Patients allocated to the intervention group will perform a MPEP during 6 months, with a frequency of 3 sessions per week, and approximately 45-50 minutes of duration each session. In addition, they will have a Mediterranean Diet.

The patients in the MPEP will be carried out in small groups of 5-8 people. Structure of sessions: 3 different parts: an initial warm-up, a main part and a final cool-down and relaxation.

Participants allocated to the control group will receive usual care and continue with their life normally, without participating in a standardized exercise program. They will be instructed to maintain their current physical activity level.

In this basic structure of each sessions, traditional exercises of mobility, strength, balance and coordination are included with the main objective of improving functional capacities. But, besides, games and some activities are also included with the aim, not only of improving the functional capacity, but also working the cognitive functions to reinforce the global effects.

The Mediterranean diet will based in these main foods: 1) vegetables; 2) fruits; 3) fish or seafood; 4) legumes; 5) nuts; 6) bread or cereals; 7) white meat; 8) eggs; and 9)olive oil.

Tinetti's Performance Oriented Mobility Assessment (POMA-T) will be used (points). the original POMA-T 28-point version. It consists of a balance scale (Balance performance oriented mobility assessment (POMA-B) can score 16 points) and a gait scale (Gait performance oriented mobility assessment (POMA-G) can score 12 points )

Timed up and go test (TUG) will be used (s). IT measures the time in seconds for the subjects to get up from a standard armchair, walk 3 metres, turn, walk back to the chair and sit down. The cut-off point for normal mobility is 12 seconds and values > 30 s indicate a high level of dependence. (a time <10s it is considered normal; <20s mobility difficulties and low or moderate risk of falls; > 20 mobility problems with need of help and high risk of falls)

Bone health status will be assessed by ultrasound calcaneus densitometry/sonometry. As primary outcome we will assess the estimated BMD (g/cm2).

Bone health status will be assessed by ultrasound calcaneus densitometry/sonometry. As primary outcome we will assess the T-Score. A T-score shows how much the BMD is higher or lower than the BMD of a healthy 30-year old adult. (-1.0 or above normal BMD; From -1.0 to -2.5 low BMD or osteopenia; -2.5 or below very low BMD and diagnosis of osteoporosis.

one-leg balance test (OLB) will be used (s). This test assess the ability of the patients to remain upright on one leg without support for at least 5 seconds, and each leg was tested.
