METHODS: Thirty physically inactive, obese females (age= 26.07±4.4 years, height= 161.4±4.1 cm, weight= 89.8±8.1 kg and %body fat= 40.9 ±4.9%) were randomly …

Cardiac Vagal Tone Impairment Is Associated With Reduced Cerebral Blood Flow In Collegiate Athletes Following Concussion, Madeline N. Wainman, Justin Frantz, Benjamin Williams, Sydney H. Lyng, Tonia Sabo, Kathleen R. Bell Md, Sushmita Purkayastha

International Journal of Exercise Science: Conference Proceedings

Reduced cerebral blood flow (CBF) is linked to functional disturbances following concussion. Since cardiac vagal tone (an index of cardiac health) is associated with disturbances in the autonomic nervous system, deficits in CBF are likely associated with cardiac vagal tone impairment post-concussion. PURPOSE: The current study examined cardiac vagal tone and CBF on days 3, 21 and 90 following concussion in comparison to non-injured control athletes. The association between these two variables was also evaluated. METHODS: Concussed male and female collegiate athletes were evaluated day-3 (N=29), day-21 (N=25) and day-90 (N=17) post concussion and matched controls were enrolled (N=29). A …

Augmented Mechanoreflex In Type 2 Diabetic Rats: Piezo Channels, An Important Part Of The Puzzle?, Ann-Katrin Grotle, Yu Huo, Audrey J. Stone

International Journal of Exercise Science: Conference Proceedings

Type 2 diabetics (T2DM) have an abnormal cardiovascular response to exercise. The exercise pressor reflex, which is evoked by metabolic and mechanical stimuli arising from the contracting muscle, is a critical cardiovascular regulatory mechanism during exercise and is exaggerated in hypertension, heart failure, and peripheral artery disease. A recent study found that T2DM patients have an augmented metaboreflex. However, whether the mechanoreflex is also augmented in T2DM is not known. PURPOSE: The purpose of the study was to test whether the mechanoreflex is exaggerated in T2DM. Furthermore, we tested the contribution of mechano-gated Piezo 1 and 2 channels to …

A Family History Of Type 2 Diabetes May Impair Glucose Area Under The Curve In Young, Healthy Hispanics, Cesar Meza, Manuel Amador, Mario Garcia, Christopher Figueroa, Andrew Mcainch, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Obesity and type 2 diabetes are associated with impaired glucose homeostasis and blood lipid profiles. Further, a family history of diabetes (FH) increases the risk for development of insulin resistance. However, it is unclear whether a FH impairs glucose tolerance, blood glucose and lipid profiles in young, healthy, normoglycemic adults. PURPOSE: To investigate whether a FH impairs glucose tolerance and blood lipid profile in healthy, sedentary Hispanic males. METHODS: 22 sedentary, normoglycemic, Mexican American males (mean±SEM: age:23±0.56 yrs; BMI: 26.9±0.98 kg/m²) with/without FH participated in the study. Glucose tolerance was assessed by calculating glucose area under …

Relative Energy Deficit (Female Triad), Prystyn M. Covington

International Journal of Exercise Science: Conference Proceedings

ABSTRACT CLINICAL PRESENTATION & EXAM: The relative energy deficit also known as RED-S or the Female Triad, is a common occurrence with females. RED-S occurs due to many factors such as increased energy output, decreased energy intake, or can sometimes be caused by both. RED-S in females is diagnosed by three symptoms: abnormal eating habits, osteoporosis, and functional hypothalamic amenorrhea. The patient does not need to experience all three symptoms to be diagnosed with RED-S. The energy deficit affects physiological functions such as cardiovascular health, immunity, protein synthesis, along with menstrual functions in females. ANATOMY & PATHOLOGY: Osteoporosis is a …

Racial Differences In Vascular Function In Response To Mental Stress, Bryon Matthew Curtis, John Akins, Jordan C. Patik, Guillermo Olvera, Aida Nasirian, Jeremiah Campbell, R Matthew Brothers

