Purpose. The SenseWear Armband (SWA) is a multisensor activity monitor that can be used in daily life to assess an individualâ��s\r\nphysical activity level (PAL). The primary goal of this study was to analyze the impact of different types of feedback on the PAL\r\nof Flemish employees. Methods/Design. We recruited 320 sedentary employees (age, 41.0 �± 10.7 years; BMI, 26.2 �± 4.2 kg/m2) to\r\nparticipate in the 12-month study. Participants were randomized into one of four intervention groups after being measured for 7\r\ndays and nights by means of the SWA: (1) a minimal intervention group received no feedback (MIG, n = 56); (2) a pedometer\r\ngroup was provided only information on their daily step count (PG, n = 57); (3) a display group received feedback on calories\r\nburned, steps taken, and minutes of physical activity by means of the SWA display (DG, n = 57); (4) a coaching group also received\r\nthe display and had weekly meetings with a Personal Coach (CoachG, n = 57).We hypothesize that participants receiving feedback\r\n(SG, DG, and CoachG) will have a greater increase in physical activity outcome variables compared to participants of the minimal\r\nintervention group.
