Effects Of Active Versus Passive Recovery On Blood Lactate And Performance In Repeated Wingate Tests, Madison Kirkpatrick

Cal Poly Humboldt theses and projects

The purpose of this study is to determine if an active recovery of a long duration at a moderate intensity or a passive recovery is more beneficial for subsequent anaerobic performance by tracking blood lactate and comparing anaerobic performance variables across Wingate tests. Currently, there is a lack of research on the effect of a longer duration active recovery protocol on blood lactate levels and power output in repeated Wingate tests as compared to passive recovery. A significant interaction was found between recovery and time for blood lactate (F = 6.935; p = 0.000). Blood Lactate levels were significantly …

Retrospective Analysis Of Contact Sport Participation On Cognitive Function In Healthy Athletes, Lisa C. Martinez

Cal Poly Humboldt theses and projects

This study explored the effects of contact and limited contact sport participation on neurocognitive function in non-concussed collegiate and adolescent athletes over time. Athletes participating in contact and limited contact sports have an increased risk of sustaining neurocognitive injuries, known as subconcussive blows, compared to non-contact sport athletes. We hypothesized that athletes participating in contact and limited contact sports, would exhibit a deficit in neurocognitive function following multiple seasons of play when compared to athletes participating in non-contact sports. Using a mixed repeated measures MANOVA statistical design, we analyzed computerized neurocognitive baseline ImPACT composite scores (verbal memory, visual memory, visual …

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 …

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.

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 …

Perceived Body Image And Reasons For Exercise Among College Students, Ileana Flores Delgado

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Ideal body image perceptions from Western culture has led body dissatisfaction levels to increase significantly in the past 30 years. Researchers have found that individuals tend to have inaccurate perceptions of their bodies. Therefore, comparisons between inaccurate perceptions and an ideal body image cause body dissatisfaction. Minimal research has been done focusing on the relation between body image and specific exercise behaviors. The purpose of this research is to understand how someone’s own body perception affects their exercise behavior, type and frequency. Specifically, does body perception affect the behaviors the individual demonstrates while exercising? Exercise behaviors may include decisions for …

Hemostatic Responses To Exercise In A Polycythemia Vera Patient, Allison M. Huschke

Senior Honors Projects, 2010-2019

PURPOSE: To assess the hemostatic responses to exercise in a patient with Polycythemia Vera (PV). METHODS: Six female runners (≥15 miles/week) completed a maximal treadmill test. One subject had PV while the other five subjects made up the comparison group. Blood samples were taken before and within two minutes after exercise. VO2max was also recorded. RESULTS: Pre-exercise Factor VIII and tPA-antigen were similar in the PV subject and comparison group. Factor VIII and tPA-antigen increased dramatically in the PV subject (+100%, +1000%) in relation to the comparison group (+22.9 ± 8.7%, +108 ± 78%) after exercise. Pre-exercise PAI-1 was lower …

The Hemostatic Effects Of Acute Exposure To Colored Cornstarch Powder During A 5k Run, Robert C. Allsbrook

Senior Honors Projects, 2010-2019

PURPOSE: To examine the acute hemostatic effects of particulate matter (PM) in the form of colored corn starch powder during a 5 kilometer race. METHODS: 10 recreationally active adults completed two 5k runs, one with color and one without color. 10 mL blood samples were taken 6 hours prior to the trial and immediately following the trial. PAI-1 activity, FVIII antigen, and tPA activity were measured using an ELISA. RESULTS: No significant main effects or interaction effects (P<0.05) were observed among any of the variables although a trend (P = 0.082) was observed for increased PAI-1 activity during exercise in the color condition. CONCLUSIONS: There is a trend towards increased PAI-1 activity levels during exercise during color runs that could be due to increased inflammation. Furthermore, the lack of increased FVIII:ag and tPA activity suggests that the intensity of the exercise may not have been adequate and further research should be conducted in this area.

A Comparison Of Multipath And Conventional Neuromuscular Electrical Stimulation, Cody Brian Bremner

Dissertations

Neuromuscular electrical stimulation (NMES) is the use of an electrical current for the purpose of eliciting a muscular response, and these treatments are most often used clinically for the specific purpose of increasing quadriceps strength. It is commonly accepted that the effectiveness of NMES for this purpose is primarily determined by the NMES training intensity. However, spatially limited motor unit recruitment, fatigue and discomfort negatively impact NMES-induced torque, which subsequently reduces NMES training intensities. Due to the importance of NMES training intensity, a substantial amount of research has focused on strategies designed to increase NMES-induced torque production, as well as …

Barriers, Motivations, And Preferences For Physical Activity Among Female African American Older Adults, Neha P. Gothe, Bradley J. Kendall

Kinesiology, Health and Sport Studies

According to the Centers for Disease Control and Prevention, less than 11% of adults more than the age of 65 meet the 2008 Physical Activity Guidelines for Americans. Among minority populations, only 5% of non-Hispanic Black older adults met the guidelines. Given our limited understanding of psychosocial and environmental factors that affect physical activity participation in these groups, the purpose of our focus groups was to investigate barriers, motivators, and preferences of physical activity for community-dwelling African American older adults. Three focus groups were conducted with female African American older adults (N = 20). Questions posed to each focus group …

Fast Way To Health, Angelika Ford

Scholars Week

A health issue that I am passionate about and wish to raise awareness about to make a difference in Murray is increase obesity due to food choices and low gym attendance. I would like to change the way people eat fast food. My first picture is a picture of the outside drive through at McDonald’s during lunch hour. I believe this is a barrier because there are many cars at the drive through order lanes. People are eating on the go; thus they are not spending time sitting down to enjoy the food they are consuming. This situation happens because …
