Association between the practice of fitness-related exercises and body image dissatisfaction in adolescents from Curitiba (PR), Brazil / Associação entre a prática de exercícios físicos relacionados ao fitness e insatisfação com a imagem corporal em adolescentes de Curitiba (PR), Brasil

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10-16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as "does not practice," "practices ≤300 min/week," and "practices >300 min/week" by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08-1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35-0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em "não pratica", "pratica ≤300 minutos/semana" e "pratica >300 minutos/semana". As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08-1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35-0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

Association of breastfeeding related musculoskeletal pain, sleep quality and physical activity among postpartum women: a literature review

Women often report musculoskeletal ailments during perinatal period resulting in less sleep hours and decline in physical activity. It has been speculated that physical activity can lower the frequency of muscular pain and enhance good quality sleep among women. Hence, the review aimed to investigate the association of breastfeeding related musculoskeletal pain, sleep quality and physical activity thus refining quality of life among women. Literature search was performed using search strategy on PubMed, Scopus and Pedro databases during 2019-2023. A total 54,037 articles were found via database searching out of which only 16 studies were relevant meeting the inclusion criteria. All the studies found that breastfeeding related musculoskeletal pain, sleep quality and physical activity are associated with each other. To lower the incidence of muscular pain and improve sleep quality, physical activity can be incorporated thus preventing occurrence of future complications. Hence, it has been suggested that physical activity is key solution of emerging musculoskeletal pain and broken sleep quality. Evidence from this literature supports that prenatal education emphasizing necessity of physical activity should be routinely integrated into maternal care in an effort to reduce chances of future complications.

Effects of hypopressive exercise associated with aerobic and muscle strength training on the treatment of fatigue, urinary incontinence symptoms, sexual function, and quality of life in women treated for gynecologic cancer: A randomized clinical trial protocol / Efectos del ejercicio hipopresivo asociado con el entrenamiento aeróbico y de fuerza muscular en el tratamiento de la fatiga, los síntomas de la incontinencia urinaria, la función sexual y la calidad de vida en mujeres tratadas por cáncer ginecológico: un protocolo de ensayo clínico aleatorizado

Introduction Therapeutic exercise has an important role in the population living with cancer as it improves function and quality of life and reduces the symptoms of cancer treatment. There is little clinical evidence on the effects of hypopressive exercise in women with gynecological cancer. Objective Evaluate the effects of 4 weeks of hypopressive exercise associated with muscle strength training and aerobic exercises on fatigue, urinary incontinence symptoms, sexual function, and quality of life in women treated for gynecological cancer compared to a group that will perform conventional training. Methods This randomized, single-blinded clinical trial study is set in the Clinical Research Laboratory, Department of Kinesiotherapy, at a Chilean University. Patients will be randomly assigned to an experimental group of hypopressive exercises associated with muscle strength training and aerobic exercises or a control group of muscle strength training and aerobic exercises. Twelve tele-rehabilitation sessions will be performed. Women over 18 years of age with gynecologic cancer who have been prescribed radiotherapy or chemotherapy will participate. Fatigue, quality of life, urinary incontinence symptoms, and sexual function will be assessed before and after the intervention. Expected results The results of this clinical trial have important implications for specific treatment for the cancer population and generate new techniques in the practice of oncology-specialized kinesiologists. Hypopressive exercise is expected to reduce incontinence symptoms due to neuromuscular activation of the pelvic floor muscles. However, more studies are needed to confirm the beneficial effects of hypopressive exercises in face-to-face or remote rehabilitation.

