Effects and Mechanism of Two Hybrid Exercise-cognitive Trainings in Mild Ischemic Stroke With Cognitive Decline

The participant will cycle on a stationary bike for 30 minutes, which includes a 3-min warm-up phase followed by the aerobic training components (25 minutes), then a 2-min cool-down phase. The target heart rate during the aerobic training phase will be 40 to 70% of maximal heart rate (HRmax). After cycling, the participant will engage in a 30-minute of computer-based cognitive training program using BrainHQ (Posit Science Inc., San Francisco, CA, USA). The following are the areas of training: visuospatial processing, attention, memory, language, and logical thinking.

The dual-task training group will cycling concurrently with the computer-based cognitive training. The training principle of cycling and cognitive training is similar to the SEQ group; however, the training intensity will be adjusted according to each participant's ability.

The control participants will receive 60 minutes of health-related rehabilitation programs which involves non-aerobic physical exercise (e.g., muscle stretching, range of motion exercises, relaxation techniques) and unstructured cognitive related rehabilitation programs (e.g., watch health-related videos or read newspapers or magazines and then answer the content-related questions raised by the therapist).