International Journal of Exercise Science: Conference Proceedings

African Americans (AA) have a higher prevalence of hypertension and other cardiovascular (CV) complications compared to other populations. While the reasons for this elevated CV disease risk are multifactorial, vascular dysfunction is a key contributing factor. It has been previously shown that mental stress, induced by mental arithmetic, results in a significant increase in forearm blood flow (FBF). This response has been predominantly attributed to the release and vasodilatory effect of Nitric Oxide (NO). In this regard, a previous study has reported that AA have an attenuated increase in FBF as compared to Caucasians (CA) in response to mental stress, …

Stress Testing For Diastolic Dysfunction: An Old Approach To A New Question, T. Jake Samuel, Rhys Beaudry, Mark J. Haykowsky, Satyam Sarma, Michael D. Nelson

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: Currently, conventional cycle echocardiography is the recommended method for diagnosing diastolic dysfunction in patients with unexplained dyspnea upon exertion. However, this method has several underlying limitations including movement and respiratory artifact. These limitations are often exaggerated in patients who are obese and suffer from exertional dyspnea, and therefore limit its application in clinical diagnosis. Our group recently demonstrated that isometric handgrip echocardiography is a powerful sub-clinical diastolic discriminator that avoids the limitations of conventional cycle echocardiography and that can be easily implemented in the clinic. PURPOSE: However, to date it remains unclear how these two methodologies compare, and thus …

Exploiting Arm Swinging Dynamics To Reduce The Metabolic Cost Of Walking While Carrying Loads, Obioma B. Mcreynolds, Christopher J. Arellano

International Journal of Exercise Science: Conference Proceedings

Arm swing while walking at one’s optimal speed is primarily driven by passive pendulum mechanics, an energy saving mechanism that has been speculated to incur little to no metabolic cost. PURPOSE: In line with this idea, we set out to determine whether carrying loads on the swinging and non-swinging arms while walking would be less costly than carrying loads at other locations on the body. We hypothesized that carrying loads on the arms while restricted from swinging would demand a greater metabolic cost than carrying loads on the arms while naturally swinging. For relative comparisons, we also explored the cost …

Evidence Of Racial Differences In Microvascular Function Among College-Aged Women, Jordan C. Patik, Bryon M. Curtis, John D. Akins, Aida Nasirian, Guillermo Olvera, R Matthew Brothers

International Journal of Exercise Science: Conference Proceedings

Microvascular dysfunction contributes to the development of hypertension and insulin resistance. The black population is at an elevated risk of both conditions relative to other racial groups. Previous studies indicate that college-aged black men, compared to their white counterparts, have impaired microvascular function as assessed by post-occlusion reactive hyperemia (RH). It is unknown whether this racial disparity is present in healthy, young adult black (BW) and white women (WW). Furthermore, whether nitric oxide-mediated cutaneous microvascular hyperemia during local heating (LH) is different in these populations has not been determined. Purpose: The purpose of this study was to test the hypothesis …

Associations Between Leg Lean Mass And Arterial Function In Pre-Menopausal And Post-Menopausal Women., Stephen M. Fischer

International Journal of Exercise Science: Conference Proceedings

Vascular dysfunction has been associated to sarcopenia, the age-related impairment in skeletal muscle mass, strength, and performance, in postmenopausal women. Previous research has shown inverse relationships between leg lean mass (LM) and arterial stiffness (measured as carotid to femoral pulse wave velocity, cfPWV) or pressure wave reflection (augmentation index, AIx) in men and women. AIx is an appropriate vascular marker in young but not middle-age/older adults, especially in women.

Purpose: To examine the associations between leg LM and arterial function (cfPWV and aortic AIx adjusted to 75bpm (AIx@75)) in pre-menopausal (PRE-M) and post-menopausal (POST-M) women. Methods: 47 women (24 PRE-M, …