Introducción El ejercicio terapéutico juega un rol importante en la población con cáncer, ya que mejora la función, la calidad de vida y reduce los síntomas del tratamiento contra el cáncer. Hay poca evidencia clínica sobre los efectos del ejercicio hipopresivo en mujeres con cáncer ginecológico. Objetivo Evaluar los efectos de cuatro semanas de ejercicio hipopresivo asociado con entrenamiento de fuerza muscular y ejercicios aeróbicos sobre la fatiga, los síntomas de incontinencia urinaria, la función sexual y la calidad de vida en mujeres tratadas por cáncer ginecológico, en comparación con un grupo que realizará entrenamiento convencional. Métodos El escenario para este estudio de ensayo clínico aleatorizado y simple ciego es el Laboratorio de Investigación Clínica, Departamento de Kinesiología, en una Universidad Chilena. Las pacientes serán asignadas aleatoriamente a un grupo experimental de ejercicios hipopresivos asociados con entrenamiento de fuerza muscular y ejercicios aeróbicos, o a un grupo de control de entrenamiento de fuerza muscular y ejercicios aeróbicos. Se realizarán doce sesiones de telerehabilitación. Participarán mujeres mayores de 18 años con cáncer ginecológico a quienes se les haya indicado radioterapia o quimioterapia. Se evaluarán la fatiga, la calidad de vida, los síntomas de incontinencia urinaria y la función sexual antes y después de la intervención. Resultados esperados Los resultados de este ensayo clínico tienen importantes implicaciones en términos del tratamiento específico para la población con cáncer y generan nuevas técnicas en la práctica de kinesiólogos especializados en oncología. Se espera que el ejercicio hipopresivo reduzca los síntomas de incontinencia debido a la activación neuromuscular de los músculos del suelo pélvico. Sin embargo, se necesitan más estudios para confirmar los efectos beneficiosos de los ejercicios hipopresivos, ya sea en rehabilitación presencial o a distancia.

Treinamento Físico Reduz a Inflamação e a Fibrose e Preserva a Função e a Perfusão Miocárdica em um Modelo de Cardiomiopatia Chagásica Crônica / Exercise Training Reduces Inflammation and Fibrosis and Preserves Myocardial Function and Perfusion in a Model of Chronic Chagas Cardiomyopathy

Resumo Fundamento: A Cardiomiopatia Chagásica Crônica (CCC) é causada por um processo inflamatório induzido pelo Trypanosoma cruzi, que leva à miocardite com fibrose reativa e reparativa. A CCC progride com alterações de perfusão miocárdica e eventos histopatológicos que afetam a Aptidão Cardiorrespiratória (ACR). Objetivos: Avaliamos os efeitos do Treinamento Físico Aeróbico (TFA) na perfusão miocárdica e nos comprometimentos morfológicos e funcionais relacionados à inflamação e fibrose em hamsters sírios com CCC. Como objetivo secundário, analisamos as áreas de secção transversa do músculo esquelético. Métodos: Hamsters com CCC e seus respectivos controles foram divididos em quatro grupos: CCC sedentário, CCC-TFA, controle sedentário e controle TFA. Sete meses após a infecção, os animais foram submetidos à ecocardiografia, à cintilografia de perfusão miocárdica e ao teste de esforço cardiopulmonar. TFA de intensidade moderada foi realizado durante cinquenta minutos, cinco vezes por semana, por oito semanas. Posteriormente, os animais foram reavaliados. A análise histopatológica foi realizada após os procedimentos acima mencionados. O nível de significância foi estabelecido em 5% em todas as análises (p<0,05). Resultados: Animais com CCC sedentários apresentaram piores Defeitos de Perfusão Miocárdica (DPM) ao longo do tempo, Fração de Ejeção do Ventrículo Esquerdo (FEVE) reduzida, e apresentaram mais inflamação e fibrose quando comparados aos demais grupos (análise ANOVA mista). Por outro lado, o TFA foi capaz de mitigar a progressão do DPM, atenuar a inflamação e a fibrose e melhorar a eficiência da ACR em animais CCC-TFA. Conclusão: Nosso estudo demonstrou que o TFA melhorou a disfunção cardíaca, DPM e reduziu a inflamação e a fibrose em modelos de hamster com CCC. Além disso, os animais CCC-SED apresentaram atrofia do músculo esquelético, enquanto os animais CCC-TFA apresentaram a AST do músculo esquelético preservada. Compreender os efeitos da TFA nas dimensões fisiopatológicas da CCC é crucial para futuras pesquisas e intervenções terapêuticas.

