The Implication Of Title Ix Legislation On Women’S Athletics At Brigham Young University, Daniel C. Swinton, Barbara Lockhart

Journal of Undergraduate Research

Title IX of the Education Amendments of 1972 has helped educational institutions throughout the country draw closer to gender equity in all facets of education. Much of Title IX is accepted and praised, but a hotly debated area having to do with interpreting and implementing the law, is intercollegiate athletics. The court’s interpretations require proportionality and progress in complying with Title IX and many schools — in fact, the vast majority — continue to struggle to meet the law’s demands. Brigham Young University is among them and in the past ten years, the school’s athletic department has undergone a number …

Assessing Current Awareness And Behaviors Of Those At Risk For Multiple Sclerosis, Kristin A. Prusse, Dr. Michael Barnes

Journal of Undergraduate Research

Multiple Sclerosis (MS) is an inflammatory autoimmune disorder of the central nervous system. Multiple sclerosis is characterized by the destruction of the myelin sheath, which surrounds and insulates the nerve fibers in the brain and spinal cord. This destruction forms plaques of damaged tissue in the brain causing nerve impulses to be slowed or halted. MS is now the most common cause of neurological disability in young adults. However, in many cases, this disease goes misdiagnosed for several years, which delays treatments that can help manage symptoms and slow the progression of the disease. It then becomes important for those …

Single Fiber Myosin Heavy Chain Response To Eight Weeks Of Sprint Cycle Training, Nathan Miller, Dr. Allen Parcell

Journal of Undergraduate Research

Research has given us an increased understanding of skeletal muscle. We have learned that skeletal muscle function is influenced by neural, biochemical, molecular, and biomechanical factors. As our understanding of these factors increases so does our ability to facilitate positive adaptations in muscle function.

Self-Optimization Of Stride Length In Uphill Running, Erin K. Nasson, Dr. Iain Hunter

Journal of Undergraduate Research

The economy of running is very important to both competitive and recreational runners. A runner wants to perform as economically as possible to minimize metabolic costs and in order to do this the running technique must be optimized. To minimize metabolic costs refers to ones oxygen uptake, which is the amount of oxygen that is consumed throughout an activity. When large amounts of oxygen are used, the athlete will fatigue in a shorter amount of time so by minimizing the oxygen uptake, one will be able to increase the time to fatigue. Optimizing technique is something that we all do …

The Effect Of Diathermy And Stretch On The Flexibility Of The Hamstring In A Population Of 48.4 + 12.3 Years, Sheldon Knight, Dr. Brent Feland

Journal of Undergraduate Research

Many studies have compared the different variable of stretching: duration of stretch, intensity of stretch, method, frequency, and modalities with stretch (i.e. heat and or cold). Stretching has been shown to improve flexibility, or increase range of motion, injury prevention, enhance muscle performance, promotion of healing, and possibly decreased symptoms of delayed onset muscle soreness, and improved running economy. Modalities—heat and or cold—combined with stretch have provided varied results with flexibility. Heat with stretching may or may not provide adequate results. In some studies, cold with stretch was found to be more beneficial than heat with stretch. Few studies have …

Identifying Barriers To Patient Recruitment In Community Randomized Clinical Trials, Evan L. Thacker, Dr. Ray M. Merrill

Journal of Undergraduate Research

Randomized clinical trials (RCTs) are the final testing phase for new medical procedures or treatments in human subjects. A common problem in community-based RCTs is low participation. Researchers have sought to identify barriers to RCT recruitment by measuring knowledge and attitudes about RCTs. Most studies focus on subjects already involved in clinical trials or subjects who were invited to participate in clinical trials but declined. Our research addresses recruitment barriers in a broader context, by studying knowledge and attitudes among the general public, including individuals who have never participated in a RCT.

Is an electric hot pad as effective as a hydrocollator pack in heating tissue?

Degeneracy And Long-Range Correlations, D. Delignières, Vivien Marmelat

Journal Articles

Degeneracy is a ubiquitous property of complex adaptive systems, which refers to the ability of structurally different components to perform the same function in some conditions and different functions in other conditions. Here, we suppose a causal link between the level of degeneracy in the system and the strength of long-range correlations in its behavior. In a numerical experiment, we manipulated degeneracy through the number of networks available in a model composed of a chain of correlated networks over which a series of random jumps are performed. Results showed that correlations in the outcome series increased with the number of …

Speed Is Relative (Human And Animal Running Speeds): Are You A Cheetah, A Chicken, Or A Snail?, Chad E. Buckley

Faculty and Staff Publications – Milner Library

To put matters in perspective, running speeds for humans and other land animals are compared over various distances. Humans compare quite favorably over longer distances with many species. Both fast and slow human runners can benefit from comparing their individual times in races with other species.

