Effect of concurrent training (aerobic+resistance) more static stretching on flexibility in women with breast cancer / Efeito do treinamento concorrente (aeróbio + resistência) mais alongamento estático na flexibilidade em mulheres com câncer de mama

Objective. was to assess flexibility in women with breast cancer who underwent concurrent training (aerobic+resistance) (CT) more static stretching. 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 more static stretching, concomitant to hospital treatment and 17 women for the control group (CG) who only underwent hospital treatment. The CT more static stretching 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 and the flexibility of the lower limbs was assessed through the sit-and-reach test. Data were analyzed using repeated measures ANOVA Test and Bonferroni Post-hoc using SPSS 21 software, with α of 5%. Results. The TG presented increased flexibility in the horizontal abduction of the right shoulder (p=0.001) and in the lower limbs (p<0.001), but the CG showed a reduction in the horizontal abduction of the right shoulder (p=0.003). The effect size for horizontal abduction of the right shoulder was medium (p=0.508) and for the lower limbs was large (p=0.839). Conclusion. CT more static stretching may be a therapeutic intervention to increase flexibility of upper and lower limbs in women with breast cancer. (AU)

Objetivo. Avaliar a flexibilidade em mulheres com câncer de mama que realizaram treinamento concorrente (aeróbio + resistência) (TC) mais alongamento estático. Métodos. Este foi um estudo piloto controlado, com 31 mulheres (de 30 a 59 anos) em tratamento para câncer de mama, 14 mulheres foram alocadas em um grupo de treinamento (GT) que realizaram TC mais alongamento estático, concomitante a tratamento hospitalar e 17 mulheres para o grupo de controle (GC) que somente realizaram tratamento hospitalar. O TC mais alongamento estático foram realizados em 12 semanas com 5 sessões semanais, três sessões (aeróbia + resistência) e duas sessões (exercícios de alongamento) em dias alternados. A flexibilidade do ombro foi medida por meio do goniômetro de pêndulo 360º Sanny e a flexibilidade de membros inferiores foi avaliada por meio do teste de sentar e alcançar. Os dados foram analisados usando o Teste ANOVA de medidas repetidas e Post-hoc de Bonferroni no software SPSS 21, com α de 5%. Resultados. O GT apresentou aumento da flexibilidade na abdução horizontal do ombro direito (p=0,001) e nos membros inferiores (p<0,001), mas o GC apresentou redução da abdução horizontal do ombro direito (p=0,003). O tamanho do efeito para abdução horizontal do ombro direito foi médio (p=0,508) e para membros inferiores foi grande (p=0,839). Conclusão. O TC mais alongamento estático podem ser uma intervenção terapêutica para aumentar a flexibilidade de membros superiores e inferiores em mulheres com câncer de mama. (AU)

Impact of home-based aerobic training combined with food orientation on food consumption, daily physical activity and cardiorespiratory fitness among breast cancer survivors: six-month clinical trial

ABSTRACT BACKGROUND: Anticancer treatment gives rise to adverse effects such as increased pain and changes to body weight and menstrual cycles, with negative effects on activities of daily living. OBJECTIVE: To analyze the effect of food orientation combined with supervised (face-to-face, FF) versus home-based (HB) aerobic training on lifestyle (food consumption and daily physical activity (PA) levels), body composition, metabolic profile and cardiorespiratory fitness, among breast cancer survivors. DESIGN AND SETTING: Clinical trial study (six months) conducted at a public university in Presidente Prudente, Brazil. METHODS: Twenty-three female breast cancer survivors (40-75 years old) were allocated to aerobic training groups, either FF or HB. Both groups were trained and received food orientation. They were evaluated through a dietary record, ergometric treadmill test and blood test and the Baecke questionnaire. RESULTS: After six months, both groups had reduced their lipid levels, total energy consumption and polyunsaturated fat intake, and had increased their PA levels and treadmill test durations. However, only the HB showed reduced carbohydrate percentage and increased folic acid; and only the FF showed reduced lipid, saturated fat and sodium levels, along with increased carbohydrate and protein levels. No differences in body composition or metabolic profile were found. CONCLUSIONS: These results demonstrated the feasibility of HB aerobic training. In isolation, HB showed greater regulation of carbohydrate percentage and increased folic acid levels. Moreover, these breast cancer survivors presented improvements in food consumption, PA levels and cardiorespiratory fitness, while also maintaining their body composition and metabolic profile after the intervention, independent of the group.