Abstract Background: Chronic Chagas cardiomyopathy (CCC) is caused by an inflammatory process induced by Trypanosoma cruzi, which leads to myocarditis with reactive and reparative fibrosis. CCC progresses with myocardial perfusion abnormalities and histopathological events that affect cardiorespiratory fitness (CRF). Objectives: We evaluated the effects of aerobic physical training (APT) on myocardial perfusion and on morphological and functional impairments related with inflammation and fibrosis in Syrian hamsters with CCC. As a secondary objective, we analyzed the cross-sectional areas of the skeletal muscle. Methods: Hamsters with CCC and their respective controls were divided into four groups: CCC sedentary, CCC-APT, sedentary control and APT control. Seven months after infection, the animals underwent echocardiography, myocardial perfusion scintigraphy and cardiopulmonary exercise testing. Moderate-intensity APT was performed for fifty minutes, five times a week, for eight weeks. Subsequently, the animals were reassessed. Histopathological analysis was conducted after the above-mentioned procedures. The level of significance was set at 5% in all analyses (p<0.05). Results: CCC sedentary animals presented worse myocardial perfusion defects (MPD) over time, reduced left ventricle ejection fraction (LVEF) and showed more inflammation and fibrosis when compared to other groups (mixed ANOVA analysis). Conversely, APT was able to mitigate the progression of MPD, ameliorate inflammation and fibrosis and improve CRF efficiency in CCC-APT animals. Conclusions: Our study demonstrated that APT ameliorated cardiac dysfunction, MPD, and reduced inflammation and fibrosis in CCC hamster models. Additionally, CCC-SED animals presented skeletal muscle atrophy while CCC-APT animals showed preserved skeletal muscle CSA. Understanding APT's effects on CCC's pathophysiological dimensions is crucial for future research and therapeutic interventions.

Investigating Morphological Changes of the Hippocampus After Prolonged Aerobic Exercise in Mice: Neural Function and Learning Capabilities / Investigación de los Cambios Morfológicos del Hipocampo Después De un Ejercicio Aeróbico Prolongado en Ratones: Función Neuronal y Capacidades de Aprendizaje

SUMMARY: Both the academic and popular worlds have paid close attention to the link between exercise and cognitive performance. It is increasingly important to understand the numerous mechanisms by which exercise might influence cognitive abilities in view of the continuous societal issues caused by aging populations and the prevalence of disorders associated to cognitive decline. A rising amount of evidence showing a favorable association between physical activity and cognitive well-being serves as the foundation for the justification for studying the effects of exercise on cognitive function and learning ability. The study employed an 8-week treadmill based on exercise on male adults C57BL/6 mice. The exercise group were engaged in 5 sessions a week gradually increasing the intensity of the protocol by 5 % each week. The Mice cognitive assessments were done using Morris Water Maze and Novel Object Recognition tests. The long term-impact on learning ability were further assessed through immmohistochemistry and molecular analysis of the hippocampal and prefrontal cortex tissues of the animals' brain tissues. The findings showed improved spatial learning abilities, recognition memory, and heighted synaptic plasticity indicated by elevated synaptic makers. The study underscores the role of long-term aerobic exercise in augmenting cognitive performance. It not only contributes to the understanding of the interplay between neuroplasticity and cognitive benefits but also the growing body of research on the impact of exercise on cognitive function.

Tanto el mundo académico como el popular han prestado mucha atención al vínculo entre el ejercicio y el rendimiento cognitivo. Es cada vez más importante comprender los numerosos mecanismos por los cuales el ejercicio podría influir en las capacidades cognitivas en vista de los continuos problemas sociales causados por el envejecimiento de la población y la prevalencia de trastornos asociados al deterioro cognitivo. Una cantidad cada vez mayor de evidencia que muestra una asociación favorable entre la actividad física y el bienestar cognitivo sirve como base para justificar el estudio de los efectos del ejercicio sobre la función cognitiva y la capacidad de aprendizaje. El estudio se realizó en ratones machos adultos C57BL/6 utilizándose en los ejercicios una cinta rodante durante 8 semanas. El grupo de ejercicio realizó 5 sesiones por semana aumentando gradualmente la intensidad del protocolo en un 5 % cada semana. Las evaluaciones cognitivas de los ratones se realizaron utilizando las pruebas Morris Water Maze y Novel Object Recognition. El impacto a largo plazo en la capacidad de aprendizaje se evaluó mediante inmunohistoquímica y análisis molecular de los tejidos del hipocampo y la corteza prefrontal de los tejidos cerebrales de los animales. Los hallazgos mostraron mejoras en las habilidades de aprendizaje espacial, la memoria de reconocimiento y una mayor plasticidad sináptica indicada por unos creadores sinápticos elevados. El estudio subraya el papel del ejercicio aeróbico a largo plazo para aumentar el rendimiento cognitivo. No sólo contribuye a la comprensión de la interacción entre la neuroplasticidad y los beneficios cognitivos, sino también al creciente conjunto de investigaciones sobre el impacto del ejercicio en la función cognitiva.

