Abstract

Purpose: Overweight individuals are at risk of intermediate hyperglycemia (IHG) [1]. Increasing physical activity (PA) in IHG is one method to reduce the risk of glucometabolic and cardiovascular (CV) complications [2]. This study investigates walking to music as a modality to increase moderate intensity PA and regulate glucometabolic disturbances. Patients and Methods: Participants were randomized to usual care (UC) or intervention group (IG) who completed a 6 month walking to music program. Physiological assessments for a range of variables (DEXA, flow mediated dilatation (FMD) and glucometabolic biomarkers) were completed at baseline, 4, 6 and 9 months (follow-up). Results: For IG group, walking compliance decreased with time however 71.4%, 79.5% and 73% of walking completed was moderate intensity at 4, 6 and 9 months. At 6 months IG FMD was significantly lower than UC and HbA1Cwas 5% lower. Other physiological markers were not altered. Conclusion: Walking to music may be a novel method to encourage moderate intensity PA. However, the majority of results demonstrate that this intervention was not more effective than UC in managing glucometabolic and CV biomarkers in IHG. Future interventions should include additional support for the entire study duration however this has cost implications.
