Comparing acute effects of heavy resistance, plyometric, and complex training on post-activation performance enhancement in elite swimmers: a randomized controlled trial [PDF]
Frontiers in PhysiologyBackgroundPost-activation performance enhancement (PAPE) is an emerging strategy for optimizing pre-competition warm-up in elite swimming. However, substantial heterogeneity exists across studies due to inconsistent load standardization methodologies ...

Propulsive Performance of Morphing and Heaving Foil
Volume 5B: Ocean Engineering; Honoring Symposium for Professor Günther F. Clauss on Hydrodynamics and Ocean Engineering, 2022 Abstract Biological locomotion, observed in the flexible wings of birds and insects, bodies and fins of aquatic mammals and fishes, consists of their ability to morph the wings/fins. The morphing capability holds significance in the ability of fishes to swim upstream without spending too much energy and that of birds to glide for ...

On the performance of electrohydrodynamic propulsion [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013 Partially ionized fluids can gain net momentum under an electric field, as charged particles undergo momentum-transfer collisions with neutral molecules in a phenomenon termed an ionic wind. Electrohydrodynamic (EHD) thrusters generate thrust by using two or more electrodes to ionize the ambient fluid and create an electric field ...

Propulsion performance of a skeleton-strengthened fin [PDF]
Journal of Experimental Biology, 2008 SUMMARYWe examine numerically the performance of a thin foil reinforced by embedded rays resembling the caudal fins of many fishes. In our study, the supporting rays are depicted as nonlinear Euler–Bernoulli beams with three-dimensional deformability.

Propulsive performance of oscillating plates with time-periodic flexibility [PDF]
, 2023 We use small-amplitude inviscid theory to study the swimming performance of a flexible flapping plate with time-varying flexibility. The stiffness of the plate oscillates at twice the frequency of the kinematics in order to maintain a symmetric motion ...

Acoustic and propulsion performance facility [PDF]
The Journal of the Acoustical Society of America, 1974 A unique facility has been developed at the Lockheed-Georgia Company to evaluate, simultaneously, acoustic and propulsion performance characteristics of lift augmentation systems of the type considered for V/STOL aircraft. The facility is ideally suited for concept parametric and systematic noise-reduction investigations where the relationship between ...
