Factors Associated with Cardiorespiratory Fitness in Breast Cancer Survivors from the State of Santa Catarina, Brazil: Cross-Sectional Study

Introduction: Oxygen consumption (VO2 ) is indicative of cardiorespiratory fitness (CRF) and lower levels are related to a higher risk of total mortality among individuals with cancer whose therapy can have adverse consequences on the cardiovascular system. Objective: To examine the associations of patient-reported sociodemographic, clinical, anthropometric outcomes and functional variables with CRF in 69 women (55±10 years) and to identify whether walking is a predictor of peak VO2 variation in this population with breast cancer (BC). Method: Female BC survivors receiving hormone therapy after two types of surgery (breast-conserving and mastectomy) underwent a CRF test on a cycle ergometer to measure peak VO2 . A questionnaire containing sociodemographic, clinical data, patient reported outcomes (PROs) (depressive symptoms, sleep quality, fatigue, body image) and self-reported walking and tests to measure body fat percentage, waist circumference, flexibility and shoulder range of motion (RoM) were performed. Results: Unemployment and retirement were associated with low CRF, as was the use of aromatase inhibitors instead of tamoxifen. Depressive symptoms, worse body image, greater waist circumference, less flexibility and shoulder RoM were also associated with low CRF. Walking duration, controlled for age and body mass index (BMI), is a 13% predictor of peak VO2 variance in this sample. Conclusion: These factors must be considered in understanding the CRF profile of BC survivors. As walking was a predictor of peak VO2 variance, it should be recommended as a type of physical activity for patients with BC using hormone therapy.

Introdução: O consumo de oxigênio (VO2 ) é indicativo de aptidão cardiorrespiratória (ACR), e níveis mais baixos estão relacionados a um maior risco de mortalidade total entre indivíduos com câncer cuja terapia pode ter consequências adversas no sistema cardiovascular. Objetivo: Examinar as associações de desfechos sociodemográficos, clínicos, antropométricos relatados pelo paciente e variáveis funcionais com a ACR de 69 mulheres (55±10 anos), e identificar se a caminhada é um preditor de variação do pico de VO2 nessa população com câncer de mama (CM). Método: Mulheres sobreviventes de CM recebendo terapia hormonal após dois tipos de cirurgias (conservadora e mastectomia) realizaram um teste de ACR em cicloergômetro para medir o VO2 pico. Um questionário contendo dados sociodemográficos e clínicos; resultados relatados pelos pacientes (RRP) (sintomas depressivos, qualidade do sono, fadiga, imagem corporal); caminhada autorreferida; e testes para medir o percentual de gordura, circunferência da cintura, flexibilidade e amplitude do movimento ADM do ombro foram realizados. Resultados: Desemprego e aposentadoria foram associados à baixa ACR, assim como o uso de inibidores de aromatase ao invés de tamoxifeno. Sintomas depressivos, pior imagem corporal, maior circunferência da cintura, menor flexibilidade e ADM do ombro também foram associados à baixa ACR. A duração da caminhada, controlada por idade e índice de massa corporal (IMC), é um preditor de 13% da variância do VO2 pico nesta amostra. Conclusão: Tais fatores devem ser considerados na compreensão do perfil de ACR de sobreviventes de CM. Como a caminhada foi um preditor da variância do VO2 pico, deve ser recomendada atividade física para pacientes com CM em uso de hormonioterapia.

