PhD students are among the most sedentary in higher education, but new research from Coventry University and Birmingham City University suggests that a simple combination of education and structured planning can help change that. The findings were published in the Academic Journal of Health Sciences and Research.
The study tracked the physical activity of 67 inactive PhD students over four weeks. It found that those who received both educational materials about the benefits of exercise and a planning tool to guide when, where and how they would be active showed the most significant improvements in weekly exercise levels. Participants in this group more than tripled their physical activity compared to those in a control group who received no support.
The real-world importance of the findings lies in how common inactivity is among PhD students. With academic pressure, unpredictable schedules and limited free time, many struggle to meet basic exercise recommendations. This increases the risk of developing serious health problems such as diabetes, depression and cardiovascular disease.
Natalie Quinn-Walker, a PhD researcher based at the University of Wolverhampton, reflected on the wider relevance of the research. “Physical inactivity is prevalent among university PhD students, impacting their health and well-being. Currently, there is a lack of awareness and research on PhD students’ physical activity; therefore, there is a need for future studies.”
Those in the combined intervention group reached an average of nearly 1,800 MET minutes of activity per week, up from a starting point of just over 350. MET minutes are a standard way of measuring physical activity by considering both intensity and time. Students who received only planning templates or educational material also improved, though to a lesser extent.
Across all groups, students who had better knowledge of the health risks linked to inactivity were more likely to increase their activity levels. Those who believed these risks applied personally were especially motivated. This supports the idea that belief in one’s own vulnerability is a strong driver of behaviour change.
Lawrence Bismarck Ndupu, the lead author of the study, remarked: “Enhancing knowledge about the risks of physical inactivity and fostering specific intentions to engage in physical activity can lead to meaningful behaviour change.”
Gender differences were smaller than expected. While male participants generally spent more time exercising from the third week onwards, there was no significant difference in overall activity levels between men and women throughout the full four weeks. Researchers believe this may be because all participants began the study with low levels of activity.
Kathryn Szymanska Barrett, co-author of the study, observed: “Males reported spending more time engaging in physical activity each week” but added that “total physical activity levels did not differ significantly by gender.”
The interventions were built on established behavioural science frameworks, including one that explains change as requiring capability, opportunity and motivation. The planning tool, which asked participants to link intentions to specific times and places, was found to improve follow-through by turning general goals into concrete actions.
These findings add to the growing body of evidence that brief and focused interventions can lead to real behaviour change among university students. While large-scale fitness programmes may be difficult to deliver across campuses, structured education paired with simple planning tools may be enough to support meaningful increases in physical activity.
Quinn-Walker concluded, “Universities and health practitioners should consider implementing combined educational and intention-based programs to promote physical activity among PhD students.”
