A Description Of Variability Of Pacing In Marathon Distance Running, Tom Haney Jr., John Mercer Dr.

International Journal of Exercise Science

The purpose of this study was twofold: 1) to describe variability of pacing during a marathon and 2) to determine if there is a relationship between variability of pacing and marathon performance. Publically available personal global positioning system profiles from two marathons (Race 1 n = 116, Race 2 n = 169) were downloaded (http://connect.garmin.com) for analysis. The coefficient of variation of velocity (Velcov) was calculated for each profile. Each profile was categorized as finishing in under 3.9 hours, between 3.9 and 4.6 hours, or longer than 4.6 hours. Linear and quadratic lines of best fit were computed to describe …

Knee Osteoarthritis And The Efficacy Of Kinesthesia, Balance & Agility Exercise Training: A Pilot Study, Matthew W. Rogers, Nauris Tamulevicius, Marius F. Coetsee, Beth F. Curry, Stuart J. Semple

International Journal of Exercise Science

Kinesthesia, balance and agility (KBA) neuromuscular exercises are commonly used for rehabilitation of lower extremity injuries. KBA combined with strength training (ST) reportedly improves function among persons with knee osteoarthritis (OA), but independent effects of KBA are unknown. The purpose of this study was to determine the efficacy of KBA exercises, independent of ST, to improve function among persons with knee OA. Twenty participants (69.3, SD 11.4 y) were randomized to 8 weeks, 3-days per week, instructor-lead KBA or ST groups. Self-reported physical function (difficulty with daily living activities such as walking, bending, stair climbing, etc.) was measured at baseline …

The Effect Of Energy Patches On Substrate Utilization In Collegiate Cross-Country Runners, Ryan E. Fiddler, Doug Smith, Bert Jacobson, Crishel Klein, Aric Warren, Matt O'Brien, Brennan Thompson, Lee Everett

International Journal of Exercise Science

It is well established that an increased capacity of skeletal muscle to oxidize fatty acids can spare glycogen and delay the onset of fatigue in mild- to moderate-intensity exercise. The purpose of the following study was to examine the effect of LifeWave® energy patches on non-protein substrate utilization in Division-1 cross-country runners. To determine the effect of the patches subjects were pretested to establish baselines and randomly assigned to an experimental (EX) or placebo (PL) group. Twenty-two trained male (n = 11; mean ± SD, age = 21.1 ± 2.6years, height = 179.6 ± 4.2cm, body mass = 71.4 ± …

Physical Activity And Screen Time Sedentary Behaviors In College Students, Charles J. Fountaine, Gary A. Liguori, Arupendra Mozumdar, John M. Schuna Jr.

International Journal of Exercise Science

It is well established that Americans are not meeting physical activity (PA) guidelines and college students are no exception. Given the lack of regular PA, many health promotion professionals seek to discover what barriers to PA may exist. A common explanation is screen time (ST), which is comprised primarily of television viewing, computer use, and the playing of video games. The purpose of this study was to present descriptive data on college students’ PA and sedentary behavior and to assess if any evidence exists to suggest displacement between sedentary behaviors and PA in college students. Students completed an online health …

Accuracy Of The Omron Hbf-500 Body Composition Monitor In Male And Female College Students, Michael I. Pribyl, John D. Smith, G Richard Grimes

International Journal of Exercise Science

The Omron HBF-500 is an inexpensive body composition monitor that incorporates both hand-to-hand and foot-to-foot electrical impedance technology. At this time, studies examining the accuracy of the HBF-500 when estimating percent body fat (%BF) are scarce and if this instrument gains popularity due to its claimed precision, comparisons against validated techniques should be conducted. The purpose of this study was to assess the accuracy of the Omron HBF-500 body composition monitor using the BOD POD as a criterion. Forty-eight men and 33 women participated in the study (24.3±6.9 years, 171.0±10.0 cm, 78.4±18.0 kg, 26.6±5.1 kg/m2). Participants were asked to refrain …

Child Obesity In Context: Ecology Of Family And Community, Joel E. Williams

International Journal of Exercise Science

Minority and low socioeconomic status groups have the highest rates of overweight and obesity. Children from these families face a greater risk for weight-related health problems such as diabetes, heart disease and cancer as compared to their non-minority and more affluent peers. Factors from the larger physical, social, and cultural environments, and within families, influence weight status among children. Many of these factors are yet to be identified and relationships among known factors are complex and not well understood. The National Institutes of Health and U.S. Department of Agriculture have proposed a research agenda for social and behavioral scientists to …

Voluntary Wheel Running During Weight Loss Leads To Differential Changes In Monocytes, Compared To Forced Treadmill Running, Katie C. Carpenter, Kelley Strohacker, Whitney L. Breslin, Thomas W. Lowder, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

High-fat feeding and subsequent weight gain may contribute to innate immune dysfunction. Weight loss via calorie restriction and exercise represent one means to restore normal immune function. The purpose of the study was to examine how 8- weeks of aerobic exercise and low-fat diet affects weight gain, monocyte concentration, and monocyte cell-surface expression of TLR2, TLR4, CD80, and CD86. For 12- months, 24 male CD-1 mice underwent a pre-treatment phase, consuming either a low fat (10% fat) or high-fat (60% fat) diet ad libitum. Mice were randomly assigned to one of four groups (N=6/group): CN (low-fat sedentary), V-EX (voluntary wheel …

Choreographic Design And Process Of Dance, Kathleen Higgins

Undergraduate Research Conference

When I began the choreographic process, I was inspired by all of the emotions one might feel at a dance audition. However, with much though and manipulation of my original movement, I realized that the body image a dancer has of herself, and the body image for which she is continuously striving, was the underlying message that I wanted my choreography to communicate.

