Relationship Between Cerebral Pulsatility Index And Vasodilatory Responsiveness To A Hypercapnic Challenge, Hannah E. Nagib, John Kolade, James E. Brown, Sajjad S. Moradi, R Matthew Brothers
Relationship Between Cerebral Pulsatility Index And Vasodilatory Responsiveness To A Hypercapnic Challenge, Hannah E. Nagib, John Kolade, James E. Brown, Sajjad S. Moradi, R Matthew Brothers
International Journal of Exercise Science: Conference Proceedings
Cerebral vascular function/health is critical for the precise matching of cerebral blood flow and thus oxygen/substrate delivery and the metabolic demands of the brain. Cerebral pulsatility index (PI) reflects cerebral vascular resistance and compliance, and therefore provides a measure of cerebral vascular stiffness. A higher PI indicates augmented stiffness and is associated with risk for/prevalence of advanced atherosclerosis and poor cerebral vascular autoregulation, both of which can predispose individuals to various detrimental conditions including stroke and reduced neurocognitive function. Cerebral vascular function/health is also often assessed by the vasodilatory response to a hypercapnic stimuli with higher responses being associated with …

Cerebral Vascular Response During A Hypercapnic Challenge With And Without Simultaneous Activation Of The Sympathetic Nervous System, Sajjad Moradi, James E. Brown, John Kolade, Hannah E. Nagib, R Matthew Brothers
International Journal of Exercise Science: Conference Proceedings
Cerebral vascular function/health is crucial for the maintenance of neurocognitive function and prevention of various neurocognitive and cerebral vascular conditions/diseases. Cerebral vascular function is commonly assessed by evaluating the vasodilatory response to a hypercapnic stimuli. A larger vasodilatory response is associated with more positive outcomes, while a blunted response is associated with an increased risk of cerebral vascular and neurocognitive diseases in the future. However, it remains unclear whether simultaneous activation of the sympathetic nervous system (SNS) can attenuate cerebral vasodilation during a hypercapnic challenge. PURPOSE: Therefore, this study tested the hypothesis that cerebral vascular vasodilatory responsiveness to a …

Impact Of Electrical Muscle Stimulation During Prolonged Sitting Combined With Mental Stress - A Pilot Study, Takanobu Okamoto, Lin-Sheng Chen, Daniela Charry, Kazumasa Manabe, Kelvin Phan, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
Mental stress superimposed on prolonged sitting is a common encounter. Both conditions are known to induce vascular dysfunction and impair executive function. While physical activity during sitting can mitigate these adverse effects, such activity is not always permissible for college students studying for important exams and office workers approaching critical deadlines. Electrical muscle stimulation (EMS) of the lower limb muscles has been proposed as a potential alternative to voluntary exercise and might help preserve vascular and cognitive function under these conditions. PURPOSE: This pilot study investigated whether EMS could attenuate arterial stiffening and cognitive decline induced by combined prolonged …
Patellofemoral Syndrome, Ava E. Dennis, Lindsay Spindler, Chuck Ruot
Patellofemoral Syndrome, Ava E. Dennis, Lindsay Spindler, Chuck Ruot
International Journal of Exercise Science: Conference Proceedings
CLINICAL PRESENTATION & EXAM: Patellofemoral syndrome is a common cause of knee pain, particularly in young female athletes. Studies suggest that multiple factors contribute to its development, including patellar maltracking, imbalance between the vastus lateralis and vastus medialis, hip instability and weakness, hamstring imbalance and tightness, and rear-foot eversion. Patients typically present with anterior knee pain, especially during weight-bearing activities that involve knee flexion. The condition can also cause knee stiffness after prolonged sitting with the knee flexed and may lead to knee buckling due to quadriceps weakness. Pain often intensifies with squatting. Tight hamstrings have been linked to …

Mental Toughness As A Catalyst For Social Team Cohesion: A Longitudinal Study In Female Collegiate Dancers, Alex J. Barber, Spencer A. Cavan, Andreas Stamatis
Mental Toughness As A Catalyst For Social Team Cohesion: A Longitudinal Study In Female Collegiate Dancers, Alex J. Barber, Spencer A. Cavan, Andreas Stamatis
International Journal of Exercise Science: Conference Proceedings
Cohesion bridges psychological and tactical aspects of how teams are structured and operate, significantly influencing both individual and team performance. Research has highlighted its particularly strong impact on women’s athletic success. Studies also show that women tend to prioritize social harmony, resolve conflicts collaboratively, and rely more on interpersonal relationships for team cohesion. While task-related cohesion (e.g., achieving performance goals) is often stable in elite athletes, social cohesion remains a malleable area for intervention. Mental toughness (MT), a trainable personal capacity, is theorized to enhance performance consistency under stress. However, MT’s role in fostering team cohesion, particularly social cohesion, remains …
