Slamming Dynamics Of Diving And Its Implications For Diving-Related Injuries, Anupam Pandey, Jisoo Yuk, Brian Chang, Frank E. Fish, Sunghwan Jung

Biology Faculty Publications

In nature, many animals dive into water at high speeds, e.g., humans dive from cliffs, birds plunge, and aquatic animals porpoise and breach. Diving provides opportunities for animals to find prey and escape from predators and is a source of great excitement for humans. However, diving from high platforms can cause severe injuries to a diver. In this study, we demonstrate how similarity in the morphology of diving fronts unifies the slamming force across diving animals and humans. By measuring a time-averaged impulse that increases linearly with the impact height, we are able to estimate the unsteady hydrodynamic forces that …

Peripheral Artery Disease Affects The Function Of The Legs Of Claudicating Patients In A Diffuse Manner Irrespective Of The Segment Of The Arterial Tree Primarily Involved, Todd Leutzinger, Panagiotis Koutakis, Matthew A. Fuglestad, Hafizur Rahman, Holly Despiegelaere, Mahdi Hassan, Molly Schieber, Jason Johanning, Nick Stergiou, G. Matthew Longo, George P. Casale, Sara A. Myers, Iraklis Pipinos

Journal Articles

Different levels of arterial occlusive disease (aortoiliac, femoropopliteal, multi-level disease) can produce claudication symptoms in different leg muscle groups (buttocks, thighs, calves) in patients with peripheral artery disease (PAD). We tested the hypothesis that different locations of occlusive disease uniquely affect the muscles of PAD legs and produce distinctive patterns in the way claudicating patients walk. Ninety-seven PAD patients and 35 healthy controls were recruited. PAD patients were categorized to aortoiliac, femoropopliteal and multi-level disease groups using computerized tomographic angiography. Subjects performed walking trials both pain-free and during claudication pain and joint kinematics, kinetics, and spatiotemporal parameters were calculated to …

Hip Torque Is A Mechanistic Link Between Sprint Acceleration And Maximum Velocity Performance: A Theoretical Perspective, Kenneth P. Clark, Laurence J. Ryan

Kinesiology Faculty Publications

Sprinting performance is critical for a variety of sports and competitive activities. Prior research has demonstrated correlations between the limits of initial acceleration and maximum velocity for athletes of different sprinting abilities. Our perspective is that hip torque is a mechanistic link between these performance limits. A theoretical framework is presented here that provides estimates of sprint acceleration capability based on thigh angular acceleration and hip torque during the swing phase while running at maximum velocity. Performance limits were calculated using basic anthropometric values (body mass and leg length) and maximum velocity kinematic values (contact time, thigh range of motion, …

Creating A Shared Musical Interpretation: Changes In Coordination Dynamics While Learning Unfamiliar Music Together, Emily A. Wood, Andrew Chang, Dan Bosnyak, Lucas Klein, Elger Baraku, Dobromir Dotov, Laurel Trainor

Journal Articles

The ability to coordinate with others is fundamental for humans to achieve shared goals. Often, harmonious interpersonal coordination requires learning, such as ensemble musicians rehearing together to synchronize their low-level timing and high-level aesthetic musical expressions. We investigated how the coordination dynamics of a professional string quartet changed as they learned unfamiliar pieces together across eight trials. During all trials, we recorded each musician's body sway motion data, and quantified the group's body sway similarity (cross-correlation) and information flow (Granger causality) on each trial. In line with our hypothesis, group similarity increased, while group information flow decreased significantly across trials. …

The Effects Of Vitamin D Supplementation On Athletic Performance And Injury Prevention, Amani Adeeb Abushamma

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Vitamin D supplementation has numerous effects on athletic performance and plays a significant role in preventing an athlete’s risk of getting injuries. Vitamin D has an impact on numerous physiological functions such as: bone health, muscle function, inflammatory response, and immune function. An athlete’s bone and muscle health are essential for maximum performance and career success. A bone fracture due to vitamin D deficiency can delay an athlete’s training and ultimately inhibit obtaining a collegiate scholarship and/or contract. A cross sectional study found that more than half of athletic trainers did not view 25-hydroxyvitamin D(25[OH]) testing and vitamin D supplementation …

The computer system times their reaction and movement time, and the test as a whole provides students with data to study the phenomenon of Contextual Interference. This system was previously controlled by an old computer setup that ultimately crashed. This project recreates the logic and user …

Bio-Inspired Propulsion: Towards Understanding The Role Of Pectoral Fin Kinematics In Manta-Like Swimming, Alec Menzer, Yuchen Gong, Frank E. Fish, Haibo Dong

Biology Faculty Publications

Through computational fluid dynamics (CFD) simulations of a model manta ray body, the hydrodynamic role of manta-like bioinspired flapping is investigated. The manta ray model motion is reconstructed from synchronized high-resolution videos of manta ray swimming. Rotation angles of the model skeletal joints are altered to scale the pitching and bending, resulting in eight models with different pectoral fin pitching and bending ratios. Simulations are performed using an in-house developed immersed boundary method-based numerical solver. Pectoral fin pitching ratio (PR) is found to have significant implications in the thrust and efficiency of the manta model. This occurs due to more …

The Effects Of Compression Garments And Extrinsic Visual Feedback On Single-Leg Balance Control, You-Jou Hung

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 3: Issue 1, Article 4, 2022. Single-leg balance control is very important in injury prevention (such as reducing the chance of falls and ankle sprains) and sport performance. Although compression garments (CGs) have been used for various purposes, it is unclear if wearing CGs can improve single-leg balance in healthy individuals. The purpose of the study was to examine if wearing CGs (pants) could enhance single-leg balance, and to compare the impact of wearing CGs on single-leg balance between conditions with and without extrinsic visual feedback. Twenty-five healthy individuals (aged 20-30 years) participated …

Reliability And Utility Of A Lumbopelvic-Hip Complex Stability Assessment In Individuals With Patellofemoral Pain, Erika Zambarano, Neal Glaviano, Amanda Murray

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE
Lumbopelvic-hip complex (LPHC) stability is related to altered movement patterns that are present in individuals with PFP. Current studies measuring LPHC function in PFP primarily assess endurance and not stability. A test of isolated LPHC stability, the Seated Trunk Control Test (STCT) was recently developed and test-retest reliability for the STCT has been shown to be excellent in a healthy population. To improve the clinical usefulness of the STCT, we aimed to establish test-retest reliability for individuals with PFP. We hypothesized the STCT would show good-to-excellent reliability. We also compared STCT performance between healthy individuals and those with PFP. …
