Aim of the present study is to clarify energy expenditure of gymnastic exercise during water immersion. Method : 13 males participated to the test. Oxygen consumption (V^^.O_2) and ventilation were continuously measured by open circuit. Heart rate (HR) was automatically obtained by telemetoring. Six kinds of repeating movement of extremities were performed on land and in water in the same manner. Immersing depth was to the xyphoid level. Rhythms of the movement were adjusted so as to continue for several minutes. Result : Their OPW were 14∿20ml/kg/min, MV were 38∿53l/min. OPW increased remarkably by swings of both arms crossing in front of chest or alternant back-and-forth, and swings of a hemi-leg in water, compared to that on land. OPW was as half as on land by jump in situ, and equivalent by steps like marching. Notably, oxygen pulse increased by arm and leg exercise more than that on land, accompanied by increase of ventilation. Gymnastic exercise in water showed different effect on oxygen consumption and cardiac response from that on land. Manner of the movements in water also affect the difference. Those kinds of exercise in water can be utilized clinically for training and promotion of fitness.
