Acute Coffee Ingestion With And Without Medium-Chain Triglycerides Decreases Blood Oxidative Stress Markers And Increases Ketone Levels, Matthew J. Mcallister, Hunter S. Waldman, Liliana I. Renteria, Andrew E. Gonzalez, Matthew B. Butawan, Richard J. Bloomer

Kinesiology

Ingestion of ketone supplements, caffeine, and medium-chain triglycerides (MCTs) may all be effective strategies to increase blood levels of the ketone body beta-hydroxybutyrate (D-BHB). However, acute ingestion of a bolus of lipids may increase oxidative stress (OS). The purpose of the study was to investigate the impact of adding varying amounts of MCTs to coffee on blood levels of D-BHB and markers of OS.

The Association Of Cognitive Function Assessments Among Older Women, Anna Gookin

2020 Honors Symposium

Alzheimer’s disease (AD) is a loss of mental capabilities due to the slow degeneration of the brain and is the leading cause of dementia. Dementia is caused by the damage of neurons in the brain from diseases or injury, not only affecting mental abilities but also affecting daily activities.1 Every 65 seconds someone is diagnosed with AD and currently there is no known cure. Traditional cognitive testing is time consuming, expensive, can misdiagnose, and there is a lack of neuropsychologist. There is a need for a cognitive test that can provide an accurate, cheaper, and quicker result in order to …

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 …

Modular Footwear That Partially Offsets Downhill Or Uphill Grades Minimizes The Metabolic Cost Of Human Walking, Prokopios Antonellis, Cory M. Frederick, Arash Mohammadzadeh Gonabadi, Philippe Malcolm

Journal Articles

Walking on different grades becomes challenging on energetic and muscular levels compared to level walking. While it is not possible to eliminate the cost of raising or lowering the centre of mass (COM), it could be possible to minimize the cost of distal joints with shoes that offset downhill or uphill grades. We investigated the effects of shoe outsole geometry in 10 participants walking at 1 m s−1 on downhill, level and uphill grades. Level shoes minimized metabolic rate during level walking (Psecond-order effect < 0.001). However, shoes that entirely offset the (overall) treadmill grade did not minimize the metabolic rate of walking on grades: shoes with a +3° (upward) inclination minimized metabolic rate during downhill walking on a −6° grade, and shoes with a −3° (downward) inclination minimized metabolic rate during uphill walking on a +6° grade (P interaction effect = 0.023). Shoe inclination influenced (distal) ankle joint parameters, including soleus muscle activity, ankle moment and work rate, whereas treadmill grade influenced (whole-body) ground reaction force and COM work rate as well as (distal) ankle joint parameters including tibialis anterior and plantarflexor muscle activity, ankle moment and work rate. Similar modular footwear could be used to minimize joint loads or assist with walking on rolling terrain.

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) …

Is Postural Control During Unstable Sitting A Proxy Measure For Determinants Associated With Lumbar Stability?, Christian Larivière, Richard Preuss, Daniel Ludvig, Sharon M. Henry

Études primaires

Abstract

The aim of this study was to test whether determinants associated with lumbar stability can predict performance during unstable sitting (trunk postural control - TPC). If confirmed, unstable sitting could be viewed as a proxy measure for these determinants. Wobbling chair motion was measured in 58 subjects with an inertial sensor, and six outcomes were computed (mean frequency and velocity, frequency dispersion, two variables from the sway density analysis and Lyapunov exponent - short interval) to represent TPC performance. Subjects also performed five other trunk neuromuscular tests to quantify the thickness of back and abdominal muscles and …

Subject-Specific Regression Equations To Estimate Lower Spinal Loads During Symmetric And Asymmetric Static Lifting, F. Ghezelbash, A. Shirazi-Adl, Z. El Ouaaid, A. Plamondon, N. Arjmand

Études primaires

Workplace safety assessment, personalized treatment design and back pain prevention programs require accurate subject-specific estimation of spinal loads. Since no noninvasive method can directly estimate spinal loads, easy-to-use regression equations that are constructed based on the results of complex musculoskeletal models appear as viable alternatives. Thus, we aim to develop subject-specific regression equations of L4-L5 and L5-S1 shear and compression forces during various symmetric/asymmetric tasks using a nonlinear personalized finite element musculoskeletal trunk model. Kinematics and electromyography (EMG) activities of 19 young healthy subjects were collected during 64 different symmetric/asymmetric tasks. To investigate the reliability and accuracy of the musculoskeletal …

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 …

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, …

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 …

Sensory Integration And Its Role In Behavioral Plasticity In Children Diagnosed With Autism Spectrum Disorder, Clarissa Diaz

Open Access Theses & Dissertations

Although commonly characterized by communicative and social impairments, Autism Spectrum Disorder (ASD) presents a number of developmental deficits related to movement planning and action. The extent of these deficits to the entire neuromuscular system, as well as the individual input/output loops are still not well understood. Given the dynamic interplay between our plans, actions and outcomes lay the foundation for later mature motor behavior, it is critical to understand the unique motor learning processes these nervous systems face while a higher level of training plasticity may be present. A recent study examined the kinematics (acceleration, velocity, smoothness, etc.) of upper …

The Effect Of Curriculum- And Classroom-Based Physical Activity Breaks On Academic Performance In Elementary School Children In Southern New Mexico, Sephonnie S. Elliss

Open Access Theses & Dissertations

Research has provided strong evidence for the many health benefits of exercise (e.g. decreased risk of heart disease, diabetes, osteoporosis, sleep apnea, falls). Despite the plethora of evidence, most Americans do not meet the Surgeon General's recommendation of achieving 150 minutes of moderate-to-vigorous physical activity (PA) per week. Compounding the problem for children is the fact that although most American kids are enrolled in school for 30 or more hours per week, making schools a prime location to teach modes of physically active health habits, schools have instead increasingly become places that promote sedentary behavior as greater emphasis has been …

The Acute Effects Of Manual Resistance On Ballistic Bench Press Performance, Matthew Paul Gonzalez

Open Access Theses & Dissertations

Heavy conditioning activities (CA) during warm-ups has been found to improve subsequent movements. However, a problem with heavy CAs is the need for specialized equipment. Manual Resistance (MR) is accommodating resistance in which traditional exercises are replicated using resistance from a partner. This modality has led to improved muscular strength and endurance; however, the acute effects of MR have not been examined. Purpose: The purpose of this study was to determine if MR can lead to improvements in ballistic bench press (BBP) performance. Methods: Two subjects (age = 22.50 ± 0.71 years, weight = 97.88 ± 43.95 kg, BMI = …

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 …
