A história da imigração japonesa e seus descendentes: prática de atividade física e aspectos sócio-culturais.

O presente ensaio apresenta as práticas diferenciadas de atividade física e os aspectos sócio-culturais da população japonesa e descendentes residentes no Brasil para tentar compreender o motivo da manutenção da sua tradição cultural até os dias atuais. Para isto recorremos à trajetória dos imigrantes japoneses para o Brasil, como são suas práticas culturais, sociais e esportivas, e se a cultura foi um grande aliado para sua efetivação na sociedade brasileira. Concluímos que historicamente, a população japonesa manteve sua tradição ao longo do tempo com vistas a retornar a sua terra natal e apresentar-se bem perante os japoneses que ali ficaram. Com o tempo, muitos não conseguiram retornar ao Japão, a tradição continuou sendo mantida e a cultura japonesa muito cultivada. E as práticas esportivas e ginásticas seguiram nesta mesma direção

Incontinência urinária e exercício: descrição cinesiológica de uma proposta de intervenção

Research shows that symptoms of urinary incontinence are common among women who engage in physical activity. Objective: To conduct a kinesiological analysis of specific exercises for the pelvic floor muscles (PFM), proposing correspondences of these postures through resistance exercises. Methods:This research project is of a descriptive nature with level of evidence V. Videos and photos were taken to obtain an image for the collection of data based on the accomplishment of the specific postures. Results:The kinesiological study revealed that the muscles involved in the postures of exercises targeting the prevention of urinary incontinence beyond those specific to the pelvic floor were: trunk flexors; spinal erector; adductors and hip extensors. The resistance exercises corresponding to these positions in bodybuilding apparatus were the machine hack squat; sitting adductor exercises; sitting abductor exercises; the smith machine squat and the free squat or machine squat. Conclusion: This study showed that it is possible to construct correspondence between exercises for the pelvic floor muscles and resistance exercises with bodybuilding equipment and free weights. A new strategy is suggested for the physical education professional, based on resistance exercises: taking a coadjuvant approach to the treatment and prevention of urinary incontinence during physical and sports exercises255409412sem informaçãoPesquisas mostram que os sintomas da incontinência urinária são comuns entre mulheres que praticam atividade física.

PHYSICAL ACTIVITY LEVEL DOES NOT INFLUENCE THE NEUROMUSCULAR FATIGUE IN ADULTS

Introduction: Fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes and adaptations of the neuromuscular system. Objective: The purpose of this study was to evaluate the fatigue induced by intermittent successive extension of the knee between active and inactive university students. Method: Twenty healthy men (≥18 years), voluntarily participated in this study. To determine the maximum voluntary isometric contraction (MVIC) of the knee extensors muscle group, three sets of isometric contractions of knee extension were performed for five seconds with five minutes of rest between sets. The fatigue protocol consisted of 10 sets of 10 maximal concentric contractions of the extensor on the right knee, performed at 75% of MVIC with an interval of 45". Results: Significant reductions were observed (p<0.01), both in isometric strength (-34±4%) and the dynamic strength (-40 ± 3%). In addition, the slope of relationship strength x repetition was -0.79±0.07 Nm/repetitions and the magnitude of the effect reached -8.90. Conclusion: The protocol was useful to induce peripheral fatigue, although muscle strength is greater in the active group. In both isometric and dynamic action, muscle fatigue did not differ between groups

Influence of physical education on teachers of judo as a martial art

No ensino do Judô, o professor normalmente reproduz os ensinamentos de maneira similar ao que aprendeu, partindo do pressuposto de que é a maneira correta. No entanto, no que tange à busca de formação profissional, alguns professores de luta \ud realizam um curso formal em Educação Física para cumprir a legislação e a regulamentação das competências da profissão. Assim, o objetivo deste estudo é verificar a influência do curso de Educação Física em professores que lecionam Judô para \ud iniciantes. O estudo se deu por questões abertas. Participaram deste estudo 12 professores de Judô, faixa preta, sendo sete formados em Educação Física e cinco não formados. De acordo com os discursos obtidos, é possível concluir que a elaboração \ud das aulas de Judô se dá predominantemente a partir do conhecimento adquirido na vivência da modalidade do professor e a graduação em Educação Física pouco influenciou nas estratégias utilizadas.In the teaching of Judo, the teacher usually plays the teachings similarly to what has been learned, assuming that is the correct\ud way. However, when it comes to seeking professional training, some teachers struggle to carry out a formal course in Physical\ud Education to comply with the laws and regulations of acquiring the skills of the profession. The objective of this study\ud is to investigate the influence of Physical Education graduate courses for teachers who teach Judo for beginners. The study\ud used an open interviews. Participants were twelve teachers Judo fifth dan, seven graduates in Physical Education and five not\ud graduated. According to the results, we conclude that the development of Judo classes is predominantly from the knowledge\ud gained in the experience as an instructor and Physical Education graduation had little influence on the strategies use

Correlation of six-minute walking performance with quality of life is domain- and gender-specific in healthy older adults.

