Are Age-Related Differences In Critical Power And Work-Prime Simply Due To Differences In Muscle Mass, Abigail Dorff

International Journal of Exercise Science: Conference Proceedings

Critical Power (CP) represents the threshold between sustainable, steady-state and unsustainable, non-steady-state exercise while Work Prime (W’) represents tolerable work above CP. The combination of CP and W’ potently influence exercise tolerance. We recently observed age-related reductions in both CP and W’ in active adults. Age-related decreases in muscle mass, which was not measured, could account for the reduction in CP and W’. PURPOSE: The aim of this study was to determine if CP and W’ are decreased in active, older adults when normalizing for muscle mass. METHODS: Single leg knee extension exercise was used to determine CP …

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 …
