Resumo

Os ambientes costeiros apresentam desafios dinâmicos que necessitam de respostas rápidas e eficientes durante emergências aquáticas. Os salva-vidas, como elos centrais da cadeia de intervenção, contam com diversas ferramentas, sendo o tempo de resgate primordial. A escolha das nadadeiras, especificamente as longas e as curtas, desempenha um papel crítico na otimização do desempenho do salva-vidas durante os resgates. Este estudo cruzado randomizado explora o impacto do tamanho das nadadeiras nos resgates oceânicos, empregando uma amostra de 14 salva-vidas. Nadadeiras longas (LFs) e nadadeiras curtas (SFs) foram comparadas em termos de tempo de resgate (TR) e carga fisiológica (PL). Os testes incluíram resgates oceânicos sem nadadeiras (R), com LF (R-LF) e com SF (R-SF). As variáveis ​​​​registradas abrangeram o tempo de nado para aproximação, o tempo de reboque, o tempo geral de resgate, as taxas de esforço percebido (RPEs) e a concentração de lactato pós-resgate. Nadadeiras longas demonstraram desempenho superior para o nado de abordagem e nos tempos de reboque em comparação com nadadeiras curtas e sem nadadeiras (p < 0,001). O tempo geral de resgate foi favorecido significativamente pelas nadadeiras longas (p <0,001), indicando sua eficiência em cenários práticos de resgate oceânico. Fisiologicamente, nadadeiras longas induziram menor esforço percebido nos braços (p = 0,033) em comparação com nadadeiras curtas. As concentrações de lactato pós-resgate não revelaram diferenças significativas (p > 0,05). Este estudo demonstra que nadadeiras longas melhoram significativamente o desempenho do salva-vidas durante resgates no oceano, reduzindo o tempo de resgate e aliviando a fadiga dos braços.
