ABSTRACT

ABSTRACT Background: Kidney failure reduces life expectancy by one-third compared with the general population, and cardiovascular complications and poor cardiorespiratory fitness (CRF) are the main causes. We aimed to evaluate the association between severely low CRF and all-cause mortality risk in HD patients. Methods: This observational prospective cohort study followed-up patients receiving HD from August 2015 until March 2022. Cardiorespiratory fitness was evaluated through the cardiopulmonary exercise test, and the peak oxygen uptake (VO2peak) value was used to determine severely low CRF (< 15 mL∙kg−1∙min−1). Cox regression and univariate Kaplan-Meier analysis were used to evaluate the association of severely low CRF with mortality risk and survival rate. Results: Forty-eight patients were followed-up for a median of 33.0 [14.3 - 49.3] months. A total of 26 patients had severely low CRF. During the follow-up period, 11 patients (22.92%) died from all causes. From these, eight (30.8%) had severely low CRF. Even so, severely low CRF was not associated with crude death rates for patients stratified by CRF levels (p = 0.189), neither in unadjusted (HR 2.18; CI 95% 0.58−8.23) nor in adjusted (HR 1.32; CI 95% 0.31−5.59) Cox proportional hazard models. As a continuous variable, VO2peak was not associated with mortality risk (HR 1.01; CI 95% 0.84−1.21). Univariate Kaplan-Meier analysis showed that patients with severely low CRF did not have significantly worse survival rates than those with mild-moderate CRF (p = 0.186). Conclusion: Our findings indicated that severely low CRF was not associated with all-cause mortality in patients on HD. Despite severely low CRF being prevalent, larger cohort studies are needed to establish strong conclusions on its association with all-cause mortality.


RESUMO Introdução A insuficiência renal reduz a expectativa de vida em um terço comparada à população em geral. Complicações cardiovasculares e baixa aptidão cardiorrespiratória (ACR) são as principais causas. Avaliamos a associação entre ACR muito baixa e risco de mortalidade por todas as causas em pacientes em HD. Métodos Este estudo de coorte prospectivo observacional acompanhou pacientes em HD de agosto/2015 a março/2022. Avaliou-se a aptidão cardiorrespiratória pelo teste de exercício cardiopulmonar, e o valor do pico do consumo de oxigênio (VO2pico) foi usado para determinar ACR muito baixa (< 15 mL∙kg−1∙min−1). Utilizamos regressão de Cox e análise univariada de Kaplan-Meier para avaliar associação da ACR muito baixa com o risco de mortalidade e taxa de sobrevida. Resultados Acompanhamos 48 pacientes por uma média de 33,0 [14,3 - 49,3] meses. Um total de 26 pacientes apresentaram ACR muito baixa. No período de acompanhamento, 11 pacientes (22,92%) foram a óbito por todas as causas. Destes, oito (30,8%) apresentavam ACR muito baixa. Mesmo assim, ACR muito baixa não foi associada a taxas brutas de mortalidade para pacientes estratificados por níveis de ACR (p = 0,189), nem em modelos de risco proporcional de Cox não ajustados (HR 2,18; IC 95% 0,58-8,23) ou ajustados (HR 1,32; IC 95% 0,31-5,59). Como variável contínua, VO2pico não foi associado ao risco de mortalidade (HR 1,01; IC 95% 0,84-1,21). A análise univariada de Kaplan-Meier mostrou que pacientes com ACR muito baixa não apresentaram taxas de sobrevida significativamente piores do que aqueles com ACR leve-moderada (p = 0,186). Conclusão Nossos achados indicaram que a ACR muito baixa não foi associada à mortalidade por todas as causas em pacientes em HD. Apesar de ACR muito baixa ser prevalente, são necessários estudos de coorte maiores para estabelecer conclusões sólidas sobre sua associação com mortalidade por todas as causas.

ABSTRACT

El propósito del estudio fue cuantificar el tamaño de efecto (TE) del ejercicio aeróbico sobre la capacidad cardiorrespiratoria en sobrevivientes de la enfermedad COVID-19, producida por el virus SARS-CoV 2. Se revisaron dos bases de datos (EBSCO host y PubMed) entre los meses de agosto a noviembre del año 2021. Se encontraron 142 656 posibles artículos y, luego de varios filtros, se incluyeron 9 estudios que cumplían los requisitos de inclusión. Se usó el modelo de efectos aleatorios. Se obtuvieron 12 TE en un primer meta-análisis que tuvo sesgo (según prueba de Egger). Tras identificar y eliminar grupos con TE extremo, se obtuvo un modelo corregido y sin sesgo con 7 estudios y 9 TE, donde se encontró que el ejercicio aeróbico tiene un efecto significativo, positivo y de magnitud grande sobre la condición cardiorrespiratoria en sobrevivientes a la enfermedad de COVID-19 (TE = 0.849; IC95%: 0.715 - 0.982; . = 7.13; . = 0.522; I. = 0.87%; Egger . = 0.205). Las intervenciones con ejercicio aeróbico favorecen la mejora de la capacidad cardiorrespiratoria en pacientes sobrevivientes de COVID-19. Dos estudios aplicaron solo ejercicio aeróbico, mientras que los otros siete combinaban aeróbico con ejercicio de fuerza y otras modalidades. En todos los casos se tuvo TE significativo. Finalmente, estos resultados fueron relativamente homogéneos, sin evidenciar la influencia de posibles variables moderadoras.


