ABSTRACT

SUMMARY OBJECTIVE: The aim of this work was to present hypotheses supporting capoeira as an activity aimed at health rehabilitation and maintenance of quality of life. METHODS: Capoeira players (n=245), residing in Brazil and abroad, were evaluated for quality of life (physical, social, psychological, and environmental domains from WHOQOL-bref). The capoeira players' quality of life scores were compared to normative values and reference values in martial arts. Besides, studies involving capoeira (Medline/Embase/Cinahl/SportDiscus) were also reviewed for health-related hypotheses, describing population, intervention, comparator, and outcome. RESULTS: There are hypotheses on capoeira improving health through (1) body composition, addressed by two studies investigating waist circumference, bone, and muscle mass; (2) functional capacity, investigated by three studies considering performance variables; (3) metabolism, in two studies demonstrating triglycerides and blood glucose reduction, and an enhancement of anaerobic glycolysis; and (4) cardiovascular parameters, addressed by two studies highlighting an increase in maximal oxygen consumption, heart rate, and rate of pressure product reduction, as well as an increase in parasympathetic activity at rest. The sample of this study had higher quality of life scores when compared to normative values for Brazilians, similar quality of life when it comes to social relationships, higher quality of life in the psychological and environmental domains, and lower quality of life in the physical domain when compared to practitioners of other combat sports/martial arts. CONCLUSION: An analysis of the impacts of capoeira resulted in hypotheses on the rehabilitation of players' biological health. Although the individuals were evaluated within the pandemic period, their quality of life domains were similar or superior to normative or reference values found by studies from before the pandemic.

ABSTRACT

O objetivo deste estudo foi verificar a associação entre o treinamento resistido (TR) e variáveis relacionadas com escores de ansiedade e depressão em mulheres brasileiras. Participaram do estudo 154 mulheres praticantes de TR (40,9±8,6 anos; 61,7±9,9 kg; 160,0±5,0 cm) e 113 mulheres não praticantes de exercício físico (Controle) (39,0±8,0 anos; 64,2±11,2 kg; 160,0±6,0 cm). As participantes responderam à Hospital Anxiety and Depression Scale e questões sociodemográficas relacionadas ao exercício físico. Diferenças estatísticas ocorreram entre os grupos em relação à ansiedade (TR: 0,75±0,48 vs. Controle: 1,07±0,57; P<0,001) e depressão (TR: 0,84±0,34 vs. Controle: 1,02±0,40; P<0,001). A frequência semanal de TR foi preditora de ansiedade [ß=-0,165; F(1,138)=6,39; P=0,05] e depressão [ß=-0,213; F(1,138)=6,46; P=0,01]. Conclui-se que mulheres brasileiras que praticam TR apresentam menores escores de ansiedade e depressão quando comparadas à não praticantes de exercício físico. Além disso, maior frequência semanal de TR prediz menores escores de ansiedade e depressão nesta população.


The aim was to verify the association between resistance training (RT) and related variables with anxiety and depression scores in Brazilian women. One hundred and fifty-four women practitioners of RT (40.9±8.6 years; 61.7±9.9 kg; 160.0±5.0 cm) and 113 non-practitioners (Control) participated in the study. Participants answered the Hospital Anxiety and Depression Scale and sociodemographic questions related to physical exercise. Statistical differences between groups occurred for anxiety (RT: 0.75±0.48 vs. Control: 1.07±0.57; P<0.001) and depression (RT: 0.84±0.34 vs. Control: 1.02±0.40; P<0.001). Weekly RT frequency significantly predicted anxiety [ß=-0.165; F(1.138)=6.39; P=0.05] and depression [ß=-0.213; F(1.138)=6.46; P=0.01]. We concluded that Brazilian women who practice RT presented lower anxiety and depression scores when compared to non-practitioners. In addition, a higher weekly frequency of RT predicted lower depression and anxiety scores in this population.

ABSTRACT

O exercício resistido (ER) pode reduzir a glicose no sangue em pessoas com diabetes tipo 2 (DM2). No entanto, é necessária maior clareza quanto à intensidade do ER e ao tempo necessário para essa resposta aguda. Portanto, o objetivo deste estudo foi comparar as respostas agudas de glicose no sangue no segundo dia de recuperação do ER moderada versus de alta intensidade em mulheres com DM2. Doze mulheres com DM2 (55,2 ± 4,0 anos; 70,1 ± 11,4 kg; e 155,7 ± 3,3 cm) realizaram duas sessões experimentais com sete dias de intervalo em ordem aleatória. Para a sessão 1: ER40% do teste de uma repetição máxima (1RM) e sessão 2: ER80%1RM, com 16 e 8 repetições para cada série, respectivamente, em 7 exercícios com 3 circuitos durante 40min. A glicemia foi monitorada por 35h (primeiro dia: 24h e segundo dia: 11h) a cada 5 minutos após cada sessão experimental pelo Sistema de Monitoramento Contínuo de Glicose (modelo Guardian REAL-Time). O teste t de Student não mostrou diferença significativa na glicemia do segundo dia (11h) após as sessões de ER40%1RM vs. RE80%1RM [respectivamente, 161,3 ± 62,3 mg.dL-1 vs. 157,2 ± 41,9 mg.dL-1; t (11) = 0,259; p = 0,800]. A ANOVA two-way para medidas repetidas mostrou que as respostas de glicose no sangue a cada hora durante a recuperação no segundo dia não mostraram diferenças significativas entre as sessões de ER [F (1,731; 19,039) = 0,688; p = 0,734]. Concluímos que as respostas glicêmicas agudas no segundo dia da recuperação do ER de intensidade moderada e alta não diferiram entre as mulheres com DM2.


