Cerebral blood velocity responses during and after sprint interval exercise in healthy young adults

. SIE was followed by 60 min of hypocapnia, and blood pressure was significantly lowered 10-20 and 40-55 min post SIE. However, resting MCAv was not altered, and PCAv was only lower 5 min post SIE. Resting MCAv phase and gain, and PCAv phase were largely unaltered apart from the first 5 min post SIE. The ability to buffer changes in blood pressure during repeated squat-stand maneuvers remained intact 60 min post SIE, although a greater fall in MCAv and PCAv was noted during a single sit-to-stand transition at this time.
