Abstract

Introduction: A number of body modifications accompanies aging, for instance, reduction in muscle performance, balance and flexibility. Physical exercise, as well as anti-inflammatory nutrients, can proportionate benefits in the preservation of physical abilities. In this study, we hypothesize that supplementation with ômega-3 fatty acid could have an additional effect on a flexibility exercise program in elderly. Aim: To evaluate the effects of ômega-3 on flexibility and articular mobility in elderly submitted to a flexibility-training program. Methods: this is a double blind randomized study with a non-probabilistic sample. Twenty-one participants, submitted to a 12 weeks flexibility exercises program, were distributed in two groups, receiving an ômega-3 supplement (PAS), or placebo (PAP). At the beginning and at the end of the experiment, the participants were evaluated for anthropometric measures (body mass and height -to calculate body mass index -and waist circumference), and flexibility measures (movements of lateral flexion of the cervical spine, shoulder flexion, hip flexion, dorsiflexion and plantar flexion). Results: when compared the beginning and the end of the study, both groups showed significant differences in some movements. To PAP, the differences were: right cervical (8%), shoulder (10%) and dorsi flexion by left ankle (22%); to PAS, the differences were shoulder movement to right (8%) and left (11%) sides and planti flexion by right ankle (19%). However, the ômega-3 supplementation was not enough to promote additional effects on any of the investigated variables. Conclusion: The present lead us to conclude that stretching physical activities seem to be beneficial for the elderly. However, our results did not show any additional benefits with the use of ômega-3 supplementation.
