Examining the Impact of 28-Week Multicomponent and Strength Exercises on Brain Health, Salivary Stress, and Mental Well-Being in Frail Older Women: A Controlled Trial analysis.

Background: In recent years, the efficacy of various physical exercise programs in enhancing functional fitness among frail older adults has gained recognition. However, limited research has concurrently explored the long-term effects of exercise on brain health, stress biomarkers, and mental well-being. This study aimed to investigate the impact of two distinct chair-based exercise programs on salivary stress hormones and psychological well-being in frail older women over a 28-week period.
