The exergame group will receive exergame training for 12 weeks, 2 times a week and 60 min per session.

The control group will not receive any intervention and maintain their lifestyle for 12 weeks.

The one-to-one supervised training session consists of 10 min warm-up exercise, 40 min interactive exergame, and 10 min cool-down exercise. Both physical (muscle strength, coordination and balance in lower limbs) and cognitive functions (visuospatial, attention, short-term memory, calculation, reaction and executive function) will be trained through the interactive exergame.

Dominant hand grip (kg) will measured by a dynamometer. Participants will stand with their arms down by their sides. They will squeeze the dynamometer with maximum isometric effort, which is maintained for 6 seconds.

Female less than 18 kg and man less than 28 kg indicate weakness in grip strength.

Lower limbs strength will be assessed by the Five Times Sit to Stand. Participants will be asked to sit on the chair with arms folded across their chest, and stand up and sit down as quickly as possible for 5 times. The time (s) to complete the task will be recorded.The time more than 12 seconds indicates weakness in lower limbs strength.

Appendicular muscle mass will be assessed by the Body Impedance Analysis (BIA).Participants will be asked to stand on the machine and hold the handle of the machine. Female less than 5.7kg/m2 and male less than 7 kg/m2 indicate lower muscle mass.

Function ability test will be determined by the timed up and go test (TUG). Participants will be asked to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. The times(s) to complete the task will be recorded. Higher than 12s indicate weakness in function ability.

Static balance test will be assessed by the modified Clinical Test for Sensory Interaction in Balance(mCTSIB), The mCTSIB was developed as a clinical version of the Sensory Organization Test and was developed to assesses sensory contributions to postural control.

Participants will stand with their hands at their sides, feet together and perform the following 4 sensory conditions: (1) Stand on firm surface with eyes open (2) Stand on firm surface with eyes closed (3) Stand on foam surface with eyes open (4) Stand on foam surface with eyes closed. Each condition will be timed for maximum 30 seconds. The test is terminated when a participant's arms or feet moves. If participants are unable to maintain the position for 30 seconds, they are then provided with 2 additional attempts. The time (s) to complete each condition will be recorded.If they can't complete this test indicate weakness in static balance

Physical Activity will be examined by the International Physical Activity Questionnaire (IPAQ)-Short Form. Participants will be asked about their duration (in minutes) and frequency (days) when performing four specific types of activity: walking, moderate intensity, vigorous intensity and sitting. Female less than 270 kcal and male less than 383 kcal indicate low physical activity.

Sarcopenia will be screened by the SARC-F questionnaire including strength, assistant in walking, rise from a chair, climb stair and fall. The answer is not difficult with 0 point, a little difficult with 1 point and very difficult with 2 points.The score is total score is between 0 and 10. The score more than 4 indicates high risk of sarcopenia.
