Key result
Hourly 10-minute exercise breaks prevent declines in cerebrovascular reactivity during prolonged sitting in healthy children.
Why the study?
The effects of interrupting prolonged sitting on cerebrovascular function in children were unknown.
Do hourly 10-minute exercise breaks prevent declines in cerebrovascular function during prolonged sitting in healthy children?
Do hourly 10-minute exercise breaks prevent declines in cerebrovascular function during prolonged sitting in healthy children?
Hourly 10-minute exercise breaks prevent the decline in cerebrovascular reactivity associated with prolonged uninterrupted sitting in healthy children.

Supports interrupting prolonged sitting in children; leaves open effects on clinical cerebrovascular outcomes.
and the slowed intracranial blood velocity onset response time to hypercapnia apparent with uninterrupted sitting in children. NEW FINDINGS: What is the central question of this study? What are the effects of interrupting prolonged sitting on cerebrovascular function in children? What is the main finding and its importance? Prolonged sitting results in declines in cerebrovascular reactivity, a valuable index of cerebrovascular health. Breaking up prolonged sitting with hourly 10 min exercise breaks prevented these changes. These initial findings suggest excessive sedentary behaviour does impact cerebrovascular function in childhood, but taking exercise breaks prevents declines.

Tallon et al. (2023) studied Healthy children. Exercise breaks vs. Uninterrupted sitting was evaluated on Cerebrovascular reactivity and intracranial blood velocity onset response time to hypercapnia. Breaking up prolonged sitting with hourly 10-minute exercise breaks prevented declines in cerebrovascular reactivity in healthy children.
