Título: | Is Low-Frequency Electrical Stimulation a Tool for Recovery after a Water Rescue? A Cross-Over Study with Lifeguards | Autor: | Barcala-Furelos, Roberto González-Represas, Alicia Rey, Ezequiel Martínez-Rodríguez, Alicia Kalén, Anton Marques, Olga Rama, Luís |
Palavras-chave: | transcutaneous electric nerve stimulation; task performance and analysis; tensiomyography; lactate; lifesaving | Data: | 12-Ago-2020 | Editora: | MDPI | Título da revista, periódico, livro ou evento: | International Journal of Environmental Research and Public Health | Volume: | 17 | Número: | 16 | Resumo: | 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. | URI: | https://hdl.handle.net/10316/106177 | ISSN: | 1660-4601 | DOI: | 10.3390/ijerph17165854 | Direitos: | openAccess |
