简要总结
Stroke often leads to reduced cardiovascular fitness, slower recovery after activity, poor physical capacity, and decline in quality of life. Exercise is known to support recovery after stroke, but the role of high intensity interval training has not been studied widely in Indian stroke survivors.
This randomized controlled trial aims to examine the effects of a four week program of treadmill based high intensity interval training on cardiovascular and functional outcomes in stroke survivors. A total of 32 participants aged 40 to 75 years will be randomly assigned into two groups. The intervention group will undergo supervised high intensity interval training three times per week for four weeks, while the control group will receive standard care without additional structured exercise.
The primary outcomes are resting heart rate, heart rate recovery after exercise, and functional capacity measured using the six minute walk test. The secondary outcomes are body composition measured by standard anthropometric methods and health related quality of life assessed.
Assessments will be done at baseline and after four weeks. This trial is expected to provide evidence on the safety and effectiveness of high intensity interval training for improving cardiovascular health, functional recovery, and overall well being in people recovering from stroke.
