摘要

The purpose of this study was to make clear the effects of water temperature during foot immersion (foot bath) on heart rate, blood pressure, rectal temperature and autonomic nervous system modulation. The subjects performed foot immersion at 25, 35, 41 and 45 degrees Celsius at random, during different days, but always at the same time. Cardiac autonomic nervous system modulation was estimated with the power spectrum analysis of heart rate variability by using the Fast Fourier Transformation. The two frequency components of HRV was measured by integrate low frequency (LF; 0.04-0.15 Hz) and high frequency (HF; 0.15-0.40 Hz). HF was used as an indicator of cardiac vagal modulation and was showed logarithmically (LogHF). LogHF during foot immersion at 35 and 41 degrees Celsius was significantly increased. These data indicate that cardiac vagal activity was affected by water temperature during foot immersion (foot bath).
