Impact of acute exercise on microRNAs related to concussion symptoms

Concussions, or traumatic brain injury (TBI), are a serious medical problem affecting approximately 1.7 million people in the United States each year. Current tools for analysis of concussion include the Glasgow Coma Scale, SCAT5, computerized topography (CT) and magnetic resonance imaging (MRI), however, these tools are typically not indicative of the range and severity of symptoms a patient may experience. Recent studies have explored the use of microRNAs as a biomarker for TBI severity in patients who have already experienced a TBI. We seek to investigate the microRNA levels in …

A Systematic Review: Long Range Correlations In Running Gait, Mr. Taylor Wilson

UNO Student Research and Creative Activity Fair

Long range correlations (LRCs) are apparent in human walking and running gait and are indicative of a healthy system. A systematic review (SR) was completed to determine the typical LRC patterns in running. 20 articles were included in the SR. LRCs in running gait tend to be similar to the LRCs in walking gait, with fatigue contributing to a negative effect on the LRCs.

This SR could have implications on training guidelines for coaches and physical therapy methods to increase the LRCs in running gait for healthier functioning. More research is needed to determine how LRCs depend on running surface …

This study aimed to address the differences in kinetic and kinematic parameters during countermovement jump motion with arm swing (AS) and no arm swing (NAS). We used OpenSim to examine the efficacy of AS in reducing the impulse applied to the body and changes in range of lower limb joint angles at landing instant. We calculated the maximum vertical peak of the ground reaction force and impulse generated at landing in two different …

Estimating Variations In Metabolic Cost Within The Stride Cycle During Level And Uphill Walking, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Indirect calorimetry provides the average cost of a stride cycle and prevents from identifying which part of the gait cycle causes increased metabolic cost in patients, however, recent simulation methods allow estimating the time profile of metabolic cost within the stride cycle. In this study, we compare the estimations of the time profile of the metabolic cost of two simulation methods for level and uphill walking. We used kinematic, kinetic and electromyography data from level and uphill walking (one participant) to estimate the time profiles of metabolic cost using the muscle-level metabolic model of Umberger using electromyography and kinematic data …

Halee Keller, Robert Shute, Dustin Slivka

University of Nebraska at Omaha, School of Health and Kinesiology, Omaha, NE

BACKGROUND: Mitochondria are highly concentrated in skeletal muscle tissue, and undergo damage from ROS during metabolic processes. This damage is often left unrepaired and leads to mitochondrial dysfunction, which has been linked to many common diseases. Exercise training increases mitochondrial development within skeletal muscle tissue and thus may be protective. Environmental temperature, when paired with exercise may provide an even greater effect than exercise alone. PURPOSE: The purpose of this study is to analyze the effects of three weeks of exercise …

The Energy Paradox Of The Ankle-Foot Complex During Human Walking, Nikolaos Papachatzis, Kota Takahashi

UNO Student Research and Creative Activity Fair

Flexor hallucis longus (FHL) is a multiarticular muscle that possesses the potential to alter foot’s functional and mechanical behavior, since it performs multiple significant functions during walking (e.g supports the medial longitudinal arch of the foot).The purpose of this study was to determine if the functional changes of the FHL are associated with the foot’s adaptations to the mechanical demands of walking. Backward walking is an experimental method capable of altering how the forces propagate underneath the foot and disrupting the mechanical function of the FHL muscle. We hypothesized that: (1) the muscle activity of the FHL will increase during …

Developing A Footswitch Device To Assess The Likelihood Of Falls In At-Risk Populations, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Falls are one of the major cause of injuries, reduced functioning and even mortality in older adults. Most of the falls occur during walking, so considering the mechanics of gait during walking can provide insight to identify the risk of fall in this population. A component of walking mechanics associated with falling in the elderly is gait variability (i.e. the inherent natural fluctuations between strides). Healthy states are associated with an optimal level of movement variability reflecting the adaptability of the underlying control system, while pathological gait can be either too regular, or periodic, or too random and disordered. In …

UNO Student Research and Creative Activity Fair

Patients with chronic obstructive pulmonary disease (COPD), suffer from deficits in their functional performance besides their lung disease. In this situation, increased muscle activity is needed to provide safe walking patterns, stability while walking. This increase in muscle activity leads to increased metabolic cost, i.e., using more oxygen to complete the task. The main objective of this study is to investigate the relationship between walking stability and metabolic cost in patients with COPD in comparison with age-matched controls. Seventeen patients with COPD and 23 healthy controls walked on a treadmill at three different speeds: preferred, fast (+20% preferred) and slow …
