The CONTROL group did not exercise.

The XBOX group performed exercise for 60 min, three times/week, for 6 weeks, using the Xbox Kinect game "Your Shape Fitness evolved". This game was chosen because it simulates an environment with a variety of physical activities, in which the majority can be practiced by older adults. The activities were carried out individually. The game activities selected for the physical activity sessions were: 1) Zen-Develop it (stretching, balance and flexibility activities, similar to Yoga); 2) Pump it (to fill balls until they burst); 3) Wall Breaker (to break blocks, similar to boxing); 4) Kick it (soccer activity); 5) Hurricane (to lift the balls off the floor and not let them fall); 6) Stack in Up (balance activity).
