Abstract：
:A paucity of empirical research exists into surf lifesaving competition from which coaches and athletes may formulate training and recovery strategies. Seventeen (male=9; female=8) high-performance surf lifesavers (21.2+/-3.9 years) contested multiple rounds of team and individual events at a 2-day surf lifesaving competition. Individual events consisted of the multi-discipline ironman (IRON), paddle board (BOARD) and surf swim (SWIM). Blood lactate (BLa), rating of perceived exertion (RPE) and heart rate (HR) were determined following heats, semi-finals and final. IRON HR and RPE following semi-finals (153.0+/-21.6beatsmin(-1) and 14.4+/-1.5) and final (171.0+/-9.1beatsmin(-1) and 19.1+/-0.2) were greater than heats (141.8+/-17.2beatsmin(-1) and 12.0+/-1.9; p<0.05) and final BLa (10.5+/-2.8mmolL(-1)) was greater than heats (5.8+/-3.6mmolL(-1); p<0.05). BOARD BLa and HR were greater after the final (9.0+/-2.8mmolL(-1) and 159.0+/-19.9beatsmin(-1)) compared to heats (4.7+/-2.4mmolL(-1) and 133.0+/-17.1beatsmin(-1); p<0.05). No significant differences were identified for SWIM. RPE-HR relationships were identified for pooled IRON and BOARD results following semi-finals (0.668; p<0.05) and finals (r=0.741; p<0.05). In conclusion, high-performance surf lifesavers employ race strategies with all-out maximal exercise limited to semi-finals and finals.
