Neurology: Poor aerobic exercise effect after concussion?

Concussion is usually defined as "temporary dysfunction of the central nervous system".

Some will forget what happened recently, and the pathological anatomy of the nervous system has not changed significantly

Aerobic exercise has become a useful way to assist in the management of a concussion

The study, published in the journal Neurology, recruited participants with recent concussions from exercise concussion clinics from September 1, 2018 to February 22, 2020

The researchers performed 107 exercise tests (initially 40 concussion patients, 37 healthy participants; 30 concussion patients at follow-up)

During the whole exercise process, FETCO2 increases with the increase of heart rate, reaches a high point, and decreases at higher exercise intensity

Among them, carbon dioxide explained more than 25% (R2>0.

There are at rest between the reaction of carbon dioxide by cerebrovascular reactivity (cerebrovascular events), and exercise induced cerebrovascular FETCO2 of a change in medium, there is statistical relationship of significance (R2 = 0.

In aerobic exercise after a concussion, the relationship between arterial carbon dioxide response and symptom aggravation may be mediated by the increased sensitivity of cerebrovascular to exercise-related carbon dioxide increase
