Summary

Both gait and cardiovascular dysfunction are primary factors limiting community ambulation for stroke individuals. Increased gait variability and asymmetry contributes to a higher risk of falls, leading to reduced physical activity, decreased cardiorespiratory endurance, and increased walking economy and sympathetic nervous system activity, thereby potentially triggering secondary strokes. Previous studies have primarily focused on the significant improvements in walking endurance and speed with high-intensity interval training (HIIT) on a treadmill, leaving a gap in understanding the effects of HIIT on oxygen uptake efficiency slope (OUES) and gait quality for stroke individuals using a stationary bicycle ergometer with exergaming. Therefore, this study aims to investigate the effects of HIIT using a stationary bicycle ergometer on improving cardiorespiratory fitness and gait quality in individuals with chronic stroke.

Conditions

• Chronic Stroke

Interventions

Type	Name	Description
OTHER	High-intensity interval training	Training on a stationary bike and integrated with exergame (Jbike, JACFIT, USA), the exercise games connect to a map in the app through sensors, allowing players from different countries to ride together and complete the map, thus increasing the diversity of the training, including a warm-up and cool-down at 30% HRR for 5 minutes each. Perform HIIT with 5 intervals at 80% heart rate reserve (HRR), each interval lasting 4 minutes, with 3-minute intervals at 40% HRR between each interval.
OTHER	Moderate intensity continuous training	Training on a stationary bike and integrated with exergame (Jbike, JACFIT, USA), the exercise games connect to a map in the app through sensors, allowing players from different countries to ride together and complete the map, thus increasing the diversity of the training, including a warm-up and cool-down at 30% HRR for 5 minutes each. Perform continuous exercise at 59% HRR for 35 minutes.
