About this trial
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.

Treatments tested in this trial
smart exercise system
DeviceThe 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. The system also continuously records exercise-related device data, personal physiological parameters, and facial action units in a structured and systematic manner.

SMI
Skeletal muscle mass index (SMI), which is the sum of the muscle masses of the four limbs as appendicular skeletal mass (ASM) in kilograms divided by the square of height in meters, is detected by bioelectrical impedance analysis.
