| Outline of Research at the Start |
Previously, I have developed a multicomponent lower extremity training (MLT) technique that was effective for older adults’ physical function and that it was easy to follow specially for older adults who possessed no equipment whatsoever, which indicated this technique had a high possibility of improving physical function by self-practice at home, whose self-efficacy contributed to exercise behavior. The present study aims to develop a home-based MLT technique in order to improve the frequency of self-practice without trainers and to evaluate its effects on older adults’ physical function.

| Outline of Annual Research Achievements |
During the COVID-19 pandemic, older adults have reported physical inactivity. For example, they did not participate in a community activities program in their regions because they would fear being exposed to COVID-19. Therefore, the first purpose of this study is to develop a home- based multicomponent lower extremity training (MLT) technique to improve the frequency of self-practice without a trainer, including non- participation in an offline fitness classes at community centers. The second of this study is to evaluate the home-based MLT technique’s effects on flexibility, muscle strength, and physical performance in older adults.
These work outcomes can help achieve the new intervention study without contact experts in the training period on older adults.
I have filmed exercises of the MLT technique that would be used for older adults (participants of this study) to perform in their home.
For older adult participants to do home-based exercise in their home, I have created a booklet and videos for a home-based exercise program.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
This study has been approved by the Ethics Review Board of Hiroshima University.
In addition, the intervention protocol for study 1(the first purpose) was designed, and participants for study 1 intervention have recruited. Study 1 intervention was completed. Study 2 intervention is underway: Participants have been recruited and performing the home-based exercises.
|
| Strategy for Future Research Activity |
In Study 1, participants were asked to evaluate self-efficacy about performing the exercises of MLT techniques for three months. The results of Study 1 have been analyzed to select exercises with high self-efficacy. Study 2 will be completed to evaluate the effect of the exercises having high self-efficacy, with older adults participating for three months. I will analyze the results of study 2.
