Abstract

Aging is a phenomenon that can be assumed of the natural course of human life.During aging, some changes in all organs that led to increase impairment in balance meanwhile the circadian cycle also isn’t ineffective. The aim of this study was to detective the effect of a balance training program in the morning and afternoon on static and dynamic balance in healthy elderly. This quasi-experimental study in 24 healthy elderly subjects with no history of regular exercise (5.5 ± 68.7 years old, height 8.2 ± 1.6 m, weight 8.9 ± 68.4 kg) were selected as available. The subjects were randomly divided into two groups of 12 each divided into morning and afternoongroups were subjected to 8 weeks of balance training.  To assess dynamic balance used the stars test and statistical calculations were performed using SPSS version 20. Comparisons between groups based on the pre-test and post-test  ​​for the overall dynamic balance, the effect of exercise on balance provided in the morning and afternoon. It is not seen the improvement in the star test after a period of exercise training, between two groups (p >0.05). The results of the two groups showed improved balance training, after the training. Comparisons between groups based on the pre-test and post-test values ​​for the general dynamic balance, the effect of exercise on balance provided in the morning and afternoon. It can be seen that after a period of exercise training improved the dynamic balance test star general in the internal anterior, internal, posterior, external posterior and external is not in any of the two groups (p>0.05), and in anterior and external anterior Afternoon practice is a good time (p<0.05). According to this study, balance training in the morning rather than in the afternoon, except for the South and South West of dynamic balance was not significantly different between people, so special time to do some exercises to improve balance and dynamic balance in the elderly is not recommended.
