社区老年人对"零时间运动"的感知和体验:一项质性研究OA

Background In the context of population aging,community-dwelling older adults commonly experience insufficient physical activity and difficulty maintaining regular exercise.Zero-time exercise(ZTEx)is lifestyle-based and fragmented,making it easier to integrate into daily life;however,qualitative evidence on older adults'lived experiences and perceptions of ZTEx remains limited.Objective To explore how community-dwelling older adults understand ZTEx and its practical characteristics in everyday life,and to provide experience-based evidence for health promotion in older populations.Methods A qualitative research design was adopted.From April to June 2025,20 older adults from three communities in Nanchang City were selected using purposive sampling.Data were collected through non-participant observation and semi-structured interviews,and analyzed using Colaizzi's seven-step method to identify and summarize themes.Results Among the 20 participants,10 were men(50%)and 10 were women(50%),with a mean age of 66.1±3.4 years.Four themes(adoption drivers,exercise patterns,health perceptions,and sustainability challenges)and 12 subthemes were identified.Participants generally perceived ZTEx as a lifestyle-oriented,low-threshold activity strategy,mainly used to maintain daily functional ability,enhance confidence in mobility,and promote self-health management.Continued practice was influenced by differences in understanding exercise intensity and safety,physical functional limitations,and insufficient professional guidance.Conclusion ZTEx demonstrates good acceptability and practical potential among community-dwelling older adults.However,sustained implementation still depends on further improvements in standardized guidance and community support conditions.