We analyzed the relationship between performance on the 6-min walk test (6MWT) and health-related quality of life (HRQoL) in older subjects. Our secondary aim was to determine the distance to be completed on the 6MWT for the subject to achieve a score of 50 on the Short Form (36) Health Survey (SF-36). Associations were tested using linear correlation and multivariate linear regression. Participants were 130 healthy older individuals. The predictive performance of the 6MWT based on an SF-36 score of 50 was assessed using a receiver operating characteristic curve and its area under curve (AUC). Associations were observed between physical functioning, role-emotional, social functioning, vitality, general health score, and 6MWT performance in women, after adjusting for confounding variables (coefficients: 0.57, 0.38, 0.40, and 0.46, respectively; p < 0.05). No association was found for men. The distance for the 6MWT to predict an SF-36 score of 50 was 481 m for men in the physical functioning (AUC: 0.79) and role-physical (AUC: 0.84) domains, and 420 m for women in role-emotional (AUC: 0.75), role-physical (AUC: 0.80), and general health (AUC: 0.80) domains. Our results indicate that superior 6MWT performance may be associated with better HRQoL in several domains in only healthy older women. No association between 6MWT performance and role-emotional, mental health, or vitality domains was found. We suggest that a score of 50 is represented by a 6MWT distance of 481 m for men and 420 m for women, at least in the role-physical domain

Functional Fitness and Self-Reported Quality of Life of Older Women Diagnosed with Knee Osteoarthrosis: A Cross-Sectional Case Control Study

Aim. Utilizing a cross-sectional case control design, the aim of this study was to evaluate the functional fitness and self-reported quality of life differences in older people diagnosed with knee osteoarthrosis (O) who participated in health promotion groups. Methods. Ninety older women were distributed into two groups: control without O of the knee (C, n=40) and a group diagnosed with primary and secondary knee O with grade II or higher, with definite osteophytes (OA, n=50). Functional fitness was evaluated by specific tests, and the time spent in physical activity and quality of life was evaluated by the IPAQ and WHOQOL (distributed in four domains: physical: P, psychological: PS, social: S, and environmental: E) domain questionnaires. Results. No differences were found between ages of groups (C: 66±7; OA: 67±9; years). The values of the chair stand test (rep) in the OA (13±5) group were different when compared to C group (22±5). For the 6-minute walk test (meters), the values obtained for the C (635±142) were higher (P<0.01) than the OA (297±143) group. The time spent in physical activity (min) was greater (P<0.001) in the control (220±12) group compared to OA (100±10) group. Higher values (P<0.001) in all domains were found in the C (P: 69±16, PS: 72±17, S: 67±15, E: 70±15) group compared to OA (P: 48±7, PS: 43±8, S: 53±13, E: 47±14) group. Conclusion. Our data suggests that knee O, in older women, can promote a decline in time spent performing physical activity and functional fitness with decline in quality of life with an increase in sitting time

Alterations in peak torque do not occur with hematological changes after muscle fatigue

ABSTRACT Introduction: Muscular fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes and adaptations of the neuromuscular system. Objective: The aim of this study was to analyze the changes in both peak torque and hematological parameters in active and inactive healthy subjects following a muscular fatigue protocol. Methods: Twenty-one healthy adult males performed a muscle fatigue protocol (10 sets, 10 repetitions of knee extension at 75% of the maximal isometric torque (MIT), 120º s-1 and 40 seconds of rest). Hematocrit (Ht), red blood cells (RBC) and leukocytes (L) analysis were evaluated before (B) and after (A) a fatigue test. Results: The inactive group presented impairment only in concentric muscular action of -41±4% in relation to the active (-23±3%) group. No differences were found in hematological parameters in inactive group (Ht, B: 45.00±0.01 vs. A: 47.00±0.01; RBC, B: 442±40 vs. A: 487±41; L, B: 7,565±2,878 vs. A: 8,015±4,224) and the active group (Ht, B: 45.00±0.63 vs. A: 47.00±0.01; RBC, B: 477±30 vs. A: 559±37; L, B: 6,418±3,557 vs. A: 6,632±4,460). Conclusion: Differences were found only in concentric actions between groups. Additionally, there were no relationships found in hematological parameters between groups.</jats:p
