Article Abstract
Chen, Z-R, Peng, H-T, Siao, S-W, Hou, Y-T, and Wang, L-I. Whole body vibration immediately decreases lower extremity loading during the drop jump. J Strength Cond Res 30(9): 2476-2481, 2016-The purpose of this study was to evaluate the acute effect of whole body vibration (WBV) on lower extremity loading during the drop jump (DJ). Fifteen male collegiate physical education students randomly completed 3 experimental sessions on 3 separate days with 4 days interval between sessions (performing 3 trials of DJ from 30-, 40-, and 50-cm drop heights before WBV and 4 minutes after WBV). Eight cameras and 2 force platforms were used to record kinematic and kinetic data, respectively. Peak impact force and loading rate significantly decreased after WBV during DJ from 40 and 50 cm. Knee angular displacements significantly increased after WBV during DJ from 30, 40, and 50 cm. Whole body vibration may help immediately reduce lower extremity loading.

Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are common respiratory conditions that significantly impact patient health and contribute to substantial healthcare burdens. While conventional treatments offer symptom relief, many patients continue to experience persistent symptoms, side effects, or resistance to standard therapies. This highlights the growing need for novel, non-invasive, and sustainable therapeutic strategies to manage chronic airway inflammation.

Harbor seals possess a remarkable ability to detect hydrodynamic footprints left by moving objects, even long after the objects have passed, through interactions between wake flows and their uniquely shaped whiskers. While the flow-induced vibration (FIV) of harbor seal whisker models has been extensively studied, their response to unsteady wakes generated by upstream moving bodies remains poorly understood. This study investigates the wake-induced vibration (WIV) of a flexibly mounted harbor seal-inspired whisker positioned downstream of a forced-oscillating circular cylinder, simulating the hydrodynamic footprint of a moving object.

The crystallographic B-factor (Bf), also known as the Debye-Waller factor (DWF) or temperature factor, relates to the mean-square displacement of the atoms (X). X may be composed of individual contributions from lattice disorder (LT), static conformational heterogeneity (H) throughout the lattice, rigid body vibration (RB), local conformational vibration (V), and zero-point atomic fluctuation (A). The Bf has been widely employed as a surrogate measure of local protein flexibility, although such relation has not been confirmed.

This study investigated the effects of moderate-intensity aerobic exercise (MIAE) and MIAE combined with isometric resistance exercise on a whole-body vibration (WBV) platform (MIAE+WBV) compared with the effects of no exercise (NEI) on neurocognitive and molecular indices in 71 sedentary, healthy postmenopausal women. Participants were randomly assigned to MIAE (n = 23), MIAE+WBV (n = 23), and NEI (n = 25) groups. Neurocognitive measures, including accuracy rate (AR), reaction time (RT), and electroencephalogram-based event-related potentials (P2, N2, and P3 components) during the Stroop task, in addition to serum levels of insulin-like growth factor 1 (IGF-1), norepinephrine (NE), osteocalcin (OC), carboxylated OC (cOC), and uncarboxylated OC (ucOC), were evaluated before and after the intervention.

To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) among underground coal mine workers, identify the risk factors for WMSDs, and provide a scientific evidence for the prevention and treatment of WMSDs. In March 2024, through cluster sampling, the on-the-job workers who underwent questionnaire surveys and health examinations at a certain coal mine from July to August 2018 were selected as the research subjects. Basic information of employees, ergonomics-related characteristics, and the occurrence status of WMSDs in each part were collected, and multivariate logistic regression was used for analysis.
