Influences of remote exercise training for community-dwelling older adults in Japan during the COVID-19 pandemic

[Purpose] The coronavirus disease (COVID-19) pandemic has caused sudden lifestyle changes. This study aimed to determine the limitations in activity and the influences of remote exercise training on community-dwelling older adults during a state of emergency in Japan. [Participants and Methods] In May 2020, during the COVID-19 state of emergency, we carried out a mail survey of community-dwelling older adults who had previously participated in a disability prevention program in Ami town, Ibaraki, Japan. The mail included a brochure on exercises and a DVD. The attached exercise program was comprised of 10 different exercises, which could be conducted in approximately 30 minutes. [Results] Of the 191 older adults, 73 responded to this survey (38.2%), of which 42 (58.5%) participants had decreased outdoor exercise activity, and 50 (68.5%) decreased the amount of time spent on physical activities during the COVID-19 state of emergency. There were significant reductions (19.2-22.5%) in the perceived exercise load for each posture after two weeks of remote exercise training with DVD (n=26). [Conclusion] Our results suggested that the remote exercise training with the brochure and DVD may be effective. Since this study involved a small number of participants, future studies should involve larger populations.