The purpose of this study was to quantify the effect size (TE) of aerobic exercise on cardiorespiratory capacity in survivors of the COVID-19 disease caused by the SARS-CoV 2 virus. Two data bases (EBNSCO host and PubMed) were reviewed over the months of August through November, 2021. A total 142 656 potential articles were reviewed and, after applying several filters, 9 studies that met the requirements for inclusion were included. The random effect model was used. A first meta-analysis that was biased (according to Egger test) obtained 12 TE. After identifying and eliminating groups with an extreme TE, a corrected, unbiased model was obtained with 7 studies and 9 TE was obtained, where it was found that aerobic exercise has a significant, positive and large-magnitude effect on the cardiorespiratory condition on survivors of the COVID-19 disease (TE = 0.849; IC95%: 0.715 - 0.9 82; Q = 7.13; p = 0.522; I2 = 0.87%; Egger p = 0.205). Interventions with aerobic exercise foster an improvement in cardiorespiratory capacity in patients who survived COVID-19. Two studies applied aerobic exercise only, whereas the other seven combined aerobic exercise with strength exercise and other modes. In all cases, a significant TE was obtained. Finally, these results were relatively homogeneous, with no evidence for the influence of possible moderating variables.


O objetivo do estudo foi quantificar o tamanho do efeito (TDE) do exercício aeróbico na aptidão cardiorrespiratória em sobreviventes da doença COVID-19, produzida pelo vírus SARS-CoV 2. Foram revisadas duas bases de dados (EBSCO host e PubMed) entre agosto e novembro de 2021. Foi encontrado um total de 142.656 artigos em potencial e, após vários filtros, foram incluídos 9 estudos que atendiam aos requisitos de inclusão. Foi usado o modelo de efeitos aleatórios. Foram obtidos 12 TDE em uma primeira metanálise que era tendenciosa (de acordo com o teste de Egger). Depois de identificar e eliminar os grupos com TDE extremo, foi obtido um modelo corrigido e imparcial com 7 estudos e 9 TDE, no qual se constatou que o exercício aeróbico tem um efeito significativo, positivo e de grande magnitude sobre a aptidão cardiorrespiratória em sobreviventes da doença COVID-19 (TDE = 0,849; IC95%: 0,715 - 0,982; . = 7,13; . = 0,522; I. = 0,87%; Egger . = 0,205). As intervenções com exercícios aeróbicos melhoram o condicionamento cardiorrespiratório em sobreviventes da COVID-19. Dois estudos usaram apenas exercícios aeróbicos, enquanto os outros sete combinaram exercícios aeróbicos com exercícios de força e outras modalidades. Em todos os casos, houve um TDE significativo. Por fim, esses resultados foram relativamente homogêneos, sem evidências da influência de possíveis variáveis moderadoras.

ABSTRACT

Fundamento: la reanimación cardiopulmocerebral es el conjunto de maniobras para asegurar la oxigenación de los órganos cuando la circulación de la sangre se detiene. La reanimación cardiopulmocerebral intrahospitalaria es una intervención que salva vidas. Objetivo: caracterizar la atención médica durante la reanimación cardiopulmocerebral en pacientes que presentan parada cardiaca dentro del Hospital General Universitario Dr. Gustavo Aldereguía Lima de Cienfuegos. Método se realizó un estudio descriptivo, transversal en las cinco unidades de cuidados intensivos de la Vicedirección de Urgencias, entre enero hasta junio del 2020. Se estudiaron 152 pacientes que realizaron un paro cardiorespiratorio. Se estudiaron las variables relacionadas con el paciente, los síntomas y signos previos al PCR presentados por los pacientes así como signos vitales. Resultados la media de edad fue de 62,66 años, en el 54,6 % predominó el sexo masculino. La hipertensión arterial fue la comorbilidad más frecuente con un 60,5 %. El 32,9 % tuvo un tiempo de estadía previo al evento de más de 72 horas. En orden de frecuencia los signos o síntomas previos al evento de PCR con más presencia fueron: bradicardia (32,2 %); pulsos débiles (15,1 %); inconciencia (12,5 %) y cianosis con 10,5 %. El servicio de mayor de ocurrencia fue la Unidad de Cuidados Intensivos Clínica. La asistolia constituyó el ritmo eléctrico inicial más común (57,9 %). En el 100 % de los casos se realizó manejo avanzado de la vía aérea con tubo endotraqueal. La desfibrilación estuvo indicada en 42 pacientes donde el 15,1 % de estos recibió la primera desfibrilación en menos de 5 minutos. La causa de la suspensión de la reanimación en 95 de los pacientes estudiados fue el fallecimiento. Conclusiones: la atención médica ante el paro cardiorrespiratorio debe seguir perfeccionándose, a través de la superación del personal sanitario y el desarrollo de acciones organizativas hacia el proceso de reanimación cardiopulmocerebral intrahospitalaria.