Methodology: A literature search was performed in the electronic databases Pubmed, Scopus and Web of Science, using the following keywords: 'cluster training', 'rest interval', 'rest pause', 'hypertrophy', 'resistance training' and 'cross sectional area'. We included clinical trials that used cluster training as an intervention in people over 18 years of age of both sexes. Results: The systematic review obtained during the search of the databases consulted yielded a total of 23 potentially eligible articles, of which a sample of 9 was taken from which results could be obtained that responded to the objective of this review. The number of participants from the 9 eligible articles was 172 subjects. Cluster workouts allow for increased training volume and intensity without causing high levels of fatigue, thus favoring the development of muscle hypertrophy. Conclusions: The results of this systematic review suggest that cluster training can be an effective tool for the development of muscle hypertrophy.

Influência da prática de atividade física no desempenho cognitivo de adultos de meia-idade e pessoas idosas: um estudo longitudinal realizado antes e durante a pandemia / Influence of physical activity on the cognitive performance of middle-aged ans older adults: a longitudinal study carried out before and during the pandemic

Objetivo: Analisar a influência da prática de atividade física no desempenho cognitivo de adultos de meia-idade e pessoas idosas antes e durante a pandemia. Métodos: Estudo longitudinal e quantitativo, realizado com 200 indivíduos com 45 anos ou mais de idade cadastrados em Unidades de Saúde da Família de Três Lagoas/MS. A coleta aconteceu em dois momentos, antes da pandemia (2018/19) e durante a pandemia (2021). Foram avaliados dados sociodemográficos, a prática de atividade física (Questionário Internacional de Atividade Física - IPAQ) e o desempenho cognitivo (Mini-Exame do Estado Mental ­ MEEM). Os dados foram analisados pelos testes de McNemar, qui-quadrado, teste T e teste de Wilcoxon para amostras pareadas. Resultados: Com relação à prática de atividades físicas, 28% da amostra se tornou inativa no período avaliado, e 12% se tornou ativa, com diferença significativa. Não houve diferença entre os participantes que se tornaram ativos, se tornaram inativos, se mantiveram ativos e se mantiveram inativos com relação às características sociodemográficas, indicando que os grupos são semelhantes. O desempenho cognitivo piorou significativamente na comparação entre as duas avaliações. Ao analisar os grupos separadamente, verificou-se que o grupo que se tornou inativo foi o único que teve um desempenho cognitivo significativamente pior, na comparação antes e durante a pandemia. Conclusão: A redução da prática de atividade física decorrente da pandemia em adultos de meia-idade e pessoas idosas influenciou negativamente no desempenho cognitivo. Os indivíduos que deixam de praticar atividades físicas devem ser o principal alvo de rastreamento e monitoramento cognitivo, especialmente em períodos pandêmicos.

Objective: To analyze the influence of physical activity on the cognitive performance of middle-aged and older adults before and during the pandemic. Methods: Longitudinal and quantitative study, carried out with 200 individuals aged 45 years or older enrolled in Family Health Units in Três Lagoas/MS. The data collection took place in two moments, before the pandemic (2018/19) and during the pandemic (2021). Socio-demographic data, physical activity practice (International Physical Activity Questionnaire - IPAQ) and cognitive performance (Mini-Mental State Examination - MMSE) were evaluated. Data were analyzed using McNemar, chi-square, t-test and Wilcoxon test for paired samples. Results: Regarding the practice of physical activities, 28% of the sample became inactive during the period evaluated, and 12% became active, with a significant difference. There was no difference between participants who became active, became inactive, remained active and remained inactive with regard to sociodemographic characteristics, indicating that the groups are similar. Cognitive performance significantly worsened when comparing the two assessments. When analyzing the groups separately, it was found that the group that became inactive was the only one that had a significantly worse cognitive performance, in the comparison before and during the pandemic. Conclusion: The reduction in the practice of physical activity due to the pandemic in middle-aged and older adults negatively influenced cognitive performance. Individuals who stop practicing physical activities should be the main target for tracking and cognitive monitoring, especially in pandemic periods.

