Changes In Lower Extremity Biomechanics Due To A Short-Term Fatigue Protocol, Nelson Cortes, Eric Greska, Roger Kollack, Jatin Ambegaonkar, James A. Onate

Human Movement Sciences & Special Education Faculty Publications

Context: Noncontact anterior cruciate ligament injury has been reported to occur during the later stages of a game when fatigue is most likely present. Few researchers have focused on progressive changes in lower extremity biomechanics that occur throughout fatiguing.

Objective: To evaluate the effects of a sequential fatigue protocol on lower extremity biomechanics during a sidestep-cutting task (SS).

Design: Controlled laboratory study.

Setting: Laboratory.

Patients or Other Participants: Eighteen uninjured female collegiate soccer players (age 19.2 ± 0.9 years, height = 1.66 ± 0.5 m, mass 61.6 ± 5.1 kg) volunteered.

Intervention(s): The independent variable was fatigue level, with 3 …

Proceed To Checkout? The Impact Of Time In Advanced Ticket Purchase Decisions, Brendan Dwyer, Joris Drayer, Stephen L. Shapiro

Human Movement Sciences & Special Education Faculty Publications

When purchasing tickets in advance, sports consumers are often faced with uncertainty. Most notably, in today's real-time environment, it can be challenging for consumers to determine how ticket prices and seat availability will change over time. Guided by the generic advanced-booking decision model, the current study investigated the role of time, ticket source (primary or secondary market), and team identification in advanced ticket purchasing by exploring a consumer's perceptions of ticket availability and finding a lower price. The results suggest the perceived likelihood of ticket availability and finding a lower priced ticket increased as the date of the game drew …

The Resiliency And Attitudes Skills Profile: An Assessment Of Factor Structure, Takeyra Williams, Edwin Gomez, Eddie Hill, Tammi Milliken, Jennifer Goff, Nicole Gregory

Human Movement Sciences & Special Education Faculty Publications

This study examines the Resiliency Attitudes and Skills Profile (RASP) in an afterschool recreation program with sixth grade students (N=137). The purpose of the study was to inspect the psychometric properties of the RASP and the internal consistency of the RASP global scale and subscales. This article expands on research reported on the RASP. Findings suggest that the RASP measures aspects of resiliency along four factors/dimensions. Suggestions for future research are provided.

Melatonin Supplementation Improves Glycemic Control While Lowering Oxidative Stress In Type 2 Diabetes, Carmine R. Grieco, Sheri R. Colberg, C. Thomas Somma, Andrew G. Thompson, Aaron I. Vinik

Human Movement Sciences & Special Education Faculty Publications

The purpose of this investigation was to evaluate the effect of melatonin on glycemic control and oxidative stress (OS) in adults with type 2 diabetes (T2D). Fourteen subjects with T2D (10 female, 4 male; 52.5 ± 5.0 years) were randomly assigned to melatonin (MEL) or placebo groups (PLA) for 42 days, in a crossover design. Subjects ingested 10 mg of MEL or an identical placebo (PLA) 30 minutes prior to sleep. Fasting blood draws occurred at baseline, 42 days, and 84 days. Plasma malondialdehyde, a marker of OS, significantly decreased on MEL (-6.25±2.10 nmol/ml) compared to PLA (0.72±3.30, p=0.028). The …

The Big Blue Test: Effects Of 14 Minutes Of Physical Activity On Blood Glucose Levels, Sheri R. Colberg, Manuel J. Hernandez

Human Movement Sciences & Special Education Faculty Publications

[First paragraph] For most with diabetes, physical activity has a blood glucose lowering effect (1). Hypoglycemia (i.e., blood glucose < 65 mg/dL) resulting from exercise is a concern, particularly for insulin users (2).

