Brief summary
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).
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analyses changes in maximum oxygen consumption (VO2max). | Pre and post after sixteen weeks of intervention | A modified Balke treadmill protocol will be used to estimate aerobic capacity (VO2max). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Analyses changes in heart rate reached in ergometry. | Pre and post after sixteen weeks of intervention | Analyses during modified Balke treadmill protocol |
| Analyses changes in blood pressure reached in ergometry. | Pre and post after sixteen weeks of intervention | Analyses during modified Balke treadmill protocol |
| Analyses changes in maximum speed reached in ergometry. | Pre and post after sixteen weeks of intervention | Analyses during modified Balke treadmill protocol |
| Analyses changes in duration test reached in ergometry. | Pre and post after sixteen weeks of intervention | Analyses during modified Balke treadmill protocol |
| Analyses changes in fat percentage. | Pre and post after sixteen weeks of intervention. | Fat percentage (%) was assessed using bioimpedance analysis (OMROM BF-306). |
| Analyses changes in body mass index (BMI). | Pre and post after sixteen weeks of intervention. | BMI was assessed using bioimpedance analysis (OMROM BF-306). |
| Analyses changes in gait. | Pre and post after sixteen weeks of intervention. | 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. |
| Analyses changes in balance. | Pre and post after sixteen weeks of intervention. | 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. |
| Analyses changes in lower body strength. | Pre and post after sixteen weeks of intervention. | 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. |
| Analyses changes in upper body strength. | Pre and post after sixteen weeks of intervention. | 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. |
| Analyses changes in maximal handgrip strength. | Pre and post after sixteen weeks of intervention. | To measure the amount of strength developed by each hand in kg. |

| Measure | Time frame | Description |

| Analyses change in Self Assessed Physical Activity. | Pre and post after sixteen weeks of intervention. | Physical activity was assessed using the Physical Activity Scale of the Elderly (PASE) questionnaire. The PASE is designed to assess physical activity in older persons. The total PASE score was computed by multiplying the amount of time spent in each activity (hours/week) or participation (yes/no) in an activity by empirically derived item weights and summing over all activities. PASE scores for this study ranged from 0 to 756 with higher scores indicating more physical activity. |
