of the students are able to...(Complete abstract click electronic access below)

Aspectos motivacionais que levam os adolescentes à prática do futsal

Hoje em dia o futsal, seja nas aulas Educação Física escolar ou em Projetos comunitários, vem tentando fazer com que os adolescentes que atualmente se encontram numa vida sedentária devido a hipocinesia existente ligada aos avanços tecnológicos do século XXI, tais como Internet, videogame, locomoção automotora se situem num mundo onde possam entender que a prática esportiva além de ser motivante é extremamente fundamental para uma vida saudável. O conhecimento dos motivos que levam adolescentes a praticarem uma atividade motora, é um aspecto bastante relevante no desenvolvimento humano, e de fundamental importância para os Professores de Educação Física e Técnicos por proporcionar subsídios a esses profissionais envolvidos na prática de atividades físicas, para que estimule a preparação de seus programas e aulas voltadas mais para o interesse do praticante, facilitando a escolha das atividades, o ritmo da aula, o comportamento relacional e a maneira de motivar para uma prática alegre e prazerosa, além de evitar o abandono da modalidade esportiva e o sedentarismo por parte de alguns alunos. E o objetivo deste estudo foi exatamente verificar quais os motivos que levam os adolescentes, moradores da cidade de Rio Claro, do sexo masculino e feminino, a aderir à prática do futsal em seus horários livres. E como instrumento de analise foi utilizado o questionário TEOSQ aplicado por Machado, em estudos anteriores, com resultado interessante para análise. Com os resultados obtidos no presente estudo, podemos concluir que os fatores que mais motivam os atletas desta amostra a continuarem treinando futsal dependem muito das aulas e treinos passados pelo professor/técnico que deve passar treinos diversificados e sempre com novas atividades.

Influência da composição corporal e da síndrome metabólica sobre a relação da aptidão cardiorrespiratória com o estresse inflamatório

Physical activity is associated with lower cardiovascular disease risk factors, being cardiorespiratory fitness a major component of physical activity health related. Body fatness and sarcopenia are related to sedentary lifestyle leading to proinflammatory stress and lower cadiorespiratory capacity. This study aimed correlates C-reactive protein with cardiorespiratory fitness, analyzing the influences of anthropometrics variables and metabolic syndrome (MS) presence. the cross-sectional retrospective study included baseline data of 194 adults (62 male and 132 female), 53,74 ± 8,77 years, clinically and ethically selected for a lifestyle modification program. Total cholesterol (TC) and cholesterol lipoprotein fractions, triglycerides (TG) and glucose was dosed by dry chemistry (Vitros® system, Johnson & Johnson). Blood leukocytes was quantified by automatic cell counter (Coulter ABX®, Horiba). LDL-cholesterol was obtained by Friedwald formula. Serum ultrasensitive C-reactive protein (US-CRP) was accessed by the immunochemoluminescence method (Immulite 2000®, DPC Medlab). Weight, height, body mass index (BMI) and waist circumference (WC) were measured. Muscular mass and fat mass were obtained by bioelectrical impedance analysis (impedancemeter Quantum BIA-101Q®, Clinton Township). Arterial blood pressure was checked by auscultatory method and cardiorespiratory fitness was determined by ergoespirometric test (Balke protocol). The metabolic syndrome was diagnosed according NCEP – ATP III (2001), following recommendations of American Diabetes Association (2004). Pearson’s correlation crude and adjusted for confounders variables with p<0,05. The prevalence of MS was 30.4%. Crude correlation shows hsCRP was correlated inverse and significantly with VO2max (r= -0.21; p=-0.003) ...(Complete abstract click electronic access below)

Influência do alongamento prévio no pico de torque e na taxa de força em exercício de contração isométrica

The objective of this study was to investigate the influence of previous active static stretch on the isometric peak torque (PT) and rate of force development (RFD) measured from different time intervals from the beginning of muscle contraction. Participated of this study 15 male individuals, apparently healthy, with ages between 18 and 25 years, without regular physical activity practice. The individuals were submitted in different days to the following tests: 1) Familiarization session to the isokinetic dynamometer; 2) Two maximal isometric concentric contractions for knee extensors in isokinetic dynamometer to determine PT and RFD (Control), and; 3) Two active static stretching exercises for the dominant leg extensors (10 x 30 s for each exercise, with 20 s of rest). After the stretching, the isokinetic test was repeated (Post-Stretching). The conditions 2 and 3 were performed in random order. The RFD was considered as the mean slope of the moment-time curve at time intervals of 0-30, 0-50 and 0-100ms relative to the beginning of muscle contraction. It was verified significant reduction for both maximal RFD and PT after the stretching (p < 0.05). At intervals of 0- 30ms, 0-50ms and 0-100ms, the RFD at the conditions with stretching was similar to the RFD without stretching (p > 0.05). At intervals of 0-150ms and 0-200ms, the RFD obtained at the contraction without stretching was significantly higher that that obtained at the contraction with stretching (p < 0.05). It can be concluded that the static stretching, performed with duration of 600 s diminish isometric PT, maximal RFD and RFD measured at late phase (> 100 ms) of muscle contraction.

