PRC-Affiliated Research
Aquatic therapy for rehabilitation can be performed in a variety of environments, which can vary from a traditional swimming pool to a self-contained underwater treadmill. While kinematic analysis has been performed in large volume swimming pools using specific underwater motion capture systems, researchers may only have access to a land-based motion-capture system, which is not waterproof. Additionally, underwater motion capture systems may not fit within the confines of a smaller underwater treadmill. Thus, the purpose of this study was to design and analyze methodology to quantify lower limb kinematics during an aquatic treadmill session, using a land-based motion capture system. …

Effects Of Flight Altitude On The Lift Generation Of Monarch Butterflies: From Sea Level To Overwintering Mountain, Madhu K. Sridhar, Chang-Kwon Kang, Brian D. Landrum, Hikaru Aono, Shannon L. Mathis, Taeyoung Lee
PRC-Affiliated Research
Aerodynamic efficiency behind the annual migration of monarch butterflies, the longest among insects, is an unsolved mystery. Monarchs migrate 4000 km at high-altitudes to their overwintering mountains in Central Mexico. The air is thinner at higher altitudes, yielding reduced aerodynamic drag and enhanced range. However, the lift is also expected to reduce in lower density conditions. To investigate the ability of monarchs to produce sufficient lift to fly in thinner air, we measured the climbing motion of freely flying monarchs in high-altitude conditions. An optical method was used to track the flapping wing and body motions inside a large pressure …
Alternative Upper Configurations During Agility-Based Movements: Part 1, Biomechanical Performance, Bradley S. Davidson, Kevin B. Shelburne, Moira Pyrhoda, Rachel Wathen, Nick Nelson, Sean Higinbotham, Jay Dicharry, Daniel Feeney, Kate Harrison
Alternative Upper Configurations During Agility-Based Movements: Part 1, Biomechanical Performance, Bradley S. Davidson, Kevin B. Shelburne, Moira Pyrhoda, Rachel Wathen, Nick Nelson, Sean Higinbotham, Jay Dicharry, Daniel Feeney, Kate Harrison
Alternative Upper Configurations During Agility-Based Movements
The objective of this research was to determine if three alternative shoe closures improve biomechanical performance measures compared to a standard lace closure in agility-based movements. NCAA Division 1 and club-level male athletes recruited from lacrosse, soccer, tennis, and rugby performed four court-based movements: Lateral Skater Jump Repeats (LSJ), Countermovement Jump Repeats (CMJ), Triangle Drop Step Drill (TDS), and Anterior-Posterior Drill (AP). Each athlete performed the movements in four shoe upper closures: Standard Closure, Lace Replacement, Y Wrap, and Tri Panel. Movement completion time, Ground contact time, peak eccentric rate of force development (RFD), peak concentric GRF, peak concentric COM …

Static Accuracy Analysis Of Vicon T40s Motion Capture Cameras Arranged Externally For Motion Capture In Constrained Aquatic Environments, Shreyas L. Raghu, Chang-Kwon Kang, Paul Whitehead, Akifumi Takeyama, Ryan Conners
PRC-Affiliated Research
While the capabilities of land-based motion capture systems in biomechanical applications have been previously reported, the possibility of using motion tracking systems externally to reconstruct markers submerged inside an aquatic environment has been under explored. This study assesses the ability of a motion capture system (Vicon T40s) arranged externally to track a retro-reflective marker inside a glass tank filled with water and without water. The reflective tape used for marker creation in this study was of Safety of Life at Sea (SOLAS) grade as the conventional marker loses its reflective properties when submerged. The overall trueness calculated based on the …

A Numerical Analysis Of The Effects Of Wing Kinematics On Flapping Wing Aeroacoustics, Kabilan Nedunchezian, Chang-Kwon Kang, Hikaru Aono
A Numerical Analysis Of The Effects Of Wing Kinematics On Flapping Wing Aeroacoustics, Kabilan Nedunchezian, Chang-Kwon Kang, Hikaru Aono
PRC-Affiliated Research
Despite the recent interest in flapping wing aerodynamics, the aerodynamic sound generation mechanism of a flapping wing is inadequately understood. In this paper, the interplay between the wing motion, resulting unsteady aerodynamics, and aeroacoustics of a flapping wing flyer is investigated. The wing motion is varied in terms of the flapping amplitude, pitching amplitude, and the phase difference between flap and pitch. The unsteady flow around the flapping wing is numerically calculated using a well-validated Navier-Stokes equation solver. Acoustic pressures are computed using the Ffowcs-Williams-Hawkings equation in a three-dimensional space at varying distances from the wing. Two main sound generation …