Introducción: El consumo de oxígeno (VO2 ) es indicativo de aptitud cardiorrespiratoria (ACR) y los niveles más bajos se relacionan con un mayor riesgo de mortalidad total entre las personas con cáncer cuya terapia puede tener consecuencias adversas sobre el sistema cardiovascular. Objetivo: Examinar las asociaciones de los resultados sociodemográficos, clínicos, antropométricos y variables funcionales informados por las pacientes con la ACR en 69 mujeres (55±10 años) e identificar si caminar es un predictor de la variación del VO2 máximo en esta población con cáncer de mama (CM). Método: Mujeres sobrevivientes de CM que recibieron terapia hormonal después de dos tipos de cirugía (conservadora y mastectomía) se sometieron a una prueba de ACR en un cicloergómetro para medir el VO2 máximo. Se aplicó un cuestionario que contenía datos sociodemográficos, clínicos, resultados informados por los pacientes (RIP) (síntomas depresivos, calidad del sueño, fatiga, imagen corporal) y caminata autoinformada y pruebas para medir el porcentaje de grasa corporal, la circunferencia de la cintura, la flexibilidad y el rango de movimiento (RoM) del hombro. Resultados: El desempleo y la jubilación se asociaron con una baja ACR, al igual que el uso de inhibidores de la aromatasa en lugar de tamoxifeno. Síntomas depresivos, peor imagen corporal, mayor perímetro de cintura, menor flexibilidad y RoM de los hombros también se asociaron con una baja ACR. La duración de la caminata, controlada por edad e índice de masa corporal (IMC), es un predictor del 13% de la variación del VO2 pico en esta muestra. Conclusión: Estos factores deben ser considerados para comprender el perfil de ACR de los sobrevivientes de CM. Como la caminata fue un predictor de la variación del VO2 pico, debe recomendarse actividad física para pacientes con CM en terapia hormonal.

Pilates and dance to patients with breast cancer undergoing treatment: study protocol for a randomized clinical trial - MoveMama study.

BACKGROUND: Breast cancer is a global public health issue. The side effects of the clinical treatment can decrease the quality of life of these women. Therefore, a healthy lifestyle is essential to minimize the physical and psychological side effects of treatment. Physical activity has several benefits for women with breast cancer, and Pilates solo and belly dancing can be an enjoyable type of physical activity for women with breast cancer undergoing clinical treatment. The purpose of this study is to provide a Pilates solo and a belly dance protocol (three times per week/16 weeks) for women undergoing breast cancer treatment and compare its effectiveness with that in the control group. METHODS: The participants will be allocated to either the intervention arm (Pilates solo or belly dance classes three times per week for 16 weeks) or a control group (receipt of a booklet on physical activity for patients with breast cancer and maintenance of habitual physical activity routine). The Pilates solo and belly dance classes will be divided into three stages: warmup and stretching, the main stage, and relaxation. Measurements of the study outcomes will take place at baseline; postintervention; and 6, 12, and 24 months after the end of the intervention (maintenance period). The data collection for both groups will occur with a paper questionnaire and tests covering general and clinical information. The primary outcome will be quality of life (EORT QLQ-C30 and EORT QLQ-BR23), and secondary outcomes will be physical aspects such as cardiorespiratory fitness (6-min walk test and cycle ergometer), lymphedema (sum of arm circumference), physical activity (IPAQ short version), disabilities of the arm (DASH), range of motion (goniometer test), muscular strength (dynamometer test) and flexibility (sit and reach test), and psychological aspects such as depressive symptoms (Beck Depression Inventory), body image (Body Image After Breast Cancer Questionnaire), self-esteem (Rosenberg), fatigue (FACT-F), pain (VAS), sexual function (FSFI), and sleep quality (Pittsburgh Sleep Quality Index). DISCUSSION: In view of the high prevalence of breast cancer among women, the implementation of a specific protocol of Pilates solo and belly dancing for patients with breast cancer is important, considering the necessity to improve their physical and psychological quality of life. Pilates solo and belly dancing are two types of physical activity that involve mental and physical concentration, music, upper limb movements, femininity, and social involvement. An intervention with these two physical activities could offer options of supportive care to women with breast cancer undergoing treatment, with the aim being to improve physical and psychological quality of life.

Factors associated with depression symptoms in women after breast cancer.

