- Abstract
Introduction: Middle-aged women are influenced by mood symptoms such as anxiety which may be associated with autonomic modulation.1 Stretching improves mood symptoms and increases parasympathetic activity. However, there are no reports that examine these indicators simultaneously.2,3 Objective: To investigate the acute effects of stretching on mood symptoms and autonomic modulation in middle-aged women. Methods: Twenty-five middle-aged women (age: 51.8 ± 4.4 years) enrolled in this study. Each participant completed two conditions (static stretching and control) for 25 minutes each on separate days in a random order. Static stretching was conducted with a whole-body program. The mood symptoms were measured using the State Trait Anxiety Inventory (STAI) questionnaire. Total score, subscales of anxiety-present and anxiety-absent were calculated pre- and post-intervention. Autonomic modulation was measured by heart rate variability (HRV). The HRV indices which assess parasympathetic activity were calculated with the root mean square of successive differences (RMSSD) and high-frequency power (HF) pre- and post-intervention and again 30 minutes later (PRE, POST-0, POST-30). The RMSSD and HF were transformed using the natural logarithm. Two-way repeated-measures analysis of variance was performed, and the Bonferroni test was used for posthoc comparisons. Results: In the stretching condition, mood symptoms, especially state anxiety indicated with STAI-total (PRE: 34.2 ± 7.7; POST-0: 29.6 ± 6.7, p = < 0.001) and positive mood state determined with STAI-anxiety absent (PRE: 22.5 ± 6.9; POST0: 19.1 ± 6.3, p = < 0.001) were significantly improved after stretching. However, there were no significant changes with RMSSD and HF with either POST-0 or POST-30 in both stretching and control condition (p = 0.068-0.808). Conclusion: Stretching immediately improved mood symptoms in middle-aged women. However, autonomic modulations were unchanged after stretching. Therefore, stretching is an effective intervention for mood symptoms in middle-aged women.
