Background: In comparison to adult-centred research in physical activity, there are far fewer studies which concentrate on hearing children's voices in physical activity research. Additionally, despite a number of studies which utilise a child-centred approach, the number of papers which concentrate on the complexities when conducting research with young people are extremely limited. Purpose: To consider power relationships between adult researchers and young participants. Also, to provide empirical examples of considerations related to an organic research process and the complexities that may arise during research with children. Data collection and analysis: An ethnographic approach is deemed useful when conducting research with children (Davis and Watson 2017), but particular considerations need to be taken into account as an adult conducting research with young people. The data for this paper was drawn from a year-long ethnographic study with junior korfball players (aged 11-13 years of age). The study involved participant observation where the researcher's role was 'coaches' help'. Nine semi-structured interviews took place 10 months into the study, and numerous informal conversations occurred throughout the research. Some of Foucault's ideas related power were utilised to discuss the way relationships were negotiated with children to maintain a child-centred approach to the research. Final thoughts: Adopting an organic approach to research may help reduce young participants' perceptions of adult power. Adopting a Foucauldian lens can also heighten awareness of power divisions and aid the researcher's sensitivity to their own use of techniques of power whilst in the field. Additionally, an organic approach can also help facilitate child-centred research which empowers participants and supports their voices being heard.
