Objective: High-intensity aerobic training improves the physical fitness of lifeguards, but it may induce fatigue when performed prior to an aquatic rescue. This study examines the effect of an aerobic training session on performance during a simulated rescue.
Methods: Twenty professional lifeguards performed two 200-meter aquatic rescues, separated by 72 hours. Before the second rescue, half of the participants completed a high-intensity aerobic training session (Experimental Group, EG), while the other half rested (Control Group, CG). Time variables, heart rate, blood lactate concentration, and perceived exertion were measured.
Results: No differences were observed between groups in the first rescue, except for extraction time and total time, where EG was faster (p<0.01). In the second rescue, after the training session, EG showed poorer performance in some phases of the rescue. The training session maintained an intensity of 80–95% of maximum heart rate, confirming its high physical demand.
Conclusion: A prior aerobic training session can increase fatigue and negatively impact performance in a subsequent aquatic rescue. It is recommended that workload be carefully planned on lifeguards' workdays to avoid potential operational risks.
