The subjects doesn´t received 16 sessions (Two per week) of exercise with new tecnology between two measurements of the variable.

The intervention consists of 16 sessions, performed with a frequency of twice a week, the final evaluation was made within three days after the end of the last treatment session. It is used for the motor task, the "Fishing Under Zero" exercise, included within the "balance" modality and the so-called "Step Plus" located in the aerobic exercise folder. Each subject carried out the training taking into account the following methodology: 3 cycles of the "Fishing under zero" exercise, one cycle of the "Step Plus" exercise and 3 cycles of the "Fishing under zero" exercise, the approximate duration of the task being about 30 minutes.

This variable is obtained by performing two tests designed to quantify this cognitive function, using the E-prime computer program. Both tests are developed in the psychophysiology laboratory of the University of Seville. The first is to complete the "Test Oddball" and the second the "Attention Network Test-ELDERLY". Both tests measure the reaction times, in seconds and, the precision, in percentages. It involves two continuous quantitative measurements.

This variable is obtained from the score obtained in the scale called Miniexamen Cognitive (MEC), in which the subject must: respond to a series of questions that we perform related to the orientation, try to set a series of three words that the evaluator says to remember them later, develop a series of calculations, and work on a series of aspects related to language and its construction. At the end of the test, the subject obtains a score that determines the presence or absence of a cognitive problem. We consider it as a discrete quantitative variable.

This variable is studied using the Berg scale, which allows to quantify the balance of the subject in different positions, obtaining a global score that guides us on the general state of the balance function and guides us on a wheelchair dependence, the use of some technical help or total independence for the development of the march. We consider it as a discrete quantitative variable

This variable is configured by the application of the "Timed up and Go test" scale, which quantifies the time the subject takes to get up from a chair, walk 3 meters and return back to the starting position. We consider this variable as continuous quantitative