OBJECTIVE: To analyze the factors associated with the presence of depression symptoms in women after breast cancer. METHODS: Cross-sectional study with 181 women with breast cancer, aged 57.0 years (SD = 9.5), who were undergoing treatment or after treatment in the Oncology Research Center in Florianópolis, state of Santa Catarina, Brazil. The questionnaire comprised items addressing general and health information, economic level, anthropometric measures, depression symptoms (Beck Depression Inventory), self-esteem (Rosenberg Self-Esteem Scale), and body image (Body Image After Breast Cancer Questionnaire). Descriptive and inferential statistical analysis were performed by chi-square and Fisher's exact tests to verify association, Mann-Whitney U test to compare the groups and Poisson regression to identify the prevalence ratio of the factors associated with presence of depression symptoms (p < 0.05). RESULTS: We found an association between the presence of depression symptoms and the group of younger women (aged 40-60 years), those who had another disease besides cancer, those who had mastectomy surgery, those who suffered from lymphedema, and those who presented low-medium self-esteem. Less educated women presented more depressive symptoms, as did women with worse body image on the subscales of limitations, transparency, and arm concerns. CONCLUSIONS: Age, educational attainment, diagnosis of other diseases, type of surgery, lymphedema, self-esteem, and body image were factors associated with the presence of depression symptoms in Brazilian women after breast cancer. Health professionals should be aware of these relationships and try to detect depression symptoms earlier and improve the care they provide to these women.

Physical activity and quality of life in women with breast cancer - a cross-sectional study / Atividade física e qualidade de vida em mulheres com câncer de mama - um estudo transversal / Actividad física y calidad de vida en mujeres con cáncer de mama - un estudio transversal

INTRODUCTION: Breast cancer treatment can cause different side effects on the quality of life of women. Physical activity, in turn, can reduce these side effects. OBJECTIVE: To investigate the physical activity and quality of life of women during and after breast cancer treatment. METHODS: Sample of 174 women (57.0±9.5 years) during or after clinical treatment for breast cancer. Interview questionnaire composed of general information, physical activity (IPAQ short version) and quality of life (EORTC QLQ-C30 and BR23). For statistical analysis chi-squared test or Fisher's exact test, student's t-test for independent samples, Mann-Whitney U test and multiple logistic regression analyses (p <0.05). RESULTS: Most women did not achieve the physical activity guidelines, particularly those undergoing clinical treatment. Results showed longer walking time, moderate physical activity, vigorous physical activity, moderate + vigorous physical activity, and total physical activity among the women following completion of treatment. The quality of life scores were also higher among women after clinical treatment. Logistic regression indicated that every 10-minute increment to walking time results in a 19% decrease in the probability of worse functional capacity and a 26% decrease in the probability of worse symptoms associated with treatment side effects. CONCLUSION: During treatment, women with breast cancer undertake less physical activity and have worse quality of life. Walking appears to be an effective type of physical activity for these women, improving quality of life during and after breast cancer treatment. Level of evidence II; Prognostic studies - Investigation of the effect of patient characteristics on the disease outcome.

INTRODUÇÃO: O tratamento do câncer de mama pode causar diferentes efeitos colaterais na qualidade de vida das mulheres. A atividade física, por sua vez, pode diminuir esses efeitos colaterais. OBJETIVO: Investigar a atividade física e a qualidade de vida de mulheres durante e após o tratamento para câncer de mama. MÉTODOS: Amostra de 174 mulheres (57,0 ± 9,5 anos) durante e depois do tratamento de câncer de mama. Questionário de entrevista composto de informações gerais, atividade física (versão curta do IPAQ) e qualidade de vida (EORTC QLQ-C30 e BR23). Para a análise estatística foram usados Qui-quadrado ou Exato de Fisher, teste T de Student para amostras independentes, teste U de Mann-Whitney e análises de regressão logística múltipla (p < 0,05). RESULTADOS: A maioria das mulheres não atingiu as recomendações de atividade física, com destaque para as mulheres que estavam em tratamento clínico. Os resultados mostraram mais tempo de caminhada, atividade física moderada, atividade física vigorosa, atividade física moderada + vigorosa e atividade física total em mulheres após o término do tratamento. Os escores de qualidade de vida também foram mais altos entre as mulheres após o término do tratamento. A regressão logística indicou que cada acréscimo de 10 minutos no tempo de caminhada resulta em diminuição de 19% da probabilidade de capacidade funcional mais baixa e de 26% de desenvolver mais sintomas mais graves associados aos efeitos colaterais do tratamento. CONCLUSÃO: Durante o tratamento, as mulheres com câncer de mama praticam menos AF e têm pior qualidade de vida. A prática de caminhada parece ser um tipo efetivo de atividade física para essas mulheres, melhorando a qualidade de vida durante e depois do tratamento de câncer de mama. Nível de evidência II; Estudos prognósticos - Investigação do efeito das características do paciente sobre o desfecho da doença.

