The Impact Of Rivalry Antecedents On Mediated Demand For An Individual Sport, Lamar Reams, Terry Eddy

Human Movement Sciences & Special Education Faculty Publications

In contrast to research examining the social-psychological aspects of how sport fans perceive rivalry games in team sports, far less is known regarding the impact rivalries have on mediated consumer demand, a marketing outcome of interest to sport researchers and practitioners. Guided by economic demand theory, the current study developed a model to empirically examine the impact of Tyler and Cobbs' (2015) rivalry antecedents (conflict, peer, bias) on fan interest for an individual sport. The three-dimensional framework provided the foundation for the selection of thirteen rivalry-related variables, in addition to control determinants established from prior literature. Results from the estimation …

Comparison Of A Head Mounted Impact Measurement Device To The Hybrid Iii Anthropomorphic Testing Device In A Controlled Laboratory Setting, Eric Schussler, David Stark, John H. Bolte, Yun Seok Kang, James A. Onate

Rehabilitation Sciences Faculty Publications

Background: Reports estimate that 1.6 to 3.8 million cases of concussion occur in sports and recreation each year in the United States. Despite continued efforts to reduce the occurrence of concussion, the rate of diagnosis continues to increase. The mechanisms of concussion are thought to involve linear and rotational head accelerations and velocities. One method of quantifying the kinematics experienced during sport participation is to place measurement devices into the athlete’s helmet or directly on the athlete’s head.

Purpose: The purpose of this research to determine the accuracy of a head mounted device for measuring the head accelerations experienced by …

Epidemiology Of Knee Sprains In Youth, High School, And Collegiate American Football Players, Daniel R. Clifton, James A. Onate, Eric Schussler, Aristarque Djoko, Thomas P. Dompier, Zachary Y. Kerr

Rehabilitation Sciences Faculty Publications

Context: Assessment of health-related quality of life (HRQOL) after injury is important. Differences in HRQOL between nonathletes and athletes and between injured and uninjured athletes have been demonstrated; however, the evidence has not been synthesized.

Objective: To answer the following questions: (1) Does HRQOL differ among adolescent and collegiate athletes and nonathletes? (2) Does HRQOL differ between injured adolescent and collegiate athletes or between athletes with a history of injury and uninjured athletes or those without a history of injury?

Data Sources: We systematically searched CINAHL, MEDLINE, SPORTDiscus, and PubMed. A hand search of references was also conducted. Study Selection: …

The Ability Of The Landing Error Scoring System To Detect Changes In Landing Mechanics: A Critically Appraised Topic, Claire E. Pointer, Tyler D. Reems, Emily M. Hartley, Johanna M. Hoch

Rehabilitation Sciences Faculty Publications

Clinical Question: Is there evidence to suggest that the Landing Error Scoring System (LESS) is able to detect functional changes in landing mechanics in healthy individuals after participation in an injury prevention program (IPP)? Clinical Bottom Line: In a healthy, physically active population, there is strong evidence to support the use of the LESS as an outcome measure for changes in landing mechanics after the implementation of IPPs. Clinicians should consider the LESS as an evaluative tool for measuring the efficacy of IPPs in clinical practice.

Overweight, Obesity, And Screen-Time Viewing Among Chinese School-Aged Children: National Prevalence Estimates From The 2016 Physical Activity And Fitness In China—The Youth Study, Yujun Cai, Xihe Zhu, Xueping Wu

Human Movement Sciences & Special Education Faculty Publications

Purpose: This study presents the most recent estimates of prevalence of overweight, obesity, and screen-time viewing among Chinese school-aged children. Demographic differences in these estimates between sexes and resident locales were also examined.

Methods: Cross-sectional analyses of 116,615 Chinese school children 9 to 17 years of age who participated in the 2016 Physical Activity and Fitness in China—the Youth Study project. Outcomes were the prevalence of children's overweight (body mass index [BMI] ≥ 85th - < 95th percentile) and obesity (BMI ≥95th percentile) (defined by the Working Group on Obesity in China) and not meeting screen-time viewing recommendations (“not meeting” was defined as more than 2 h per day of viewing activities after school). Analyses were conducted on the whole sample and by school grade cohorts (primary, junior middle, junior high schools), sex, and residence locales (urban, rural).

Results: Overall, 14.4% (95% confidence interval (CI): 13.8%-15.0%) of children and adolescents were overweight, 11.9% (95% CI: 11.0%-13.0%) were obese, and 36.8% (95% …

Gopher Fitstep Pro Accuracy When Measuring Steps And Moderate-To-Vigorous Physical Activity, Ali Brian, Justin A. Haegele

Human Movement Sciences & Special Education Faculty Publications

Background: The Gopher FITStep Pro (GFSP) is a commercially available objective physical activity monitor that records steps taken and moderate-to-vigorous physical activity (MVPA).

Objective: The purpose of this study was to evaluate the accuracy of the GFSP for measuring steps taken in a guided walking condition and MVPA during planned fitness activities.

Method: University-aged participants (N = 35, M_age = 20) wore two GFSP (right and left side) pedometers and one ActiGraph GT3X+ accelerometer during both conditions.

Results: Paired samples t-tests determined that self-step counts in the guided walking condition were not significantly different …

Frequency Of Chronic Gastrointestinal Distress In Runners: Validity And Reliability Of A Retrospective Questionnaire, Patrick B. Wilson

Human Movement Sciences & Special Education Faculty Publications

Gastrointestinal (GI) symptoms may affect up to 90% of competitors during endurance races. Studies have typically assessed GI symptoms retrospectively or only over an acute timeframe, and information on the validity and reliability of the questionnaires employed is lacking. This investigation aimed to estimate the frequency of GI distress experienced by runners over 30 days and to establish the validity and reliability of a retrospective GI symptom questionnaire. Runners (70 men, 75 women) recorded GI symptoms with a prospective journal for 30 days. Retrospective GI symptom data were then collected after the 30-day period on two occasions within one week. …

Autologous Blood And Platelet-Rich Plasma Injections In The Treatment Of Achilles Tendinopathy: A Critically Appraised Topic, Cori Sinnott, Hayley M. White, Jennifer W. Cuchna, Bonnie L. Van Lunen

Rehabilitation Sciences Faculty Publications

Clinical Scenario: Achilles tendinopathy is a painful condition commonly affecting the general and athletic population. It presents with localized pain, stiffness, and swelling in the midportion of the Achilles tendon. The physical stress placed on the tendon results in microtrauma, which leads to subsequent inflammation and degeneration. While it is not surprising that this condition affects the physically active, nearly one-third of Achilles tendinopathy cases occur in sedentary individuals. Etiology for this condition stems from a change in loading patterns and/or overuse of the tendon, resulting in microscopic tearing and degenerative changes. There are numerous causes contributing to the …