Background: cardiopulmonary-cerebral resuscitation is the set of maneuvers to ensure oxygenation of organs when blood circulation stops. In-hospital cardiopulmonary-cerebral resuscitation is a life-saving intervention. Objective: to characterize medical care during cardiopulmonary-cerebral resuscitation in patients with cardiac arrest at the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos. Method: a descriptive, cross-sectional study was carried out in the five intensive care units of the Emergency Department, from January to June 2020. 152 patients who suffered cardiorespiratory arrest were studied. The variables related to the patient, the symptoms and signs presented by the patients prior to the PCR, as well as vital signs, were studied. Results: the average age was 62.66 years, in 54.6% the male sex predominated. Arterial hypertension was the most frequent comorbidity with 60.5%. 32.9% had a length of stay prior to the event of more than 72 hours. In order of frequency, the most prevalent signs or symptoms prior to the PCR event were: bradycardia (32.2%); weak pulses (15.1%); unconsciousness (12.5%) and cyanosis with 10.5%. The service with the highest occurrence was the Clinical Intensive Care Unit. Asystole was the most common initial electrical rhythm (57.9%). In 100% of the cases, advanced airway management was performed with an endotracheal tube. Defibrillation was indicated in 42 patients where 15.1% of these received the first defibrillation in less than 5 minutes. The cause of suspension of resuscitation in 95 of the patients studied was death. Conclusions: medical care in the face of cardiorespiratory arrest must continue to be improved, through the improvement of health personnel and the development of organizational actions towards the process of intrahospital cardiopulmonary-cerebral resuscitation.

ABSTRACT

RESUMO Objetivo Verificar a relação entre zumbido e aptidão cardiorrespiratória em pessoas após COVID-19. Métodos Estudo transversal com amostra de pessoas pós-COVID -19 que responderam à Escala Visual Analógica para zumbido e questionário padronizado contendo dados sobre internação e zumbido. Para avaliar a aptidão cardiorrespiratória, utilizou-se a avaliação clínica e o Teste de Bruce para mensurar o consumo de oxigênio diretamente (via analisador de gases, com utilização do consumo pico de oxigênio - VO2pico). Resultados Participaram 192 pessoas, com média de idade de 47,8 ± 12,6 anos. A prevalência de zumbido autorreferido foi de 27,1% (n = 52). Dos 52 pacientes com zumbido, 27 iniciaram com o sintoma durante ou após o diagnóstico de COVID-19. Houve diferença significativa para o VO2pico absoluto entre os grupos com e sem zumbido (p = 0,035), sendo que o grupo com zumbido apresentou os menores valores; o tamanho do efeito foi pequeno. Não houve correlação entre os escores da Escala Visual Analógica para o zumbido e os valores de VO2pico absoluto e relativo (p > 0,05). Conclusão Houve diferença estatisticamente significativa entre as queixas de zumbido e o VO2pico nas pessoas após a COVID -19, sendo que o grupo com zumbido apresentou o VO2pico absoluto menor do que o grupo sem zumbido. Nos pacientes com zumbido, também foi encontrado VO2pico absoluto e relativo menor para as mulheres, além do VO2pico relativo menor para os hipertensos e obesos.


