The purpose of this study was to clarify the adverse effects on the rescuer, rescuing with clothes on from drowning. Six rescuers were used as subject to measure their physiological responses such as blood lactate accumulation, heart rate, mental responses such as rating of perceived exertion and to analyze their rescue motion, following by two kinds of carry method, including three types of rescue conditioning in these carry methods. The findings appeared to warrant the following conclutions.
　In the case of the drowned with clothes on, heart rate, blood lactate, and RPE all went up a little and time required was longer by a small percentage, compared to both of rescuer and drowned had swimsuits on. However, in the case of rescuer with clothes on, the value of each measurement all went up and the difference, compared to both of them, was appeared to be significant (p<0.05).
　The VTR showed no significant change in the posture and the position of the drowned between the case of both with swimsuits on and that of the only drowned with clothes on. However, in the case of rescuer with clothes on, the posture and the position of both changed greatly such as their feet sank.
　This study made it clear that how rescue with clothes on deteriorates the condition of rescuing and increases the physical load. It is imperative to inform the danger of rescuing with clothes on thoroughly and in the case of swim in order to rescue inevitably, we should take off as much clothes as possible.
