Traditionally final year experimental research projects have involved students undertaking work in a research laboratory supervised by academic or research staff. With increased student numbers and pressure on research time and resources, alternative projects are necessary. Experimental projects are highly sought after by undergraduates particularly those who wish to continue into post-graduate research. Research projects can be run in settings other than research laboratories and they can allow students some degree of autonomy in the design of the experimental questions and procedures. Students can also benefit by gaining experience of different settings, in this case working with the Universities Sport and Physical Activity Team. This experimental project, taken by two Neuroscience students, required no lab space but was a hypothesis driven project, with direct input to the design by the students, and addressed a current and highly relevant issue. Many studies link an increase in physical activity to improved mental and social wellbeing. These studies have relied on self-reported levels of exercise which may not accurately reflect the actual level or frequency of activity in subjects (1,2). In this project, trackers (Fitbit charge2) were worn by volunteers, recruited from the final year student population at the University of Bristol. Activity trackers were worn for 14 continuous days and at the end of the two weeks participants completed the Warwick-Edinburgh Mental Well-Being Scale. Participants completed a questionnaire at the start of the study to indicate how frequently they exercised. The weight and height of participants were also collected. Analysis of the data indicated a weak correlation between total minutes exercised and wellbeing score (r = 0.21) and between average daily step count and wellbeing (r = 0.26). There was no correlation between BMI and wellbeing for all participants but when analysed separately for male and female participants there was a positive correlation for males and wellbeing (r = 0.69) and negative for females (r=-0.33) Increasing the power of the experiment could be achieved with more students running the project as more experimenters could recruit a greater number of participants and share the collation of data from tracker accounts. Given access to all the data that can be obtained from the trackers (resting heart rate, moderate exercise duration, aerobic exercise duration, step count, sleep quality) students could focus on different aspects of those data for their individual project dissertations. A further extension of the project could be to recruit 2 groups of participants recording normal levels of activity in one group and assessing the impact on wellbeing of participation in additional physical activity sessions during the data collection period in a second. Students running the project reported enjoying the involvement of shaping the project and the relevance of the research to their own experiences.
