The purpose of this study was to examine the influence of water immersion on heart rate (HR) during arm cranking exercise. Six men performed the exercises with (WI-condition) or without water immersion (C-condition) to the xiphoid process on incremental loads. Constant rate exercises for 10 min were performed in both WI- and C-conditions at each work load corresponding to 10, 30 and 50% of the maximal work rate (Wmax). Compared with C-condition, no difference was observed in Wmax and the parameters of respiratory functions under WI-conditions, while water immersion-induced bradycardia (WIB) was observed at rest, 10, 30, 50, and 100% Wmax, by -10.4±1.9, -12.3±4.0, -9.5±3.7, -13.2±4.8, and -7.7±3.4 bpm, respectively. These results suggested that the WIB was similar (average -8〜-13 bpm) at rest and at any level of exercise intensities in water immersion.
