Developing A Pricing Strategy For The Los Angeles Dodgers, Denise Linda Parris, Joris Drayer, Stephen L. Shapiro

Human Movement Sciences & Special Education Faculty Publications

In 2011, the Los Angeles Dodgers Stadium averaged 36,236 fans per game, dropping from 43,979 in 2010 and 46,440 in 2009, an overall loss of about 10,000 fans per game in just two years. In 2011, The Dodgers' attendance ranking fell from first to eleventh in Major League Baseball (MLB), which amounted to a loss of over 800,000 tickets sold per year, as well as the resulting revenue from concessions and parking. Despite the Dodgers' long and storied history, ticket demand had been negatively influenced by inconsistent performance, mounting bad publicity surrounding owner Frank McCourt's divorce, the beating of a …

Dynamic Ticket Pricing In Sport: An Agenda For Research And Practice, Joris Drayer, Stephen L. Shapiro, Seoki Lee

Human Movement Sciences & Special Education Faculty Publications

For decades, the airline and hotel industries have regularly changed prices to keep pace with fluctuating levels of consumer demand. This demand-based approach to pricing is referred to as revenue management. Meanwhile, the sport industry has traditionally underpriced tickets using a cost-based approach in order to maximize attendance and promote fan satisfaction. However, as operating costs have grown, sport organizations are now forced to reconsider these conservative pricing practices. Subsequently, in 2009, the San Francisco Giants were the first team to utilize dynamic pricing, which is a strategy that mirrors the revenue management approach. While data supporting or refuting the …

Plantar Vibrotactile Detection Deficits In Adults With Chronic Ankle Instability, Matthew C. Hoch, Patrick O. Mckeon, Richard D. Andreatta

Human Movement Sciences & Special Education Faculty Publications

Purpose: The purpose of this study was to investigate the vibrotactile detection thresholds of the plantar cutaneous afferents in subjects with chronic ankle instability compared with healthy control subjects. Methods: Eight adults with chronic ankle instability and eight adults with no ankle sprain history participated. Vibrotactile detection thresholds were assessed using a mechanical stimulus generator system, mounted onto an articulated microscope arm, which delivered sinusoidal vibrotactile inputs to the foot sole at three different sites: head of the first metatarsal, base of the fifth metatarsal, and the heel. Vibrotactile stimulation was delivered at a range of test frequencies that corresponded …

Upper Extremity Strength Characteristics In Female Recreational Tennis Players With And Without Lateral Epicondylalgia, Ann M. Lucado, Morey J. Kolber, M. Samuel Cheng, John L. Echternach Sr.

Rehabilitation Sciences Faculty Publications

STUDY DESIGN: Descriptive, cross-sectional.

OBJECTIVES: To compare static strength characteristics of the upper extremity musculature in female recreational tennis players with lateral epicondylalgia to those of nonsymptomatic tennis players and a control group of women who did not play tennis.

BACKGROUND: There is a paucity of research describing the relationship between lateral epicondylalgia and strength characteristics of the upper extremity musculature, despite the functional relationship between the shoulder, elbow, and wrist.

METHODS: Sixty-three women were recruited into 3 groups (n = 21 per group): symptomatic tennis players (SIP) with lateral epicondylalgia, nonsymptomatic tennis players, and controls. Data collection was performed …

Influence Of Personal And Lesson Factors On Caloric Expenditure In Physical Education, Ang Chen, Haichun Sun, Xihe Zhu, Catherine D. Ennis

Human Movement Sciences & Special Education Faculty Publications

Background: Increasing caloric expenditure in physical education is considered an effective school-based approach to addressing the child obesity epidemic. This study was designed to determine synergistic influences of student characteristics and lesson factors on caloric expenditure in elementary and middle school physical education.

Methods: The study used a multi-level design. Level-1 factors included personal characteristics: age, gender, and body mass index. Level-2 factors included lesson length, content, and school level. Based on the Center for Disease Control and Prevention age-gender adjusted growth chart, students in 87 classes from 14 elementary and 15 middle schools were pre-screened into "Overweight", "Healthy weight", …

A Functional Agility Short-Term Fatigue Protocol Changes Lower Extremity Mechanics, Nelson Cortes, David Quammen, Shawn Lucci, Eric Greska, James Onate

Human Movement Sciences & Special Education Faculty Publications

The purpose of this study was to evaluate the effects of a functional agility fatigue protocol on lower extremity biomechanics between two unanticipated tasks (stop-jump and sidestep). The subjects consisted of fifteen female collegiate soccer athletes (19 ± 0.7 years, 1.67 ± 0.1 m, 61.7± 8 kg) free of lower extremity injury. Participants performed five trials of stop-jump and sidestep tasks. A functional short-term agility protocol was performed, and immediately following participants repeated the unanticipated running tasks. Lower extremity kinematic and kinetic values were obtained pre and post fatigue. Repeated measures analyses of variance were conducted for each dependent variable …

Fitness, Fatness, And Metformin Response, Corey A. Rynders

Human Movement Sciences & Special Education Faculty Publications

We appreciate the comments of Dr. Falk and Mr. Dotan and would like to respond to their concerns. As we indicate in the discussion of our article (1), we realize that changes in maturation and body composition can affect the assessment of VO_2max. However, we do not feel that the change in VO_2peak observed in the subjects that improved VO_2peak was primarily related to a reduction in body weight.

The Effectiveness Of Injury-Prevention Programs In Reducing The Incidence Of Anterior Cruciate Ligament Sprains In Adolescent Athletes, Jeffrey Paszkewicz, Tristen Webb, Brian Waters, Cailee Welch Mccarty, Bonnie Van Lunen

Human Movement Sciences & Special Education Faculty Publications

Clinical Scenario: There is a high incidence of anterior cruciate ligament (ACL) injury in adolescents participating in pivoting sports such as soccer, basketball, and handball. Most ACL injuries in athletes are noncontact injuries, with a mechanism of sudden deceleration, change in direction, or landing from a jump. These mechanisms coupled with an increase in contraction of the quadriceps have been shown as risk factors for ACL injuries. Injuries to the ACL may require surgery, a long rehabilitation, and the potential for reinjury. Studies have shown reductions in lower extremity injury rates using training protocols that focus on landing mechanics, balance …

Landing Technique Affects Knee Loading And Position During Athletic Tasks, Nelson Cortes, Steven Morrison, Bonnie L. Van Lunen, James A. Onate

Rehabilitation Sciences Faculty Publications

Anterior cruciate ligament (ACL) injuries have been reported to occur with the ankle in a dorsiflexed position at initial contact. Few studies have attempted to quantify the biomechanical parameters related with such landing patterns during athletic tasks.

Objectives- The purpose of this study was to evaluate the effects that two landing techniques have in lower extremity biomechanics while performing two tasks.

Design- Single-group repeated measures design.

Methods- Twenty female soccer athletes from a Division 1 institution performed two landing techniques (forefoot and rearfoot) during two unanticipated tasks (sidestep cutting and pivot). Repeated measures analyses of variance were conducted to assess …
