Efeitos do treinamento resistido sobre aspectos cineantropométricos, hematológicos, bioquímicos e biofisicoquímicos em sobreviventes de câncer de mama

Abstract

Significant increase in survival rate has occurred in women diagnosed with breast cancer. This requires the improvement of strategies aimed at accompanying and managing this public. Thus, this research aimed to investigate the effects of re-sistance training (RT) on muscular strength, anthropometric and hematologic char-acteristics, and biophysicochemical aspects in breast cancer survivors (BCS). Twenty-two women participated voluntarily. Measurements were performed before and after the training period and the results of each variable were compared (pre-RT vs. post-RT) and correlated (pre-RT and post-RT). Statistical treatment in-volved the Shapiro-Wilk test, the paired t-test or the Wilcoxon test, and the Spear-man correlation. The level of significance was 5%. Statistically significant results indicated increased muscle strength in all tested exercises, including upper limbs exercises; reduction of the percentage of body fat (p=0.004) and increase of the percentage of lean mass (p=0.008); reduction of erythrocytes (p=0.009) and plate-lets (p=0.025) counts, and hemoglobina levels (p=0.014); increase in HDL-C (p=0.000) and reduction of total cholesterol (t-C) (p=0.013), LDL-C (p=0.003), LDL-C/HDL-C (p=0.000), and VLDL-C (p=0.044); besides reduction in the osmotic sta-bility of the erythrocyte membrane (p=0.039). In addition, many significant correla-tions were observed between the variables at both moments of analysis. Taken together, these data highlight the preservation of responsiveness of BCS to the exercise and the benefits of RT in various health indicators. The hematologic changes reported here indicate the importance of frequent monitoring of BCS, in-cluding ensuring the improvement of interventions with RT.
