The Need For Advanced Cardiac Life Support Certification For Open-Water Lifeguards At Huntington Beach, Ca, Daniel Jerome, Peter R. Chambers, Steve Reuter, John Porcari

International Journal of Aquatic Research and Education

The number of people visiting U.S. beaches increased in 2007 to more than 240 million people. This increase in activities does not come without danger. Lifeguards maintain beach safety, but little research is available to assist us in determining appropriate certification levels for lifeguards. The authors analyzed various injuries that occurred in the open-water environment of Huntington Beach, CA. Based on the nature of the injuries, they attempted to determine the level of training lifeguards needed. The vast majority of injuries (99%) were soft-tissue injuries, musculoskeletal injuries, or environmental injuries. It was felt that lifeguards with first-aid and basic-life-support (BLS) …

Transcranial Doppler Estimation Of Cerebral Blood Flow And Cerebrovascular Conductance During Modified Rebreathing, Jurgen A.H.R. Claassen, Rong Zhang, Qi Fu, Sarah Witkowski, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Clinical transcranial Doppler assessment of cerebral vasomotor reactivity (CVMR) uses linear regression of cerebral blood flow velocity (CBFV) vs. end-tidal CO2 (PETCO2) under steady-state conditions. However, the cerebral blood flow (CBF)-PETCO2 relationship is nonlinear, even for moderate changes in CO2. Moreover, CBF is increased by increases in arterial blood pressure (ABP) during hypercapnia. We used a modified rebreathing protocol to estimate CVMR during transient breath-by-breath changes in CBFV and PETCO2. Ten healthy subjects (6 men) performed 15 s of hyperventilation followed by 5 min of rebreathing, with supplemental O2 to maintain arterial oxygen saturation constant. To minimize effects of changes …

Handling Immediate Medical Care At Aquatic Facilities: Do We Need Different Levels Of Lifeguard Certification?, Leland Yarger

International Journal of Aquatic Research and Education

The first-responder and professional-rescuer training materials and training programs consider lifeguards to be first responders in emergencies (Aehlert, 2005; American Red Cross, 2001). This article asks readers to consider whether our agency lifeguard-training programs reflect a philosophy that truly view and prepare lifeguards as first responders. If not, I challenge readers to consider whether we should alter our hiring, staffing, and in-service training procedures at aquatic facilities based on the scope and need for providing adequate emergency care at those facilities.

Cerebral Hemodynamics After Short- And Long-Term Reduction In Blood Pressure In Mild And Moderate Hypertension, Rong Zhanf, Sarah Witkowski, Qi Fu, Jurgen A.H.R. Claassen, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

This study tested the hypothesis that acute reduction in blood pressure (BP) at the initial stage of antihypertensive therapy compromises brain perfusion and dynamic cerebral autoregulation in patients with hypertension. Cerebral blood flow velocity and BP were measured in patients with mild and moderate hypertension and in healthy volunteers at baseline upon reduction of BP within 1 to 2 weeks of administration of losartan/hydrochlorothiazide and after 3 to 4 months of treatment. The transfer function between beat-to-beat changes in BP and cerebral blood flow velocity was estimated to assess dynamic autoregulation. After 1 to 2 weeks of treatment, BP was …

Health and Sport Science Faculty Publications

Recruitment and retention of student employees are important considerations for any recreational sports department, large or small, because student employees impact both the quantity and quality of programs and services. This article proposes a strategy for establishing partnerships with academic departments to aid in the recruitment and retention of student employees. These partnerships benefit students, the recreational sports department, academic departments, and university student retention efforts. Following a description of this strategy is an example of a partnership that has been successfully established at one Midwestern university.

The Theory Of Planned Behavior: Predicting Physical Activity And Cardiorespiratory Fitness In African American Children, Jeffrey J. Martin, Pamela Hodges Kulinna, Nate Mccaughtry, Donetta Cothran, Joe Dake, Gail Frances Fahoome

Kinesiology, Health and Sport Studies

The purpose of our study was to evaluate the ability of the Theory of Planned Behavior (TPB) to predict African American children’s moderate to vigorous physical activity (MVPA) and cardiorespiratory fitness. Children (N = 548, ages 9–12) completed questionnaires assessing the TPB constructs and MVPA and then had their cardiorespiratory fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Commonly used Structural Equation Modeling fit indices suggested the model was an adequate representation for the relationships within the data. However, results also suggested an extended model which was examined and supported. Tests of direct paths from subjective …

The volunteers underwent unilateral knee extension (Biodex System 3) testing to determine their individual isokinetic peak torque at 60, 90, and 120° ·s-1. The contraction speeds and the rest periods between sets (30, 60 and 90 s) were randomly performed in three different days with a minimum rest period of 48 hours. Significant differences between and within sets were analyzed using a One Way Analysis of …

A Social Cognitive Perspective Of Physical-Activity-Related Behavior In Physical Education, Jeffrey J. Martin, Pamela Hodges Kulinna