Blood Glucose Responses To Type, Intensity, Duration, And Timing Of Exercise, Sheri R. Colberg, Manuel J. Hernandez, Fatima Shahzad

Human Movement Sciences & Special Education Faculty Publications

[First Paragraph] The Big Blue Test (BBT) is an annual initiative by the Diabetes Hands Foundation to raise awareness of the importance of physical activity in managing diabetes. Individuals with diabetes voluntarily exercise and record self-monitored blood glucose levels. During the 2012 BBT, 5,157 diabetic participants (~90% insulin users) anonymously entered exercise type, intensity, duration, time elapsed since last meal, and blood glucose readings before and after one or more bouts of exercise separately through www.BigBlueTest.org or an Iphone app.

Development And Validation Of A Predictive Model Of Acute Glucose Response To Exercise In Individuals With Type 2 Diabetes, Bryan S. Gibson, Sheri R. Colberg, Paul Poirier, Denise Maria Martins Vancea, Jason Jones, Robin Marcus

Human Movement Sciences & Special Education Faculty Publications

Background: Our purpose was to develop and test a predictive model of the acute glucose response to exercise in individuals with type 2 diabetes.

Design and methods: Data from three previous exercise studies (56 subjects, 488 exercise sessions) were combined and used as a development dataset. A mixed-effects Least Absolute Shrinkage Selection Operator (LASSO) was used to select predictors among 12 potential predictors. Tests of the relative importance of each predictor were conducted using the Lindemann Merenda and Gold (LMG) algorithm. Model structure was tested using likelihood ratio tests. Model accuracy in the development dataset was assessed by leave-one-out cross-validation. …

Urban Adventure Racing: Using Grounded Theory To Assess Motives, Eddie Hill, Edwin Gómez, Brandi Brinkley, Marni Goldenberg

Human Movement Sciences & Special Education Faculty Publications

Although urban adventure races (ARs) have grown in popularity, little research exists on the reasons for the rising interest. Typically, adventure races are defined as a series of outdoor tasks completed within a given course or timeframe that are meant to challenge individuals, both mentally and physically. ARs borrow much from adventure programming. Aspects of AR programming may include goal-setting, problem-solving activities, and processing, and is often theoretically driven. This study used Grounded Theory as a basis for exploring why participants choose ARs, and if motives vary by gender. Of the 60 questionnaires collected, 40 were suitable for data analysis. …

Prescribing Physical Activity To Prevent And Manage Gestational Diabetes, Sheri R. Colberg, Kristin Castorino, Lois Jovanovič

Human Movement Sciences & Special Education Faculty Publications

Gestational diabetes mellitus (GDM) is the most prevalent metabolic disorder during pregnancy. Women diagnosed with GDM have a substantially greater risk of developing type 2 diabetes within 5-10 years after delivery, and the risk is increased by excess body weight. Uncontrolled hyperglycemia during pregnancy is potentially harmful to both mother and fetus, resulting in a greater need for Caesarian-section deliveries, delivery of larger infants with more excess body fat, a greater risk of infant death and stillbirth, and an elevated risk of infant hypoglycemia immediately after birth. Fortunately, engaging in physical activity prior to and during pregnancy may lower the …

The Effectiveness Of Prophylactic Ankle Braces In Reducing The Incidence Of Acute Ankle Injuries In Adolescent Athletes: A Critically Appraised Topic, Kelley E. Farwell, Cameron J. Powden, Meaghan R. Powell, Cailee W. Mccarty, Matthew C. Hoch

Human Movement Sciences & Special Education Faculty Publications

Clinical Scenario: Ankle injuries constitute a large number of injuries sustained by adolescent athletes participating in high school athletics. Prophylactic ankle bracing may be an effective and efficient method to reduce the incidence of ankle injuries in adolescent athletes in the secondary-school setting. Clinical Question: Do prophylactic ankle braces reduce the incidence of acute ankle injuries in adolescent athletes? Summary of Key Findings: Two of the three included studies reported that prophylactic ankle braces reduced the incidence of ankle injuries compared with no ankle bracing. Clinical Bottom Line: There is moderate evidence to support the use of prophylactic ankle braces …
