Physical Exercise for Breast Cancer Survivors: Face-to-face Versus Home-based

Pilot Study of Supervised Adapted Physical Exercise in Women With Breast Cancer After Treatment - Face-to-face Context vs Online Home Based

The present investigation is a pilot feasibility study that aims to compare a physical exercise intervention in a face-to-face context (considered state of the art) with a physical exercise intervention in a distance context (online), both supervised, in women, of legal age, physically inactive, breast cancer survivors after primary treatment with curative intent.

Before and after the intervention these women will have a physical and functional assessment, as well as a pre-trial cardiopulmonary exercise test, to check if there are safety conditions to participate and also to self tailor the exercise prescription.

The prescription follows the ACSM´s exercise guidelines for cancer survivors and will comprise a 8 week combined exercise training, 3 times per week, in which two of them will be supervised and the third session of the week (cardio session) won´t.

Chat´s and weekly personal messages, as well as education, will be used to promote retention and exercise adherence.

Inclusion Criteria:

• Women
• Over legal age
