PurposeTo 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.MethodsA 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.ResultsPatients 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).ConclusionCombined training was effective in decreasing pain and increasing VO2 max, flexibility and static strength in patients with breast cancer.Trial registrationNCT03061773.

RESUMOIntrodução: Um adequado estado de hidratação é de suma importância para os participantes de corridas de rua, tanto para um melhor desempenho esportivo, quanto na prevenção dos distúrbios causados pelo calor. Objetivo: O estudo visa avaliar o estado de hidratação de indivíduos do sexo masculino em corrida de rua de 15 km. Métodos: A amostra foi composta por 15 indivíduos do sexo masculino (37,67±7,22 anos) praticantes habituais de corrida de rua. O estado de hidratação foi avaliado antes e após a corrida através dos seguintes parâmetros: peso corporal, coloração e gravidade específica da urina (GEU), análise da impedância bioelétrica (BIA), níveis de hemoglobina (Hb) e hematócrito (Ht). Na análise dos dados, foi utilizado o teste t de Student pareado ou o teste de Wilcoxon, aceitando-se como estatisticamente significante p < 0,01. Resultados: Houve diminuição do peso corporal dos indivíduos após a corrida (p<0,0001), assim como elevação dos níveis de Hb e Ht. Apesar da diminuição observada na GEU após o exercício, não houve melhora significativa do padrão de coloração da urina ou diferença entre o conteúdo inicial e final de água corporal total. A temperatura ambiente (TA) e umidade relativa do ar (URA) foram de 38,75±1,79°C e 37,37±4,66%, respectivamente. Conclusão: O exercício no ambiente em questão conduziu os indivíduos a um estado de desidratação, apenas detectado pela análise da variação do peso corporal e de parâmetros sanguíneos através dos níveis de Hb e Ht. Parâmetros urinários como a coloração da urina e GEU, assim como aqueles obtidos através da BIA, provavelmente foram confundidos por variáveis não controladas pelo presente estudo.

Objective. was to assess flexibility in women with breast cancer who underwent combined training (CT) (static stretching, more aerobic+resistance).
Methods. This was a controlled pilot study, with 31 women (age 30 to 59) under breast cancer treatment, 14 women were allocated to a training group (TG) who underwent CT, concomitant to hospital treatment and 17 women for the control group (CG) who only underwent hospital treatment. The CT was performed in 12 weeks with 5 sessions per week, three sessions (aerobic+resistance) and two sessions (stretching exercises) on alternate days. The flexibility of the shoulder was measured by means of the 360º Sanny pendulum goniometer.
Results. The TG presented increased flexibility in the horizontal abduction of the right shoulder (p=0.001) and in the lower limbs (p
