objective: The aim of this research to find out whether physical activity (PA) affects the quality of life (QoL) of seniors living in retirement homes. design: Prospective study. Participants: The study group consisted of 47 seniors. The average age was 80.09 years of age (SD±6.10). The group included mobile and independent seniors capable of independent activity. The research was carried out in a retirement home in Sabinov. methods: The seniors performed the activity program in the outdoor and indoor areas of the facility. We evaluated the QoL before and after the intervention (WHOQOL-BREF and WHOQOL–OLD). PA was measured using accelerometer ActiGraph GT3X+. The intervention lasted 12 weeks. results: The results point to improved parameters, namely: calories and sitting. An improvement could also be seen in mild and moderate physical activity (p<0.05). QoL was confirmed only in the following domains: Psychological and Health satisfaction (p<0.05). conclusion: Although the evaluation of the overall QoL of seniors as a result of the activity program had negative results, we can conclude that physical activity is very important and we should not let seniors do nothing in a latent state.