Correlation Of Shoulder And Elbow Kinetics With Ball Velocity In College Baseball Pitchers, Eric Post

Theses and Dissertations

Specific injuries at the elbow and glenohumeral joints have been linked to several kinetic variables that occur throughout the throwing motion. Ulnar collateral ligament (UCL) sprains have been linked to excessive elbow valgus and shoulder external rotation torques occurring during the late-cocking phase of throwing. Shoulder external rotation torque during the late arm-cocking phase and shoulder distraction forces during the deceleration phase contribute to tears of the labrum. Additionally, it is believed that the peak distraction force generated during the arm deceleration phase also contributes to SLAP tears and rotator cuff pathologies. Very little research has been done to directly …

The Effect Of Prior Knowledge Of Pain Rating And Socialization On Habituation To Cold-Induced Pain, Brady Whetten, Dr. Ken Knight

Journal of Undergraduate Research

Cryokinetics is a popular tool for rehabilitating acute joint sprains. It involves numbing the limb with ice water immersion, followed by active exercise, repeated for a total of five bouts (8). The major limitation of this therapy is that the cold immersion necessary to induce numbness is quite painful during the initial immersion. Clinical experience shows that the sensation of pain decreases after repeated bouts. Research to confirm this observation, however, has shown either no habituation (6) or a slower rate of habituation (7) than indicated by clinical observation.

The Effects Of Game Size On The Physical Activity Levels And Ball Touches Of Elementary School Children In Physical Education, Kenneth Bell, Tyler G. Johnson, Jane Shimon, John Bale

Kinesiology Faculty Publications and Presentations

The purpose of this study was to determine the impact of participating in small (3v3), medium (6v6), and large-sided (12v12) games on the physical activity levels (pedometer step counts, accelerometer counts, and minutes of moderate-to-vigorous physical activity) and ball touches of children in physical education class. Participants were 29 students (55% boys and 45% girls) age 10-11 yrs. All participants wore a Yamax SW-200 pedometer and had their ball touches monitored and recorded. Twelve participants also wore an ActiGraph GT3X accelerometer. Repeated measure ANOVAs were computed to test for significant differences for each dependant variable with corresponding post hoc tests. …

The Effects Of Functional Fatigue On Ground Reaction Forces Of A Jump, Land, And Cut Task, Mikaela Boham, Mark Debeliso, Chad Harris, Ronald Pfeiffer, John Mcchesney, Joseph M. Berning

Kinesiology Faculty Publications and Presentations

Rapid acceleration, deceleration, landing and change of direction have been implicated as mechanisms of noncontact anterior cruciate ligament (ACL) injury. PURPOSE: To examine the ground reaction forces occurring to the knee during non-fatigued and fatigued jump, land and cut maneuvers in three unplanned cutting directions. METHODS: Eleven healthy, adult female collegiate soccer athletes participated in this study (age= 20.3±0.9 years; height= 167.4±4.8 cm; mass= 63.7±7.7 kg). Each subject was instructed to perform 9 jump, land, and cut maneuvers in a pre-fatigued state and fatigued state. The protocols were randomly assigned to include 3 cuts in each of the three directions. …

Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes

Mechanical and Aerospace Engineering Faculty Publications

The human body has more muscles than Degrees of Freedom (DoF), and that leads to indeterminacy in the muscle force calculation. This study proposes the formulation of an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis. The originality of that formulation consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated. Two approaches have been considered. In Approach A, measured contact forces are applied to the model and all inverse dynamics loads are matched in order to get a physiological calibration of muscle parameters. …

Strength, But Not Direction, Of Handedness Is Related To Height, Ruth E. Propper, Tad T. Brunyé, Karly Frank, Sean E. Mcgraw

Department of Psychology Faculty Scholarship and Creative Works

Left-handers are reputed to be shorter than right-handers. However, previous research has confounded handedness direction (left- versus right-handedness) with handedness strength (consistency with which one hand is chosen across a variety of tasks; consistent- versus inconsistent-handedness). Here, we support a relationship between handedness strength, but not direction, and stature, with increasing inconsistent-handedness associated with increasing self-reported height.

Comparison Of The Effect Of Caffeine Ingestion On Time To Exhaustion Between Endurance Trained And Untrained Men, Steven Porterfield, Jon Linderman, Lloyd L. Laubach, Corinne M. Daprano

Health and Sport Science Faculty Publications

This study compared the ergogenic effects of caffeine on men who were endurance trained to those who were untrained. The study was a double-blind, placebo-controlled crossover experimental design. Ten endurance trained men (mean age 24.4 ± 2.0 yrs, weight 79.4 ± 8.5 kg, predicted VO2 max 46.3 ± 1.8 mL·kg-1·min-1) and 10 untrained men (mean age 22.8 ± 1.9 yrs, weight 88.9 ± 9.9 kg, predicted VO2 max 37.6 ± 2.7 mL·kg-1·min-1) completed two cycle ergometer trials to exhaustion at 80% of their predicted workload max 30 min after ingesting either 5 mg·kg-1 of body weight of caffeine or a …

The Relationship Between Subjectively Motivational Music And Various Exercise Variables While Running At Maximal Speed, Michael Maloney

Honors College Theses

Purpose: To determine whether there are differences in steps/min/m, highest achieved exercise heart rate, average exercise heart rate, average running speed, estimated relative VO2, and RPE, while listening to subjectively motivating music, as compared to non-motivating music, while running at max speed. Methods: Eleven students enrolled at the University of Massachusetts Boston, considered “non-runners” from 19 to 34 years of age, ran at max speeds for 12-15 minutes, once while listening to a play-list of songs they ranked most motivating, and a second time on a separate day, while listening to a play-list of songs they ranked least …
