Effects of home-based exercise training on VO2 in breast cancer patients under adjuvant or neoadjuvant chemotherapy (SAPA): a randomized controlled trial.

Background: Breast cancer chemotherapy is associated with a decline in measured cardiorespiratory fitness and increased fatigue. Physical activity has emerged as a feasible intervention to limit these side effects. Quantitative evaluation is necessary to propose a better-adapted physical activity and to evaluate efficacy.
