This study evaluates the adaptations on the functional capacity and cardiovascular in elderly after a physical activity program circuit training. The participants were divided into three groups: Circuit training based on high-intensity interval training group (HIICT), Circuit training at moderate intensity group (MICT) and Control group (CG).
Three groups of participants (circuit training based on high-intensity interval training, circuit training at moderate intensity and not training group) will enter the study. The intervention will consist of a physical exercise program in day centers. Intensity progression will be encouraged according to the rate of perceived exertion. Progression of exertion will be "very hard", "extremely hard" and "maximal exertion" for HIT group, and "light", "somewhat hard" and "hard" for group. Assessment will be undertaken at two-time points: baseline and after 16 weeks of exercise training. Assessment will include VO2 peak, functional capacity, health-related quality of life, cognitive state and daily physical activity.

Analyses changes in maximum oxygen consumption (VO2max).
A modified Balke treadmill protocol will be used to estimate aerobic capacity (VO2max).
Time frame: Pre and post after sixteen weeks of intervention
Analyses changes in maximum oxygen consumption (VO2max).
VO2max was assessed using the 6-Minute Walk Test. The participant should walk the longest distance possible in 6 minutes by walking continuously the 42 metres indicated on the floor. It measures the distance in meters
Time frame: Pre and post after sixteen weeks of intervention

Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in body mass index (BMI).
BMI was assessed using bioimpedance analysis (OMROM BF-306).
Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in gait.
Gait was assessed using the Timed Up and Go Test. To stand up from a standard arms chair, walk 3 meters, turn back the cone walk back and sit down to the chair. The time in seconds is record.
Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in balance.
Balance was assessed using the One Leg Standing Test. This test consist in maintain one leg stance for as long as possible. The test was considered normal if the one leg standing time reached 30 seconds.
Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in lower body strength.
Lower body strength was assessed using the Sit To Stand 30. For the Sit To Stand 30, the participant consist in measures how many repetition the participant can to stand up and sit down during 30 seconds.
Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in upper body strength.
Upper body strength was assessed using the Arm Curl Test (30). For this test, the participant consist in measures how many repetition the participant can to curl up and curl down during 30 seconds.
Time frame: Pre and post after sixteen weeks of intervention.
Analyses changes in maximal handgrip strength.
To measure the amount of strength developed by each hand in kg.
Time frame: Pre and post after sixteen weeks of intervention.
