The teaching profession requires an understanding of teachers' and students' emotions, and teachers' emotions can influence their teaching practice, professional development and pedagogical approaches. Furthermore, emotions are embodied and they may have a detrimental effect on wellbeing if they are not addressed properly. This paper explores the emotional dimensions of preservice primary teachers' practicum experiences in physical education (PE). Body journals were used to collect data which were analysed using a Sociology of Emotions (SoE) approach. The findings revealed that preservice teachers' emotions manifest physically during their practicum, especially at particular junctures, such as at the beginning of their teaching. Preservice teachers felt the need to make a 'good impression' within the school through the regulation of their emotions as they faced continual challenges to succeed in unfamiliar teaching circumstances. The conclusions of this study demonstrate the benefits of providing opportunities for preservice PE teachers to reflect on their emotions during the practicum and the consequences that these may have on their bodies and teaching practices.