Kinesiology, Health and Sport Studies

The purpose of the current study was to examine student and teacher physical-activity-related behavior using the theory of planned behavior and self-efficacy theory. Although teachers reported an overwhelmingly positive attitude toward teaching physical activity lessons to promote fitness development, they only devoted 4% of their class time to actually demonstrating and promoting fitness. Students were quite sedentary during class spending 61% of class time sitting, standing, or lying down. Using hierarchical regression analyses, teachers' attitudes toward teaching physically active physical education classes accounted for 50% of the variance in teachers' intention. Teachers who demonstrated/promoted fitness and who limited their general …

Effects Of Gender And Hypovolemia On Sympathetic Neural Responses To Orthostatic Stress, Qi Fu, Sarah Witkowski, Kazunobu Okazaki, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

We tested the hypothesis that women have blunted sympathetic neural responses to orthostatic stress compared with men, which may be elicited under hypovolemic conditions. Muscle sympathetic nerve activity (MSNA) and hemodynamics were measured in eight healthy young women and seven men in supine position and during 6 min of 60° head-up tilt (HUT) under normovolemic and hypovolemic conditions (randomly), with ∼4-wk interval. Acute hypovolemia was produced by diuretic (furosemide) administration ∼2 h before testing. Orthostatic tolerance was determined by progressive lower body negative pressure to presyncope. We found that furosemide produced an ∼13% reduction in plasma volume, causing a similar …

Persistent Sympathetic Activation During Chronic Antihypertensive Therapy, Qi Fu, Rong Zhang, Sarah Witkowski, Armin Arbab-Zadeh, Anand Prasad, Kazunobu Okazaki, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Previous studies have demonstrated that antihypertensive treatment resets baroreflex control of heart rate (HR) and increases cardiac vagal baroreflex sensitivity. However, it is uncertain whether baroreflex control of muscle sympathetic nerve activity (MSNA) also resets after treatment. We tested the hypothesis that chronic antihypertensive therapy alters baroreflex regulation of MSNA in patients with untreated moderate hypertension. Seven newly diagnosed patients with systolic blood pressure (BP) of 159 5 mm Hg (mean SE) and diastolic BP of 103 4 mm Hg were studied before and after 1 to 2 weeks ´ and 3 months (chronic) of antihypertensive treatment with losartan– hydrochlorothiazide …

Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler

Health and Sport Science Faculty Publications

Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Inhibition Of Nitric Oxide Inhibition Of Nitric Oxide Synthase Does Not Alter Dynamic Cerebral Autoregulation In Humans, Rong Zhang, Thad E. Wilson, Sarah Witkowski, Jian Cui, Craig G. Crandall, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

The aim of this study was to determine whether inhibition of nitric oxide synthase (NOS) alters dynamic cerebral autoregulation in humans. Beat-to-beat blood pressure (BP) and cerebral blood flow (CBF) velocity (transcranial Doppler) were measured in eight healthy subjects in the supine position and during 60° head-up tilt (HUT). NOS was inhibited by intravenous N G-monomethyl-L-arginine (L-NMMA) infusion. Dynamic cerebral autoregulation was quantified by transfer function analysis of beat-to-beat changes in BP and CBF velocity. Pressor effects of L-NMMA on cerebral hemodynamics were compared with those of phenylephrine infusion. In the supine position, L-NMMA increased mean BP from 83 ± …

Vasoconstrictor Reserve And Sympathetic Neural Control Of Orthostasis, Qi Fu, Sarah Witkowski, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

Background—We tested the hypothesis that individual variability in orthostatic tolerance is dependent on the degree of neural and vasomotor reserve available for vasoconstriction.

Methods and Results—Muscle sympathetic nerve activity (MSNA) and hemodynamics were measured in 12 healthy young volunteers during 60° head-up tilt (HUT), followed by a cold pressor test (CPT) in HUT. Orthostatic tolerance was determined by progressive lower-body negative pressure (LBNP) to presyncope. The same protocols were performed randomly in normovolemic and hypovolemic conditions. We found that mean arterial pressure increased and stroke volume decreased, whereas heart rate (HR), MSNA, and total peripheral resistance (TPR) increased during HUT …

Kinesiology, Health and Sport Studies

The purpose of this study was to determine how physical education students' cardiovascular responses as determined by mean heart rate, standard deviation of heart rate, and percentage of time in target heart rate zone varied according to student characteristics. Participants were 505 students in Grades 3 through 12. The Polar Accurex Plus heart rate telemetry system was used to measure the physiological load on the cardiovascular system. Three-way ANOVA results suggested that heart rate patterns in physical education varied according to gender, grade, and activity. For example, secondary school girls were more active in individual activities while secondary school boys …

The Development Of A Physical Education Teachers' Physical Activity Self-Efficacy Instrument, Jeffrey J. Martin, Pamela Hodges Kulinna

