This investigation explored the impact of partial pressure end-tidal carbon dioxide (P ET CO 2 ) alterations on temporal neurovascular coupling (NVC) responses across cardiac cycle and influence biological sex via a complex visual scene-search task (“ Where’s Waldo?”). 10 females males completed five puzzles, each with 40 seconds eyes open 20 closed, under P clamped at ∼40 mmHg (eucapnia), ∼55 (hypercapnia), ∼25 (hypocapnia). Cerebral blood velocity (CBv) in middle posterior cerebral...
Cerebral hemodynamics have been quantified during exercise via transcranial Doppler ultrasound, as it has high-sensitivity to movement artifacts and displays temporal superiority. Currently, limited research exists regarding how different modalities postural changes impact the cerebrovasculature across cardiac cycle. Ten participants (4 females 6 males) ages 20-29 completed three tests (treadmill, supine, upright cycling) volitional fatigue. Physiological data collected included middle...
Background Concussion education is recommended to increase concussion knowledge, beliefs, and reporting intentions. The Awareness Training Tool for Youth (CATT-Youth) a 40-minute e-Learning module developed high school–aged youth. Aim aim of the study was evaluate changes in intentions school youth from Calgary, Canada, following completion CATT-Youth Methods This used modified stepped-wedge trial design. High classes were randomly assigned an intervention (Ix) or delayed (DIx) group. Ix...
Abstract There are differences within the literature regarding upper frequency cut‐off point of dynamic cerebral autoregulation (CA) high‐pass filter. The projection pursuit regression approach has demonstrated that limit is ∼0.07 Hz, whereas another [transfer function analysis (TFA) phase approaching zero] indicated a theoretical for filter 0.24 Hz. We investigated how these limits accurately represent CA limit, in addition to extending earlier findings with respect biological sexes and...
Abstract This study applied alterations in partial pressure of end‐tidal carbon dioxide () to challenge dynamic cerebral autoregulation (dCA) responses across the cardiac cycle both biological sexes. A total 20 participants (10 females and 10 males; aged 19–34 years) performed 4‐min bouts repeated squat–stand manoeuvres (SSMs) at 0.05 0.10 Hz (randomized orders) with clamped ∼40 mmHg. The protocol was for hypercapnic (∼55 mmHg) hypocapnic (∼20 conditions. Middle artery (MCA) posterior (PCA)...
