There is a lack of knowledge about the influence of individual physical activities on the quality of life (QoL) of
older adults, especially in strength training and swimming, two popular activities.
Objectives: to assess and compare the perceived QoL levels among sedentary, swimming and strength training groups in
Methods: Twenty one subjects were evaluated: 9 sedentary, 10 swimming and 12 strength training. Physical activity levels
were assessed by the International Physical Activity Questionnaire short version, and the physical, psychological, social
and environmental domains, as well the general QoL of each group, were assessed through the World Health Organization
questionnaire short version. In addition, the contribution of each domain in general QoL was also verified.
Results: The sedentary group presented a statistically lower score in each variable examined (p<0.05). The physical
domain was higher only in the strength training group and the psychological and social domains were higher only in the
swimming group. In relation to the influence on general QoL, the physical domain (i.e., sedentary); the physical and
psychological domains (i.e., swimming) and the social and environmental domains (i.e., strength training) were
Conclusion: The results suggest that the QoL levels were always lower in the sedentary group. However, the
determination of the domain depended on the physical activity level of each subject. Further, the domains with better
scores were not necessarily the ones that showed a higher association with the general QoL in each group.
