“…The quality of chest compression worsens after a water rescue action by 26-28%, so it has been emphasized that the use of additional equipment (fins and rescue tubes) provides benefit in emergency situations [19]. Some publications suggest that lifesavers clear out blood lactate more efficiently when performing an active recovery protocol [20]. The quality of cardiopulmonary resuscitation performed by lifeguards using a CPRmeter monitor improved significantly in the feedback group, compared with the non-feedback group [2].…”

Background: The ability to perform high-quality cardiopulmonary resuscitation is one of the basic skills for lifeguards. The aim of the study was to assess the influence of chest compression frequency on the quality of the parameters of chest compressions performed by lifeguards. Methods: This prospective observational, randomized, crossover simulation study was performed with 40 lifeguards working in Warsaw, Wroclaw, and Poznan, Poland. The subjects then participated in a target study, in which they were asked to perform 2-min cycles of metronome-guided chest compres

“…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. Drowning is triggered, within seconds or minutes [3], so the intensity of lifeguards' water rescues is very high, with lactate production of over 10 millimoles [4,5] and great physiological and muscular fatigue [6]. Considering a lifeguard can have more than one rescue per day [7], the physiological and metabolic disturbances induced by a water rescue can have detrimental effects on the performance of subsequent 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.

“…Researchers have also found that RM may reduce post exercise decrements in muscle performance (Macdonald et al, 2014), increase posttreatment pressure pain thresholds (PPT) (Aboodarda et al, 2015;, and reduce the Journal of Human Kinetics -volume 71/2020 http://www.johk.pl effects of delayed onset muscle soreness in healthy individuals (Macdonald et al, 2014). Several recent studies have also documented positive post-exercise effects of RM for different sports (Rey et al, 2017), occupations (Kalen et al, 2017), and fibromyalgia (Ceca et al, 2017). For rehabilitation, RM may have some benefits due to possible neurophysiological effects that occur to the target and surrounding tissues after treatment (Aboodarda et al, 2015;Monteiro et al, 2017).…”

The aims of this study were to (1) compare the immediate post-treatment effects of an instructional video versus a self-preferred program on the hip range of motion and a pressure pain threshold using two different density roller balls, and (2) compare the effects of the two roller balls on those variables. Forty adults were randomly allocated into four groups: (1) MB1-video, (2) MB1-self-preferred, (3) MBX-video, and (4) MBX-self-preferred. Participants followed a video or a self-preferred program using either a moderate (MB1) or a hard (MBX) density ball. Main outcomes were passive hip internal rotation, external rotation, and a pressure pain threshold. For MB1, the video produced greater outcomes than the self-program for external rotation (10◦ versus 2◦), internal rotation (7◦ versus 2◦), and the pain threshold (210 kPa versus 44 kPa). For MBX, the video produced greater outcomes than the self-program for external rotation (8◦ versus 1◦), internal rotation (5◦ versus 1◦), and the pain threshold (184 kPa versus 30 kPa). When comparing roller balls, the MB1 produced greater outcomes than the MBX for external rotation (10◦ versus 8◦), internal rotation (7◦ versus 5◦), and the pain threshold (210 kPa versus 184 kPa) with the video. For the self-preferred program, the MB1 produced greater outcomes for external rotation (2◦ versus 1◦), internal rotation (2◦ versus 1◦), and the pain threshold (44 kPa versus 30 kPa). The instructional video and a moderate density ball produced greater immediate post-treatment outcomes than the self-program and a hard density ball. Professionals should consider using the video to teach technique and match clients to a specific density-type roller ball.
