Aging refers to the time sequential detoriation that occurs in most animals including weakness, increased susceptibility to disease and adverse environment conditions, loss of mobility and agility and age related physiological changes.Balance and muscle force deteriorate with aging, and it has been suggested that a decrease in the ability to generate force in the lower extremity muscles contributes to balance impairment. balance impairments are also associated with poorer mobility measures in elderly population. Sample A group of 24 elderly subjects of age between 60­80 years were included in the study. Subjects are divided into two groups 12 in each group (Group A no. = 12), (Group B no. = 12). Group A (Lower limb muscle strength training) Group B (Trunk muscle strength training was given. Conclusion: Based on the result of present study, it can be concluded that there is no significant change in lower limb and trunk muscle strength training on balance in elderly population. Thus, the null hypothesis, that there is no difference in lower limb and trunk muscle strength training on balance in elderly population holds true.
