ABSTRACT This study investigated the effects of WBV in clinical, cardiac, and ambulatory electrocardiographic (Holter) parameters of healthy young and aged male non-athletic dogs. Fourteen dogs were divided into two groups of seven animals: Group I (GI) - young dogs (12.0 and 84.0 months old); Group II (GII) - aged dogs (above 84.0 months old). Dogs were submitted to a single session of WBV (frequencies of 30 and 50 Hz), for 15-min. Variations were identified in the thickness of the interventricular septum and thickness of the left ventricle-free wall values: GI < GII at 5-min before the session. The diameter of the left atrium values showed a difference: GI < GII at 5-min before and 1-min after the session; and a decrease in GII between 5-min before and 1 min after the WBV. Several ambulatory electrocardiography (Holter) parameters demonstrated significant differences between both groups and time-points. A single session of WBV at frequencies of 30 and 50 Hz during 15-min by using a vibrating platform that delivered a vortex wave circulation did not induce significant changes in clinical, cardiac, and ambulatory electrocardiographic (Holter) parameters in healthy young and aged dogs. RESUMO O estudo teve como objetivo avaliar os efeitos agudos da vibração de corpo inteiro (VCI) nos parâmetros clínicos, cardíacos e eletrocardiográficos ambulatoriais (Holter) de cães jovens e adultos hígidos sem raça definida e não atletas. Quatorze cães foram divididos em dois grupos de sete cães, de acordo com a idade: Grupo I (GI) - entre 12,0 e 84,0 meses; Grupo II (GII) - acima de 84,0 meses. Os cães foram submetidos à única sessão de VCI com frequências de 30 e 50 Hz, durante 15 minutos. Foram identificadas variações significativas na espessura do septo interventricular e da espessura da parede do ventrículo esquerdo: GI