Resistance exercise (RE) can lower blood glucose in people with type 2 diabetes (T2D). However, greater clarity is needed regarding the RE intensity and time required for this acute response. Therefore, the aim of this study was to compare acute blood glucose responses on the second day of recovery from moderate vs. high-intensity RE in women with T2D. Twelve women with T2D (55.2 ± 4.0 years; 70.1 ± 11.4 kg; and 155.7 ± 3.3 cm) performed two experimental sessions seven days apart in a randomized order. For session 1: RE40% of one-repetition maximum test (1RM) and session 2: RE80%1RM, with 16 and 8 repetitions for each set, respectively, in 7 exercises with 3 circuits during 40min. Blood glucose was monitored for over 35h (first day: 24h and second day: 11h) every 5 minutes after each experimental session by the Continuous Glucose Monitoring System (Guardian REAL-Time model). Student's t-test showed no significant difference in blood glucose on the second day (11h) after RE40%1RM vs. RE80%1RM sessions [respectively, 161.3 ± 62.3 mg.dL-1 vs. 157.2 ± 41.9 mg.dL-1; t (11) = 0.259; p = 0.800]. Two-way ANOVA for repeated measures showed that blood glucose responses every hour during recovery on the second day showed no significant differences between RE sessions [F (1.731, 19.039) = 0.688; p = 0.734]. We concluded that the acute blood glucose responses on the second day of moderate and high intensity RE did not differ among women with T2D.

ABSTRACT

ABSTRACT BACKGROUND: Meta-analyses have demonstrated that isometric handgrip training (IHT) decreases blood pressure in hypertensive individuals. Nonetheless, most studies were conducted in laboratory settings and its effects in real-world settings remain unclear. OBJECTIVE: To analyze the effects of IHT on office and ambulatory blood pressure in hypertensive patients attended within primary healthcare. DESIGN AND SETTING: Randomized controlled trial conducted in primary healthcare units within the Family Health Program, Petrolina, Pernambuco, Brazil. METHODS: 63 hypertensive patients (30-79 years old; 70% female) were randomly allocated into IHT or control groups. IHT was performed three times per week (4 x 2 minutes at 30% of maximal voluntary contraction, one-minute rest between bouts, alternating the hands). Before and after the 12-week training period, office and ambulatory blood pressure and heart rate variability were obtained. The significance level was set at P < 0.05 (two-tailed testing) for all analyses. RESULTS: IHT significantly decreased office systolic blood pressure (IHT: 129 ± 4 versus 121 ± 3 mmHg, P < 0.05; control: 126 ± 4 versus 126 ± 3 mmHg, P > 0.05), whereas there was no effect on diastolic blood pressure (IHT: 83 ± 3 versus 79 ± 2 mmHg, P > 0.05; control: 81 ± 3 versus 77 ± 3 mmHg, P > 0.05). Heart rate variability and ambulatory blood pressure were not altered by the interventions (P > 0.05 for all). CONCLUSION: IHT reduced office systolic blood pressure in hypertensive patients attended within primary care. However, there were effects regarding diastolic blood pressure, ambulatory blood pressure or heart rate variability. CLINICALTRIALS.GOV IDENTIFIER: NCT03216317.

ABSTRACT

SUMMARY: This study aimed to characterize the anthropometric profile and functional performance of elite competitors in different categories in the world championship of the ABADÁ-Capoeira School. Fifty high level male athletes were divided according to their weight categories, being: light category (VIOLA: ≤ 76.9 kg; n = 15); intermediate category (MEDIO: > 77.0 kg until ≤ 85.9 kg; n = 25) and heavy category (GUNGA: ≥ 86.0 kg; n = 10). Two evaluation batteries were performed: 1) anthropometry and somatotype determination; 2) physical performance in tests of push-up, sit-up, sit-and-reach, quadrant jump test, squat jump (SJ), and counter movement jump (CMJ). The "endo-mesomorph" classification predominated in the three categories. There was a difference in the quadrant jump test between VIOLA and GUNGA subgroups (F[2.47] = 4.299; p = 0.019). Endomorphism had a negative correlation (p < 0.01) with the performance in the sit-up (r = -0.51), push-up (r = -0.39), SJ (r = -0.45), and CMJ (r = -0.49). Male elite competitors at the international level, regardless the weight category, have a predominance of the mesomorphic component of the somatotype. Moreover, all capoeira athletes were classified as excellent for the sit-and-reach, sit-up, and push-up, and the latter were positively correlated with mesomorphism. However, endomorphism was inversely associated with the sit-up, push-up, SJ, and CMJ. In this way, the present study assists coaches in the formulation of appropriate training programs aiming the development of an ideal physical composition, which will be associated with high-level performance in capoeira.


