Abstract
This study evaluated the serum cortisol response to a single session of whole-body vibration (WBV) in healthy adult dogs. Ten healthy adult medium dogs, females and males, aged between 24 and 48 months and with body weight between 10.1 and 17.9 kg were used. A single WBV session at a frequency of 30 Hz for 5 min (3.10 mm peak displacement, 11.16 m/s2 peak acceleration, and 0.29 m/s velocity), then 50 Hz for 5 min (3.98 mm peak displacement, 39.75 m/s2 peak acceleration, and 0.62 m/s velocity), and finishing with 30 Hz for 5 min (3.10 mm peak displacement, 11.16 m/s2 peak acceleration, and 0.29 m/s velocity) was performed. Serum cortisol, heart and respiratory rate, and systolic blood pressure were evaluated at different time points: 1 min before WBV (1PRE) and 1 min (1POST), 60 min (60POST), and 360 min (360POST) after the WBV session. An increase (P = 0.0417) of the serum cortisol values was observed between 1PRE and 1POST and a decrease (P = 0.0417) between 1POST and 60POST and between 60POST and 360POST. However, the values remained within the reference range. The heart and respiratory rate and the systolic blood pressure remained unchanged. Our findings suggest that a single bout of WBV (5 min of 30 and 50 Hz) using a vibrating platform that delivered a vortex wave circulation does not modify the serum cortisol levels and clinical parameters of healthy adult dogs.
Highlights
Whole-body vibration (WBV) is a mechanical vibration stimulus that propagates throughout the body by using vibrating platforms [1, 2]
The dogs did not require training standing on the vibrating platform, and they presented good acceptance of the WBV session at a frequency of 30 Hz, they tried to sit when the frequency increased from 30 to 50 Hz
There were no changes in food and water intake and presence of diarrhea or vomiting 24 h after the WBV session
Summary
Whole-body vibration (WBV) is a mechanical vibration stimulus that propagates throughout the body by using vibrating platforms [1, 2]. The vibrating platform technology produces movements along the x, y, and z planes, and vortex wave circulation [3] and has been used to treat injuries and other debilitating conditions in human patients to strengthen and increase muscle mass and to improve cardiovascular functions [1, 5, 6]. Whole-Body Vibration in Dogs obtained by using WBV as a rehabilitation modality in animals. These positive outcomes, such as increased muscle mass, can improve the stability of joints affected by a degenerative disease (elbow and hip dysplasia) since these conditions can induce muscle atrophy [8]
