Indonesia is recently facing major age-related issues as the elderly population continues to grow. As such, aging will soon become a policy concern that will require attention from the government. To ensure that the elderly receive adequate support during their old age, recently several new laws have been passed . One of the main consequences of this is that quality of life (QOL) issues will become increasingly significant. That way, Andrews  noted that it will require greater efforts in terms of health promotion and disease prevention in old age to ensuring the health and well-being of the growing numbers and proportion of older people. Even though high morbidity and mortality rates and low education and socio-economics levels in general have an effect, activity has been shown to be beneficial to maintaining the health status of the elderly and also has been valuable in maintaining quality of life when faced with several health problems . Quality of life is a difficult and complex idea to state and distinguish in a uniform way. Addressing these conceptual issues and the ensuing challenges of assessing quality of life is essential in the context of long-term care and support for older adults .
Quality of life, Gabriel and Bowling  stated a social relationships, psychological wellbeing, activities, health and functional ability, and social roles were the consistently emphasized central planks. It is guided that the quality of life revealed both macro-societal and socio-demographic influences on people and the personal characteristics and concerns of individuals. The other mentioned about QOL that it was as a conscious cognitive opinion of satisfaction in life and can be measured with the Satisfaction with Life Scale (SWLS) . QOL of older people in Indonesia is still low, and it more related to having a low education and socio-economic level . The prevalence of physical activity in Indonesia is also below from median score of MET-minute per day of physical activity . However, a few studies in Indonesia have addressed the association between physical activity and quality of life in elderly.
Archer and Blair  suggested that physical activity and chronic diseases demonstrate a strong inverse relationship. So that was irrefutable of the health benefits and effect of physical activity. However, in other study has revealed that an exercise program designed may also have a positive effect on several cardiovascular risk factors through weight-bearing skeleton exercise [15, 16]. The relationship between physical activity and QOL changes has been undertaken previously. Both clinical setting and community-based intervention of QOL changes has been studied. McAuley et al.  mentioned the elderly who more active had greater self-efficacy, which was related with more positive physical and mental health status. Authors suggested health statuses become more positive relation to satisfaction with life. In that case self-efficacy as role of instrumental in these relationships. Another study focused the group with higher physical activity levels had higher values in all of the domains of HRQOL . We believe previous studies have only dealt with the situation in developed countries, whereas present study focuses on the situation in developing country.
As such an investigation of physically active elderly subjects may allow the association physical activity and QOL to be determined. We suppose that this is the observational prospective study to appraise the link between physical activity and quality of life of the elderly living in the community in Indonesia. In light of above this study aim was to examined involvement physical activity program and QOL domains of the healthy elderly. The main objectives of this study was to determine whether the hypothesized achieved of physical activity is consistent with higher enhancement of physical, psychological, social relationships, and environmental. It was hypothesized that those elderly who engaged at the physical activity program would experience higher improvement of quality of life than those who were not.