RESUMEN: Este estudio tuvo como objetivo caracterizar el perfil antropométrico y el desempeño funcional de los competidores de élite en diferentes categorías en el campeonato mundial de la Escuela de Capoeira ABADÁ. Cincuenta deportistas masculinos de alto nivel se dividieron según sus categorías de peso: categoría ligera (VIOLA: ≤ 76,9 kg; n = 15); categoría intermedia (MEDIO: > 77,0 kg hasta ≤ 85,9 kg; n = 25) y categoría pesada (GUNGA: ≥ 86,0 kg; n = 10). Se realizaron dos baterías de evaluación: 1) antropometría y determinación del somatotipo; 2) rendimiento físico en pruebas de flexiones, abdominales, sentadillas y estiramientos, prueba de salto en cuadrante, salto en cuclillas y salto con contramovimiento. La clasificación "endo-mesomorfo" predominó en las tres categorías. Hubo una diferencia en la prueba de salto de cuadrante entre los subgrupos VIOLA y GUNGA (F [2,47] = 4,299; p = 0,019). El endomorfismo tuvo una correlación negativa (p <0.01) con el desempeño en los abdominales (r = - 0,51), lagartijas (r = -0,39), SJ (r = -0,45) y CMJ (r = - 0,49). Los competidores de élite masculinos a nivel internacional, indepen- dientemente de la categoría de peso, tienen predominio del componente mesomórfico del somatotipo. Además, todos los atletas de capoeira fueron clasificados como excelentes para sit-and-reach, sit-up y push-up, y estos últimos se correlacionaron positivamente con el MESO. Sin embargo, el ENDO se asoció inversamente con los abdominales, lagartijas, SJ y CMJ. De esta manera, el presente estudio ayuda a los entrenadores en la formulación de programas de entrenamiento adecuados que apunten al desarrollo de una composición física ideal, que estará asociada con un rendimiento de alto nivel en la capoeira.

ABSTRACT

Abstract A case report of six brown booby (Sula leucogaster) envenomation following the ingestion of toadfish (Porichthys porosissimus) specimens in Rio de Janeiro, Southeastern Brazil is discussed herein. Several macro- and microscopic pathological alterations were observed in the examined brown booby specimens, and rapid envenomation (<24 h) is suggested due to the digestion stage of the fish found in their gastrointestinal tracts. This is the first report to mention the death of adult and juvenile brown boobies due to envenomation by the toadfish P. porosissimus. Further studies assessing the role of discarded fish as a driving force of negative effects on seabirds, such as envenomations, for example, along the southeastern coast of Brazil are recommended.


Resumo Um relato de caso sobre o envenenamento de seis indivíduos de atobás-marrons (Sula leucogaster) após a ingestão de espécimes de mangagá-liso (Porichthys porosissimus) no Rio de Janeiro, sudeste do Brasil, é discutido neste estudo. Diversas alterações patológicas macro e microscópicas foram observadas nos espécimes de atobá-marrom examinados, e um envenenamento rápido (<24 h) é sugerido devido ao estágio de digestão dos peixes encontrados em seus tubos digestórios. Este é o primeiro registro que menciona a morte de indivíduos juvenis e adultos de atobás marrons por envenenamento devido a ingestão do magangá-liso P. porosissimus. Novos estudos avaliando o papel dos peixes descartados como uma força motriz dos efeitos negativos sobre as aves marinhas como, por exemplo, envenenamentos, ao longo da costa sudeste do Brasil são recomendados.

ABSTRACT

O objetivo do trabalho foi investigar o efeito agudo do óleo essencial de eucalipto (OEE) nas respostas cardiovasculares de repouso e após sessão de exercício resistido isométrico (ERI). Vinte idosos, após serem submetidos a sessões experimentais com inalação de OEE ou condição controle, permaneceram em recuperação durante 60 min (Rec-60') para depois realizaram três séries de 1 min (1 min de recuperação entre séries) no ERI, para membro superior dominante em aparelho de preensão manual, com intensidade de 30% da contração voluntária máxima (ERI-30%). Intervalos R-R (iRR) e medidas no domínio da frequência (low frequency ­ LF e high frequency ­ HF) além da pressão arterial (PA), frequência cardíaca (FC) e duplo produto (DP) foram avaliados. Não ocorreram diferenças (p>0,05) quando comparadas as sessões (OEE vs.controle) na Rec-60' e ERI-30%. Diferenças foram encontradas no fator tempo do repouso para Rec-60' nas variáveis FC e iRR e do repouso para ERI-30% na PA sistólica, PA diastólica e DP. A inalação do OEE não proporcionou alterações significativas nas respostas cardiovasculares e autonômicas de idosos no repouso e após sessão de ERI-30%.