ABSTRACT Purpose To verify the relation between tinnitus and cardiorespiratory fitness among people after COVID-19. Methods Cross-sectional study with a sample of people post Covid-19 who responded to the Visual-Analog Scale for tinnitus and standardized questionnaire containing data on hospitalization and tinnitus. To evaluate cardiorespiratory fitness, it used the clinical assessment and Bruce test to measure oxygen consumption directly (via gas analyzer, using peak oxygen consumption - VO2peak). Results In total, 192 participants were assessed, with a mean age of 47.8 ± 12.6 years . The prevalence of self-reported tinnitus was 27.1% (n = 52). Of these 52 patients with tinnitus, 27 people started with the symptom during or after the diagnosis of COVID-19. There was a significant difference for the absolute VO2peak and the groups with and without tinnitus (p = 0.035): the tinnitus group showed the lowest values, the effect size was small. There was no correlation between the scores of the Visual-Analog Scale for tinnitus and the absolute and relative VO2peak (p > 0.05). Conclusion There was a statistically significant difference between tinnitus complaints and the VO2peak among people post COVID-19, with the tinnitus group having a lower absolute VO2peak than the non-tinnitus group. In tinnitus patients, we also found lower absolute and relative VO2peak for women, in addition to lower relative VO2peak for hypertensive and obese patients.

ABSTRACT

Objective:To investigate the effect of low-resistance elastic band resistance training on elderly patients with pre-frailty.Methods:This was a prospective research. A total of 119 elderly patients with pre-frailty admitted to the Geriatric Hospital of Medical Health Group of First People′s Hospital of Xiangshan County from August 2020 to May 2021 were selected as the research objects by simple sampling method, and divided into the control group of 60 cases and the intervention group of 59 cases according to the time of admission, and the control group received routine nursing methods, the intervention group used low-resistance elastic bands for resistance training intervention on the basis of the control group. The intervention time was 12 weeks. Frail Asthenia Screening Scale, Motor Function Evaluation Scale for the Elderly and Pittsburgh Sleep Quality Index Scale were used to evaluate the asthenia, motor function and sleep quality of the two groups before and after the intervention, and statistical comparison was made.Results:There was no significant difference in the asthenia, motor function and sleep quality between the two groups before the intervention ( P>0.05). The asthenia score after the intervention in the intervention group was (0.83 ± 0.38) points, which was lower than that in the control group (1.05 ± 0.43) points, and the difference was statistically significant ( t=2.93, P<0.01). The total score of motor function, social activity, mobility difficulty, daily care and physical pain after the intervention in the intervention group were (49.36 ± 4.68), (21.85 ± 3.71), (10.31 ± 1.65), (9.93 ± 1.80), (7.27 ± 1.65) points, respectively, which were lower than those in the control group (53.67 ± 5.20), (23.45 ± 3.62), (11.10 ± 1.81), (11.00 ± 1.88), (8.12 ± 1.65) points, the differences were statistically significant ( t values were 2.38 - 4.75, all P<0.05). The total score of sleep quality and the scores of sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorder, hypnotic drug use and daytime functional disorder after the intervention in the intervention group were (6.54 ± 1.79), (1.02 ± 0.75) (0.95 ± 0.63), (0.95 ± 0.65), (0.80 ± 0.41), (1.29 ± 0.62), (0.53 ± 0.50), (1.02 ± 0.75) points, respectively, which were lower than those in the control group (8.92 ± 1.44), (1.38 ± 0.74), (1.40 ± 0.56), (1.37 ± 0.55), (0.93 ± 0.31), (1.58 ± 0.53), (0.72 ± 0.45), (1.53 ± 0.79) points, the differences were statistically significant ( t values were 2.06 - 7.97, all P<0.05). Conclusions:The implementation of low-resistance elastic band resistance training in elderly patients with pre-frailty can reduce the patient′s frail status, improve motor function and sleep quality, and has a certain clinical value.

ABSTRACT

Resumo Fundamento A intolerância ao exercício pós-COVID-19 não é bem entendida. O teste de esforço cardiopulmonar (TECP) pode identificar as limitações ao exercício subjacentes. Objetivos Avaliar a etiologia e a magnitude da intolerância ao exercício em sujeitos pós-COVID-19. Métodos Estudo de coorte que avaliou sujeitos com níveis de gravidades diferentes da doença COVID-19 e um grupo de controle selecionado por pareamento por escores de propensão. Em uma amostra seleta com TECP anterior à infecção viral disponível, foram realizadas comparações antes e depois. O nível de significância foi de 5% em toda a análise. Resultados Foram avaliados cento e quarenta e dois sujeitos com COVID-19 (idade mediana: 43 anos, 57% do sexo masculino), com níveis de gravidade de doença diferentes (60% leve, 21% moderada, 19% grave). O TECP foi realizado 11,5 (7,0, 21,2) semanas após o aparecimento da doença, com as limitações ao exercício sendo atribuídas aos sistemas muscular periférico (92%), pulmonar (6%), e cardiovascular (2%). Menor valor mediano do consumo de oxigênio pico percentual foi observado no subgrupo com níveis graves de doença (72,2%) em comparação com os controles (91,6%). O consumo de oxigênio foi diferente entre os grupos com diferentes níveis de gravidade de doença e o controle no pico e nos limiares ventilatórios. Inversamente, os equivalentes ventilatórios, a inclinação da eficiência do consumo de oxigênio, e o pico do pulso de oxigênio foram semelhantes. A análise do subgrupo de 42 sujeitos com TECP prévio revelou uma redução significativa no pico de velocidade da esteira no subgrupo com nível leve de doença, e no consumo de oxigênio no pico e nos limiares ventilatórios nos subgrupos com níveis moderado/grave. Por outro lado, os equivalentes ventilatórios, a inclinação da eficiência do consumo de oxigênio e o pico do pulso de oxigênio não apresentaram alterações significativas. Conclusões A fadiga do músculo periférico foi a etiologia de limitação de exercício mais comum em pacientes pós-COVID-19 independentemente da gravidade da doença. Os dados sugerem que o tratamento deve enfatizar programas de reabilitação abrangentes, incluindo componentes aeróbicos e de fortalecimento muscular.


