Given the effects of physical activity on people's mental and physical health, a better understanding is needed of how physical activity interventions may impact the health of people who are unemployed or at risk of unemployment. This has added urgency in the context of rising rates of poverty-related unemployment in the UK in 2022. The current paper details the protocol used in the evaluation of the Back Onside Programme; a communitybased programme delivered by the Bradford Bulls Foundation in the Bradford District. The Programme supports people from low socio-economic backgrounds who are unemployed or at risk of unemployment to maintain regular physical activity through a ten-week physical activity intervention. This pilot study evaluates how a physical activity intervention may impact the mental and physical health of people who are unemployed or at risk of unemployment in an uncontrolled pragmatic pilot study. Four cohorts run back-to-back between May 2021 and May 2022, with separate groups for men (N = 100) and women (N = 60). Physical and wellbeing assessment at baseline and post-intervention is conducted. If the intervention works in this context for these individuals, it will be a promising low-cost community-based intervention for people who are unemployed or at risk of unemployment.