Benefits of belly dance on quality of life, fatigue, and depressive symptoms in women with breast cancer - A pilot study of a non-randomised clinical trial.

OBJECTIVE: To analyse the influence of belly dance on the quality of life, fatigue, and depressive symptoms in women with breast cancer. METHODS: Pilot study, with a design of non-randomised clinical trial study, analysing 19 women, with 8 allocated in the experimental group and 11 in the control group. The experimental group underwent 12 weeks of belly dance classes, with a frequency of twice a week and duration of 60 min for each lesson. Data collection was made through the use of questionnaires containing general information, quality of life (EORTC QLQ-BR23), fatigue (Piper Fatigue Scale) and depressive symptoms (BECK's Depression Inventory) applied on baseline and after intervention. RESULTS: The experimental group presented significant improvements after the intervention, with an increase in scores of the functional scale (p = 0.002): body image (p = 0.037) and sexual function (p = 0.027); and a decrease in scores of the symptomatic scale (p = 0.001): systemic therapy side effects (p = 0.005) and arm symptoms (p = 0.001) of quality of life, as well the decrease of fatigue (p = 0.036) and depressive symptoms (p = 0.002). No significant differences were observed in clinical and demographic information at baseline between the experimental and control groups. Also, there was no significant difference on quality of life, fatigue, and depressive symptoms between the two groups. CONCLUSION: Belly dance can be a viable form of physical activity for women with breast cancer. It was associated with benefits for quality of life, fatigue, and depressive symptoms. Even though there were significant pre-post treatment differences, there was no significance difference between the experimental and control group; and therefore, treatment could have been due to natural history.

Vertical ground reaction force in stationary running in water and on land: A study with a wide range of cadences.

PURPOSE: The aim of this study was to analyze the effect of cadence, immersion level as well as body density on the vertical component (Fymax) of ground reaction force (GRF) during stationary running (SR). METHODS: In a controlled, laboratory study, thirty-two subjects ran at a wide range of cadences (85-210 steps/min) in water, immersed to the hip and to the chest, and on dry land. Fymax. was verified by a waterproof force measurement system and predicted based on a statistical model including cadence, immersion ratio and body density. RESULTS: The effect of cadence was shown to depend on the environment: while Fymax increases linearly with increasing cadence on land; in water, Fymax reaches a plateau at both hip and chest immersions. All factors analyzed, cadence, immersion level and body density affected Fymax significantly, with immersion (aquatic × land environment) showing the greatest effect. In water, different cadences may lead to bigger changes in Fymax than the changes obtained by moving subjects from hip to chest immersion. A regression model able to predict 69% of Fymax variability in water was proposed and validated. CONCLUSION: Cadence, Immersion and body density affect Fymax in a significant and non-independent way. Besides a model of potential use in the prescription of stationary running in water, our analysis provides insights into the different responses of GRF to changes in exercise parameters between land and aquatic environment.

Velocidade crítica e índices de capacidade aeróbia na natação: uma revisão da literatura / Critical Swimming Speed and aerobic capacity index in swimming: A literature review

A relação entre desempenhos em diferentes distâncias com seus respectivos tempos fornece um válido, barato e prático índice de avaliação da capacidade aeróbia para natação. Este índice, conhecido como Velocidade Crítica, tem recebido muita atenção por pesquisadores, pois possibilita a substituição de outros indicadores de capacidade aeróbia que geralmente são caros ou demandam demasiado tempo do período de treinamento. No entanto, ainda não foi realizada uma compilação de estudos tratando da Velocidade Crítica com outros índices de capacidade aeróbia na natação. Assim, o objetivo desta revisão foi comparar a relação da Velocidade Crítica com outros índices de capacidade aeróbia comumente utilizados na natação como: Teste de 30 Minutos, Máximo Estado Estável de Lactato, Limiar Anaeróbio e Velocidade Aeróbia Máxima. Foi realizada uma busca bibliográfica nas bases de dados PubMed e SciELO, utilizando-se as seguintes palavras-chave: "Critical swimming speed", "critical swimming velocity" e "velocidade crítica and natação". Ao fim do processo de seleção foram incluídos 21 artigos para esta revisão. Foi observado que a relação da Velocidade Crítica com o Limiar Anaeróbio e o Teste de 30 Minutos é dependente da idade dos nadadores, requerendo cautela quando comparados. Também foi observado que a Velocidade Crítica superestima a intensidade do Máximo Estado Estável de Lactato e do Limiar Anaeróbio em nadadores adultos, indicando delimitar os domínios do exercício pesado e severo na natação. Contudo, a Velocidade Crítica pode ser influenciada pelas distâncias preditivas utilizadas para sua determinação, e assim, devem ser cuidadosamente selecionadas. Por fim, a Velocidade Crítica apresenta boa correlação com os principais índices aeróbios representando ser um bom parâmetro para avaliação da capacidade aeróbia em nadadores....(AU)

