The purpose of this study was to investigate the physical characteristics and aquatic skills and physical workout loading for surf rescue of lifesaving. Twenty eight lifesavers participated in this study. Nine subjects were experts aged 23±1.1 (top level group : TG), eleven were experienced persons aged 20.1±0.4 (experienced group : EG) and eight beginners aged 19.1±0.5 (beginner group : BG). The physical characteristics were determined by measuring body composition, aerobic and anaerobic capacities. The aquatic skills were determined by measuring the times of 200m board slalom course, 25m porpoise & 25m swim, 50m swim, 25m swim & 25m swim with a manikin. To determine physical workout loading for surf rescue in lifesaving, heart rate, rating of perceived exertion, oxygen intake and blood lactate concentration were measured. The aerobic and anaerobic workout capacities in TG and EG were superior to those in BG. Times of 25m swim and 25m swim with a manikin, tube rescue and board rescue simulation in TG and EG were shorter than the those in BG. Time of board rescue in TG was significantly shorter than those in EG. Blood lactate concentration after surf rescue of lifesaving in TG was lower than those in EG and BG. These results indicate that in order to conduct lifesaving safely and quick it is essential in improving aerobic and anaerobic powers and aquatic skills for surf rescue using rescue board and tube.
