The aim of this study was to characterize the physiological and metabolic demands of a rescue simulation and identified the determinants. Eight male beach lifeguards performed in different days: (a) an incremental test on a treadmill determine maximal heart rate (HR max), maximal oxygen uptake (VO2 max), and blood lactate concentration ([La]) profile; (b) a 300-m maximal specific swimming test in the pool; and (c) two rescue simulation performances in a surf beach without (RS1) and with a rescue tube (RS2). The performance time and [La]PEAK for pool testing (386 ± 54 sec and 13.5 mMol·L-1 ), RS1 (351 ± 70 sec and 14.1 mMol·L-1 ), and RS2 (360 ± 47 sec 13.5 mMol·L-1 ) were not significantly different. No significant correlations were found between the laboratory-based measures and pool performance testing with both rescue performances. Significant correlation was found between R1 and R2 (r = .83). It is concluded that the simulated rescue on the surf beach showed a high physiological and metabolic demand and seems to be strongly independent of environment conditions, thus requiring a different set of swimming skills compared to those acquired only with pool-swimming training.