Abstract Background Post-COVID-19 exercise intolerance is poorly understood. Cardiopulmonary exercise testing (CPET) can identify the underlying exercise limitations. Objectives To evaluate the source and magnitude of exercise intolerance in post-COVID-19 subjects. Methods Cohort study assessing subjects with different COVID-19 illness severities and a control group selected by propensity score matching. In a selected sample with CPET prior to viral infection, before and after comparisons were performed. Level of significance was 5% in the entire analysis. Results One hundred forty-four subjects with COVID-19 were assessed (median age: 43.0 years, 57% male), with different illness severities (60% mild, 21% moderate, 19% severe). CPET was performed 11.5 (7.0, 21.2) weeks after disease onset, with exercise limitations being attributed to the peripheral muscle (92%), and the pulmonary (6%), and cardiovascular (2%) systems. Lower median percent-predicted peak oxygen uptake was observed in the severe subgroup (72.2%) as compared to the controls (91.6%). Oxygen uptake differed among illness severities and controls at peak and ventilatory thresholds. Conversely, ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse were similar. Subgroup analysis of 42 subjects with prior CPET revealed significant reduction in only peak treadmill speed in the mild subgroup and in oxygen uptake at peak and ventilatory thresholds in the moderate/severe subgroup. By contrast, ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse did not change significantly. Conclusions Peripheral muscle fatigue was the most common exercise limitation etiology in post-COVID-19 patients regardless of the illness severity. Data suggest that treatment should emphasize comprehensive rehabilitation programs, including aerobic and muscle strengthening components.

ABSTRACT

ABSTRACT Introduction: The good performance of college students depends directly on their physical integrity, which is subordinated to good physical fitness and cardiopulmonary resistance. It is believed that aerobic training, an adaptation to the progressive increase of physical endurance, may benefit college students. Objective: Study whether aerobic training can affect college students' physical fitness and cardiopulmonary endurance. Methods: Through experimental comparison, the physical fitness and cardiopulmonary endurance of students in the aerobics elective class and the university athletics elective class were compared. Body indexes were measured before and after the intervention, statistically analyzed, and discussed according to the literature. Results: There were significant changes in the 50-meter run time for university students in the elective aerobics class from 9.24±1.71 to 7.81±2.02, the five-meter run from 11.56±1.03 to 7.87±0.23, the standing jump from 156.92±14.79 to 170.56±19.93, and the sitting flexion from 14.07±1.98 to 17.52±3.79. These changes accompanied the changes in cardiorespiratory endurance in the aerobics elective class. In contrast, the changes in student indicators in the track and field elective class were not as evident. Conclusion: Aerobic training positively impacted overall physical quality, including elevation of fitness indices and cardiopulmonary endurance in college students. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


RESUMO Introdução: O bom desempenho dos estudantes universitários depende diretamente de sua integridade física, que está subordinada a uma boa aptidão física e resistência cardiopulmonar. Acredita-se que o treinamento aeróbico, uma adaptação ao aumento progressivo da resistência física, possa trazer benefícios aos estudantes universitários. Objetivo: Estudar se a prática do treinamento aeróbico pode afetar a aptidão física e a resistência cardiopulmonar dos estudantes universitários. Métodos: Através de comparação experimental, a aptidão física e a resistência cardiopulmonar dos alunos da classe optativa de aeróbica e da classe optativa de atletismo universitário foram comparadas. Os índices corporais foram mensurados antes e após a intervenção, trabalhados estatisticamente e discutidos conforme a literatura. Resultados: Houveram alterações significativas no tempo de corrida 50 metros pelos estudantes universitários da classe eletiva de aeróbica, de 9,24±1,71 para 7,81±2,02, a de cinco metros foi de 11,56±1,03 para 7,87±0,23, o salto em pé foi de 156,92±14,79 para 170,56±19,93, e a flexão em posição sentada de 14,07±1,98 para 17,52±3,79. Essas alterações acompanharam as mudanças de resistência cardiorrespiratória na classe eletiva de aeróbica, enquanto as mudanças dos indicadores em alunos na classe eletiva de atletismo não foram tão evidentes. Conclusão: O treinamento em aeróbico mostrou um impacto positivo sobre a qualidade física geral, incluindo elevação dos índices de aptidão física e da resistência cardiopulmonar nos estudantes universitários. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT

Abstract This study aimed to compare the physical profile and motor profile of children from 6 to 10 years old, according to their level of cardiorespiratory fitness (CRF). Participated 2036 children from 6 to 10 years old from São José dos Pinhais - PR. Assessed variables were stature, corporal mass, Body mass index (BMI), physical fitness (PF), and gross motor coordination (GMC). The CRF was assessed by the total distance during the 6 minutes walking test. A battery of tests KTK evaluated the GCM. The children were classified according to their levels of CRF (low-moderate-elevated). Differences between groups were tested using ANOVA one way. Data analysis was made in the SPSS software, with a meaningfulness of 5%. Children with low levels of CRF showed higher values of adiposity. On the PF tests, children with low levels of CRF showed higher values of prehension and worse performance in the other tests. Regarding GMC, children with low levels of CRF had lower coordinative performance. Meaningful differences were found in the comparisons between different groups (low-moderate, low-elevated) with an advantage in the results in moderate levels of CRF. Obtaining average levels of CRF can bring protective benefits in other variables in children's growth process and development during infancy. Evaluating the CRF doesn't only get a momentary evaluation. Still, it can also do the monitoring of an essential variable of health, as well as indicate a predisposition about other physical-motor variables.


Resumo Comparar o perfil físico e motor de crianças dos 6 aos 10 anos, conforme os seus níveis de aptidão cardiorrespiratória (AptC). Participaram do estudo 2036 crianças de seis a 10 anos de idade de São José dos Pinhais-PR. Foram avaliados estatura, massa corporal, índice de massa corporal (IMC), aptidão física (AptF) e coordenação motora (CMG). A AptC foi avaliada pela distância total percorrida no teste de seis minutos. A CMG foi avaliada por meio da bateria de testes KTK. As crianças foram classificadas em função dos níveis de AptC (baixo-moderado-elevado). Diferenças entre grupos foram testadas utilizando da ANOVA one way. As análises dos dados foram realizadas no software SPSS, com nível de significância em 5%. Crianças com menor nível de AptC apresentam maiores valores médios adiposidade. Nos testes de AptF, crianças com níveis baixos de AptC apresentaram maiores valores de preensão e pior desempenho nos demais testes. Relativamente à CMG, crianças com baixos níveis de AptC apresentaram piores desempenho coordenativo. Diferenças significativas foram encontradas para as comparações entre os outros grupos (baixo-moderado; baixo-elevado) com vantagem nos resultados nos níveis moderados a elevados de AptC. Obter níveis moderados de AptC pode trazer benefícios protetores em diferentes variáveis do processo de crescimento e desenvolvimento de crianças durante a segunda infância. Avaliar a AptC não traz somente uma avaliação momentânea, como pode ser feito o monitoramento de uma importante variável de saúde bem como indicar uma predisposição sobre outras variáveis físico-motoras.

ABSTRACT

Background: From the past few decades, disturbed sleep pattern has grown to be a hallmark of modern-day society among the adolescents and in adults. Both are having disturbed sleep patterns with average sleep duration of 7 h per night. Smartphones, tablets, and television which are the remarkable source of information and entertainment have robbed sleep time and have led to voluntary sleep restriction as self-reported by them and it has become a serious barrier to health development. Along with-it, high blood pressure (BP) levels are influenced by high body mass index (BMI) and low cardiorespiratory fitness which are among the most important cardiovascular disease risk factors. However, how sleep attenuates the individuals BMI, cardiorespiratory fitness and BP in adolescents are uncertain. Aims and Objectives: The aim of this study was to analyze whether the disturbed sleep pattern is a mediator between body composition, Cardiorespiratory fitness (CRF), and BP levels in young adolescents. Materials and Methods: This study was a cross-sectional study which involved students of MMIMSR (n = 500), of which 250 male and 250 female participants were recruited. Initial explanation about the aim and purpose of the study, test procedure, method of testing, and instruction of how to perform the test was given. All the participants were examined under similar laboratory conditions. Detailed history with thorough clinical examination were done. All basal parameters such as heart rate, BP, and respiratory rate were also measured. Results: In our study, disturbed sleep patterns were highly significantly (P < 0.01) associated with high BMI which acted as a mediator between low CRF and high BP in both the participants. Our results highlighted the importance of a sleep in maintaining a healthy lifestyle, CRF and to prevent hypertension in young adolescents. Conclusion: The findings of our study are consistent with the hypothesis that disturbed sleep might be one of the reasons which influence BMI and long-term cardiovascular health.

