ABSTRACT

OBJECTIVE: Evaluate the effect of combined training on body image (BI), body composition and functional capacity in patients with breast cancer. As also the relationship of BI with body composition and functional capacity. METHODS: This was a Controlled Clinical Trial study, this study including 26 patients with breast cancer (30 to 59 years). The training group (n = 13) underwent 12 weeks of training, including three 60-min sessions of aerobic exercise and resistance training, and two sessions of flexibility training per week; each flexibility exercise lasted 20s. The Control Group (n = 13) received only the standard hospital treatment. Participants were evaluated at baseline and after 12 weeks. BI (primary outcomes) was assessed using the Body Image After Breast Cancer Questionnaire; Body composition was estimated with the indicators: Body mass index; Weight, Waist hip Ratio; Waist height ratio; Conicity index; Reciprocal ponderal index; Percentage of fat; Circumference of the abdomen and waist; Functional capacity by cardiorespiratory fitness (cycle ergometer) and strength (manual dynamometer). The statistic was performed in the Biostatistics and Stata 14.0 (α = 5%). RESULTS: The patients in the training group showed a reduction in the limitation dimension (p = 0.036) on BI, However, an increase in waist circumference was observed in both groups. In addition an increase in VO2max (p < 0.001) and strength in the right (p = 0.005) and left arms (p = 0.033). CONCLUSION: Combined training demonstrates to be an effective and non-pharmacological strategy to patients with breast cancer, with improvement on BI and functional capacity, changing related variables negatively when there is no physical training.

Assim como a relação do IB com a composição corporal e capacidade funcional. MéTODOS:: Este foi um estudo de Ensaio Clínico Controlado, este estudo incluiu 26 pacientes com câncer de mama (30 a 59 anos). O grupo de treinamento (n = 13) foi submetido a 12 semanas de treinamento, incluindo três sessões de 60 min de exercício aeróbio e treinamento de resistência, e duas sessões de treinamento de flexibilidade por semana; cada exercício de flexibilidade durou 20s. O Grupo Controle (n = 13) recebeu apenas o tratamento hospitalar padrão. Os participantes foram avaliados no início e após 12 semanas. O IB (desfechos primários) foi avaliado por meio do Body Image After Breast Cancer Questionnaire; A composição corporal foi estimada com os indicadores: índice de massa corporal; Peso, relação cintura-quadril; Relação da altura da cintura; Índice de conicidade; Índice ponderal recíproco; Porcentagem de gordura; Circunferência do abdômen e cintura; Capacidade funcional por aptidão cardiorrespiratória (cicloergômetro) e força (dinamômetro manual). A estatística foi realizada na Bioestatística e no Stata 14.0 (α = 5%). RESULTADOS: Os pacientes do grupo de treinamento apresentaram redução da dimensão da limitação (p = 0,036) no IB, porém, foi observado aumento da circunferência da cintura em ambos os grupos. Além disso, um aumento do VO2máx (p <0,001) e da força nos braços direito (p = 0,005) e esquerdo (p = 0,033). CONCLUSãO:: O treinamento combinado demonstra ser uma estratégia eficaz e não farmacológica para pacientes com câncer de mama, com melhora do IB e da capacidade funcional, alterando variáveis relacionadas negativamente quando não há treinamento físico.

ABSTRACT

PURPOSE: To assess the influence of combined training on pain, fatigue, maximal oxygen uptake (VO2 max), body mass index (BMI), flexibility, and strength in patients with breast cancer. METHODS: A controlled pilot study with 28 patients undergoing chemotherapy, radiation therapy, and clinical observation in a renowned cancer treatment center; the patients were aged from 30 to 59 years old and were not engaged in physical training for three months previously. The Study Group (SG) underwent 12 weeks of training, including three 60-min sessions of aerobic exercise and resistance training, and two sessions of flexibility training per week; each flexibility exercise lasted 20 s and was performed in sets of three repetitions. The Control Group (CG) received only the standard hospital treatment. Participants were evaluated at the beginning of the study to establish a baseline and reevaluated at the end of 12 weeks. RESULTS: Patients in the SG showed a significant decrease in total pain points (p = 0.0047), pain intensity (p = 0.0082), and the extent to which pain interfered with their daily life (p = 0.0047). There was an increase in maximum oxygen uptake (p = 0.0001), flexibility (p = 0.0001), and strength on both sides (right p = 0.0001 and left p = 0.0008). No significant differences were observed in fatigue (p = 0.0953) or BMI (p = 0.6088). CONCLUSION: Combined training was effective in decreasing pain and increasing VO2 max, flexibility and static strength in patients with breast cancer. TRIAL REGISTRATION: NCT03061773 .