The Effects Of Physical Education Credit Producing Activities On High School Students, Jonathan Denton

Undergraduate Research Conference

The original intent for this project was to see what summative information could be drawn using the FITNESSGRAM. Researchers wanted to relate the FITNESSGRAM to variables like academic performance, amount of physical education, and the student’s general idea of physical education. Over the past few years, researchers have found that students with a higher score on the FITNESSGRAM have a higher academic score on the T.A.K.S., better attendance, and less behavioral problems. Also, researchers were interested in determining if a participant’s satisfaction level of the physical education experience had any impact on the FITNESSGRAM variables. This descriptive research was designed …

The "Playing" Field: Attitudes, Activities, And The Conflation Of Play And Games, Chad R. Carlson

Faculty Research and Creative Activity

Many philosophers have attempted to describe the nature of play and games. In doing so, they have come to a number of similar conclusions. Some authors speak of play and games interchangeably, while others regard them as two distinct phenomena. However, even some of those who attempted to distinguish games from play provided ambiguous or otherwise confusing descriptions. The end result has been a tendency to conflate the two entities. This conflation is so commonplace that we regularly speak of participating in all and any games as “playing games.” In this paper I address the issue of play-game conflation and …

The Comparison Of Hamstring/Quadriceps Strength Ratio In The Dominant Versus The Non-Dominant Leg Of Elite Female Artistic Gymnasts, Marina Moure

Human Movement Studies & Special Education Theses & Dissertations

The majority of the injuries in women's artistic gymnastics occur in the lower limbs (Marshall et al, 2007). Hamstring muscle strains are prevalent in sports that involve sprinting (Ekstrand & Quillist, 1985; Orchard, 2001; Croisier et al., 2008) with a high reinjury ratio (Orchard, 1993; Orchard, 1997). Recent studies have linked an increase of muscle injury rate in the lower limbs to strength muscle imbalance between legs and the relation between the hamstring and quadriceps strength (Croisier et al., 2002; Yamamoto, 2008; Sugiura et al, 2008). In order to determine if there is an imbalance in women's artistic gymnastics, forty-three …

The Effect Of Maturation On Hip And Knee Kinetics And Kinematics During An Unanticipated Sidestep Cutting Task In Male Youth Lacrosse Players, Crystal M. Sullivan

Human Movement Studies & Special Education Theses & Dissertations

The incidence of noncontact anterior cruciate ligament (ACL) knee injuries has been studied extensively and has been reported as one of the highest injuries amongst high school and collegiate athletes. Little research has been focused on maturational changes in relation to the risk factors of such an injury. The purpose of this study is to determine if there is a difference between pre-pubescent (PRE), pubescent (MID) and postpubescent (POST) male lacrosse athletes indicated by knee and hip kinetics and kinematics during an unanticipated sidestep cutting task (SS). Thirty-one male participants between the ages of nine and fourteen were recruited and …

Sensory Information Utilization And Time Delays Characterize Motor Developmental Pathology In Infant Sitting Postural Control, Joan E. Deffeyes, Regina T. Harbourne, Wayne A. Stuberg, Nikolaos Stergiou

Journal Articles

Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age. Sitting postural sway data were collected using a force plate, and the data were used to train a neural network controller of a model of sitting posture. The trained networks were then probed for sensitivity to position, velocity, and acceleration information at various time delays. Infants with typical development developed a higher reliance on velocity information in control in the anterior-posterior axis, and used more types of information in control in the …

Peak values of heart rate, VO₂, exercise ventilation, and respiratory exchange ratio were measured at the end of each maximal treadmill test. Significant decreases were found in pulmonary function measures (FEV₁, FVC and MVV) with increasing load. Most peak responses …

Dietary Energy Density And Successful Weight Loss Maintenance, Hollie A. Raynor, Emily L. Walleghen, Jessica L. Bachman, Shannon M. Looney, Suzanne Phelan, Rena R. Wing

Kinesiology and Public Health

Research shows a positive relationship between dietary energy density (ED) and body mass index (BMI), but dietary ED of weight loss maintainers is unknown. This preliminary investigation was a secondary data analysis that compared self-reported dietary ED and food group servings consumed in overweight adults (OW: BMI=27–45 kg/m2), normal weight adults (NW: BMI=19–24.9 kg/m2), and weight loss maintainers (WLM: current BMI=19–24.9 kg/m2 [lost≥10% of maximum body weight and maintained loss for ≥5 years]) participating in 2 studies, with data collected from July 2006 to March 2007. Three 24-h phone dietary recalls from 287 participants (OW=97, NW=85, WLM=105) assessed self-reported dietary …

Practitioner Advice And Gestational Weight Gain, Suzanne Phelan, Maureen G. Phipps, Barbara Abrams, Francine Darroch, Andrew Schaffner, Rena R. Wing

Kinesiology and Public Health

Background: The purpose of this study was to investigate receipt of gestational weight gain advice in prenatal care and ideal and expected gestational weight gain outcomes for normal weight and overweight/obese women.

Methods: This was a cross-sectional study of normal weight (n=203) and overweight/obese (n=198) women in early (<16 >weeks) pregnancy.

Results: Less than half of participants (41.7%) reported receiving weight gain advice from a practitioner. In multivariate models, pregravid weight status was not significantly related to receiving advice. However, women with lower income (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.13-0.77, p=0.01), younger …