The aim was to investigate the acute effect of eucalyptus essential oil (EEO) in cardiovascular responses of rest and after isometric resistance exercise (IRE). Twenty elderly individuals, after being submitted to experimental sessions with inhalation of EEO or control condition, remained in recovery for 60 min (Rec-60') and then performed three sets of 1 min (1 min recovery between sets) in IRE, for dominant upper limb in handgrip, with intensity of 30% of maximum voluntary contraction (IRE-30%). R-R intervals (RRi) and measurements in the frequency domain (low frequency ­ LF and high frequency ­ HF) in addition to blood pressure (BP), heart rate (HR) and rate product pressure (RPP) were evaluated. There were no differences (p>0.05) when comparing the sessions (EEO vs.control) in Rec-60' and IRE-30%. Differences were found in the time factor of rest to Rec-60' in HR and RRi variables and of rest to IRE-30% in systolic BP, diastolic BP and RPP. Inhalation of EEO did not provided significant changes in cardiovascular and autonomic responses on rest and after IRE-30% in elderly individuals.

ABSTRACT

ABSTRACT Introduction Adequate measurement of movement velocity in strength exercises can assist in the prescription and evaluation of training effects. Objective The objectives of the present study were to analyze the reliability (test-retest) and concurrent validity of the movement velocity measured by means of the electrogoniometer and accelerometer during horizontal leg press exercise at different intensities (40, 60, 80% of a maximum repetition - 1RM). Methods Eighteen young women attended the laboratory on five occasions. After determining the maximum dynamic force, two visits (separated by 48-72 hours) were used to verify the reliability (test-retest) for different speed variables in the three intensities. Results The mean propulsive velocity obtained by the goniometer showed higher Intraclass correlation coefficients (ICC) and lower coefficients of variation compared to the accelerometer. The same behavior was observed for both the mean velocity and the peak velocity. The propulsive time was more reproducible and with less variation for the accelerometer and bad CCI for both sensors were observed at 60% of 1RM. When the sensors are compared, the mean and average propulsive velocities presented moderate ratios with a large to very large standardized medium bias. Conclusion The potentiometer of the electrogoniometer can be used to estimate the velocity in the horizontal leg press exercise, especially for loads of 60 and 80%. The performance of the accelerometer was inferior to that of the potentiometer. Level of evidence II; Diagnostic studies.


RESUMO Introdução A adequada mensuração da velocidade de movimento nos exercícios de força muscular pode auxiliar na prescrição e avaliação dos efeitos do treinamento. Objetivo Os objetivos do presente estudo foram analisar a confiabilidade (teste-reteste) e validade concorrente da velocidade de movimento mensurada por meio do eletrogoniômetro e acelerômetro durante exercício leg press horizontal em diferentes intensidades (40, 60, 80% de uma repetição máxima - 1RM). Métodos Dezoito mulheres jovens compareceram ao laboratório em cinco ocasiões. Após determinação da força dinâmica máxima, duas visitas (separadas por 48-72 horas) foram destinadas a verificação da confiabilidade (teste-reteste) para diferentes variáveis de velocidade nas três intensidades. Resultados A velocidade média propulsiva obtida pelo goniômetro apresentou maiores coeficientes de correlação Intraclasse (CCI) e menores coeficientes de variação em comparação ao acelerômetro. O mesmo comportamento foi verificado tanto para a velocidade média quanto a pico. O tempo propulsivo foi mais reprodutível e com menor variação para o acelerômetro e CCI ruins para ambos os sensores foram observados em 60% de 1RM. Quando os sensores são comparados, a velocidade média e média propulsiva apresentaram relações moderadas com viés médio padronizado grande a muito grande. Conclusão O potenciômetro do eletrogoniômetro pode ser utilizado para estimar a velocidade no exercício leg press horizontal, em especial, para cargas de 60 e 80%. O desempenho do acelerômetro se mostrou inferior ao do potenciômetro. Nível de evidência II; Estudos diagnósticos.

ABSTRACT

Anaplastic oligodendrogliomas (AOs) correspond to 23% of all oligodendrogliomas. They correspond to a tumor with malignant histological characteristics, focal or diffuse, associated with a worse prognosis. In the present case report, we describe the case of a 30-year-old female submitted to resection of a right parietal lesion whose histology showed to be an AO. She underwent complementary treatment with chemotherapy and radiotherapy according to the Roger Stupp protocol. Four years after the initial diagnosis, there was tumor recurrence within the superior sagittal sinus, with no evidence of recurrence elsewhere. In the literature, we have found no similar published case reinforcing the rarity of this condition.

ABSTRACT

Abstract Hemodynamic and autonomic responses have been used as sensitive indicators of cardiovascular health in situations involving emotions. However, few studies evaluated these indicators when feelings result from vicarious experiences. This research aimed to verify if empathy measures would be associated with variations in blood pressure, heart rate, rate pressure product, and heart rate variability in young adults, after exposure to experimental situations. Results point out that hemodynamic and autonomic cardiac indicators were associated with dispositional and situational empathy. These results are discussed based on Martin Hoffman's theory and in the light of recent findings in the field of Psychophysiology.


