Chair-based exercise programs in institutionalized older women: Salivary steroid hormones, disabilities and frailty changes.

Abstract Purpose Many people experience aging-related losses in different physical domains, which leads to a condition often called physical frailty (PF). The aim of this study was to analyse the effects of two different, 28-weeks, class chair-exercise protocols on salivary steroid hormones (SH), PF, and functional disabilities (FD) in frail older women. Methods A sample of older frail individuals (n = 60, 817.84 years) participated in the study and were divided into three groups: chair elastic-band muscle strength exercises (CSE), n = 20), chair-multimodal exercise (CME, n = 21) and a control non-exercise group (CGne, n = 19). Both exercise programs consisted of 45 min of supervised chair-…