ABSTRACT

OBJETIVOS: Relatar a evolução de uma paciente sobrevivente de neoplasia da mama após ter sido submetida a treinamento aeróbico durante oito semanas. DESCRIÇÃO DO CASO: Uma paciente com 47 anos, tendo sido submetida à mastectomia por neoplasia da mama há cerca de cinco anos, seguida por radioterapia e quimioterapia, realizou treinamento aeróbico em cicloergômetro e esteira ergométrica durante oito semanas, com duas sessões semanais e aumento gradativo do volume de treino. Avaliações da capacidade cardiorrespiratória, da força estática, mobilidade superior, nível de atividade física e composição corporal foram realizadas antes e após o protocolo de treinamento. A paciente demonstrou melhora na fração de ejeção do ventrículo esquerdo, diminuição da frequência cardíaca de repouso e de esforço e aumento da amplitude de movimento do ombro e no nível de atividade física. Foi detectada também diminuição da gordura corporal visceral. Não houve aumento da força muscular nem da capacidade máxima de oxigênio. CONCLUSÕES: Este relato demonstra que no caso dessa paciente, submetida a tratamento cirúrgico, radioterápico e quimioterápico para câncer de mama, foram constatados benefícios na capacidade cardiorrespiratória, na mobilidade dos membros superiores, no nível de atividade física e na composição corporal, após treinamento aeróbico durante duas sessões semanais por oito semanas.


AIMS: To report the evolution of a breast cancer survivor after an eight-week aerobic training program. Case DESCRIPTION: A 47-year-old breast cancer patient, submitted to mastectomy about five years before, followed by radiation therapy and chemotherapy, was submitted to aerobic training on cycle ergometer and treadmill for eight weeks, two sessions per week, with gradual increase in training volume. Cardiorespiratory capacity, static strength, upper body mobility, level of physical activity, and body composition were assessed before and after the training protocol. The patient demonstrated improvement in left ventricular ejection fraction, decrement of heart rate at rest and during exercise, and increase in shoulder range of motion and in physical activity level. A reduction of visceral fat was also observed. There was no improvement in muscle strength or in maximum capacity of oxygen use. CONCLUSIONS: This case report describes improvements in cardiorespiratory capacity, in shoulder range of motion, in the level of physical activity, and in body composition, after an eight-week aerobic training (two weekly sessions), in a breast cancer patient who had undergone mastectomy, radiation therapy, and chemotherapy.

ABSTRACT

A obesidade atualmente é considerada uma epidemia mundial devido à relação direta com a inflamação sistêmica, doenças cardiovasculares e metabólicas, sendo o principal fator de risco para desenvolvimento de resistência a insulina e diabetes tipo 2. O excesso de tecido adiposo e o consumo elevado de gorduras são um dos principais fatores para a ativação de vias bioquímicas inflamatórias que causam prejuízos na sinalização intracelular da insulina. A captação de glicose para os tecidos é constituída por varias etapas onde as adipocinas secretadas pelo tecido adiposo principalmente o TNFα e os ácidos graxos livres, provenientes do consumo elevado de gorduras, são capazes de ativar proteínas inflamatórias como c-jun N-terminal kinase (JNK), Ikappa kinase (ikK), fator de transcrição kB (NF-kB) e assim alterar a sinalização da insulina diminuindo a entrada de glicose para as células. Evidências científicas mostram que o exercício físico aumenta a captação de glicose por uma via distinta a da insulina sendo dependente da ativação de proteína quinase ativada por AMP (AMPK) e diminui a expressão de proteínas inflamatórias. Com isso o objetivo desta revisão é descrever os possíveis mecanismos moleculares para o desenvolvimento da resistência a insulina associado a obesidade e os efeitos anti-inflamatórios do exercício físico. Foi realizada uma revisão de literatura tendo como fontes de pesquisa artigos nacionais e internacionais na base de dados pubmed e scielo tendo como critério de inclusão, artigos publicados nos últimos dez anos. Concluímos que a obesidade aliada ao consumo elevado de gorduras ativam proteínas inflamatórias capazes de alterar etapas na sinalização da insulina levando a um estado hiperglicêmico onde o exercício físico possui efeitos anti-inflamatórios por suprimir a atividade destas vias e aumentar a expressão de proteínas chave na captação de glicose.