Resumo Respostas hemodinâmicas e autonômicas têm sido utilizadas como indicadores sensíveis da saúde cardiovascular durante situações de cunho emocional. Todavia, ainda são escassos os trabalhos que avaliam esses indicadores quando os sentimentos produzidos ocorrem a partir de experiências vicárias. O presente estudo objetivou verificar se medidas de empatia estariam associadas a variações nos indicadores de pressão arterial, frequência cardíaca, duplo produto e variabilidade da frequência cardíaca em jovens adultos, após sua exposição a situações-estímulo. Os resultados indicam que indicadores hemodinâmicos e autonômicos cardíacos estiveram associados a componentes da empatia situacional e da empatia constitucional. Estes resultados são discutidos com base na teoria de Martin Hoffman e a partir de achados recentes no campo da Psicofisiologia.

ABSTRACT

Introdução: Os telômeros estão localizados nas extremidades dos cromossomos e constituem-se de sequências do DNA e proteínas associadas. O exercício físico parece ter relação com um maior comprimento de telômeros, porém, pouco se sabe sobre o impacto deste na dinâmica telomérica de pessoas com disfunções crônico-degenerativas. Objetivo: Revisar sistematicamente a literatura a respeito do efeito do exercício no comprimento dos telômeros em pessoas com disfunções crônico-degenerativas. Métodos: Foram realizadas buscas por dois investigadores independentes nas bases de dados Pubmed, Scopus, Lilacs e Cochrane Controlled Trials Database, analisando publicações nos idiomas inglês e português. Resultados: Foram encontrados 845 estudos, onde destes, quatro atenderam aos critérios de elegibilidade e seguiram para síntese. Conclusão: Embora o encurtamento dos telômeros esteja relacionado ao estilo de vida, herança genética e doenças do envelhecimento, ainda não está claro se o exercício físico pode atenuar tal processo de encurtamento de forma significativa em indivíduos com disfunções crônico-degenerativas, como excesso de peso e diabetes.


Introduction: Telomeres are located at the ends of chromosomes and consist of DNA sequences and associated proteins. Physical exercise seems to be related to a greater telomeres length, but little is known about its impact on the telomere dynamics of people with chronic degenerative dysfunctions. Purpose: Systematically review the literature on the effect of exercise on the telomeres length in people with chronic degenerative disorders. Methods: Searches were carried out by two independent researchers in the databases Pubmed, Scopus, Lilacs e Cochrane Controlled Trials Database, analyzing publications in the English and Portuguese language. Results: A total of 845 studies were found, of which four met the eligibility criteria and followed up for synthesis. Conclusion: Although shortening of telomeres is related to lifestyle, genetic inheritance, and diseases of aging, still unclear physical exercise can attenuate such a shortening process significantly in individuals with chronic-degenerative dysfunctions such as overweight and diabetes.

ABSTRACT

Abstract AIMS The present study aimed to investigate the effects of whole body isometric resistance training (IRT) on blood pressure (BP), strength and aerobic fitness. We also analyzed whether the effects of whole body isometric training compares to whole body dynamic resistance training (DRT). METHODS Twenty-nine pre-hypertensive sedentary males, aged between 40 and 60 years were divided into three groups: IRT (n = 10), DRT (n = 9), and Control (n = 10). Both programs involved whole body resistance training, and occurred for 12 weeks, three times/week, at an intensity of 60% of a dynamic one repetition maximum test (1RM). Before and after 12 weeks, 24 hours blood pressure monitoring, 1RM strength and aerobic fitness were assessed. RESULTS IRT reduced diastolic BP values during a 24-hour period and daytime. There was also a decrease in mean BP values during daytime (P<0.05). No interaction between time and group in systolic BP, diastolic BP, mean BP, heart rate and arterial stiffness index were observed (P>0.05). IRT increased strength and aerobic fitness when compared to Control group. However, these changes were lower than DRT regarding strength (DRT: ∆ = 43.1±10.6% vs. IRT: ∆ = 24.1±7.1% vs. CON: Δ = 4.2±11.5%; P<0.05) and aerobic fitness (DRT: ∆ = 22.9±10.7% vs. IRT: ∆ = 12.9±6.1% vs. CON: Δ = -2.1±7.4%; P<0.01). CONCLUSION Whole body IRT reduced diastolic BP and mean BP, however, the decrease was not different for the DRT group. IRT also increased strength and aerobic fitness, nevertheless, these changes were lower than after DRT.