Modelo preditivo do número de passos semanais, mediante a fragilidade física de centenários: Projeto SC100 / Predictive model for the number of weekly steps, based on the physical fragility of centenarians: Project SC100

Objetivo: Propor modelo preditivo do número de passos semanais, mediante aos critérios do fenótipo de fragilidade de centenários, fatores sociodemográficos, condições de saúde e hábitos de vida. Método: Trata-se de uma pesquisa transversal que faz parte do 'Projeto SC100: Estudo Multidimensional dos Centenários de Santa Catarina'. Os critérios do fenótipo de fragilidade foram: perda da massa corporal não intencional, fadiga, fraqueza muscular, redução da velocidade da marcha e o baixo nível de atividade física. O número de passos/dia em uma semana normal foi medido por meio do pedômetro durante 7 dias de uma semana normal. Os dados foram coletados por pesquisadores previamente treinados nas residências dos idosos. A regressão logística binária foi empregada para construir os modelos preditivos. Resultados: Foram avaliados 54 centenários com média de idade de 101,8±2,8 anos. Os centenários que apresentam menos passos por semana tem 4,61 (IC95%: 1,34-15,94) vezes maior chance de apresentar o critério baixa velocidade da marcha, este resultado foi ajustado pelas variáveis sociodemográficas. Centenários que apresentam menos passos por semana tem 8,29 (IC95%: 2,05-33,37) vezes maior chance de apresentar o critério baixa velocidade da marcha e 3,35 (IC95%: 1,02-11,38) vezes maior chance de apresentar o critério fadiga, estes resultados foram ajustados por variáveis de hábitos de vida. Conclusão: Centenários com menor número de passos/semana apresentam algum dos critérios do fenótipo de fragilidade (perda da massa corporal não intencional, fadiga, fraqueza muscular e redução da velocidade da marcha), independente das variáveis sociodemográficas (sexo, escolaridade, estado civil e renda) e hábitos de vida (histórico de tabagismo, etilismo e comportamento sedentário).

Objective: To propose a predictive model of the number of weekly steps, according to the criteria of the frailty phenotype of centenarians, the sociodemographic factors, health conditions and life habits. Method: This is a cross-sectional research that is part of the "Projeto SC100: Estudo Multidimensional dos Centenários de Santa Catarina". The frailty phenotype criteria were: unintentional body mass loss, fatigue, muscle weakness, reduced walking speed, and low level of physical activity. The number of steps/day in a normal week was measured using a pedometer during 7 days of a normal week. Data were collected by previously trained researchers in the homes of the older adults. Binary logistic regression was employed to build the predictive models. Results: We evaluated 54 centenarians with a mean age of 101.8±2.8 years. Among the main results, centenarians who have fewer steps per week are 4.61 (95% CI: 1.34-15.94) times more likely to have the criterion low walking speed, this result was adjusted by socio-demographic variables. Also, centenarians who have fewer steps per week have 8.29 (95%CI: 2.05-33.37) times more chance of presenting the criterion low walking speed and 3.35 (95%CI: 1.02-11.38) times more chance of presenting the criterion fatigue, these results were adjusted by lifestyle variables. Conclusion: Centenarians with fewer steps per week present any of the frailty phenotype criteria (loss of unintentional body mass, fatigue, muscle weakness and reduced gait speed), regardless of socio-demographic variables (gender, education, marital status and income) and lifestyle habits (smoking history, alcoholism and sedentary behavior).

