This study evaluates the effects of exercise intervention on muscle strength and walking speed for the community-dwelling elderly. Half of the participants will receive exercise training, while the other half will maintain their usual activities of daily living.
Physical inactivity can result in physical frailty and sarcopenia. Physical frailty and sarcopenia are two common and mostly overlapping geriatric conditions, which may cause negative consequences of aging, such as disability, hospitalization and mortality. Regular physical activity has been suggested to maintain or improve functional capacity and body composition, as well as delay aging process. Nevertheless, inactivity prevalence still significantly increases among older adults, especially those with a disability. One of the probable reasons is that the use of physical activities or exercise interventions is not tailored to the needs and capabilities of the elderly.

SINGLE
Enrollment
60
Aerobic exercises, strengthening exercises, flexibility training for 60min, twice a week for 12 weeks
Walking speed
Participants are asked to walk along a 14 m hallway. The time taken to the middle 10 m is recorded to calculate walking speed (m/s).
Time frame: Change from baseline at 12 weeks
Muscle strength
Muscle strength is assessed using hand-hold Dynamometers
Time frame: Change from baseline at 12 weeks
Timed up and go test
Participants are asked to stand up, walk 3 m, turn around a cone, and return to a sitting position
Time frame: Change from baseline at 12 weeks
Walking endurance
Participants are asked to walk back and forth along a 20-meter corridor and to cover the maximum distance possible in six minutes
Time frame: Change from baseline at 12 weeks
Sit-to-stand test
Participants are asked to stand up and sit down 5 times.
Time frame: Change from baseline at 12 weeks
Berg balance scale
It consists of 14 items, including sitting unsupported, standing unsupported, standing with eyes closed, standing with feet together, standing on one foot, turning to look behind, retrieving objective from floor, random standing, reaching forward with an outsrptretched arm, sit to stand, stand to sit, transfer, turning 360 degrees, stool stepping, scored from 0 to 4, "0" indicates the lowest level of function and "4" the highest level of function. Total Score = 56.
Time frame: Change from baseline at 12 weeks
Gait kinematics
Gait kinematics are assessed by angular displacement of lower limbs using shoe-worn inertial measurement unit based device
