Kinesiology Faculty Publications

BACKGROUND: To avoid injuries in basketball players, they are recommended to pay more attention to improve their body balance. Therefore new training methods and equipment need to be devised. This study examined the effects of an 8-week basketball-specific proprioception training program while using a new developed one plane instability balance board during warm-up for improving balance ability in basketball players. Players who obtained basketball-specific balance training were compared to a control group. METHODS: Thirty-one male university basketball players (age: 21.35, SD = 0.605 years; height: 190.97, SD = 1.88; body mass: 86.95, SD = 2.61) participated in this study. Seventeen …

Inter-Segmental Coordination During A Unilateral 180° Jump In Elite Rugby Players: Implications For Prospective Identification Of Injuries, Kellen T. Krajewski, Carla Mccabe, Aaron M. Sinnott, Gavin L. Moir, Hugh S. Lamont, Susan Brown, Chris Connaboy

Kinesiology

Musculoskeletal injuries often occur during the execution of dynamic sporting tasks that involve rotation. The prescription of appropriate prevention strategies of musculoskeletal injury relies on assessments to identify risk, but current assessment tools focus on uniplanar movements. The purpose of this paper is to demonstrate the utility of the unilateral 180 jump as a potential assessment tool for injury risk in the lower body by (1) providing descriptive kinematics of the knee, thigh, and pelvis (2) conducting inter-segmental coordination analysis, and (3) comparing the knee kinematics between the dominant and non-dominant limb (NDL) during the loading (LOP) and landing phase …

Atv Dynamics And Pediatric Rider Safety, James T. Auxier Ii

Theses and Dissertations--Biomedical Engineering

It has been observed through numerous academic and governmental agency studies that pediatric all-terrain vehicle ridership carries significant risk of injury and death. While no doubt valuable to safety, the post-hoc approach employed in these studies does little to explain the why and how behind the risk factors. Furthermore, there has been no prolonged, widespread, organized, and concerted effort to reconstruct and catalog the details and causes of the large (20,000+) number of ATV-related injuries that occur each year as has been done for road-based motor vehicle accidents. This dissertation takes the opposite approach from a meta-analysis and instead examines …

Appetite-Regulating Hormones In Energy Compensation With Exercise, Jack Moreland

Theses and Dissertations--Nutrition and Food Systems

Background: The appetite-regulating hormones may influence compensatory increases in energy intake with exercise, although this causal relationship has been difficult to prove in a longitudinal trial.

Methods: 37 participants (29 female) aged 18 to 40 years performed aerobic exercise 6 days (6d), 2 days (2d), or 0 days per week for 12-weeks. Concentrations of ghrelin, leptin, glucagon-like peptide 1 (GLP-1), and insulin were assessed before (fasting, minute 0) and after a standardized meal at minute 15, 30, 45, 60, 90, 120, 150, and 180. Linear mixed-effects models were used to model the relationships between time point (12 weeks vs. baseline) …

Acute Physiological Responses To Arm-Cranking With Blood Flow Restriction, Benjamin Cockfield

Dissertations, Master's Theses and Master's Reports

Physiological responses to aerobic blood flow restriction exercise (BFR) are well documented for lower-body exercise but not upper-body exercise. I evaluated cardiorespiratory (heart rate, VO2, RER, ventilation), metabolic (tissue saturation, deoxyhemoglobin concentrations), and perceptual (effort, pain) responses to arm cranking with BFR at varying arterial occlusion pressures (AOP). Ten adults performed 4 intermittent arm cranking protocols (6x2-min, 1-min recovery): 1) low load (LL) – 40%VO2peak and 0% AOP; high load (HL) – 80%VO2peak and 0% AOP; (BFR50) – 40%VO2peak with 50% AOP; (BFR70) – 40%VO2peak with 70% AOP. Heart rate, RER, and ventilation, were higher with BFR compared to LL …

Exercise and Sport Studies: Faculty Publications

Background: A sensitive test reflecting subtle sensorimotor changes throughout disease progression independent of mobility impairment is currently lacking in progressive multiple sclerosis.

Objectives: We examined non-ambulatory measures of upper and lower extremity sensorimotor function that may reveal differences between relapsing–remitting and progressive forms of multiple sclerosis.

Methods: Cutaneous sensitivity, proprioception, central motor function and mobility were assessed in 32 relapsing–remitting and 31 progressive multiple sclerosis patients and 30 non-multiple sclerosis controls.