ABSTRACT

Devido à diversidade existente entre grupos de Capoeira, um fator de confusão relacionado à nomenclatura cerca o campo acadêmico. Com isso, a partir de um estudo descritivo e trans-versal, objetivou-se analisar a nomenclatura básica da Capoeira entre diferentes grupos. A descrição da nomenclatura foi a partir do referencial de uma aula básica programada de Capo-eira (ABPC). Foi realizada entrevista (questionário contendo figuras de 23 movimentos da ABPC) com um integrante graduado de cada um dos cinco grupos a seguir: G1: IUNA; G2: ABADÁ; G3: BRASIL; G4: BERIBAZU; G5: CENTRO IDEÁRIO. Diferenças entre grupos ocorreram no nome de 13 movimentos analisados (56,5%). Na classificação destes, verificou-se uma parcial concordância entre G1 a G4, enquanto que o G5 diferenciou-se dos demais.


Due to the Capoeira diversity among groups, a confounding factor related to nomenclature surrounds the academic field. Thus, from a descriptive and transversal study, the aim of this study was to analyze the basic nomenclature of Capoeira among different groups. The de-scription of the nomenclature was based on the reference of a basic programmed lesson of Capoeira (BPLC). An interview was conducted (questionnaire containing figures from 23 movements of BPLC) with a graduated member from each of the following five groups: G1: IUNA, G2: ABADÁ, G3: BRASIL, G4: BERIBAZU, G5: CENTRO IDEÁRIO. Differences among groups occurred in the name of 13 movements (56.5%). In the classification of these, a partial concordance among G1 to G4 was verified, whereas the G5 differentiated from the others.

ABSTRACT

Introdução: A hipotensão pós-exercício é definida como uma redução da pressão arterial, após uma única sessão de exercício, para valores abaixo dos observados no repouso pré-exercício. Objetivo: Revisar sistematicamente a literatura quanto ao efeito dos intervalos de recuperação entre séries na hipotensão pós-exercício resistido. Métodos: Foram realizadas buscas por dois investigadores independentes nas bases de dados Pubmed, Scopus e Cochrane Controlled Trials Database. Resultados: Foram encontrados 570 estudos entre 1980 e 2016, onde destes, 6 atenderam os critérios de elegibilidade. Conclusão: O intervalo de recuperação de 120 segundos entre séries parece promover maior duração e magnitude na hipotensão pós-exercício resistido quando adotado o método convencional. Por outro lado, quando o método circuitado foi realizado, 30 a 40 segundos de intervalo de recuperação entre séries podem ser importantes na indução da hipotensão pós-exercício resistido de pressão arterial sistólica. (AU)


Introduction: The post-exercise hypotension is defined as a reduction in blood pressure to values below those observed in the pre-exercise rest. Objective: To review systematically the literature regarding the effect of the recovery intervals between sets on post-resistance exercise hypotension. Methods: Two independents investigators performed search on Pubmed, Scopus and the Cochrane Controlled Trials Database. Results: Were found 570 studies between 1980 and 2016, where of these, 6 met the eligibility criteria. Conclusion: The recovery interval of 120 seconds between sets appears to promote greater duration and magnitude in post-resistance exercise hypotension when adopted the conventional method. On the other hand, when the circuited method is performed, 30 to 40 seconds of recovery interval between sets may be important in the induction of post-resistance exercise hypotension of systolic blood pressure.

ABSTRACT

Meta-analytical studies have indicated that isometric handgrip training promotes significant reduction in blood pressure in hypertensive patients with similar or greater decreases in blood pressure than observed after aerobic and dynamic resistance training. However, several gaps in the literature still need to be addressed. Thus, we designed the ISOPRESS network group, which consists of a task force of different research groups aimed at analyzing the effects of isometric handgrip training on different contexts, parameters, and populations. Thus, the aim of this study was to describe the rationale and design behind the ISOPRESS, presenting the methods employed. The ISOPRESS questions involve whether isometric handgrip training is effective in hypertensives in different settings (ISOPRESS 1 - unsupervised training and ISOPRESS 2 - public health system), whether it works in patients with other cardiovascular diseases (ISOPRESS 3 - obstructive sleep apnea and ISOPRESS 4 - peripheral artery disease) and what are the mechanisms underlying the effects of isometric handgrip training in hypertensives (ISOPRESS 5 - neural mechanism). The study will yield information on the effectiveness of isometric handgrip training in different settings and patients with other cardiovascular diseases. Finally, it will help to understand the mechanisms involved in reducing blood pressure in hypertensives.(AU)

ABSTRACT

Resumo Verificar as respostas de 24 horas da pressão arterial (PA) em jovens adultos após diferentes ordens de execução do exercício aeróbio (EA) e resistido (ER). Participarão do estudo dez homens saudáveis (22,6 ± 70,3; 3.7 anos ± 5,8 kg; 175,9 ± 5,8 centímetros). O estudo consistiu em quatro sessões experimentais realizadas de forma aleatórias: EA + ER (AR); ER + EA (RA); Circuito Concorrente (CC) e controle (CO). Todas as sessões tiveram a mesma duração e intensidade, EA: 15 min a 90% do limar de lactato mínimo indireto; ER: 15min a 90% de 12 RM com 12 repetições (seis exercícios). A PA foi medida antes, durante e 1 h (Microlife® BP3A1C) após a realização de exercícios em laboratório e 23 h durante as atividades diárias, utilizando a medição da pressão arterial ambulatorial (Dyna-MAPA®). A pressão arterial sistólica (PAS) no período de 24 horas e de vigília, e a diastólica (PAD), no período de 24 horas, o sono e de vigília, e a média da PA no período de vigília foram menores na sessão RA em comparação com a sessão CO apresentando um tamanho do efeito de moderado a alto (d de Cohen = -0,46 / -0,78). A área sob a curva da PAD na sessão AR foi menor do que na sessão CO no período de vigília (1004 ± 82 vs. 1065 ± 107; p < 0,047) e 24 h (1456 ± 103 vs 1528 ± 132 < 0,026) períodos. A sessão RA apresentou maiores pontos de redução da PA durante 24 horas em relação ao outros protocolos.(AU)


