We are seeking applicants for a self-funded PhD examining how artificial intelligence (AI) within digital fitness environments shapes body image and physical activity (PA) behaviours.
AI is increasingly embedded within social media and fitness platforms. On platforms such as TikTok and Instagram, generative AI tools are used to enhance or create idealised body imagery and content. Additionally, AI-powered fitness apps and chatbots (e.g. Chat GPT) can deliver exercise guidance, provide feedback, and motivational prompts. Despite rapid developments in generative AI, little is known about how this shapes individuals' self-perceptions, body image, and physical activity behaviours.
This project may adopt qualitative, quantitative, or mixed-method approaches and will be underpinned by theory in social psychology and/or exercise psychology.
Project focus
The specific focus of the PhD will be determined by the applicant, but may:
- Explore the impact of AI-generated or AI-enhanced fitness imagery and content on social media.
- Investigate how users interpret and relate to AI as a source of physical activity and exercise guidance/motivation.
- Consider how AI within digital fitness environments shapes body image and physical activity motivation.
Applicant profile
- Applicants should have a background in psychology, sport and exercise sciences, health psychology, public health, or a related field.
- Strong methodological skills (qualitative, quantitative or mixed methods)