Results: Cutaneous sensation differed between relapsing–remitting and progressive multiple sclerosis at the foot and to a lesser extent the hand. Proprioception function in the upper but not the lower …

Reduced Frontopolar Brain Activation Characterizes Concussed Athletes With Balance Deficits, I. Helmich, J. Coenen, S. Henckert, E. Pardalis, S. Schupp, H. Lausberg

Exercise and Sport Studies: Faculty Publications

Objectives: Athletes with sport-related concussions (SRC) often demonstrate deficits in postural stability. Lower cerebral blood flow in frontal cortices has been documented in athletes with symptoms after SRC, however, it is unclear if functional brain oxygenation during postural control tasks is reduced in symptomatic athletes after SRC in the same manner. We therefore compared brain oxygenation patterns in frontal cortices of symptomatic and asymptomatic athletes with SRC during postural control tasks with the hypothesis that symptomatic athletes are characterized by reduced functional brain oxygenation during postural control. Methods: 62 concussed athletes (n = 31 symptomatic, n = 31 asymptomatic) were …

Anaerobic Capacity Measures In Healthy Active Adults Ages 18-29: Normative Reference Values And Differences Between Sex, Dylan E. Roberts

Cal Poly Humboldt theses and projects

The purpose of this study was to develop normative reference values for the modified Anaerobic Speed Test (mAST), an anaerobic capacity test that can be administered and completed on a commercial treadmill. The mAST of 15% grade has been created as one of the only protocols based on the original AST protocol of 20% grade. However, no percentile norms currently exist for this protocol, limiting its usefulness and interpretation of results. This paper presents normative values for active healthy adults ages 18-29, separated by sex. The sample consisted of 276 active healthy volunteers (161 men and 115 women). All mASTs …

Comparing Knee Joint Mechanics Across Phases Of The Menstrual Cycle, Bethany Kilpatrick

Cal Poly Humboldt theses and projects

Anterior cruciate ligament (ACL) injuries are among the most commonly occurring knee injury. Compared to men in the same sports, females are two to eight times at higher risk for ACL injury. Research suggests that hormone fluctuations across the menstrual cycle (MC) play a crucial role in ACL injuries due to their effect on tendons and ligament's mechanical properties. PURPOSE: To examine knee joint laxity during dynamic movements across three-time points of the MC. METHODS: Seven young, healthy females with regular MCs performed three jump-landing tasks (double leg depth jump, single-leg lateral jump, and single-leg forward jump) across the early-follicular, …

Association Of Various Physiological And Fitness Markers To Body Fat Percentage In Physically Inactive Adults, Anthony Mckee

Graduate Research Theses & Dissertations

Obesity can dramatically and negatively affect many aspects of normal physiological functioning. Obesity is defined as abnormal or excessive body fat accumulation that presents a risk to health. Body mass index (BMI) is a widely used approach to quantify body fat in large group settings; however, this method has significant shortcomings with accuracy and estimation. More direct measures such as bioelectrical impedance analysis (BIA) can provide a more reliable and accurate assessment of body fat mass and, therefore reduce the shortcomings of BMI when assessing possible associations with health- and performance-related variables. A plethora of research studies has been conducted …

Biomechanical Comparison Of "Old" And "New" Cheer Shoes In Collegiate Cheerleaders, Abigail C. Johnson

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: The sport of cheerleading requires that athletes perform with a high degree of flexibility, strength, endurance, and balance. The leading injury in cheerleading is a lateral, inversion, ankle sprain. As footwear serves as an interface between the foot and the surrounding environment, characteristics of shoes should be monitored to determine the effects on proprioceptive communication. No previous literature was found that examined the biomechanical differences between “Old” and “New” shoes in collegiate cheerleaders. PURPOSE: The purpose of this study was to examine the biomechanical differences exhibited by collegiate cheerleaders while performing balance testing and step-down, landing tasks in “old” …

A Comparative Assessement Of Discrete And Reciprocal Design In Children With Autism Spectrum Disorder, Jallycia Rene Pearson

Open Access Theses & Dissertations

Although typically diagnosed through social impairment and repetitive stereotypical behavior, recent work in the last decade has shown motor irregularities across the autism spectrum. With regard to upper extremity coordination, studies have agreed that children on the Autism spectrum present overall decreased performance compared to their neurotypical peers but fail to find commonality on the locus of this error. For example, studies have highlighted reaction time, arm trajectory as well as corrective sub-movements as areas in need of improvement. One possible reason for the conflicting results could be related to the nature of the task employed, e.g. discrete vs reciprocal …
