Interventions
Participants will be divided into four groups of 15 through stratified randomization. Group 1 will receive intervention with multicomponent exercise training (EXC) for 16 weeks, followed by 16 weeks o
and strategies for motivation and behavioral change will be applied.

Eligibility
Age
60 Years to No maximum
Inclusion criteria
Inclusion criteria: Will be included in this study men and women aged from 60 years, with independent mobility (without using auxiliary devices), who are able to practice physical activities and who are not regularly participating in a systematic physical exercise program.
Exclusion criteria
Exclusion criteria: Will be excluded from the study, older adults with disabling osteoarticular diseases of the lower limbs; those who have insufficient cognitive function to understand the tests and exercises; who have undergone orthopedic surgery in the six months preceding the study; and that present some absolute contraindication to physical exercises.

| Physical activity level increase: The physical activity level will be assessed at baseline, after the intervention and after the follow-up period, directly and indirectly. The indirect assessment will be carried out using the Minnesota Leisure Time Activity questionnaire, translated and culturally validated for the Brazilian population (LUSTOSA et al., 2011), which assesses the level of physical activity, sport and leisure by calculating the average weekly energy expenditure. Additionally, the International Physical Activity Questionnaire (IPAQ) long version, validated and adapted for the Brazilian elderly (BENEDETTI et al., 2007), will be used. For direct measurement, Actigraph accelerometers, model GT3X, will be used, which record counts of daily activities, later translated into minutes of activity. Participants will be instructed to use the device on the ankle of the dominant leg for 7 days, removing only to sleep and to perform water activities, including bathing (HENDELMAN et al., 2000). The intensity of the activities will be interpreted based on the Freedson equation: sedentary activity (0 - 99 counts / minute), light activity (100 - 1951 counts / minute), moderate activity (1952 - 5724 counts / minute), vigorous activity (5725 - 9498 counts / minute) and very vigorous activity (5725 - 9498 counts / minute) (HENDELMAN et al., 2000). The mean variables of calories per day and the time spent on sedentary, light, moderate, vigorous and very vigorous activities will be analyzed. | — |

| Physical fitness and functionality enhancement: Functional mobility and dynamic balance will be assessed using the Timed Up and Go test, which consists of getting up from a chair, walking at the usual speed on a 3 meter linear path, returning and sitting down again (BOHANNON, 2006). Physical performance will be assessed through the Short Physical Performance Battery (SPPB), validated for the Brazilian elderly (FREIRE et al., 2012), consist of three tests that assess the standing static balance, gait speed and muscle strength of the lower members. Gait speed will be calculated from the time taken to walk at normal speed on a 4-meter linear path (GURALNIK et al., 1994). Muscle strength and power of the lower limbs will be assessed using the Five Times Sit-to-stand test, in which the subject must stand up and sit down in the chair again five times, as quickly as possible (BUATOIS et al., 2008). Each test receives a score of 0 to 4 points, depending on performance. The total score (sum of the three tests) varies from 0 to 12 points, with 0 indicating the worst physical function and 12 the highest level of this function (FREIRE et al., 2012). Aerobic fitness will be assessed using the 6-minute Walk Test, in which the individual have to walk the longest distance possible for 6 minutes on a 45.7-meter rectangular path (RIKLI; JONES, 1998). Flexibility will be assessed by the adapted sit and reach test (RIKLI; JONES, 1998), and by the reach behind the back test (RIKLY & JONES, 2001).;Cognitive function and memory enhancement Two questionnaires will be applied to assess mental health status, executive function and memory. Mini Mental State Examination, which assesses: spatial and time orientation, immediate memory, attention, evocation, language and visual constructive capacity (FOLSTEIN et al., 1975). The instrument's score ranges from 0 to 30 points; and the Montreal Cognitive Assessment, in its translated and validated version for the elderly Brazilian populatio | — |
