Cross-sectional study approved by local ethics committee (Certificado de Apresentação para Apreciação Ética - CAAE - 19826413.8.0000.5259) and Trial registration (Registro Brasileiro de Ensaios Clínicos – REBEC - RBR-738wng). Using Infrared thermography (IRT), Tsk and thermal symmetry of the posterior lower extremities (thigh, knee, calf and heel) were examined in 19 healthy participants. IRT was assessed during 60-second WBVE exposures of 0, 30 and 50 Hz. From the adjusted linear mixed effects model, vibration frequency, time and regions of the lower extremity were significant (p<0.001). However, the variable laterality was not significant (p=0.067) and was excluded from the adjusted statistical model. The adjusted model was significant (p<0.01) and all variables in the model were significant (p<0.01) indicating that Tsk decreases with time, independently of the vibration frequency. The value of the Pseudo-R-Squared for the model was 0.8376. The presented mathematical model of the current study may be useful to justify the patterns observed for all vibration frequencies between and 0 and 50 Hz.
