Sponsored by National Cheng-Kung University Hospital · Not applicable, Interventional, and Other
Subjects are divided into two groups, (1) Control (Ctrl) and (2) Smart Exercise (SE) group. Participants in the Ctrl group are instructed to perform resistance band training twice weekly according to a paper-based exercise guide, whereas participants in the SE group are instructed to perform resistance band training twice weekly for 12 weeks using the Resistance Band Training System. The physical fitness tests and questionnaire of both groups are performed before and after the 12-week exercise program.
Participants are divided into two groups: (1) the control (Ctrl) group and (2) the Smart Exercise (SE) group. Participants in both groups are instructed to perform resistance band training twice weekly for 12 weeks, with each session lasting approximately 30 minutes.
Participants in the Ctrl group perform resistance band training according to a paper-based exercise guide. Training completion is recorded by the participants using a paper checklist after each training session. The completed checklists are collected and reviewed by the research team at the end of the study to verify adherence to the prescribed exercise program.
Participants in the SE group perform resistance band training using the Resistance Band Training System. Training sessions and exercise completion are recorded by the system.
Physical fitness tests and questionnaires are administered to participants in both groups before and after the 12-week exercise program. Changes in physical fitness and questionnaire outcomes are evaluated between the two groups.
National Cheng-Kung University Hospital is the lead sponsor of 277 studies on the registry; 70 are open to participants now.

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).