Efectividad de un programa de rehabilitación cardiopulmonar en trabajadores de la salud con infección por COVID-19 / Changes in functional and cardiopulmonary outcomes in patients with COVID-19 infection after a cardiopulmonary rehabilitation program

Resumen Objetivo: evaluar, en una población trabajadora de la salud con COVID-19, la gravedad de la enfermedad y el impacto de un programa de rehabilitación cardiopulmonar ambulatorio fase II basado en ejercicio, en la capacidad funcional, la función medida con la Escala de Estado Funcional posCOVID y el reintegro laboral. Materiales y método: se realizó un estudio cuasiexperimental en 48 trabajadores de la salud con infección por COVID-19. Al inicio y al final se les evaluó gravedad de la infección, función cardiopulmonar y escala de estado funcional post-COVID-19 (PCFS). Se hizo un programa de rehabilitación cardiopulmonar con tres sesiones semanales de ejercicio continuo e interválico individualizado, con una duración de 20 a 60 minutos y una intensidad del 60 al 80% de la frecuencia cardíaca máxima durante un mes. Resultados: hubo 19 casos moderados y 29 graves. La edad promedio fue 54 (DE: 15.5) años, 41.7% eran empleados, 47.9% obesos y 39.6% hipertensos. El 68.8% tuvo neumonía típica, el 29.2% estrés postraumático, el 43.8% síndrome depresivo y el 50% trastornos de ansiedad. La capacidad cardiopulmonar pasó de NYHA II (5.7 DE: 1.2) a NYHA I (8.2: DE: 2.0). Mejoró la independencia en actividades de la vida diaria (ADV) (escala PCFS) y 36 pacientes regresaron a su trabajo. No hubo complicaciones graves. Conclusión: este estudio demostró el impacto positivo de un programa de rehabilitación cardiopulmonar en la función cardiopulmonar y la independencia en actividades diarias e instrumentales en trabajadores de la salud con COVID-19, pues un 75% de estos regresó a sus labores habituales.

Abstract Objective: to evaluate, in a health worker population with COVID-19, the severity of the disease and the impact of an outpatient phase II PRCP based on exercise, on functional capacity, function measured with the post-COVID Functional Status Scale and job reinstatement. Materials and method: a quasi-experimental study was conducted involving 48 healthcare workers with COVID-19. Severity of infection, cardiopulmonary function, and PCFS were assessed at the beginning and end. The CPRP included a program of three weekly sessions of individualized continuous and interval exercises lasting 20 to 60 minutes, with an intensity of 60 to 80% of maximum heart rate over one month. Results: there were 19 moderate cases and 29 severe cases. The average age was 54 (SD: 15.5) years, with 41.7% being employees, 47.9% obese, and 39.6% hypertensive, 68.8% had typical pneumonia, 29.2% experienced post-traumatic stress, 43.8% had depressive syndrome, and 50% had anxiety disorders. Cardiopulmonary capacity improved from NYHA II (5.7 SD: 1.2) to NYHA I (8.2 SD: 2.0). Independence in activities of daily living (PCFS scale) improved and 36 patients returned to work. There were no severe complications. Conclusion: This study demonstrated a positive impact of the CPRP on cardiopulmonary function and independence in daily and instrumental activities among healthcare workers with COVID-19, with 75% returning to their regular duties.

Mastectomía y ejercicio físico

Se han evidenciado beneficios importantes cuando se realiza actividad física de intensidad moderada luego del diagnóstico de cáncer de mama. Las intervenciones deben comenzar antes, durante y después de la intervención quirúrgica. Se recomienda tener en cuenta: el estadio de la enfermedad, el tipo de cáncer, la condición física, la posibilidad de reducir el volumen o la intensidad de ejercicio; de no ser así se deberá empezar de forma progresiva aumentando poco a poco la intensidad y la duración de la actividad física. La actividad física ejercida de forma regular y con cierta intensidad reduce el riesgo de recidiva tumoral y la mortalidad por cáncer de mama; aumenta la calidad de vida, disminuye los efectos tóxicos de los tratamientos, por lo tanto, mejora el pronóstico de la enfermedad.

Important benefits have been shown when performing moderate-intensity physical activity after the diagnosis of breast cancer. Interventions must begin before, during and after the surgical intervention. It is recommended to take into account: the stage of the disease, the type of cancer, the physical condition, the possibility of reducing the volume or intensity of exercise; if not, you should start progressively, gradually increasing the intensity and duration of physical activity. Physical activity exercised regularly and with a certain intensity reduces the risk of tumor recurrence and mortality from breast cancer; it increases the quality of life, reduces the toxic effects of treatments, therefore, improves the prognosis of the disease.
