The study also revealed that 89 percent of stroke patients with the highest level of physical activity recovered their motor skills, compared with 69 percent of the patients in the medium group, and 4 percent of those in the low category.
Ricciardi Ciocchini said the findings provide more evidence of the myriad health benefits that come from regular exercise.
"It is unlikely that a single drug or even a group of molecules will ever be slightly close to reaching the whole beneficial effects of physical activity," she said. "Practicing regular physical activity should be strongly recommended to all patients, and especially to those with cardiovascular risk factors."
Dr. Michael Frankel, director of vascular neurology at Emory University School of Medicine and director of the Marcus Stroke & Neuroscience Center at Grady Memorial Hospital in Atlanta, was intrigued by the findings but said more research is needed.
"While it is no surprise that people who are more physically fit will fare better than those who aren't, it is interesting to consider fitness as a key factor in determining whether acutely blocked cerebral arteries will open up in response to treatment," said Frankel. "These findings require further study to confirm."
Studies presented at scientific conferences should be considered preliminary until published in a peer-reviewed medical journal.
