The aim of this study is to investigate the effect of a 6-months program of Adapted Physical Activity (APA) on lifestyle, physical activity levels, insulin resistance and adipokines, oxidative stress, microcirculatory haemodynamics and serum levels of specific circulating miRNA in post-menopausal, physically inactive breast cancer patients in oncologic follow-up with or without hormone therapy that had completed adjuvant treatment (radiotherapy and/or chemotherapy) .
Furthermore, the study will determine the impact of APA on functional capabilities, on self-reported physical activity, quality of life and psychic health.

This is a randomized controlled double-group assignment study with intermedial switch-over including post-menopausal, physically inactive breast cancer patients in oncological follow-up with or without hormone therapy, that had completed adjuvant post-surgical treatment (radiotherapy and/or chemotherapy) from at least 3 months and from not more than 3 years.
Patients in hormonal therapy and patient not in hormonal therapy will be assigned in two different groups, each one of 50 patients. In each groups, patients will be randomized divided in a control group (25 pt) and in a 6 months-physical training group (25 pt). After 6-months patient in control group will be switched in the physical training group.
The duration of the study is 2 year. Clinical evaluation of the patients will be made: at the enrollment, after 6, 12, and 24 months.
Physical activity will be adapted according to arm and shoulder morbidity, after fracture risk assessment. Exercise will be concentrated solely on leg muscles (pedalling on a cycle or bed ergometer) in individuals with limitations in the range of motion of the arms (eg, due to breast, axillary, or thoracic surgery). In patients experiencing ataxia, dizziness, or peripheral neuropathy, walking outdoors and mostly cycle-ergometry training will be preferred to other activities that also involve large muscle groups but require additional balance and coordination (eg, treadmill walking, outdoor cycling).
Exercises will be performed at the Unipolar Spinal Unit of "S. Maria della Misericordia" Hospital, Perugia.
The aim of the study is to confirm the positive effect of APA on metabolic stress, body mass composition, functional capacity, serum levels of specific circulating miRNA and quality of life in breast cancer patients in oncological follow-up.
Currently, only few data are available about the relationship between physical activity and microcirculatory hemodynamics that, together with oxidative stress, could be involved in genesis and progression of breast cancer.

Patients involved in the 6 months-physical training group.
The exercise intervention consists of 60 minutes sessions, divided into 40 minutes of aerobic exercise and 20 minutes of circuit training for muscular strength and flexibility exercises.
Aerobic exercise is performed using treadmill, exercise bikes, syncro and arm-ergometers, gradually increasing the exercise intensity, after a 10 minutes period of warming-up, to 60-80 % of Maximum Heart Rate.
Resistance training consists of resistance exercises for large muscle groups, performed with body weight-exercises and isotonic machines.
No Intervention: Control
Patients in control group carry on their usual follow-up programme.
- Change in physical activity levels [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Self reported physical activity, using IPAQ-SF (International Physical Activity Questionnairev - Short Form) score
- Change in BMI [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Reduction of BMI expressed as body mass (kg) / height^2 (m^2)
- Change in Post-Occlusive Reactive Hyperemia (PORH) [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Improvement of Area of Hyperemia (AH) at Post-Occlusive Reactive Hyperemia (PORH) on Laser Doppler velocimetry (Periflux System 5000, Perimed), expressed as Perfusion Units (PU).
- Carotid intima-media thickness (IMT) [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Improvement of macrovascular structures, that will be explored by carotid intima-media thickness (IMT) (two-dimensional B-mode ultrasonography), measured in mm.
- Arterial stiffness [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Reduction of arterial stiffness, that will be evaluated by radial applanation tonometry (SphygmoCor) and general transfer function assessing PWV (measure in m/s).
- Hemorheological profile [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Improvement of Hemorheological profile, that will be studied with Serum, Plasma, and Blood Viscosity (Haake rotational viscometer), measured as mPas.
- Serum adiponectin [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Improvement of serum adiponectin, measured by ELISA-method (ng/ml). Blood samples will be collected in the morning between 7:00 and 9:00 am, after overnight fasting.
- Serum IGF-1 [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]Improvement of serum IGF-1, measured by ELISA-method (ng/ml). Blood samples will be collected in the morning between 7:00 and 9:00 am, after overnight fasting.

- HOMA-IR index [ Time Frame: Evaluation baseline and after 6, 12 and 24 months from enrollment. ]
Homeostatic model assessment (HOMA) for insulin resistance (IR) is a method for assessing β-cell function and insuline resistance from basal (fasting) glucose and insulin or C-peptide concentrations. HOMA-IR can be calculated with a simple mathematical approximation as HOMA-IR = (FPI × FPG)/22.5, where FPI is fasting plasma insulin concentration (mU/l) and FPG is fasting plasma glucose (mmol/l), or as HOMA-IR = (FPI × FPG)/405 if fasting plasma glucose is expressed in mg/dl.
Values bethween 3 and 5 are considered expression of moderate insuline resistance; values upper 5 are considered expression of severe insuline resistance.
Improvement of insulin-sensitivity expressed as HOMA-IR index reduction.
