Abstract
This study, grounded in the Theory of Planned Behaviour (TPB), aims to explore the multidimensional factors
influencing physical activity participation among women aged 20 – 55 in Guangzhou, constructing a theoretical
explanatory model aligned with local sociocultural characteristics. Semi-structured interviews were conducted with 24
Guangzhou women via focus group methodology, with thematic analysis of textual data performed using Nvivo 12
software. Findings reveal that Guangzhou women's physical participation behaviour is directly influenced by four core
factors: attitudes, subjective norms, perceived behavioural control, and sociocultural ecological context. Among these,
localised factors such as climate adaptability, Cantonese culture, tea-drinking culture, new media environments, and
sports facility accessibility stand out clearly, highlighting the structural and regional cultural challenges faced by urban
women in physical participation. Building upon these findings, the study integrated the Theory of Planned Behaviour
(TPB) framework with contextual local elements to construct a theoretical model of factors influencing women's sports participation in Guangzhou. This research not only expands the explanatory scope of TPB within studies of health behaviours among urban Chinese women but also provides empirical evidence and practical guidance for advancing gender-sensitive, culturally adapted sports promotion policies.