The relationship between distance covered and the time needed to cover it at maximal speed provide a valid, cheap and practice index to evaluate aerobic capacity in swimming. This index, known as Critical Swimming Speed, has received much attention for researchers, because it could replace other aerobic capacity indexes that usually are more expensive and demand more time of training. However, there is no compilation of studies involving Critical Swimming Speed and other aerobic capacity index on the literature. Hence, the purpose of this literature review was comparing the relationship between Critical Swimming Speed with others aerobic capacity indexes generally used in swimming as: 30-min Test, Maximal Lactate Steady State, Anaerobic Threshold and Maximal Aerobic Speed. The articles were surveyed on the scientific bases PubMed and SciELO using the following keywords: "Critical swimming speed", "critical swimming velocity" and "velocidade crítica and natação" (on Portuguese). At the end of the search process, 21 articles were included in the revision. It was observed that the relationship between Critical Swimming Speed with Anaerobic Threshold and 30-min Test is affected by the age of the swimmers, demanding caution when comparing these indexes. It was also observed that the Critical Swimming Speed overestimates the Maximal Lactate Steady State and Anaerobic Threshold in adult swimmers, which indicates a boundary between the heavy and severe intensity domains during swimming exercises. However, the predictive distances used for the Critical Swimming Speed determination may influence on its final value and, thus, they should be carefully selected. Lastly, Critical Swimming Speed shows a good correlation with major aerobic indexes and represents a good aerobic capacity parameter to evaluate swimmers....(AU)

Propulsive force symmetry generated during butterfly swimming / Simetria da força propulsiva gerada pelas mãos durante o nado borboleta

Abstract The aim of the study was to analyze the hand force symmetry in butterfly swimming. Fourteen male and female swimmers (18.4 ± 4.9 years old, 71.8 ± 14.6 kg of body mass, 1.78 ± 0.09 m of height and mean performance that corresponds to 74.9 ± 5.8% of the world record). Subjects performed three trials of 25 m of butterfly swimming at maximal speed. Mean and maximum forces were estimated for each hand using pressure sensors of the Aquanex System (Swimming Technology Research, USA). The comparisons between force values for dominant and non-dominant hands were made through Student’s T test for dependent samples (p<0.05). In addition, the symmetry Index (SI) was calculated as a relative measure of the force applied by each hand. The mean and maximum force for the dominant hand corresponded, respectively, to 55.7 ± 14.7 N and 114.7 ± 39.6 N. For the non-dominant hand, values were 51.2 ± 14.7 N for mean force and 110.7 ± 36.7 N for maximum force. Significant differences were found between dominant and non-dominant hands for both variables (p<0.01). The symmetry index analysis showed mean values of 8.9% for mean force and of 12.6% for maximum force, and most swimmers presented values higher than 10% for mean and/or maximum forces. Further studies should be performed in order to investigate the relationship between hand force symmetry and swimming performance.

