As fases do treinamento de natação influenciam os substratos energéticos, cortisol e leucócitos

The effect of physical exercise in immune function has been extensively studied. The intensity and duration of physical exercise have considerable influence in immunologic parameters. However, few studies have compared different exercise intensities in different stages of a physical training program. Thus, the aim of this study was to verify the metabolic, hormonal and immunologic changes before and after acute intermittent swimming exercise, following different stages of training program. Seventeen male swimmers were evaluated in three stages of training. The intensity of the three sessions was 90% (anaerobic potency – PAN), 70% (aerobic potency - PAE) and 98% (lactate tolerance – TLA) of the maximal speed from the best time of the distance, resulted from peak performance in competition. Blood samples were collected pre and immediately after exercise for cells counting and measurement of substrates and cortisol concentrations. It was used ANOVA to verify the significance of difference (p<0.05). There was a significant increase of glucose and cortisol post exercise in the PAN and PAE sessions. Glutamine increased significantly in PAE and TLA. Leukocytes increased significantly after the three different sessions and lymphocytes decreased significantly on PAE and TLA. In conclusion, it was demonstrated that changes of the several parameters studied in different stages of training program can cause temporary alterations in immune cells and may compromise resistance to common minor illnesses and athlete performance.

Capacidade de força dos membros superiores em competidores de montaria em touros

This study did evaluate the handgrip strength capacity of bull riding practitioners and recreational practitioners in order to obtain parameters of the muscular fitness of subjects undertaken this sports practice. Twenty right-handed subjects were grouped into bull riding athletes (10 individuals at AMT: 174.5 ± 5.2 cm of height, 78.9 ± 12 kg of body weight, 24.7 ± 6.1 years, and 13,8 ± 2.4% for body fat) and non-athletes (10 subjects n-AMR: 178.5 ± 7.3 cm of height, 81.2 ± 8.8kg of body weight, 21.7 ± 2.3 years, and 13.8 ± 1.9% of body fat). They were underwent to protocols of handgrip strength evaluation by a standard and specific dynamometry (simulating a bull riding posture) of right (DPD e DED) e left (DEP e DEE) hands. The dynamic force values from one repetition to maximum test (1RM) were either obtained in conventional load-based system for upper limbs exercises. The values were compared by the test-t for independent data, assuming ρ ≤ 0.05. The relationship between the values of strength from handgrip and dynamic exercises were drawn by Pearson correlation. The results of the AMT to DPD (43.8 ± 6.8kgf), DPE (39.4 ± 7.7kgf), DED (44.9 ± 5.6kgf), and DEE (39.8 ± 8.3kgf). For the n-AMT in DPD (47.0 ± 3.0kgf), DPE (42.2 ± 6.1kgf), DED (49.2 ± 1.5kgf), and DEE (46.2 ± 4.1kgf). Significant difference was observed between DED and DEE. The strength tests of 1RM at bench press (73.2 ± 12.0kg and 82.0 ± 12.0kg), arm-curl (45.2 ± 8.9kg and 43.8 ± 8.9kg), triceps pulley (67.0 ± 6.3kg and 72.0 ± 6.3kg), and pulley (73.5 ± 8.5kg and 73.7 ± 7.5kg) for groups n-AMT and AMT did not showed differences. Correlations were showed between all handgrip tests and elbow flexor force for AMT, and between DPD and elbow extensor, abductor, adductor and extensor of shoulder for n-AMT. influences to the performance of the force dynamometry. It could be concluded that handgrip force and dynamic strength of upper limbs did not were putative responses for bull riding practice.

Efeitos agudos do exercício resistido, aeróbio contínuo e intervalado na pressão intraocular de indivíduos fisicamente ativos e normotensos

Apesar de pouco explorado, a prática de atividade física promove redução da Pressão Intraocular (PIO). O objetivo foi verificar o efeito de diferentes tipos de exercício na PIO. Quinze voluntários foram submetidos a 3 sessões de 30min de exercícios resistidos (3 x 8 repetições a 80%1RM), aeróbio contínuo (60% da Frequência Cardíaca de Reserva [FCR]), aeróbio intervalado (2min a 50% alternando com 1min a 80% da FCR). PIO foi mensurada antes (M1), durante (M2-15min), imediatamente após a sessão (M3) e na recuperação (5min [R1] e 10min [R2]). Como procedimento estatístico foi utilizado ANOVA. Houve redução da PIO nas 3 sessões de exercício (M2 e M3). Na recuperação, PIO permaneceu reduzida após 5min (R1) em todos os modelos. Porém, aos 10min (R2) estava menor que M1 apenas na sessão de exercício intervalado. Os resultados sugerem que o exercício intervalado é mais efetivo que o contínuo e resistido na redução da PIO.

Suplementação nutricional, pretensões e custo entre jovens do interior e litoral paulista experiêntes em treinamento resistido

Objective and closed questions were applied to 15 - 21 years old individuals under regular resistance exercise practice and self-reported nutritional supplements users, approaching training practices, type of substance feed and socioeconomic characteristics. The data were treated by frequency around the mean value. Major difference was observed to the goal of improvement in physical fitness (Guaruja 21% and Bauru 9.6%), close to the muscle hypertrophic enhancements (Guaruja 22% and Bauru 19.2%), and health proposes (17.3%), which was only reported in the country city. The monthly employment with supplements was observed to be close to one hundred Real, in both regions (Guaruja 79% and Bauru 80%). Even, based on different purposes, the supplements feed practice was closed to the goals, showing a reliable referential of use, but done without appropriated professional care.