Abstract To verify 24-hour blood pressure (BP) responses in young adults after different orders of aerobic (AE) and resistance exercises (RE). Anaerobic threshold (AT) and strength (12 RM) were evaluated in ten healthy men (22.6 ± 3.7yrs; 70.3 ± 5.8 kg; 175.9 ± 5.8 cm). Four experimental sessions: Aerobic + Resistance (AR); Resistance + Aerobic (RA); Concurrent circuit (CC) and control day (CO) were randomly performed. All sessions had the same duration and intensity, AE: 15 min at 90% of AT; ER: 15 min at 90% of 12 RM with 12 reps (6 exercises). BP was measured before, during and 1 h (Microlife® BP3A1C) after performing exercises in the laboratory and 23 h during daily activities using ambulatory blood pressure measurement (Dyna-MAPA®). Systolic BP (SBP) in 24 h and awake periods, and Diastolic BP (DBP) in 24 h, sleep and awake periods, and Mean BP in awake period were lower in RA session compared with CO session with moderate to high effect size (d de Cohen = -0.46/-0.78). The DBP area under the curve in RA was lower than CO in awake (1004 ± 82 vs. 1065 ± 107; p < 0.047) and 24 h (1456 ± 103 vs. 1528 ± 132; p < 0.026) periods. The SBP delta were lower in RA at 0-1 h (-12.0 mmHg), 2-3h (-16.5 mmHg), 6-7 h (-19.4 mmHg) and 10-11 h (-13.0 mmHg) compared with CO; lower in AR at 4-5h (-19.2 mmHg) and 6-7 h (-20.2 mmHg) compared with CO; and lower in CC at 2-3h (-15.6 mmHg) and 6-7 h (-17.5 mmHg) compared with CO. The DBP was lower at 4-5 h (-14.0 mmHg) in RA compared with CO. After performing RA exercises, there were greater decreases in BP during 24 h in young adults.(AU)

ABSTRACT

Abstract The aim of this study was to compare body adiposity indexes and to identify cutoff values in the prediction of disability in older women. Eighty-seven volunteers (67.27±6.45 years) underwent body composition assessment using dual-energy X-ray absorptiometry (DXA) and had five anthropometric indexes measured (Waist Circumference, WC; Waist-to-Height Ratio, WHtR; Body Mass Index, BMI; Body Adiposity Index, BAI; and conicity index). Functionality was assessed from three Senior Fitness Test Battery protocols: 30-second chair stand, 8-foot up-and-go, and 6-minute walk. Pearson’s correlation was conducted to identify the relationship between body adiposity indexes and functionality results. Cutoff values to predict disability were obtained from ROC curves and odds ratio were calculated for the same outcome. Disability prevalence was 36.8%. Scores in the 30-second chair stand, 8-foot up-and-go, and 6-minute walk tests showed stronger associations with WC (r=-0.345; p<0.01), WHtR (r=-0.417; p<0.01) and BAI (r=0.296; p<0.01), respectively. The cutoff values identified were 89.5cm, 39.2%, 26.93kg/m2, 34.6%, 0.51cm and 1.23 for WC, DXA-derived body fat percentage, BMI, BAI, WHtR and conicity index, respectively. WC showed greater odds ratio for disability outcome (odds ratio: 3.16; CI: 1.3–7.8). WC showed strong relationship with functional tests and its cutoff values exhibited predicting skill for disability in older women.