Resumo O objetivo do estudo foi analisar a simetria da força dos membros superiores durante a braçada do nado borboleta. Quatorze nadadores de ambos os sexos (18,4 ± 4,9 anos, massa de 71,8 ± 14,6 kg, estatura de 1,78 ± 0,09 m e com média de desempenho correspondente a 74,9 ± 5,8% do recorde mundial) realizaram três execuções de 25 m máximas nadando borboleta. A força média e a força máxima de cada mão foram estimadas através de sensores de pressão do Sistema Aquanex (Swimming Technology Research, EUA). Comparações entre a força produzida pelos lados dominante e não dominante foram realizadas através do teste t de Student para amostras dependentes (p<0,05). Adicionalmente, foi calculado o índice de simetria como uma medida relativa da força aplicada em cada mão. A força média e a força máxima da mão dominante corresponderam, respectivamente, a 55,7 ± 14,7 N e 114,7 ± 39,6 N. Para a mão não dominante, os valores foram de 51,2 ± 14,7 N para a força média e 110,7 ± 36,7 N para a força máxima. Foram encontradas diferenças significativas entre a mão dominante e não dominante para ambas as variáveis (p<0,01). A análise do índice de simetria mostrou valores médios de 8,9% para a força média e de 12,6% para a força máxima, sendo que a maioria dos nadadores apresentou valores maiores do que 10%, para a força média e/ou máxima. Acredita-se que análises futuras devam ser feitas, buscando relações da assimetria com o desempenho de nado.

O salto vertical é uma habilidade motora fundamental na realização de inúmeras atividades cotidianas, na locomoção e no desempenho esportivo. É muito utilizado em jogos de corrida com paradas bruscas, nos jogos que exigem do equilíbrio, e em jogos tradicionais, podendo ser combinado com outras habilidades motoras. Dada a sua importância, pesquisas vêm sendo realizadas na tentativa de estabelecer um referencial teórico para sua compreensão. Levando em consideração a relevância dos estudos nessa linha de pesquisa, este estudo teve como objetivo reunir e analisar pesquisas com o salto vertical enquanto instrumento para estimativas de variáveis de desempenho, biomecânica e padrão motor. O levantamento, a análise e a seleção da produção científica aconteceram em quatro etapas: 1) busca simples de produções científicas sobre as tendências principais dos estudos, usando os descritores salto vertical, desempenho, biomecânica e padrão motor e suas traduções correspondentes; 2) delimitação do período de publicação entre 1980 e 2011 e nos idiomas inglês, espanhol e português; 3) análise preliminar da relevância do artigo, dissertações e teses aos termos investigados; 4) estudo minucioso do conteúdo, analisando-se criticamente a metodologia adotada e os resultados obtidos. As pesquisas foram agrupadas e apresentadas em tópicos de acordo com as variáveis do estudo. Essa revisão literária permitiu observar diferentes vertentes de interesse entre os autores, predominando os estudos sobre a aptidão física e o desempenho, e os estudos das habilidades motoras fundamentais. Observou-se também, uma sofisticação dos modelos mecânicos utilizados para análise do movimento, tendo os estudiosos da área, condições de aprofundar em mais seus modelos devido à utilização, cada vez mais especializada, do comando numérico computadorizado (CNC), tornando mais fidedigna as análises e favorecendo toda uma comunidade científica.

The vertical jump is a fundamental motor ability that enables to realize several routine activities, in locomotion and sports performance. The vertical jump is usually performed in games that involves running with sudden stops, balance and traditional games, also can be combined with other motor abilities. Considering its importance, researches have been performed trying to establish an agreement about the topic. Understanding the relevance that vertical jump studies has, this paper had as objective to gather and analyze researches involving the vertical jump as an instrument to estimate performance, biomechanical and motor patterns variables. The survey, the analysis and the selecting of the scientific production were made in 4 phases: 1) simple search of scientific papers about the main trends, using the keywords vertical jump, performance, biomechanics and motor patterns and its translated forms; 2) delimitation of the period of publication, between 1980 and 2011, written in English, Spanish and Portuguese; 3) preliminary analysis of the article, dissertation and thesis relevance; 4) detailed study about the contents, analyzing the method adopted and results found. The researches were separated and presented in topics according to the study variables. This bibliographic review allowed understanding the different lines of interest between the authors, with more emphasis in fitness and performance, and the studies of fundamental motor abilities. It was observed that the mechanic models used to do movement analysis was improved in the course of time, helping the researchers to improve their own models, using the Computer Numeric Control (CNC) with more expertise, presenting more trustworthy analysis, bringing more benefit to whole scientific community.
