Abstract

Bodybuilding is a physical exercise closely linked to the work of a fundamental physical quality to daily living activities: the strength. Among the activities, even the simplest like a task of maintaining the balance, it’s influenced by the strength, mainly the lower limbs strength, directly responsible to recovery the centre of gravity’s sway. The purpose of this study is to asses the influence of strength training on older adults’ balance. Five individuals more than sixty years old participated in this study. To asses strength was used repetitions maximum test with submaximal load. To asses balance was used a force platform, with frequency acquisition of 100Hz and 30 seconds of collection time, in opened eyes and closed eyes trials. Training was executed during 12 weeks in the frequency of twice weekly and works the body globally, evolving with the load progression and alteration of the intensity and volume variables in according with a schedule provided to each week. The results show that most individuals preserve or increase the strength levels with the training, as well as improve the body composition levels. However, to the balance there isn’t an evolution standard in any balance variables and some individuals even worse yours scores in some variables, suggesting that the training wasn’t effective to improve elderly balance.
