Effectiveness of VR Exercise Intervention on Functional Fitness and Quality of Life Among Elderly

Senior Fitness Tests were to evaluate the functional fitness of older adults. The test has six items: back scratch (cm), chair sit-and-reach (cm), arm curl, chair stand (times), 2-minute step (times), and 8-foot starting distance (sec). The functional fitness (e.g., back scratch, chair-and-reach, arm curl, chair stand, 2-minute step) of higher scores means better functional fitness.

The functional fitness (e.g., 8-foot starting distance) of higher scores means poorer functional fitness.

This study is a measure to assess change between two-time points.

(1)Change in functional fitness of older adults from 1-week baseline (pre-test) to 12 weeks (i.e., exercise intervention phase). (2) Discontinuation of exercise intervention at 13 (post-test) to 24 weeks (follow-up) and ongoing follow-up of older people's function fitness maintenance outcomes.

The WHOQOL-OLD is used to measure the quality of life of older adults. This questionnaire is comprised of 24 items divided into six domains, with each domain having four items. These domains include sensory abilities, autonomy, response to the past present, and future activities, social participation, response to death and dying, and response to intimacy. Responses were rated on a Likert scale, with a 1-5-point scale for each item. The result with the highest total score indicates a greater quality of life.

This study is a measure to assess changes between two-time points.

(1) Change in self-perceived quality of life from 1-week baseline (pre-test) to 12 weeks (i.e., exercise intervention phase). (2) Discontinuation of exercise intervention at 13 (post-test) to 24 weeks (follow-up) and ongoing follow-up of older people's self-perceived quality of life maintenance outcomes.

Measure older adults of height by attaching cloth ruler tape to the wall (units of measurement: cm). The weight of the elderly is measured using commercially available electronic weighing machines. (weight and height will be combined to report BMI in kg/m2).

Physical activity was chosen through the Taiwanese version of the IPAQ-LV. Results were determined by first understanding how much total time was spent on physical activity. This was then multiplied by the frequency of the activity (i.e., per week and per day). The purpose of this was to evaluate the difference in physical activity of participants.
