Subjects are divided into two groups, (1) Control (Ctrl) and (2) Smart Exercise (SE) group. Ctrl group are instructed to maintain their daily life. SE participants are instructed to do exercise with smart exercise system twice per week for 12 weeks. The physical fitness tests and questionnaire of both group are performed before and after the 12-week exercise program.
The smart exercise system contain an upper extremity cycle ergometer (UEE) and a lower extremity cycle ergometer (LEE). SE group are instructed to do once session of UEE and once session of LEE per week, 30 minute per session, lasting for 12 weeks. Before each exercise, the physiological parameter are measured to ensure safety. During exercise, heart rate of user and revolutions per minute (RPM) of the ergometer is detected per second. After each session of exercise, the rating of perceived exertion (RPE) of user is also inquired and recorded.

The smart exercise system contains an upper extremity ergometer (UEE) and a lower extremity ergometer (LEE). The revolutions per minute (RPM) of the ergometer are instructed to maintain in 55-65. The resistance of UEE is set from level 1 at the first session, and adjusted by rating of perceived exertion (RPE) of each user after each end of the session. The resistance of LEE is set from level 2 at the first session, and adjusted by rating of perceived exertion (RPE) of each user after each end of the session.

SARC-F
The SARC-F questionnaire is a Fast diagnostic test for SARCopenia. The questionnaire contains five items, which are Strength, Assistance in walking, Rise from a chair, Climb stairs, and Falls. The scores range from 0 to 10, with 0 to 2 points for each component. Score equal to or greater than 4 is predictive of sarcopenia and poor outcomes.

EQ-5D (EuroQol- 5 Dimensions)
EQ-5D is a standardized instrument with 5-item questionnaire for measuring generic health status. EQ-5D was first introduced in 1990 by the EuroQol Group. In which health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Rated level can be coded as a number 1, 2, or 3, which indicates having no problems for 1, having some problems for 2, and having extreme problems for 3. As a result, a person's health status can be defined by a 5-digit number, ranging from 11111 (having no problems in all dimensions) to 33333 (having extreme problems in all dimensions).
