“…In the current study the results of VO2Max obtained during the laboratory test confirmed a high level of physical condition in the sample studied. The mean values recorded were higher than the recommended minimum for the aptitude of professional lifeguards (Prieto, Nistal, Méndez, Abelairas-Gomez, & Barcala-Furelos, 2015). The results were similar to those found in previous studies of other rescue workers (Prieto et al, 2010, Salvador et al, 2014 and higher than those achieved by other rescue groups such as firefighters or first responder groups (Prieto, González, Del Valle, & Nistal, 2013).…”

This study was designed to validate an incremental test predicting maximum oxygen uptake for lifeguards. A maximum incremental test was performed in the laboratory (i.e., treadmill run) and in the pool (i.e., swim) by 10 certified lifeguards. The values of maximum oxygen uptake (VO2Max), maximum heart rate (HRMax), and lactate (LaMax) achieved during both tests were analyzed. The VO2Max (0.87, p =.001), HRmax (0.85, p = .002) and LaMax (0.67, p <.05) values showed significant correlations between the laboratory tests and the pool tests. These results showed that the Incremental Pool Test for Lifeguards (IPTL) was valid (i.e., concurrent validity) for obtaining the maximum oxygen uptake of a rescuer. Using this swim test, lifeguards and their supervisors will be able to individualize their training in order to improve their performance in a water rescue and perhaps reduce the numbers of fatal drownings.

“…One of the most important factors to take into consideration when performing a water rescue is the physical condition of lifeguards, determined by the physiological demands of the rescue. In this sense, it has been shown that the values of heart rate [6,7], blood lactate [8,9] and oxygen uptake [10] increase until they approach maximum values during a rescue, which means that aerobic capacity and power are fundamental to the lifeguard's performance during the rescue [7,11].…”

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 (VO2max) in the IPTL was estimated. In both tests, heart rate (HR), blood lactate (La) and time achieved were measured. The VO2max estimated in the IPTL (VO2IPTL) was 44.2 ± 4.7 mL·kg·min−1, the time reached in the IPTL (TimeIPTL) was 726 ± 72 s and the time spent in the rescue (TimeRescue) was 222 ± 14 s. The results showed that the time reached in the pool (TimeIPTL) was the best predictor variable of the performance in water rescue (TimeRescue) (R2 = 0.59; p < 0.01). A significant correlation was also observed between the estimated maximum oxygen uptake and the beach rescue performance (R2 = 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.

“…Lifeguards require a high level of physical conditioning to respond to the physiological demands of a water rescue [1]. Drowning is a global health problem, which in 2017 caused 295,210 drowning deaths [2], a number that would be much higher without lifeguard prevention and rescues.…”

This study aimed to evaluate the degree to which transcutaneous electrical stimulation (ES) enhanced recovery following a simulated water rescue. Twenty-six lifeguards participated in this study. The rescue consisted of swimming 100 m with fins and rescue-tube: 50 m swim approach and 50 m tow-in a simulated victim. Blood lactate clearance, rated perceived effort (RPE), and muscle contractile properties were evaluated at baseline, after the water rescue, and after ES or passive-recovery control condition (PR) protocol. Tensiomiography, RPE, and blood lactate basal levels indicated equivalence between both groups. There was no change in tensiomiography from pre to post-recovery and no difference between recovery protocols. Overall-RPE, legs-RPE and arms-RPE after ES (mean ± SD; 2.7 ± 1.53, 2.65 ± 1.66, and 2.30 ± 1.84, respectively) were moderately lower than after PR (3.57 ± 2.4, 3.71 ± 2.43, and 3.29 ± 1.79, respectively) (p = 0.016, p = 0.010, p = 0.028, respectively). There was a significantly lower blood lactate level after recovery in ES than in PR (mean ± SD; 4.77 ± 1.86 mmol·L−1 vs. 6.27 ± 3.69 mmol·L−1; p = 0.045). Low-frequency ES immediately after a water rescue is an effective recovery strategy to clear out blood lactate concentration.
