Objectives To test the efficacy of a multicomponent technology intervention for reducing daily sedentary time and improving cardiometabolic disease risk among sedentary, overweight university employees.Design Blinded, randomised controlled trial.Setting A large south-eastern university in the USA.Participants 49 middle-aged, primarily female, sedentary and overweight adults working in sedentary jobs enrolled in the study. A total of 40 participants completed the study.Interventions Participants were randomised to either: (1) an intervention group (N=23; 47.6+9.9years; 94.1% female; 33.2+4.5kg/m(2)); (2) or wait-list control group (N=17; 42.6+8.9 years; 86.9% female; 31.7+4.9kg/m(2)). The intervention group received a theory-based, internet-delivered programme, a portable pedal machine at work and a pedometer for 12weeks. The wait-list control group maintained their behaviours for 12weeks.Outcome measures Primary (sedentary and physical activity behaviour measured objectively through StepWatch) and secondary (heart rate, blood pressure, height, weight, waist circumference, per cent body fat, cardiorespiratory fitness, fasting lipids) outcomes were measured at baseline and postintervention (12weeks). Exploratory outcomes including intervention compliance and process evaluation measures were also assessed postintervention.Results Compared to controls, the intervention group reduced daily sedentary time (mean change (95%CI): -58.7min/day (-118.4to 0.99; p
