Abstract

Akio Tada Faculty of Health Science, Hyogo University, Kakogawa, Hyogo, Japan Background: In recent years, there have been an increasing number of older adults who suffer from mental disorders globally.Objective: The objective of this study was to examine the effect of an intervention that consisted of an exercise program to improve the mental health of community-dwelling older adults.Participants and methods: The recruited participants of this study were community-dwelling older adults aged ≥60 years who participated in a comprehensive health promotion program in Kakogawa, Japan. Participants in the intervention group received an exercise program that was developed for older adults using Thera-Band. To measure participants’ mental health status, a Japanese version of the short form of the Profile of Mood States (POMS-SF) was used. Stress markers were measured, such as salivary cortisol, alpha-amylase, and sIgA levels. All participants provided salivary samples and completed psychological questionnaires at baseline and 6-month follow-up.Results: No significant differences were observed between the intervention and control groups with respect to POMS-SF score and salivary biomarker profile at baseline. After the intervention, the intervention group showed a significant decrease in the POMS-SF “fatigue” score and cortisol level. No significant changes were observed in the control group.Conclusion: Simultaneous changes in feelings of fatigue and cortisol levels were observed among subjects who had received the intervention of regular exercise. Further research is needed to investigate the effectiveness of exercise intervention in improving mental health among older adults.
