Aerobic Fitness is a Predictor of Body Composition in Women With Breast Cancer at Diagnosis.

Background: The objective of this study was to investigate the relationship of aerobic fitness (AF) at diagnosis, before treatment and its relationship with body composition, physical function, lipidic profile, comorbidities, tumor characteristics, and quality of life of women with breast cancer (BC) PATIENTS AND METHODS: This cross-sectional cohort study included 78 women with BC that were assessed before treatment. A 6-minute walk test was used to evaluate the subjects' AF, estimating the maximum oxygen consumption (VO) to classify the women with BC into 2 groups: good/excellent AF or fair/weak/very weak AF. Dual-energy x-ray absorptiometry was performed to assess body composition.

Aerobic Exercise-Induced Changes in Cardiorespiratory Fitness in Breast Cancer Patients Receiving Chemotherapy: A Systematic Review and Meta-Analysis.

While performing aerobic exercise during chemotherapy has been proven feasible and safe, the efficacy of aerobic training on cardiorespiratory fitness (CRF) in women with breast cancer undergoing chemotherapy has not yet been systematically assessed. Therefore, the objective of this work was to determine (a) the efficacy of aerobic training to improve CRF; (b) the role of aerobic training intensity (moderate or vigorous) on CRF response; (c) the effect of the aerobic training mode (continuous or interval) on changes in CRF in women with breast cancer (BC) receiving chemotherapy. A systematic review and meta-analysis were conducted as per PRISMA guidelines, and randomized controlled trials comparing usual care (UC) and aerobic training in women with BC undergoing chemotherapy were eligible.