Resumo Objetivou-se comparar índices de adiposidade corporal e identificar pontos de corte na predição de incapacidade funcional em mulheres idosas. Oitenta e sete voluntárias (67,27±6,45 anos) foram submetidas à avaliação de composição corporal através de Dual energy x-ray absorptiometry (DXA), e tiveram cinco índices antropométricos mensurados (perímetro de cintura, PC; relação cintura estatura, RCE; índice de massa corporal, IMC; índice da adiposidade corporal, IAC; e índice de conicidade). A funcionalidade foi avaliada a partir de três protocolos da Senior Fitness Test Battery: sentar e levantar em 30 segundos; 8-foot up-and-go; e caminhada de seis minutos. A correlação de Pearson foi conduzida para identificar o relacionamento entre as medidas de adiposidade corporal e os resultados de funcionalidade. Foram obtidos pontos de corte para incapacidade funcional a partir de curvas ROC, e o odds ratio foi calculado para o mesmo desfecho. A prevalência de incapacidade funcional foi de 36,8%. Os escores dos testes sentar e levantar em 30 segundos, caminhada de seis minutos e 8-foot up-and-goapresentaram associações mais consistentes para PC (r=-0,345; p<0,01), RCE (r=-0,417; p<0,01) e IAC (r=0,296; p<0,01), respectivamente. Os pontos de corte identificados foram 89,5cm, 39,2%, 26,93kg/m2, 34,6%, 0,51cm e 1,23, para PC, percentual de gordura medido pelo DXA, IMC, IAC, RCE e índice de conicidade, respectivamente. O PC apresentou maior razão de chances para incapacidade funcional (odds ratio:3,16; IC:1,3–7,8). O PC apresentou associação mais consistente com os testes funcionais e seus valores de corte exibiram habilidade preditora para incapacidade em mulheres idosas.

ABSTRACT

Abstract The aim of this study was to examine the reliability of the 6-minute walk test (6MWT) and post-exercise cardiac autonomic markers in physically active and sedentary older women. Eighteen physically active older women (64.2±3.1 years; 63.0±2.7 kg; 1.52±0.06 m; 26.9±2.7 kg.m-2) who performed Tai Chi Chuan for at least 6 months, and 18 sedentary older women (64.0±3.7 years; 63.8±8.9 kg; 1.49±0.05 m; 28.4±3.5 kg.m-2) were submitted to 6MWT in two separate occasions. Immediately after 6MWT, heart rate recovery at one (HRR1’) and two minutes (HRR2’), as well as the heart rate variability (HRV) were recorded. Reliability was verified by intraclass correlation coefficient (ICC) with 95% confidence interval, Bland-Altman plots were used as a measure of agreement, and coefficient of variation (CV) was calculated. High reliability (ICC=0.86) was found for performance in 6MWT (528.8 ± 71.4 m and 473.2 ± 62.4 m; CV=7.9 and VC=8.5%) in both groups. Likewise, high reliability (ICC≥0.84 and ICC≥0.80) was found for HRR 1’ (29.0±11.0 bpm and 17.0±8.0 bpm; VC=30.1% and VC =40.2%) and HRR 2’ (36.0±10.0 bpm and 24.0±9.0 bpm; VC =23.7% and VC =22.8%) in both groups. Regarding HRV, moderate reliability was found in the active group (CCI≥0.57; VC =35-47%), while moderate-high reliability was found in the sedentary group (CCI=0.65-0.76; VC=34-69%). Agreement was found for all variables analyzed. In conclusion, post-exercise 6MWT, HRR, and HRV are reliable tools to assess functional capacity and cardiac autonomic control in physically active and sedentary older women.


Resumo Objetivou-se verificar a reprodutibilidade do teste de caminhada de 6 minutos (TC6) e de marcadores autonômicos cardíacos pós-esforço em idosas fisicamente ativas e sedentárias. Dezoito idosas ativas (64,2 ± 3,1 anos; 63,0 ± 2,7 kg; 1,52 ± 0,06 m; 26,9 ± 2,7 kg.m-2) praticantes de Tai Chi Chuan (≥6 meses de prática) e 18 idosas sedentárias (64,0 ± 3,7 anos; 63,8 ± 8,9 kg; 1,49 ± 0,05 m; 28,4 ± 3,5 kg.m-2) foram submetidas a dois TC6 com uma semana de intervalo. Foram medidas a frequência cardíaca de recuperação (FCR) de um e dois minutos (FCR1’ e FCR2’, respectivamente) e variabilidade da frequência cardíaca (VFC) pós-esforço. A reprodutibilidade foi verificada pelos: coeficiente de correlação intraclasse (CCI) com 95% de intervalo de confiança; análise de concordância de Bland-Altman; e coeficiente de variação (CV). O desempenho no TC6 (528,8±71,4 m e 473,2±62,4 m; CV=7,9% e CV=8,5%) apresentou alta reprodutibilidade (CCI=0,86) em idosas ativas e sedentárias, respectivamente. Similarmente, as medidas pós-esforço da FCR1’ (29,0±11,0 bpm e 17,0±8,0 bpm; CV=30,1% e CV=40,2%) e FCR2’ (36,0±10,0 bpm e 24,0±9,0 bpm; CV=23,7% e CV=22,8%) apresentaram alta reprodutibilidade (CCI≥0,84 e CCI≥0,80) em ambos os grupos. Quanto a VFC verificou-se reprodutibilidade moderada (CCI≥0,57; CV=35-47%) em idosas ativas e moderada-alta nas sedentárias (CCI=0,65-0,76; CV=34-69%). Todas as variáveis apresentaram concordância em ambos os grupos. Conclui-se que o TC6, FCR e VFC pós-esforço são instrumentos reprodutíveis na avaliação da capacidade funcional e controle autonômico cardíaco em idosas ativas e sedentárias.
