The "TheraPlate" triplanar vibrating platform is an equipment that generates sinusoidal mechanical vibrations that spread throughout the body, increasing regional blood flow and bone mineral density; and neuromuscular stimulation. Since there is no study on the acute affects of this platform on cardiorespiratory parameters in healthy dogs of different age groups, the present study aimed to evaluate the effects of the triplanar vibrating platform "TheraPlate" in the cardiovascular and respiratory parameters. Seven young and seven elderly dogs, of medium size, breed and varied sex, and similar body structure were used. The dogs were submitted to the single session of the TheraPlate triplanar vibrating platform at the frequency of 30 Hz for 5 minutes, followed by increasing the frequency to 50 Hz for 5 minutes and ending at the 30 Hz frequency for 5 minutes without rest. The electrocardiogram was evaluated at different times; Doppler echocardiography; carotid artery doppler; systolic blood pressure; hemogasometry; heart and respiratory rate; rectal body temperature; blood count; biochemistry, cardiac marker, and glycemia were evaluated in diffetent moments. Statistical analyses were performed using the Shapiro-Wilks test, the fit of the mixed model and the Mann-Whitney test. For all analyses, a significant difference was considered when the p-value was less than 0.05. The morphometric data of young and elderly dogs were similar and classified with a body proportion below 1. Parameters which were observed statistically significant differences included: rectal body temperature; interventricular septum thickness in the diastole and the left ventricular wall thickness; left atrium diameter and aortic artery diameter; minimum heart rate; mean heart rate; hemoglobin; alanine aminotransferase; creatinine, calcium, NNmedium, SDNNidx, NN’s, SDNN, SDANN, rMSSD and pNN50 (%), however, the parameters remained within the normal range of the specie. It was concluded that the single session with the triplanar vibrating platform in young and elderly healthy dogs does not induce significant cardiorespiratory alterations.
