摘要

Purpose

Home-based aerobic exercise using video instruction is common among older adults. However, they often struggle to accurately replicate the instructor's movements, particularly joint angles, leading to suboptimal exercise performance. This study investigated the impact of skeletal visual feedback on home exercise performance in community-dwelling pre-frail older adults. The study focused on movement accuracy, improvements in physical and mental well-being, self-efficacy, and exercise intensity.

Methods

A VR-based system incorporating skeletal visual feedback was developed. Thirteen participants in the Display Skeleton group and twenty-two in the No Display Skeleton group were recruited. The system's ability to enhance cardiorespiratory fitness and its test–retest reliability and concurrent validity, including a custom-made heart rate monitor, were assessed. Exercise intensity and movement accuracy were compared between the two groups after the 1st, 12th, and 24th exercise sessions. Participants completed the ‘Promotion or Regulation of Physical and Mental Function Scale’ to evaluate the system's impact on physical, psychological, and social functions, thus assessing its feasibility.

Results

Participants in the Display Skeleton group demonstrated significantly better exercise performance compared to the No Display Skeleton group, particularly at moderate exercise intensities. However, the performance difference diminished at high exercise intensities. The Display Skeleton group also showed significantly higher scores on the ‘Promotion or Regulation of Physical and Mental Function Scale’, indicating increased willingness to exercise (p < 0.001), perceived improvement in movement accuracy (p < 0.009), and enhanced overall exercise motivation (p < 0.001).

Conclusion

These findings suggest that home exercise systems for older adults incorporating skeletal visual feedback effectively improve exercise performance, movement accuracy, and exercise intensity.
