Blood Flow Through to the Brain Improved From Moderate Exercise

Since most of us can't walk immediately post-stroke, what exactly is your doctor doing to make sure that your brain gets this extra oxygenated blood to your brain. Better blood flow sounds like it would be great for your brain post-stroke. But then I'm not medically trained and obviously should never question the medical gods procedures.

Research indicates that it is never too late to enjoy the health benefits of moderate aerobic exercise. Brisk walking for 30 to 50 minutes 3 or 4 times each week for 3 months improved blood flow to the brain as much as 15% in a study of women.
At the start of the research, the scientists made use of Doppler ultrasonography to determine blood flow in the internal carotid arteries, which are found in the neck and provide the brain with important glucose and oxygen-rich blood. After examining each individual’s physical health and VO2 max (maximal oxygen uptake), which is the maximum amount of oxygen a person can make use of while exercising, the researchers customized training programs for each woman based on her fitness level.
Training began at a base pace of 50 to 60% of the individuals’ VO2 max for half an hour per session, 3 times a week. By the 3rd month, the researchers had increased the training sessions to 50 minutes each, 4 times each week, and added 2 more training sessions at 70 to 80% of their VO2 max for half an hour.
