Abstract
The aim of this study was to evaluate the effects of a single-session of whole-body vibration (WBV) exercise on haematological and serum biochemical parameters and serum cortisol levels in healthy adult cats. Ten healthy neutered crossbred cats, five males and five females, aged 2 to 4 years and weighing 3.25-5.15 kg, were enrolled. All cats were tested in the same period starting at 12:00 a.m. and under same environmental conditions. A 1 h period of acclimatisation and rest was completed prior to the WBV session. During the WBV session, the cat was placed in a standing position on the centre of the vibrating platform. Each cat was exposed to a single WBV session. The protocol was 30 Hz for 5 min, followed by 50 Hz for 5 min and finishing with 30 Hz for 5 min. The peak displacements were 3.10 mm and 3.98 mm and the peak accelerations 55.0 m/s and 195.96 m/s. Complete blood cell count, serum biochemistry (alanine aminotransferase, creatinine, creatine phosphokinase) and serum cortisol were determined at three time-points: before (T0), immediately after (T1), and at 4 h after the end of the WBV session (T2). Immediately after increasing the frequency from 30 to 50 Hz, two cats (20%) tried to sit and showed signs of agitation that ceased after 15 s. No cat tried to jump out. The variables presented no statistically significant differences among the time-points. In conclusion, a 15 min session of WBV exercise at frequencies of 30, 50 and 30 Hz does not cause significant changes in haematological or serum biochemical parameters, nor in serum cortisol levels in healthy adult cats.

Whole Body Vibration Retards Progression of Atherosclerosis via Insulin-Like Growth Factor 1 in Apolipoprotein E-Deficient Mice. BIOMED RESEARCH INTERNATIONAL 2018; 2018:4934861. [PMID: 29707570 PMCID: PMC5863334 DOI: 10.1155/2018/4934861] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/05/2017] [Revised: 12/06/2017] [Accepted: 02/04/2018] [Indexed: 11/17/2022]
Abstract
Whole body vibration (WBV) has a marked impact on lipid metabolism and the endocrine system, which is related to the progression of atherosclerosis (AS). To investigate the effects of WBV, we measured the atherosclerotic plaque area of apolipoprotein E-knockout (ApoE−/−) AS mice, which were trained by WBV (15 Hz, 30 min) for 12 weeks. Simultaneously, serum levels of lipids, insulin-like growth factor 1 (IGF-1), insulin-like growth factor 1 receptor (IGF-1R), interleukin 6 (IL-6), and the mRNA and protein levels of the same in the aorta were compared between the control and WBV groups. The results indicated that WBV significantly reduced the atherosclerotic plaque area with lower very low-density lipoprotein (VLDL) and oxidized low-density lipoprotein (ox-LDL) in the blood. Moreover, the levels of IGF-1 in serum and expression of IL-6, IGF-1R, and p-IGF-1R protein in the mice aorta decreased significantly in the WBV group. In addition, we found that serum IGF-1 in mice increased to the highest concentration in 30 min after WBV for 10, 30, 60, and 120 minutes. These results suggested that appropriate WBV may delay the progression of AS, which was associated with acutely elevated serum IGF-1 and lower levels of IGF-1 and IL-6 in the aorta for long-term treatment.

Abstract
Sound pressure waves surround individuals in everyday life and are perceived by animals and humans primarily through sound or vibration. When sound pressure waves traverse through a solid medium, vibration will result. Vibration has long been considered an unwanted variable in animal research and may confound scientific endeavors using animals. Understanding the characteristics of vibration is required to determine whether effects in animals are likely to be therapeutic or result in adverse biological effects. The eighth edition of the "Guide for the Care and Use of Laboratory Animals" highlights the importance of considering vibration and its effects on animals in the research setting, but knowledge of the level of vibration for eliciting these effects was unknown. The literature provides information regarding therapeutic use of vibration in humans, but the range of conditions to be of therapeutic benefit is varied and without clarity. Understanding the characteristics of vibration (eg, frequency and magnitude) necessary to cause various effects will ultimately assist in the evaluation of this environmental factor and its role on a number of potential therapeutic regimens for use in humans. This paper will review the principles of vibration, sources within a research setting, comparative physiological effects in various species, and the relative potential use of vibration in the mouse as a translational research model.
