Background: Research suggests that e-cycling can positively impact physical activity (PA) behaviour and lead to improvements in fitness in healthy adults. Little is known about the impact of e-cycling in clinical populations for whom PA engagement is low. Purpose: Examine the association between an e-cycling intervention and PA and health in adults with type 2 diabetes mellitus (T2DM) to determine intervention promise. Methods: A parallel-group two-arm randomized waitlist-controlled pilot study was conducted. Forty eligible individuals were randomized into either the e-cycling intervention (Mage=58, 40%Female) or waitlist control (Mage=56, 35%Female). Participants in the e-cycling condition received e-bike training prior to a 12-week e-bike loan. Health outcomes, assessed at pretesting and immediately after the loan, included fasting glucose, HOMA-IR, cardiorespiratory fitness and health related quality of life (HRQoL). Overall PA was measured using the GT3X+ Actigraph accelerometer and PA intensity during e-cycling was measured using the Actiheart. Results: There was a favourable effect of the intervention on fasting glucose (difference in change scores between conditions: 0.67, 95%CI: -0.77, 2.11mmol/L) and HOMA-IR (0.58, 95%CI: -.033, 1.50). The intervention showed promise to improve HRQoL and cardiorespiratory fitness in comparison to the control group. E-cycling was performed at a moderate intensity (median%HR max=72%, IQR: 67, 80). There was an 18-minute increase in PA per week in the intervention group (95%CI: -84.72, 120.15), not seen in the control group (-27.64, 95%CI: -170.33, 79.61). Conclusions: E-cycling shows promise to positively impact health and PA in adults with T2DM and a fully-powered definitive trial is warranted. Funding: This study is funded by the National Institute for Health Research NIHR Bristol Biomedical Research Centre (Nutrition theme) at University Hospitals Bristol NHS Foundation Trust and The University of Bristol.
