Acute Effects of Cycling Dual-task in Parkinson´s Disease.

A 30-minute session of Forced Cycling aerobic exercise performed with lower limbs and free active cycling performed with upper limbs combined with cognitive stimuli. An intelligent cycle ergometer (Motomed Viva 2 Parkinson) will be used, at a reserve heart rate of 55-70% (Borg scale 12-14) during the active part. The forced cycling program will consist of a 6-minute passive warm-up part (40-60 RPM), a 20-minute active part (90 RPM), and a 4-minute passive cool down (40 RPM). The cognitive task will be a PowerPoint presentation structured in a way that is consistent with the phases of the cycling program. The passive phases (6 minutes of warm-up and 4 minutes of passive cycling back to cool down), images of the nearby environment will be played. For the active phase (20 minutes of assisted active cycling) the PowerPoint presentation will be structured with tasks related to: orientation, memory, calculation, language, similarities.
