Physiological Response To Firefighting Activities Of Various Work Cycles Using Extended Duration And Prototype Scba, Richard M. Kesler, Ipek Ensari, Rachel E. Bollaert, Robert W. Motl, Elizabeth T. Hsiao-Wecksler, Karl S. Rosengren, Bo Fernhall, Denise L. Smith, Gavin P. Horn

Exercise Science Faculty Research and Publications

Firefighters’ self-contained breathing apparatus (SCBA) protects the respiratory system during firefighting but increases the physiological burden. Extended duration SCBA (>30 min) have increased air supply, potentially increasing the duration of firefighting work cycles. To examine the effects of SCBA configuration and work cycle (length and rest), 30 firefighters completed seven trials using different SCBA and one or two bouts of simulated firefighting following work cycles common in the United States. Heart rate, core temperature, oxygen consumption, work output and self-reported perceptions were recorded during all activities. Varying SCBA resulted in few differences in these parameters. However, during a second …

Performance Profiles Of Collegiate And Master’S Swimmers: A Validation Study, Lyle Edmond Robelot

LSU Master's Theses

The purpose of this proposal is to link the gold standard power test on land (Wingate test) to an in-water power test. There is a lack of information on power in the water and would be beneficial in tracking swimmers progress throughout a season and between seasons. Power curves of individuals on the Wingate test will be compared to those of In-water tests to see weather this water test is valid. The experiment will follow IRB rules and regulation and the staff will adhere to the safety conditions set forth by the IRB.

Understanding Gender Differences In Sports-Related Concussions Among High School Athletes: Implications For Diagnosis, Treatment, And Management, Hillary Grady-Speckhals

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Growing research on both the immediate and long-term effects of sports-related concussions (SRCs) in professional athletes has called attention not only to understanding the impact of concussions in high school athletes, but has also focused on understanding how SRCs may impact female athletes differently than male athletes (Covassin & Elbin, 2011; Kirkwood, Yeates, & Wilson, 2006). There are many studies that have highlighted the neurocognitive, academic, and socioemotional implications of these brain injuries on developing youth, but there are few studies that focus on gender differences in adolescent athletes (Daneshvar, Nowinski, McKee, & Cantu, 2011; Kirkwood, et al., 2006). Understanding …

Health and Sport Sciences Faculty Scholarship

Compression and cold therapy used separately have shown to reduce negative effects of tissue damage. The combining compression and cold therapy (cryocompression) as a single recovery modality has yet to be fully examined. To examine the effects of cryocompression on recovery following a bout of heavy resistance exercise, recreationally resistance trained men (n =16) were recruited, matched, and randomly assigned to either a cryocompression group (CRC) or control group (CON). Testing was performed before and then immediately after exercise, 60 minutes, 24 hours, and 48 hours after a heavy resistance exercise workout (barbell back squats for 4 sets of 6 …

The Relationship Between Sport Participation And Chronic Diseases Among Men In The Usa: An Examination Of The Behavioral Risk Factor Surveillance System, Jennifer Pharr, Nancy L. Lough

School of Public Health Faculty Research

Sport participation has been associated with lower rates of chronic diseases when compared to other forms of physical activity (PA) among women. However, we do not know if this relationship holds true for men. The purpose of this study was to examine the relationship between sport participation and men’s health and chronic diseases in the USA. This study was a secondary data analysis of the 2015 national Behavioral Risk Factor Surveillance System (BRFSS) survey. Participants were questioned extensively about their PA behaviors. Seventy-six different activities were identified and these activities were categorized as sport, conditioning exercise, recreation, or household tasks …

Metabolic Biomarkers Following A Short And Long Bout Of High-Intensity Functional Training In Recreationally Trained Men, Brian Kliszczewicz, Robert Buresh, Emily E. Bechke, Cassie M. Williamson

Faculty Articles

Glucose regulation is a fundamental process of metabolic function, and is acutely altered by physical activity. High-Intensity Functional Training (HIFT) is a form of exercise performed using combinations of various modalities and durations. It is unknown if the metabolic responses to HIFT are similar to more commonly studied modalities (e.g., cycling and treadmill exercise), or if exercise duration will influence glucose regulation. The purpose of this study was to determine the effect of a Short (< 5-min) and Long (15-min) bout of HIFT on plasma metabolic biomarkers. Ten apparently healthy males (28.11 ± 5.09yrs) participated in this study. Two HIFT sessions (SHORT and LONG) were performed in a crossover fashion. Blood plasma was collected at four time points: PRE, POST, 1HR, and 3HR in order to examine glucose (GLU), insulin (INS), epinephrine (E), and norepinephrine (NE) responses. No trial dependent difference between the SHORT and LONG bouts in GLU (p=0.054), INS (p=0.671), E (p=0.078), and NE (p=0.194). A time effect was observed in both bouts only at POST for GLU (p<0.001), INS (p=0.011), E (p<0.001), and NE (p<0.001). All times returned to baseline values (p>0.05), except for lowered 3HR E (p=0.007). This study demonstrated that both SHORT and LONG bouts of HIFT elicited GLU, INS, E, and NE …

Sex Differences In Spatial Accuracy Relate To The Neural Activation Of Antagonistic Muscles In Young Adults, Agostina Casamento-Moran, Sandra K. Hunter, Yen-Ting Chen, Min-Hyuk Kwon, Emily J. Fox, Basma Yacoubi, Evangelos A. Christou

