Social Jetlag Inhibits Exercise-Induced Adaptations In The Heart And Alters Markers Of Mitochondrial Dynamics, Graham R. Mcginnis, Michael B. Dial, Elias M. Malek, Greco Neblina, Austin Cooper, Nikoleta Vasileva, Tanner Erwin

International Journal of Exercise Science: Conference Proceedings

Social jetlag (SJL), or the shifting of behavior and sleep times between weekdays and weekends, is a pervasive form of circadian rhythm disruption that affects nearly 70% of the population to some extent. The magnitude of SJL can be determined by the difference in the mid-sleep phase between weekends and weekdays. Higher levels of SJL have been associated with lower levels of cardiorespiratory fitness, and increased incidence of cardiometabolic disease, which may be due, in part, to mitochondrial dysfunction. However, no studies to date have evaluated the effects of long term SJL on cardiac mitochondrial dynamics. PURPOSE: To determine …

Effects Of Partial Hot Water Immersion On Postprandial Blood Glucose And Heart Rate Variability, Jeff Moore, Michael Buono

International Journal of Exercise Science: Conference Proceedings

The acute effects of heat therapy on glycemic markers oppose those of the chronic effects. While the postprandial glucose response is exaggerated during whole body heat exposure, chronic heat exposure lowers HbA1c. Additionally, the acute effects of heat therapy differ depending on the amount of body exposed to heat. Heating a single hand does not increase fasting glucose and lowers postprandial glucose. The opposing effects of partial and whole body heat exposure could be mediated in part from increased sympathetic nervous system (SNS) activity following heat stress. While heating the body increases muscular blood flow and glucose uptake, SNS activation …
