Effects of computer feedback on adherence to exercise

A large fitness center setting was used to test the effects of a computer feedback system (FitLinxx Interactive Fitness Network) on adherence to exercise, attendance, and dropout. Healthy mixed-sex adult participants were evaluated on their maintenance of newly prescribed exercise. The control group (n=71) used standard exercise tracking and feedback during exercise sessions. The treatment group (n=93) used a specifically designed computer-based system that provided enhanced tracking, goal setting, and feedback. Analysis indicated significantly higher attendance and adherence in the treatment group who also had fewer dropouts by month, a larger number of days before dropout, and less over-all dropout (46%) over the 8 months tested. Discussion concerning the application of computerized feedback systems for maximizing clients' adherence within physical and cardiac rehabilitation and general fitness settings was given. Additional direct testing with different sample types and motivation was suggested.
