Lower Body Gait Variability As A Distinguishing Feature In Humans, Tyler M. Wiles, Seung Kyeom Kim, Nick Stergiou, Aaron D. Likens

UNO Student Research and Creative Activity Fair

Most humans have a fingerprint that is unique and persists throughout life. The same may be true for gait. Each person is unique physiologically and biomechanically, and has experienced a unique progression of life including injuries, habits, hobbies, or lifestyles that all contribute to navigating the world. Those individualized experiences, whether intended or not, are potentially on display in gait. We hypothesized that there are gait characteristics intrinsic and unique to everyone, so that everyone has a unique “gaitprint”, similar to humans possessing unique fingerprints. To test our hypothesis, we recruited thirty healthy young adults between the ages 19-35 as …

Walking with a Load on Wheels: Potential Effects of Bidirectional Springs on Walking Economy

Have you ever noticed how your arms alternatively flex and extend when pushing a heavy shopping cart? Accelerating and decelerating heavy masses, such as a shopping cart, can require much effort. During walking, we alternatively accelerate and decelerate our Center of Mass (COM) in every gait cycle, which can require even more effort if we accelerate and decelerate a load while walking. Theoretically, this effort can be reduced by timing the acceleration and deceleration of the load's mass opposite to the individual's COM. Previous studies have …

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 3, 2024. The rugby codes (i.e., rugby union, rugby league, rugby sevens [termed ‘rugby’]) are team-sports that impose complex physical demands upon players which in-turn, leads to domain-specific fatigue (e.g., neuromuscular, cardio-autonomic). Quantifying post-match fatigue through various methods and metrics is important to monitor player fatigue status, which influences training readiness. The specific and general barriers limiting the use of post-match fatigue monitoring in rugby are not presently known. Therefore, the aims of this study were to identify specific and general barriers (clusters of specific barriers) to the use …

Thrust Production And Chordal Flexion Of The Flukes Of Bottlenose Dolphins Performing Tail Stands At Different Efforts, David Kramer, Maura J. Sheehan, Frank E. Fish

Biology Faculty Publications

Dolphins have become famous for their ability to perform a wide variety of athletic and acrobatic behaviors including high-speed swimming, maneuverability, porpoising and tail stands. Tail stands are a behavior where part of the body is held vertically above the water's surface, achieved through thrust produced by horizontal tail fluke oscillations. Strong, efficient propulsors are needed to generate the force required to support the dolphin's body weight, exhibiting chordwise and spanwise flexibility throughout the stroke cycle. To determine how thrust production, fluke flexibility and tail stroke kinematics vary with effort, six adult bottlenose dolphins (Tursiops truncatus) were tested at three …

Assessing The Effectiveness Of Goal-Directed Versus Stimulus Driven Visual Search Training At Improving Goalkeepers’ Penalty Kick Save Responses, Annabelle Treacy

Theses, Dissertations and Capstones

Goalkeepers must perceive and analyze many different types of information in a short time to effectively move their bodies to make a save. Skilled goalkeepers enhance their actions by coupling them to information present in their environment. The information in their environment constantly changes, so the goalkeepers must adjust their strategies or positions to match the environmental demands. Goalkeepers use two types of perception and attentional strategies: stimulus-driven and goal-directed. Stimulus-driven perception is fast and compulsory, while goal-directed perception is slower and more methodical. Both visual search strategies direct the goalkeeper’s attention to where it is most needed and can …

The Effect Of Repetitive Sub-Concussive Head Impacts In A Rodent Model And Its Implication In Contact Sports, Jay Venkatraman

Wayne State University Dissertations

Traumatic Brain Injury (TBI) is the damage caused to the brain by an external force causing rapid acceleration and deceleration of the brain, and a sub-concussive impact is defined as a bump, blow or jolt to the head not resulting in any apparent symptoms. Within the United States, around 1.7 million people suffer from TBI, of which sports-related injuries are the cause for one-third of the head injuries. It is estimated that approximately 20% of professional boxers experience at least one incidence of concussion or knockout in their careers and 40% of retired boxers suffer from lasting effects ranging from …

Connaître la distribution de ces forces internes lors d’activités de travail est nécessaire autant en prévention qu’en réadaptation des travailleurs. La modélisation musculosquelettique (MS) de la colonne vertébrale est la seule approche non invasive permettant d’estimer les charges sur les structures internes de la colonne.

Deux modèles ont été développés au Québec, soient un modèle par éléments finis (MEF) guidé par le mouvement et un autre guidé par des mesures électromyographiques (EMG) d’activation musculaire (modèle MEMG). Ces modèles sont donc sensibles …

Hamstring And Quadriceps Activation During Single Leg Hopping At Varying Frequencies: Electromyography Analysis, Jemma Bosselman

Scripps Senior Theses

Identification of knee motor control strategy is salient both for biomechanical understanding of the lower limb and for medical applications. Integral to knee function are the quadriceps and hamstring, an antagonistic muscle pair. Sub-optimal relative activation of the pair can increase injury potential. Muscle activation patterns are largely activity specific, necessitating muscle control research across various tasks. Single leg hopping has been sparsely studied, particularly for muscle activation in relation to hopping frequency. This project thus aimed to determine the effect of single leg hopping frequency on quadriceps and hamstring activation using surface electromyography (EMG), with the vastus lateralis (VL) …
