Cardiorespiratory Fitness Level Alters Blood Pressure Responses Induced By Histamine H1- And H2-Receptor Blockade During Dynamic Exercise, Albert A. Lira Jr., Dustin J. Lirazan, Ronaldo U. Meneses, Sung J. Yun, Jong-Kyung Kim
Cardiorespiratory Fitness Level Alters Blood Pressure Responses Induced By Histamine H1- And H2-Receptor Blockade During Dynamic Exercise, Albert A. Lira Jr., Dustin J. Lirazan, Ronaldo U. Meneses, Sung J. Yun, Jong-Kyung Kim
International Journal of Exercise Science: Conference Proceedings
Epidemiological studies have reported that greater cardiorespiratory fitness (CRF) is associated with lower blood pressure (BP). Histamine receptor-mediated peripheral vasodilation contributes to postexercise hypotension and lowing exercising BP responses. Previously, our laboratory found that overactive BP responses to exercise were induced by the inability of histamine receptors in individuals with prehypertension. However, it is still unknown that CRF can impact BP responses elicited by the inability of the receptors. Purpose: This study was to assess whether aerobic fitness is effective in lowering excessive BP responses induced by the blockade of histamine receptors. Methods: In twelve male and female subjects (6 …
Acute Effect Of Dietary Supplementation With Grape Seed Extract Attenuates Blood Pressure Increase During Cold Pressor Test In Prehypertensive Men, Sarah Greenawalt, Albert A. Lira Jr., Kylie J. Morrison, Ronaldo U. Meneses, Christen J. Lutz, Savannah C. Ulhir, Jong-Kyung Kim
Acute Effect Of Dietary Supplementation With Grape Seed Extract Attenuates Blood Pressure Increase During Cold Pressor Test In Prehypertensive Men, Sarah Greenawalt, Albert A. Lira Jr., Kylie J. Morrison, Ronaldo U. Meneses, Christen J. Lutz, Savannah C. Ulhir, Jong-Kyung Kim
International Journal of Exercise Science: Conference Proceedings
It is well documented that prehypertension or hypertension is associated with sympathetic overdrive and loss of parasympathetically mediated cardiac variability. Previous studies demonstrated that increased NO bioavailability reduced central sympathetic output. Despite the fact that grape seed extract (GSE) treatment increases the production of NO and improves endothelial function in prehypertensive males, no studies have assessed the effects of GSE on autonomic balance and autonomic function. PURPOSE: the aim of the study was to investigate the acute effect of dietary GSE supplementation on heart rate variability (HRV) and cold pressor test (CPT). METHODS: Six males were recruited in this study. …

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 …
Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Emily E. Latta, Shelby L. Gibbs, Eric J. Jones, Dustin P. Joubert
Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Emily E. Latta, Shelby L. Gibbs, Eric J. Jones, Dustin P. Joubert

Post-exercise hypotension (PEH) plays an important role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. PURPOSE: Determine the effects of pre-workout caffeine supplementation on the PEH response following resistance exercise in adults with above normal blood pressure (BP). METHODS: Participants (n = 7) were recreationally resistance trained men and women with above normal resting BP (SBP > 120 mmHg and/or DBP > 80 mmHg). Following BP screening and maximal …
Hemodynamics After Glucose Loading In Hispanics With And Without Family History Of Type 2 Diabetes, Gabriel Figueroa, Ryan D. Russell, Yu Lun Tai
Hemodynamics After Glucose Loading In Hispanics With And Without Family History Of Type 2 Diabetes, Gabriel Figueroa, Ryan D. Russell, Yu Lun Tai
International Journal of Exercise Science: Conference Proceedings
Type 2 Diabetes (T2D) increases cardiovascular mortality 4-fold. Although ~9% of Americans are diagnosed with T2D, T2D incidence is substantially higher in Hispanics and those with a have family history of T2D. Traditionally, T2D is diagnosed via oral glucose testing which has been shown to impair microvascular function. However, the effects of glucose loading on hemodynamics and arterial elasticity between healthy Hispanics with and without a family history of T2D are unclear. PURPOSE: To determine the effects of an oral glucose challenge (OGC) and a mixed meal challenge (MMC) on hemodynamics in healthy Hispanic individuals with and without family …