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Efeito do exercício prévio na determinação da potência crítica

The objective of this study was to analyze the influence of previous exercise on the determination of critical power (CP). Seven apparently healthy nontrained males, of 18 to 25 years, participated of this study. The subjects were submitted, in different days to the following protocols in a cyclergometer: 1) one progressive test until voluntary exhaustion for the determination of lactate threshold (LL), maximal oxygen uptake (VO2max) and its corresponding intensity (IVO2max); 2) six constant workload tests at 95,100 and 110% IVO2max until exhaustion with and without a previous exercise at 70% , in random order. The exhaustion times (tlim) at 95, 100 and 110% IVO2max were adjusted forme thress models of two parameters to estimate CP and anaerobic work capacity (AWC) [P=CTAn/tlim)+CP; tlim = CTAn/(P-PC); P=PC.tlim+ CTAn]. The model with the lowest standard error was considered for the estimation of CP. The tlim at 95% IVO2max was similar without (501 ± 140 s) and with previous exercise (473 ± 99 s). However, the tlim at 100% (381 ± 103 s and 334 ± 101 s) and 110% IVO2max (267 ± 163 s and 227 ± 68 s) was significantly longer with previous exercise. There was no significant difference in CP and AWCat conditions without (200 ± 27 W and 23 ± 11 kJ, respectively) and with previous exercise (212 ± 30 W and 18 ± 8 kJ, respectively). It can be concluded that the parameters of the relationship between power and time were not modified by the previous severe exercise

Efeito do pacing e do exercício prévio na performance aeróbia

The aim of this study was to analyze the influence of prior exercise on different intensity distribution strategies (pacing). The study included five male individuals, apparently healthy, aged between 18 and 25 years, and without regular practice of physical activities. The subjects were tested on different days following the protocols on a cycle ergometer: 1) a progressive ramp test, 2) three constant load tests in the intensities of 85%, 90% and 95% IVO2max to exhaustion, and 3) six tests with and without holding a prior exercise intensity of 70%  with different strategies for Even-intensity pace, ES (401 ± 70 W), which consists of an exercise at a pace and / or constant intensity from beginning to end; where intensity is initially increased to 10% less than the ES progressively increase to reach 10% above the intensity of ES, and; Fast-start; FS, where there is a reversal in the way of distributing intensity, ie the initial intensity is 10% higher than the value of ES decreased progressively to 10% below that ES. All these tests were performed in random order. The tlim with previous exercise was significantly shorter than without previous exercise at FS condition (p < 0.05). The VO2final obtained at ES condition was similar with (3243 ± 599 ml.min-1) and without (3252 ± 384 ml.min-1) previous aerobic exercise (p > 0.05). However, the VO2final obtained at FS condition was higher with (3291 ± 218 ml.min-1) than without (3097 ± 207 ml.min-1) previous aerobic exercise (p < 0.05). The heart rate was higher at ES condition with than without previous aerobic exercise (p < 0.05). There was no significant difference in this variable for FS condition with and without previous aerobic exercise (p > 0.05). It can be concluded that the results the previous exercise (70%) achieved lasting 6 minutes followed by 6 minutes of recovery appears to influence / commit ting the conditions during the pacing for this population

Treinamento de força unilateral: efeitos sobre a taxa de desenvolvimento de força do membro contralateral

The aim of this study was to analyze the effects of unilateral isokinetic strength training at high speed (180°.s-1) of the dominant leg on the rate of force development (RFD) of the contralateral limb. The study included 18 male individuals, apparently healthy, with an average of 23 years, and without regular practice of physical activities. The subjects were divided randomly into two groups: control group (GC) and isokinetic group (GISOC). Assessments were made of the values of peak isometric torque (PT isom) and RFD of both lower limbs in the pre-training. So, the GISOC underwent an isokinetic strength training with high speed (180°.s-1) for 6 weeks, with the dominant leg only and then reassessed. It was found that there was no significant improvement in value of PT isom (p> 0.05), and the RFD for the dominant limb had a significant improvement (p< 0.05) compared to the pre-training and that there was no transfer of values to the contralateral side (p> 0.05). It can be concluded that the isokinetic training at high speed was not enough for significant cross education

Variação aguda da frequência cardíaca durante série de hipertrofia para grupo flexor e extensor do cotovelo

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
