Interventions
In the first part of the study, participants will be divided in two groups of 15. The volunteers of the experimental group (EG) will participate in a multicomponent home-based exercise program for 12
balance exercises
flexibility
walking and dual task activities, based on the recommendations of Singh (2002) and ACSM (2009). Each session will be divided into 05 minutes of dynamic movements and joint warm-up, with wide-ranging e
followed by 10 minutes of specific exercise of dynamic and static balance, with manipulation of visual information (eyes open and closed), reduction of the support base, stationary gait and displaceme
and activities with motor and cognitive tasks performed simultaneously
followed by 25 minutes of muscle strengthening exercises for lower and upper limbs
10 minutes for specific gait exercises
and 10 minutes of flexibility activities, with relaxation and stretching of the large muscle groups of the upper, lower limbs and trunk.
The second experimental group (GCOM) will participate in weekly

Eligibility
Age
60 Years to No maximum
Inclusion criteria
Inclusion criteria: Men and women; aged 60 years or over; who are independent in carrying out basic daily activities; who do not have absolute restrictions on the practice of physical activities.
Exclusion criteria
Exclusion criteria: Older adults with physical or motor limitations that make it impossible to perform functional tests; with a recent history of stroke; heart failure; those who use a pacemaker; who do not control unstable medical conditions (eg diabetes mellitus and hypertension); with neurological disease; with severe osteoporosis (with a history of two or more fractures); those who do not walk independently and need to use orthosis for locomotion.
Design outcomes

| Measure | Time frame |

| Increased physical activity and reduced sedentary behavior: For the measurement of the physical activity level, the volunteers will be instructed to use a Smartwatch (Xiaomi Mi Band 4) on the wrist of the dominant hand together with an accelerometer (ActiGraph GT3X-BT) for 7 consecutive days, being instructed to remove the devices only to carry out activities involving water (bathing) and to sleep. At the end of the 7-day period, the devices will be collected during a home visit. The variables will be analyzed: average daily caloric expenditure, time in sedentary activities, light activities, moderate activities, vigorous and very vigorous activities, and numbers of daily steps. Additionally, the International Physical Activity Questionnaire (IPAQ) long version, validated and adapted for the elderly Brazilian population (Mazo et al., 2010; Benedetti et al., 2007), will be applied on the first home visit . The instrument assesses energy expenditure in METs/min/week for walking, moderate, vigorous and sedentary activities. | — |

| Physical and functional fitness will be assessed through strength tests of upper and lower limbs. The strength of the upper limbs will be assessed using a handgrip dynamometer, with a measurement scale ranging from 0 to 100 kilograms force (kgf). The test will be performed with the elderly in a seated position, with the shoulder slightly adducted, the elbow flexed at 90 ° and forearm and wrist in neutral position. Three maximum gripping movements will be performed, with a one-minute recovery interval, using the average of the three attempts (FERNANDES; MARINS, 2011). The strength of the lower limbs will be assessed using the chair lift and sit test. The test will begin with the volunteer in a seated position, with arms crossed over the trunk and, at the sign of the evaluator, should get up and sit in the chair as quickly as possible, five times. If the participant is unable to get up 5 times or complete the test in more than 60 seconds, 0 points are awarded; if the test time is 16.7 sec or more, 1 point is assigned; if the test time is from 13.7 to 16.69 sec, 2 points are awarded; if the test time is 11.2 to 13.69 sec, 3 points are awarded; and finally, test time less than 11.19 sec: 4 points (GURALNIK; et al., 1994). Mobility and dynamic balance will be assessed using the te ste Timed Up and Go (TUG), which consists of getting up from a chair, walking at the usual speed on a 3 meter linear path, returning and sitting down (BOHANNON, 2006).;The mental and cognitive status of the elderly will be assessed using the Montreal Cognitive Assessment, in its translated and validated version for the elderly Brazilian population (MoCA-BR) (SARMENTO, 2009; MEMÓRIA, et al., 2012), whose score ranges from 0 at 30 points, with a higher score indicating better cognitive function. The cut-off point for detecting cognitive impairment is 26 points and, if the individual has less than 12 years of schooling, a point is added to the total score (MEMÓRIA et al., 2012).;The quality of l | — |