Obesity is now considered a global epidemic due to the relationshipdirectly with systemic inflammation, cardiovascular and metabolic diseases, being the mainrisk factor for the development of insulin resistance and type 2 diabetes excessfat and high intake of fats are a major factor for activationinflammatory biochemical pathways that cause damage in the intracellular insulin signaling. Theglucose uptake into the tissues consists of several steps where the adipokines secretedmainly by adipose tissue TNFa and free fatty acids, derived from consumptionhigh fat, N-terminal are able to activate inflammatory proteins such as c-junkinase (JNK), Ikappa kinase (IKK), transcription kB (NF-kB) factor and thus alter the signalinginsulin decreasing the influx of glucose into the cells. Scientific evidence showsthat exercise increases glucose uptake through a pathway distinct from the insulin beingdependent on the activation of AMP-activated protein kinase (AMPK) and decreases the expression ofinflammatory proteins. Therefore, the objective of this review is to describe the possible mechanismsMolecular for the development of insulin resistance associated with obesity and the effectsanti-inflammatory exercise. A literature review was conducted as sources havingnational and international research articles in the database as having pubmed and scieloinclusion criteria, articles published in the last ten years. We conclude that the obesitycoupled with high consumption of fats activate inflammatory proteins capable of altering stepsin insulin signaling leading to a hyperglycemic state where the exercise hasAnti-inflammatory effects by suppressing the activity of these pathways and increase expression of proteinsKey in glucose uptake.

ABSTRACT

PURPOSE: To investigate the protective effects of pentoxifylline against lung injury observed after dorsal scald in aged animals. METHODS: Adult (eight months old) and aged (20 months old) rats were subjected to thermal injury or sham procedure. The six hours post-trauma animals received pentoxifylline and after 24 hours were euthanatized and lung tissue samples collected. The bronchoalveolar lavage fluid was evaluated for total protein content and tumor necrosis factor-alpha cytokine. Malondialdehyde and myeloperoxidase activity in the lung homogenate were measured and a histological lung examination was undertaken. RESULTS: Burn injury induced oxidative stress in lung homogenate was higher in elderly-burned rats compared to adult-burned rats (p<0.001). Total protein and cytokine in bronchoalveolar lavage increased in the elderly-burned group when compared to the adult-burned group (p<0.001). All parameters decreased in both groups treated with pentoxifylline (p<0.05). CONCLUSIONS: The injury was augmented in elderly rats when compared to adult rats. Damage was reduced with the use of pentoxifylline, however further studies are needed to evaluate the dose-response of the drug.

ABSTRACT

O objetivo do estudo foi analisar as respostas hormonais, imunológicas e enzimáticas agudas a uma partida de basquetebol em jogadores profissionais desta modalidade. A amostra foi composta de oito atletas de basquetebol, praticantes a pelo menos quatro anos. Foi realizada uma partida de duração total de 40 minutos com simulação real, sendo dividida por dois tempos de 20 minutos e um intervalo de 10 minutos entre os tempos. As amostras sanguíneas foram colhidas antes e imediatamente após a partida (20 ml pelo sistema de tubos a vácuo). As variáveis analisadas foram: hormônios testosterona e cortisol, leucócitos totais, neutrófilos, linfócitos, monócitos e as enzimas creatina kinase (CK) e lactato desidrogenase (LDH). Para análise estatística, foi utilizada estatística descritiva e Teste t de Student pareado com p≤0,05. A concentração pré (13,34 nmol/L e 301,97 nmol/L) e pós (17,34 nmol/L e 395,91 nmol/L) de testosterona e cortisol foram estatisticamente diferentes, com maiores valores após o jogo para ambos os hormônios respectivamente. A contagem das células imunes apresentou diferença significante nos leucócitos totais (6393,75 nmol/L e 9158,75 nmol/L) e neutrófilos (3532,5 nmol/L e 6392,62 nmol/L) com maiores valores após a partida. As variáveis enzimáticas analisadas não apresentaram diferenças significativas. Portanto, dos marcadores analisados, testosterona e cortisol mostraram aumento acentuado após a partida, o mesmo comportamento foi verificado para os leucócitos totais e neutrófilos.


The objective of the present study was to analyze the acute hormonal, immunological and enzymatic responses of professional basketball players to a basketball game. The sample was composed of eight basketball athletes, with a minimum of 4 years’ experience in basketball. A real game was simulated with a total duration of 40 minutes, divided into two halves of 20 minutes each and an interval of 10 minutes between halves. Blood samples were collected before and immediately after the game (20 ml, vacuum tube system). The variables analyzed were: testosterone and cortisol hormones, total leukocytes, neutrophils, lymphocytes, monocytes and the enzymes creatine kinase (CK) and lactate dehydrogenase (LDH). Statistical analysis was with descriptive statistics and the Student’s t test for paired samples to p≤0.05. The pre (13.34 nmol/L and 301.97 nmol/L) and post game (17.34 nmol/L and 395.91 nmol/L) levels of testosterone and cortisol were statistically different, with higher levels after the game for both hormones. The immune cell counts exhibited significant differences for total leukocytes (6393.75 nmol/L and 9158.75 nmol/L) and neutrophils (3532.5 nmol/L and 6392.62 nmol/L), with levels being higher after the game. No statistical differences were observed for the enzymatic variables. Therefore, based on the markers analyzed, testosterone and cortisol exhibited pronounced increases after the game and the same behavior was observed for total leukocytes and neutrophils.