ABSTRACT

Background: Obstructive sleep apnea (OSA) in pediatric population is associated with cardiac, respiratory, metabolic, neurocognitive, and behavioral dysfunctions. Adenotonsillectomy (AT) is the treatment of choice in children who have hypertrophied adenoid and/or palatine tonsils. However, there is paucity of literature on the impact of AT on cardiorespiratory and sleep parameters in these cases. Methods: We did a retrospective study on children who had undergone AT from July 2016 to December 2018 at a tertiary hospital in north India. Only those children, whose polysomnography (PSG) was available both before and after AT were enrolled in this study. � Cardiac parameters: Mean heart rate (MHR) and highest heart rate (HHR), number and duration of arrhythmias, and pulse transit time (PTT) drops. � Respiratory parameters: Apnea-hypopnea index (AHI), respiratory disturbance index (RDI), oxygen desaturation index (ODI), mean oxygen saturation (MOS). � Sleep parameters: Time spent in different stages, sleep efficiency (SE), and arousal index (AI) on PSG were compared before and after AT. Results: A total of 56 children had undergone AT for OSA. Also, PSG, both before and after AT, was available in 37 children. After excluding children having undergone other surgeries for OSA and those with comorbidities, 32 children were enrolled. AT led to significant positive change in AHI (from 7.86 � 7.91 to 2.03 � 3.10, p = 0.01), RDI (from 16.319 � 15.64 to 7.38 � 3.72, p < 0.01), AI (from 22.10 � 14.93 to 15.90 � 8.48, p = 0.012), SE (from 91.47 � 6.31 to 95.866 � 3.03, p < 0.01), ODI (from 6.7959 � 5.03 to 1.865 � 2.09, p < 0.01), MOS (from 95.59 � 2.19 to 97.28 � 1.27), HHR (from 141.68 � 17.93 to 120.93 � 16.98, p < 0.01), MHR (86.68 � 12.95 to 80.29 � 8.81, p = 0.01), and PTT AI (from 36.67 � 27.72 to 26.93 � 24.86, p < 0.01). There was no non-sinus wide or narrow complex tachyarrhythmia in any child before or after AT. There was no statistically significant change in rapid eye movement (REM) sleep duration or number and duration of bradycardia episodes in these children (p > 0.05). Conclusion: Adenotonsillectomy improved SE and oxygenation, and decreased the number of obstructive events, arousals, heart rate, and PTT AI during sleep in children with OSA. Some children had residual disease after surgery. Heart rate and PTT can be excellent non-invasive parameters for detecting obstructive events during sleep in children and monitoring the impact of various therapeutic modalities.

Introduction: Cardiorespiratory fitness is a predictor of cardiovascular and all-cause mortality. Its assessment in different groups has clinical and public health usefulness. Objective: To evaluate the validity and reproducibility of a no-exercise method [National Aeronautics and Space Administration (NASA) method] to estimate the maximum oxygen consumption (VO2máx) in college adults. Materials and methods: This study included 94 healthy individuals of both sexes (1855 years). The gold standard was ergospirometry. The validity and reproducibility were evaluated with the intraclass correlation coefficient (ICC) and the Bland-Altman method. Results: Among the participants, we found a mean age of 30.54 ± 9.33 years and a VO2máx of 41.29 ± 9.54 ml O2kg-1-min-1; 48.9 % were women. A mean difference of VO2máx between ergospirometry and that estimated by the NASA method of 3.41 ± 5.64 ml O2.kg-1. min-1 was found. The concordance between the two methods was good, with an ICC of 0.858 (CI95% 0.672-0.926). The percentage of error was 29.70 %. The reproducibility of the two estimates by the NASA method was excellent, with an ICC of 0.986 (CI95% 0.927-0.995). Conclusions: The NASA method is valid and reproducible to estimate VO2máx in college adults. In addition, it is safe and easy to apply. Estimating cardiorespiratory fitness is recommended to improve screening in cardiometabolic risk programs and to implement timely interventions.

