It is estimated that 36 million individuals in the U.S. suffer from migraines. While pharmacological treatments are most often prescribed, adverse side effects cause nearly 70% to delay or avoid taking medication. Treatments such as exercise, that have fewer side effects than medications, are needed. While exercise is effective, not all migraineurs benefit (40% were classified as non-responders in one study), indicating certain aspects should be evaluated. The PURPOSE was to determine if exercise prescribed at a time-of-day in synchrony versus out of synchrony with circadian preference (chronotype) affected responder versus non-responder status when considering monthly migraine load.

Kinesiophobia Prevalence Among College Athletes, Lindsey R. Mcneely, Robert I. Dudley
Kinesiophobia Prevalence Among College Athletes, Lindsey R. Mcneely, Robert I. Dudley
International Journal of Exercise Science: Conference Proceedings
The fear avoidance model indicates that fear of re-injury and movement related fear (kinesiophobia) can foster avoidant behaviors leading to potentially injurious changes in movement. The Tampa Scale of Kinesiophobia (TSK-11), an 11-question survey, measures movement related fear. While much of the kinesiophobia literature has focused on individuals with chronic pain, there is little evidence on the prevalence of kinesiophobia among collegiate athletes, a population with high frequency of injury. What little evidence exists indicates a connection between high kinesiophobia and injurious movement patterns. PURPOSE: Given the lack of data on collegiate athletes, the purpose of this investigation is to …

Autonomic And Cardiovascular Responses To Acute Exercise In Children With Autism Spectrum Disorder, Allison T. Bui, Gustavo Aldama, Kauionalani P. Kekuawela, Jacob A. Manriquez, Areum K. Jensen
International Journal of Exercise Science: Conference Proceedings
Autism Spectrum Disorder (ASD) is a complex neurological disorder identified in early childhood and is characterized by impaired social interaction and atypical behaviors. Limited studies reported that children with ASD tend to have higher heart rate (HR) and blood pressure (BP) at rest compared to typically developing children (TDC). Previously, we reported that HR and blood flow (BF) did not alter during exercise while BP significantly increased in ASD. Thus, we thought that ASD may have impaired autonomic control of cardiac output via differential contribution of HR and stroke volume (SV) to regulate BP during acute exercise. PURPOSE: To …
