This study was aimed to examine the effects of participation in a 12-week multicomponent exercise program on frailty, cognitive function, and sleep quality among older adults. The primary research questions of this study are as follows: 1. Is a multicomponent exercise program effective in reducing frailty levels in older adults? 2. Is a multicomponent exercise program effective in improving cognitive functions (memory, attention, and executive functions) in older adults? 3. Is a multicomponent exercise program effective in improving sleep quality in older adults? The study hypothesizes that participation in a multicomponent exercise program will lead to a reduction in frailty levels, improvement in cognitive functions, and enhancement of sleep quality among older adults. Researchers were compared the multicomponent exercise program to a control group (no intervention) to see if the multicomponent exercise program works on frailty, cognitive function, and sleep quality among older adults. Intervention group participants were: \- attended the multicomponent exercise program, 12-week period, with sessions held twice weekly, each lasting 45-60 minutes, in groups of 6-8 participants at a municipally affiliated healthy living center under nurse supervision.
The study was conducted with elderly individuals aged 65 and over enrolled in a municipal wellness centre meeting the inclusion-exclusion criteria. A total of 110 elderly individuals were included in the study. These individuals were randomly assigned to two groups: intervention and control groups. Pre-test data were collected November 2025 in a quiet room at the wellness centre by outcome assessors from both the intervention and control groups using the "Personal Information Form", "Edmonton Frail Scale (EFS)", "Mini Mental State Examination (MMSE)" and "Pittsburgh Sleep Quality Index (PSQI)" on a self-report basis. The Multicomponent Exercise Program was administered to the intervention group for 12 weeks, twice a week, in groups of 6-8 people, in sessions lasting 45-60 minutes each, under nurse supervision. At the end of the Multicomponent Exercise Program, both the intervention and control groups were administered the "Edmonton Frail Scale (EFS)", "Mini Mental State Examination (MMSE)" and "Pittsburgh Sleep Quality Index (PSQI)" as a post-test between January and February 2026. The control group received no intervention during the 12-week program; individuals continued with their daily living activities.

The program is conducted twice a week for 12 weeks, in sessions lasting 45-60 minutes each, at a municipal health center, in groups of 6-8 people, and under the supervision of a nurse. Each exercise session consists of four phases: warm-up, aerobic exercise, strength and balance training, and cool-down. The warm-up phase includes light-paced walking and range of motion exercises; the aerobic phase involves moderate-intensity walking and rhythmic movements; the strength and balance exercise phase uses resistance bands and light weights to target upper and lower extremity muscle groups; and exercises aimed at improving postural stability through functional activities such as sit-to-stand, single-leg standing, and tandem walking. The cool-down phase includes static stretching exercises, breathing exercises, and relaxation techniques.

Frailty total mean score
Frailty was assessed using the Edmonton Frail Scale (EFS), a multidimensional instrument comprising nine domains that evaluate frailty in older adults. Total scores range from 0 to 17, with higher scores indicating increased frailty.
Time frame: From enrollment to the end of the multicomponent exercise program at 12 weeks
Cognitive function total mean score
Cognitive function was measured using the Mini-Mental State Examination (MMSE), which evaluates orientation, registration, attention and calculation, recall, and language skills. Scores range from 0 to 30, with higher scores reflecting better cognitive performance
Time frame: From enrollment to the end of the multicomponent exercise program at 12 weeks
Sleep quality total mean score
Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), which consists of seven components evaluating sleep quality over the past month. Higher total scores indicate poorer sleep quality
Time frame: From enrollment to the end of the multicomponent exercise program at 12 weeks.
