Impact Of Blood Pressure Cuff Inflation Rates On Flow-Mediated Dilatation And Contralateral Arm Response, Hsin-Fu Lin, Mandeep Dhindsa, Takashi Tarumi, Steven Miles, Daniel Umpierre, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
Flow-mediated dilatation (FMD) is widely used as an index of nitric oxide-mediated vasodilator function, yet its methodology has not been well established. Previous research indicates that rapid inflations of a blood pressure cuff evoke systemic vasoconstriction as it was observed on non-occluded contralateral arm. This would potentially contribute to the well-known variability of FMD readings and could complicate the emerging evidence that non-occluded contralateral arm responses during the FMD procedure is associated with the presence of coronary artery disease. Purpose: To test the hypotheses that fast inflation of a blood pressure cuff could reduce FMD values and influence contralateral vasodilatory …

Non-Invasive Techniques To Track Stroke Volume During Simulated Uncontrolled Hemorrhage, Chelsea R. Barrera (Undergraduate), Gilbert Moralez, Jesus I. Lara, Ashley Martinez, William H. Cooke
International Journal of Exercise Science: Conference Proceedings
Battlefield medics and civilian first-responders have limited tools to assess the magnitude of blood loss in traumatically-injured patients. Accurate measures of stroke volume would provide important quantitative values for blood volume reductions, but battlefield medics and civilian first responders do not have access to standard laboratory methods to measure stroke volume. They may have access to arterial pulse wave detectors (for example, SPO2 monitors), but the usefulness of pulse wave detectors for determining stroke volume during hemorrhage has not been determined. PURPOSE: To compare stroke volumes estimated a with a standard laboratory rebreathing (RB) method to stroke volumes estimated from …

No Influence Of Ovarian Hormones On Cerebrovascular Responses To The Valsalva Maneuver, Jesus I. Lara (Undergraduate), Gilbert Moralez, Chelsea R. Barrera, Ashley Martinez, William H. Cooke
International Journal of Exercise Science: Conference Proceedings
Cerebral blood flow is modulated in part by arterial perfusion pressure and autonomic neural activity. Valsalva straining drives increases in cerebral perfusion pressure that may challenge cerebrovascular regulatory mechanisms. These challenges may be even greater during the normal menstrual cycle due to vasoactive influences of ovarian hormones. PURPOSE: To test the hypothesis that cerebral vascular responses to Valsalva straining are enhanced with increased plasma concentrations of estrogen and progesterone. METHODS: Twelve healthy eumenorrheic females (mean age 25 ± 1 yr; height 165 ± 3 cm; weight 66 ± 2 kg; mean ± SE) were studied during the early and late …

International Journal of Exercise Science: Conference Proceedings
Hemorrhage is the leading cause of death on the battlefield, but the magnitude of blood loss can be difficult to determine. Therefore, medics would benefit from advanced tools to detect blood loss. As skin temperature likely decreases with peripheral vasoconstriction, a portable thermographic imaging (TI) device capable of measuring skin temperature may assist in the detection hemorrhage. PURPOSE: To determine whether skin temperature measured with TI track stroke volume reductions during simulated hemorrhage. METHODS: We studied fifteen healthy volunteers (7 female and 8 male; 24±1 yrs; 171±3 cm; 69±3 kg). ECG, beat-by-beat finger arterial pressure (Finometer), respiratory rate (pneumobelt and …

Locomotive Biomechanics Wearing A Simulated Portable Life Support System During Varying Cognitive And Treadmill Grade Conditions, Brittany K. Sanchez, William E. Amonette
International Journal of Exercise Science: Conference Proceedings
Background: The Portable Life Support System (PLSS) worn by astronauts during Extravehicular Activity (EVA) is contained within a backpack. Due to the inherent mass of the PLSS, astronaut center of mass (COM) is altered during ambulation. Recent studies from our laboratory suggest shifts in the COM of the PLSS have minimal effects on exercising metabolism, although differences were observed in trunk angles during ambulation. During EVA, astronauts continuously perform cognitive tasks (CG). Due to the distractive nature of these tasks, safety may be compromised by altered biomechanics. Purpose: To quantify lower extremity kinematics while walking with a simulated PLSS at …

Association Of Aerobic Fitness And Metabolic Syndrome In Male Firefighters, Cara Kirby, Steven E. Martin, Brad S. Lambert, Nic P. Greene, John S. Green, Stephen F. Crouse
International Journal of Exercise Science: Conference Proceedings
Metabolic syndrome has been shown in numerous studies to be related to a higher incidence of coronary artery disease. A study by Jurca and coworkers (Med. Sci. Sports Exerc 36(8):1301-1307, 2004) found a relationship between aerobic fitness and the prevalence of metabolic syndrome in a group of men enrolled in the Aerobics Center Longitudinal Study (ACLS). In addition, recent work in our lab (Int J Exerc Sci 2(1): S43, 2009) has supported these findings. However, research exploring this relationship is still lacking in male firefighters, whose leading cause of line-of-duty deaths is heart attacks. Purpose: To further evaluate the association …