Efeito agudo do exercício resistido, aeróbio contínuo e intervalado na pressão intraocular de indivíduos fisicamente ativos

Estudos sugerem que a atividade física promove redução e contribui no controle da Pressão Intraocular (PIO). O objetivo foi verificar o efeito de diferentes exercícios na PIO. Quinze voluntários foram submetidos a 3 sessões de 30min de exercícios resistidos (3 x 8 repetições a 80%1RM), aeróbio contínuo (60% da Frequência Cardíaca de Reserva [FCR]), aeróbio intervalado (2min a 50% alternando com 1min a 80% da FCR). PIO foi mensurada antes (M1), durante (M2-15min), imediatamente após a sessão (M3) e na recuperação (5min [R1] e 10min [R2]). Adotou-se ANOVA para tratamento estatístico. Houve redução significativa da PIO nas 3 sessões de exercício (M2 e M3). Na recuperação, PIO permaneceu reduzida após 5min (R1) em todos os modelos. Porém, aos 10min (R2) estava menor que M1 apenas na sessão de exercício intervalado. Os resultados sugerem que o exercício intervalado pode ser mais efetivo que o contínuo e resistido na diminuição da PIO.

Resposta crônica e aguda da glicemia a um protocolo de treinamento misto para melhora da saúde de diabéticos tipo 2

The objective of the research was to evaluate the effect of a training program of physical exercises mixed (aerobic / anaerobic conditioning circuit-break with active), including exercises, walking, weight training and Swiss ball, caused about possible changes in their metabolic system, as changes acute and chronic, individuals bearers of DM2. The methodology used is a model of experimented design of pretest and post-test applied to the group. The blood glucose levels were analyzed in fasting pre-test and post-test, and capillary glycemia in three periods of physical exercise: pre, during and post training, and the statistical processing done by the use of Statistical Software for PC-For SPSS ® Windows ®, V. 12.0 .. With the result has been a drop in the values significant glucometers between 6 weeks of training, with a negative delta average of 68 mg / dl. Furthermore, similar results were also found variations in the daily glycemic between the moments before and after the training session acute. Thus we find that, regardless of the biological mechanism responsible, the program mixed aerobic and anaerobic conditioning circuit-break with active was effective in reducing and controlling chronic and acute glycemic of subjects type 2 diabetic.

Aplicando o jogo Avançando com o resto no Ensino de Matemática

Como é conhecido pela maioria, infelizmente, o ensino de matemática vem enfrentando muitas dificuldades. Cerca o ensino dessa disciplina mitos, preconceitos, que fazem com que o estudante, muitas vezes, já chegue à escola com medo das aulas de matemática. Por outro lado, ainda perdura em muitas escolas um ensino focado na reprodução e não na construção do conhecimento, apesar de alguns professores buscarem alternativas para tornarem as aulas mais atrativas, priorizando atividades interessantes e motivadoras. O famoso livro didático e os caderninhos de apoio enviados pela secretaria do estado da educação ainda continuam sendo os principais recursos disponíveis na sala de aula. Os exercícios e listas, muitas vezes considerados intermináveis, buscam sem sucesso fixar um conhecimento que muitas vezes não foram se quer apropriado pelos alunos. Diante do exposto faz-se necessário pensar em transformações no ensino de matemática que ultrapassem a simples reprodução de exercícios e permitam tanto para o professor, quanto para o aluno um ensino mais atraente e desafiador e principalmente repleto de significados. Dessa forma, este estudo tem como objetivo mostrar ao aluno, a partir dos jogos matemáticos, a diversão e, também, a superação, possibilitando a construção de aprendizagens significativas.

Avaliação funcional pré e pós programa de exercício físico de pacientes em hemodialise

Model Study: An experimental study Introduction: Chronic Kidney Disease (CKD) refers to a syndromic diagnosis which leads to a progressive and irreversible loss of renal function. A hemodialysis patient may have limitations in functional capacity, pulmonary function and respiratory musclular strength impacting in quality of life. Objective: To evaluate the effects of an exercise program on pulmonary function, functional capacity, quality of life and pain in patients undergoing hemodialysis. Methodology: The study included 28 patients of both genders, women and men aged between 40 and 60 years undergoing dialysis at the Kidney Institute, Santa Casa de Misericordia in Presidente Prudente-SP. Primary outcomes included respiratory muscular strength measurements assessed by manovacuometry. The functional capacity was evaluated by a six minute walking test. A life quality questionnaire was applied to evaluate quality of life (SF36-KDQOL). Lung function was evaluated by spirometry. Pain was assessed by a visual analogue scale. The exercise program consisted of training 3 times a week for 40 minutes on hemodialysis during eight weeks. At the end of the program all patients were reassessed. Results: There was no significant difference in the values of FVC and FEV1 before and after the exercise program as well as the index Tiffenau. The value of post MIP was significantly higher than the value obtained in the pre program. For variable MEP no significant difference was found. Functional capacity evaluations showed that there were no significant differences (p> 0.05). The evaluation of quality of life, about the domains of specific areas of CKD showed statistical significance when comparing the list of symptoms and problems with overloading of renal disease and professional role. Indicators related to pain were significantly reduced after the program (P <0.05). Discussion: A chronic kidney patient faces complex situations of physical, social and financial aspects. Although no statistically significant results were found in all variables, the study corroborates to others found in the literature, which suggests that an exercise program can be positive for this population. Conclusion: Although lung capacity and functional capacity did not submit changes to the end of the study, reduced levels of pain, fatigue and dyspnea suggest improvement in functional performance after exercise programs.

Efeitos do treinamento misto na promoção da saúde e sua interferência no perfil lipidêmico em indivíduos diabéticos tipo 2

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.