Kinesiology, Health and Sport Studies

In the present investigation a questionnaire was developed to assess physical education teachers' self-efficacy for teaching classes in which their students were engaged in high levels of physical activity (i.e., at least 50% of class time). Exploratory and confirmatory factor analyses resulted in the development of a 16-item, 4-factor, multidimensional physical education teachers' physical activity self-efficacy scale (PETPAS) that produced reliable and valid scores. The Student factor reflected teachers' efficacy for managing students who didn't enjoy or value physical activity. The Time factor was indicative of teachers' efficacy when they didn't have enough time to teach. The Space factor reflected …

Nitric Oxide Synthase Inhibition Does Not Affect Regulation Of Muscle Sympathetic Nerve Activity During Head-Up Tilt, Jian Cui, Rong Zhang, Thad E. Wilson, Sarah Witkowski, Craig G. Crandall, Benjamin D. Levine

Exercise and Sport Studies: Faculty Publications

To test the hypothesis that systemic inhibition of nitric oxide (NO) synthase does not alter the regulation of sympathetic outflow during head-up tilt in humans, in eight healthy subjects NO synthase was blocked by intravenous infusion of NG-monomethyl-L-arginine (L-NMMA). Blood pressure, heart rate, cardiac output, total peripheral resistance (TPR), and muscle sympathetic nerve activity (MSNA) were recorded in the supine position and during 60° head-up tilt. In the supine position, infusion of L-NMMA increased blood pressure, via increased TPR, and inhibited MSNA. However, the increase in MSNA evoked by head-up tilt during L-NMMA infusion (change in burst rate: 24 ± …

In the current study, social cognitive theory was examined with athletes with disabilities. More specifically, hierarchical and self-regulatory performance self-efficacy, self-regulatory training self-efficacy, outcome confidence, and affect were examined with wheelchair road racers (N = 51). In accordance with social cognitive theory, moderate to strong significant relationships among 3 types of self-efficacy and outcome confidence were found (rs = .41 - .78). All forms of self-efficacy and positive affect (rs = .39 - .56) were also related providing additional support to social cognitive theory and the important relationships among training and performance related efficacy and affect in …

We Want To Play Too, Peter J. Titlebaum, Kate Brennan, Tracy Chynoweth

Health and Sport Science Faculty Publications

The Americans with Disabilities Act (ADA) requires that persons with disabilities be integrated to the maximum extent possible, and that these persons cannot be excluded from participation. Intramural directors need to be proactive in this area. The benefits of intramural sports are vast, and they help many students become part of the college community.

Forming an alliance with the Disability Services on campus, the first step, is the most vital aspect of making these programs successful. It is important to remember the difference between what can be done and what must be done. Even with the best of intentions, it …

Exercise and Sport Studies: Faculty Publications

We measured blood erythropoietin (EPO) concentration, arterial O2 saturation (SaO2), and urine PO2 in 48 subjects (32 men and 16 women) at sea level and after 6 and 24 h at simulated altitudes of 1,780, 2,085, 2,454, and 2,800 m. Renal blood flow (Doppler) and Hb were determined at sea level and after 6 h at each altitude (n = 24) to calculate renal O2 delivery. EPO increased significantly after 6 h at all altitudes and continued to increase after 24 h at 2,454 and 2,800 m, although not at 1,780 or 2,085 m. The increase in EPO varied markedly …

Skin Cooling Maintains Cerebral Blood Ffow Velocity And Orthostatic Tolerance During Tilting In Heated Humans, Thad E. Wilson, Jian Cui, Rong Zhang, Sarah Witkowski, Craig G. Crandall

Exercise and Sport Studies: Faculty Publications

Orthostatic tolerance is reduced in the heat-stressed human. The purpose of this project was to identify whether skin-surface cooling improves orthostatic tolerance. Nine subjects were exposed to 10 min of 60° head-up tilting in each of four conditions: normothermia (NT-tilt), heat stress (HT-tilt), normothermia plus skin-surface cooling 1 min before and throughout tilting (NT-tiltcool), and heat stress plus skin-surface cooling 1 min before and throughout tilting (HT-tiltcool). Heating and cooling were accomplished by perfusing 46 and 15°C water, respectively, though a tube-lined suit worn by each subject. During HT-tilt, four of nine subjects developed presyncopal symptoms resulting in the termination …

Determinants Of Teachers' Intentions To Teach Physically Active Physical Education Classes, Jeffrey J. Martin, Pamela Hodges Kulinna, Robert C. Eklund, Brett Reed

Kinesiology, Health and Sport Studies

The purpose of the present investigation was to examine determinants of teachers' intentions to teach physically active physical education classes (i.e., spend at least 50% of class time with the students engaged in moderate to vigorous physical activity). Based on the theories of reasoned action, planned behavior, and self-efficacy, a model was examined hypothesizing that teachers' intentions were determined by subjective norm, attitude, perceived behavioral control, and self-efficacy. Using hierarchical regression analyses, the theories of reasoned action and planned behavior were supported by accounting for 65% of the variance in intention due to the main effects of attitude and subjective …
