Experimental: Intervention Group
Behavioral: Physical Activity
The intervention consisted of elderly-specific physical activity program for one year. During this period a total of 123 physical activity sessions were carried out. Each session lasted 50 minutes and included stretching, aerobic endurance exercises, resistance exercises, activities involving coordination, agility and flexibility, respiratory exercises and relaxation exercises. The sessions took place three times a week, according to American College of Sports Medicine (ACSM) recommendations. Workloads were adjusted for each subject bimonthly according to their capacity. The sessions were standardized and carried out by previously trained physical educators.

- Static Balance [ Time Frame: one year ]The one-leg stance test (OLST) was used to evaluate static balance. A point was marked at eye level on a board approximately one meter from the volunteer. Focusing on this point, the volunteer, with arms akimbo, lifted the leg of his or her choice by flexing the knee. The performance was timed with a chronometer (precision: 1ms) until either the individual lost balance or 30s was reached. The test was then carried out with the opposite leg and the series was repeated until three trials per leg had been performed. The mean time of the three trials was used for analysis.
- Aerobic Endurance [ Time Frame: one year ]Aerobic endurance was measured using the one-mile test or the Rockport Walking Test, which consists of having subjects walk 1,609 meters quickly, but without running. The time spent performing the task and the final heart rate were measured.
- Dynamic Balance [ Time Frame: one year ]A maximum-speed walking test (MSWT) was used to measure dynamic balance. A course 3.33 m long and 33.3 cm wide was marked on the floor with tape and, beginning from a standing position, the participant walked the entire course as fast as possible without running when the signal was given. Three trials were carried out; the chronometer (precision: 1ms) was started as soon as the subject's foot crossed the starting line. The mean time from the trials was used for analysis.
- Flexibility [ Time Frame: one year ]A sit-and-reach test (SRT) with a modified Wells flexometer (precision: 1mm) was used to evaluate the flexibility of the trunk and upper limbs. The subjects sat on the floor with their soles flush against the lower edge of the device. Then, with their overlapped hands on the upper surface touching a sliding position marker, they pushed it forward along the scale while exhaling. The best of three trials was considered the result.
- Handgrip Strength [ Time Frame: one year ]Handgrip Strength was measured with a Jamar® hydraulic hand dynamometer (Sammons Preston Roylan, Bolingbrook, IL, USA) featuring a grading scale of 0-100 Kgf (precision: 2 Kgf). The best of three trials with the dominant upper limb was selected for analysis.
- Body Mass Index [ Time Frame: one year ]The weight and height were measured with a calibrated analogue scale with a stadiometer. The variable of weight was measured three times and the mean value considered. Such variables were used to calculate the BMI of the volunteers.
- Body weight [ Time Frame: one year ]The weight was measured with a calibrated analogue scale with a stadiometer. The variable was measured three times and the mean value considered.
