The prescription of physical activity for breast cancer survivors depends on the evidence that can be obtained as well as on the physiological, psychological and biological impact that physical activity may have in the reduction of relapse risk. Objectives: the purpose of this article is to review the different studies that have been published on the effect of exercise in breast cancer patients who had finished their radiation therapy and chemotherapy treatment to identify the intensity, frequency, duration of the exercise program, duration of the exercise sessions, type of physical activity and the different variables evaluated. Methods: a review of the experimental studies on this subject published from 1995 was conducted, 27 studies were included and the duration, frequency, intensity, duration of exercise sessions, intervention time and effects were examined. Results: seven studies (58%) conducted 24 week exercise programs, six studies (50%) proposed 3 exercise sessions per week, the exercise sessions of five (41%) studies lasted 30 minutes and the intensity of three studies (25%) was 50-80% of the MHR. Six studies (50%) evaluated the BMI, the body fat percentage and the quality of life, five studies (41%) evaluated the VO2 max., and two studies (16%) used tumor markers. Conclusions: the intensity, volume, frequency and duration with the best physiological impact on breast cancer survivors could not be determined. Likewise, the impact of physical activity on tumor markers was not established.
