Two males and four females served as subjects (n=6, mean age: 25.3yrs). Water temperature was 31. Heart rate, blood pressure and oxygen uptake were measured during relaxation for each condition. Cardiac autonomic nervous system activity was estimated with power spectrum analysis of heart rate variability. High frequency (HF; 0.15 0.40 Hz) and areas and the ratio of low frequency (LF; 0.04 0.15 Hz) to HF (LF/HF) were used as an indicator of cardiac vagalactivity and sympathetic nervous activity, respectively. There were no significant differences found in blood pressure and oxygen uptake forany of the conditions. Nu (normalized unit; %) of HF during SW and W were significantly higher than C. Heart rate and LF/HF during SW and W were significantly lower than C. These data suggested that cardiac vagalactivity and sympathetic nervous activity during relaxation were affected by immersion.
