Brief summary
This study will examine functional and physiological responses to a 12-week multicomponent exercise program in community-dwelling older adults. Adults aged 60 to 81 years will be randomly assigned to either a multicomponent exercise group or a control group. The supervised exercise program will be performed twice weekly for 12 weeks and will include aerobic walking, resistance exercises, balance and agility training, flexibility exercises, and cool-down activities. Functional performance will be assessed using the six-minute walk test, the 30-second chair stand test, and the 8-Foot Up and Go test at baseline and after 12 weeks. Resting cardiac autonomic function will be assessed using heart rate variability. In addition, an exploratory responder-non-responder analysis will be conducted to examine whether baseline heart rate variability is associated with individual functional adaptations following the exercise program. This study may help identify physiological markers related to functional responsiveness to exercise in older adults.
Interventions
Participants in the exercise group will complete a supervised multicomponent exercise program twice weekly for 12 weeks. Each session will last approximately 45 to 50 minutes and include warm-up, aerobic interval walking, resistance exercises, balance and agility training, flexibility exercises, and cool-down activities. Exercise intensity will be monitored using the Borg Rating of Perceived Exertion scale and exercise difficulty will be progressively increased by increasing repetitions, walking duration, walking pace, and task complexity.

Intervention model description
Participants are assigned to either a 12-week supervised multicomponent exercise group or a control group. Outcomes are assessed at baseline and after the 12-week intervention period.
Eligibility
Inclusion criteria
* being 60 years of age or older, * being able to walk independently, * not having any serious cardiovascular, neurological, or musculoskeletal disease that would prevent exercise. * do not use medications that may affect autonomic nervous system function
Exclusion criteria
* diagnosed cardiac arrhythmia, * uncontrolled hypertension, * use of medications that may affect autonomic nervous system function, * inability to perform functional performance tests.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in six-minute walk distance | Baseline and 12 weeks | Functional walking capacity will be assessed using the six-minute walk test. The total distance walked in six minutes will be recorded in meters at baseline and after the 12-week intervention. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in 30-second chair stand test performance | Baseline and after 12 weeks | Lower-limb functional strength will be assessed using the 30-second chair stand test at baseline and after the 12-week intervention. |
| Change in 8-foot Up-and-Go test performance | baseline and after 12 weeks | Functional mobility and agility will be assessed using the 8-Foot Up-and-Go test at baseline and after the 12-week intervention. |
