[Impact of exercise on the body composition and aerobic capacity of elderly with obesity through three models of intervention].
OBJECTIVE
The objective of this study was to analyze the influence of aerobic exercise on body composition and aerobic capacity of a sample of older, sedentary adults with obesity rates by three different models of intervention (recommendation, prescription at home and monitoring).


METHODS
A total of 76 older adults with a mean age 67.1+/-1.2 years, sedentary, with a BMI> 30 kg/ m2 were randomized in to four groups: Control (CON) recommendation (REC), prescription home (PRES) and monitoring in a sports center (MON). The same program of aerobic exercise for groups of home and sports center for 24 weeks, 3 days a week was developed. It was determined before and after the intervention BMI, Waist- Hip-index (ICC), the% fat ( Σ folds) and aerobic capacity (T6M) throughout the sample.


RESULTS
MON and PRES groups showed significant improvements in the ICC, Σ folds and T 6M variables, not the case in BMI. However the MON group presented significant differences from group PRES between-group analysis (p <0.001). The recommendation did not get positive effects.


CONCLUSIONS
Monitoring is the most effective exercise programs in adults with obesity methodology. However the exercise prescription at home since early intervention is an important approach for people with physical and/ or psychological reasons such as obesity cannot access the sports centers to participate in activities led by a monitor. Unknowns of aerobic exercise are cleared in the home that are of great impact for social policies regarding the health of the elderly population.
