The research on SB is relatively new, with much evidence regarding its negative health effects gathered within the last decade. Office workers exhibit pronounced sedentary habits, with studies indicating they can spend up to 82% of their working day sitting. To address this issue, workplaces are responsible for promoting physical activity and minimising SB among employees. In this context, one potential strategy for reducing SB and its associated risks could be implementing active breaks (ABs). ABs are defined as brief, structured periods of physical activity or exercise. This quasi-experimental pilot study aims to implement workplace ABs programme aimed at interrupting SB among the University of Bologna (Italy) workers, and it will include both intervention and control groups. The intervention group will participate in an 8-week ABs programme. The findings from this study could establish a robust basis for future large-scale research on the effectiveness of ABs interventions in workplace settings. No data are available.

Data indicate that regular exercise may preserve β-cell function in people recently diagnosed with T1D, but the role of islet-reactive CD8⁺ T-cells is unclear. In a randomised crossover design, this study will determine the impact of a 12-week exercise programme on the frequency and proliferative state of islet-reactive CD8⁺ T-cells in the peripheral blood of 20 adults diagnosed with T1D within the past 3 years. The exercise intervention will consist of three high-intensity interval training sessions per week (6-10 1 min intervals >80% maximum heart rate, with 1 min rest), the duration of which will incrementally increase from 14 to 22 min. Habitual physical activity and diet will be maintained during control and washout periods. At weeks 0, 12, 24 and 36, a fasting blood sample will be collected to quantify the frequency, phenotype and proliferative activity of islet-reactive CD8⁺ T-cells (primary outcome) and various clinical parameters.