Exercise Science Faculty Research and Publications

Sex is an important physiological variable of behavior, but its effect on motor control remains poorly understood. Some evidence suggests that women exhibit greater variability during constant contractions and poorer accuracy during goal-directed tasks. However, it remains unclear whether motor output variability or altered muscle activation impairs accuracy in women. Here, we examine sex differences in endpoint accuracy during ankle goal-directed movements and the activity of the antagonistic muscles. Ten women (23.1 ± 5.1 years) and 10 men (23 ± 3.7 years) aimed to match a target (9° in 180 ms) with ankle dorsiflexion. Participants performed 50 trials and we …

Physical Activity Modulates Corticospinal Excitability Of The Lower Limb In Young And Old Adults, Hamidollah Hassanlouei, Christopher W. Sundberg, Ashleigh E. Smith, Andrew Kuplic, Sandra K. Hunter

Exercise Science Faculty Research and Publications

Aging is associated with reduced neuromuscular function, which may be due in part to altered corticospinal excitability. Regular physical activity (PA) may ameliorate these age-related declines, but the influence of PA on corticospinal excitability is unknown. The purpose of this study was to determine the influence of age, sex, and PA on corticospinal excitability by comparing the stimulus-response curves of motor evoked potentials (MEP) in 28 young (22.4 ± 2.2 yr; 14 women and 14 men) and 50 old adults (70.2 ± 6.1 yr; 22 women and 28 men) who varied in activity levels. Transcranial magnetic stimulation was used to …

Lessons To Be Learned: How A Comprehensive Neurobiological Framework Of Atypical Reading Development Can Inform Educational Practice, Ola Ozernov-Palchik, Xi Yu, Yingying Wang, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty Publications

Dyslexia is a heritable reading disorder with an estimated prevalence of 5–17%. A multiple deficit model has been proposed that illustrates dyslexia as an outcome of multiple risks and protective factors interacting at the genetic, neural, cognitive, and environmental levels. Here we review the evidence on each of these levels and discuss possible underlying mechanisms and their reciprocal interactions along a developmental timeline. Current and potential implications of neuroscientific findings for contemporary challenges in the field of dyslexia, as well as for reading development and education in general, are then discussed.

The Effect Of Hyperthermic Whole Body Heat Stimulus (Sauna) On Heat Shock Protein 70 And Skeletal Muscle Hypertrophy In Young Males During Weight Training, Brandon C. Jones Mr.

All NMU Master's Theses

The traditional Finnish steam sauna is theorized to aid skeletal muscle hypertrophy by stimulating Heat Shock Protein 70 (HSP70), which acts as a molecular chaperone to the folding of functional skeletal muscle. The aim of this study was to investigate if stimulating HSP70 by using a sauna (45 – 50 ͦC, 80% Humidity) three times per week, for 15 minutes, could aid skeletal muscle hypertrophy during six weeks of resistance training in a young (21.38 ± 1.9 yrs.), recreationally trained male population. Thirteen subjects were randomly distributed into 3 groups [resistance Training + sauna (RT+S, n=5), RT + Relaxation (RT+R, …

Post-Activation Potentiation: Decay Or Fatigue Delay, Ryan L. Meidinger

All NMU Master's Theses

Post-activation potentiation has been shown to improve jumping performance and other ballistic activities. The improvements in performance have been attributed to four main mechanisms, but the most important mechanism to the current study is the improvement in neural activity that leads to greater levels of potentiation. Post-activation potentiation has been shown to be stimulated by a maximal activity, called a conditioning contraction, and can be used as a warm up. In studies that have not shown the effects of post-activation potentiation, the proposed reason is fatigue, but the interaction of post-activation potentiation and fatigue have not been thoroughly tested. The …

The Acute And Chronic Effects Of Highly Cushioned Shoes On Loading Characteristics In Recreational Runners, Jessica Corkin

All NMU Master's Theses

Recently, highly cushioned shoes (HCS) entered the running market, and manufacturers suggested extra cushioning potentially reduced injury rates through superior shock absorption, implying less impact upon foot strike versus other shoes. Hence, the purpose of this study was to examine the effects of a 4-week HCS intervention on running-related impact forces in adult recreational runners. We hypothesized HCS would result in altered force attenuation compared to standard cushioned shoes (SCS) at baseline. After 4-weeks, we speculated differences would not be attenuated. Twenty-nine healthy runners (18-60 yrs of age) who had never worn HCS were randomized to either an intervention (INV) …

What You Know Makes A Difference: Physical Activity Maintenance And Adherence Of Collegiate Students, Vista Beasley, Brooke Thompson, Patrick R. Young, Itay Basevitch

Journal of Counseling and Psychology

For decades, exercise psychology researchers dismissed health/exercise knowledge as a determinant of physical activity (PA). We sought to overturn this misconception, showing that psychological theory may serve as a basis for informing physical education curriculum. Based on social cognitive and self-determined motivation theories, we examined health/exercise knowledge as a determinant of collegiate students’ PA maintenance (i.e., ≥ 6 months of regular PA involvement); adherence to United States Department of Health and Human Services (USDHHS) 2008 PA guidelines; and PA types (i.e., aerobic, weight training). Collegiate students (n = 231) provided data via online survey. ANOVA analyses revealed that knowledge …
