Objective: To evaluate the effects of a 4-week “BikeRacer-Multitasking” computer-based training program on various outcomes, such as multitasking ability, and performance in complex situations on a bicycle exercise course, in comparison with two active control groups. Materials and Methods: Randomized controlled study including 56 participants aged 65 years or older. The intervention group (IG) performed 4 weeks of training with the BikeRacer-Multitasking computer game, in which two tasks had to be carried out at the same time: steering a bicycle on a given path, reacting to a target stimulus as quickly as possible, and ignoring three further distractor stimuli. The first control group (CG1) trained with a version of the BikeRacer game without the multitasking component, and the second control group (CG2) played Sudoku. All three groups performed questionnaire-based psychometric performance tests and tasks on a real-life bicycle exercise course twice, before and after the intervention. Results: Processing speed improved significantly over time in all three groups. Selective attention (correct answers) significantly improved in the IG and CG1, but not in CG2 ( P = 0.022 for the interaction). Multitasking ability and divided attention significantly improved in IG, decreased in CG1, and showed no change in CG2 ( P = 0.005 for the interaction). All three groups showed significantly better performances in some of the multitasking components in the bicycle course after the training...
