Abstract: The main objective of this study was to analyse the relationship between the performance in a maximum incremental test for lifeguards, the IPTL, and the effectiveness of a 200 m water rescue on the beach. Initially, 20 professional lifeguards carried out the IPTL in the pool and then they performed a 200 m water rescue on the beach. The maximum oxygen uptake (VO 2max ) in the IPTL was estimated. In both tests, heart rate (HR), blood lactate (La) and time achieved were measured. The VO 2max estimated in the IPTL (VO 2IPTL ) was 44.2 ± 4.7 mL·kg·min ?1 , the time reached in the IPTL (Time IPTL ) was 726 ± 72 s and the time spent in the rescue (Time Rescue ) was 222 ± 14 s. The results showed that the time reached in the pool (Time IPTL ) was the best predictor variable of the performance in water rescue (Time Rescue ) (R 2 = 0.59; p < 0.01). A significant correlation was also observed between the estimated maximum oxygen uptake and the beach rescue performance (R 2 = 0.37; p = 0.05). These results reveal that the IPTL, a maximum incremental test specific to lifeguards, allows the estimation of the effectiveness of a 200 m rescue on the beach.