ABSTRACT

The purpose of the study was to find out the effect of selected yogic practices on vital capacity among college students. To achieve this purpose of the study, forty male students were selected as subjects who were from the various Department of Ewing Christian College, Prayagraj. The selected subjects were aged between 17 to 19 years. They were divided into two equal groups of twenty each, Group I underwent yogic exercise practice and group II acted as control that did not participate in any special training apart from their regular sports and games practices. The subjects were tested on selected criterion variables such as vo2 max prior to any immediately after the training period. The selected criterion variable such as vo2 max was measuring by queen's college step test. The analysis of covariance (ANCOVA) was used to find out the significant differences if any, between the experimental group and control group on selected criterion variable. The 0.05 level of confidence was fixed to test the significance, which was considered as an appropriate. The result of the present study has revealed that there was a significant difference among the experimental and control group on vo2 max.

ABSTRACT

ABSTRACT Introduction: Obesity is a major cause of chronic diseases such as cardiovascular and cerebrovascular diseases, cancer, and diabetes. Recent studies have reported that combined aerobic and anaerobic exercise effects are more effective for fat reduction. However, aerobic and anaerobic exercise have different fat reduction mechanisms. Comparing the intervention effects of different combinations of these exercises could provide an experimental basis for establishing an optimal protocol for weight loss. Objective: To study the effect of different aerobic exercise intensities on cardiorespiratory endurance in obese patients and its impact on fat loss. Methods: 18 obese female college students (BMI≥25) were randomly divided into two groups with different proportions of aerobic and anaerobic exercise. Bioimpedance data and BMI were collected for analysis. SPSS 25.0 software was used for statistics, with mean and standard deviation expressed for each index. Significance level at p<0.05 and highly significant set at P<0.01. Results: The weight, BMI, waist-to-hip ratio, and body fat content of the two exercise methods were positively changed before and after the experiment. This change had a very significant difference. Conclusion: There was no statistical difference in the interventions for the six weeks. Aerobic exercise can effectively improve cardiopulmonary function, and the benefits are directly proportional to the period practiced. Evidence Level II; Therapeutic Studies - Investigating the results.


RESUMO Introdução: A obesidade é uma causa importante de doenças crônicas como doenças cardiovasculares e cerebrovasculares, câncer e diabetes. Estudos recentes relataram que os efeitos do exercício aeróbico e anaeróbico combinados são mais eficazes para a redução de gordura. O exercício aeróbico e o exercício anaeróbico têm diferentes mecanismos de redução de gordura e a comparação dos efeitos da intervenção de diferentes combinações desses exercícios poderia fornecer uma base experimental para o estabelecimento de um protocolo ideal para perda de peso. Objetivo: Estudar o efeito de diferentes intensidades de exercícios aeróbicos sobre a resistência cardiorrespiratória de pacientes obesos e seu impacto sobre a perda de gordura. Métodos: 18 estudantes universitárias obesas (IMC≥25) foram divididas aleatoriamente em dois grupos com proporções distintas de exercícios aeróbicos e anaeróbicos. Assim como o IMC, dados coletados via bioimpedância foram mensurados antes e depois do experimento para análise. Foi utilizado o Software SPSS 25.0 para a estatística, com média e desvio padrão expressos para cada índice. Nível de significância em p<0,05 e muito significativo fixado em P<0,01. Resultados: O peso, IMC, relação cintura/quadril, e conteúdo de gordura corporal dos dois métodos de exercício foram positivamente alterados antes e depois do experimento. Essa alteração teve uma diferença muito significativa. Conclusão: Não houve diferença estatística nas intervenções pelo período de seis semanas. O exercício aeróbico pode efetivamente melhorar a função cardiopulmonar e os benefícios são diretamente proporcionais ao período praticado. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

ABSTRACT

ABSTRACT Introduction: Research on the effects of exercise on the cardiovascular system has a long history that has recently been expanded with echocardiography. Research using Doppler echocardiography has been increasing because of the safe and non-invasive method of examination to study cardiac morphology and function. However, few studies on functional cardiac changes in mid and long-distance runners under training are still few. Objective: Study the monitoring of cardiovascular response in middle and long-distance runners during training. Methods: The CFOCS-I cardiovascular function detector was used to observe 24 indices of cardiac pump function, vascular function, and microcirculation in 12 female middle-distance runners. Results: According to the test results, diastolic force, systolic force, systolic function, left ventricular ejection fraction increased during the proposed loading exercise. The mean systolic and mean pulse pressures increased significantly with exercise load (P<0.01). Conclusion: Mid and long-distance runners demonstrated significant cardiac changes in ventricular shape, size, and systolic function, accompanied by significant changes in diastolic function when subjected to intense exercise. Evidence Level II; Therapeutic Studies - Investigating the result.
