Does a short intervention with vibration foam roller recover lifeguards better after a water rescue? A pilot study

The aim of this study was to analyze the effects a recovery program based on foam roller with and without vibration blood lactate clearance perceived fatigue after water rescue. A quasi-experimental crossover design carried out compare passive (PR) short protocol (FR) (VFR) 100 m rescue in 7 volunteer lifeguards. Blood exertion were measured before rescue, also 5-min intervention. levels decrease significantly ( p = 0.013; effect size 0.97) < 0.001; 1.62). Passive did not show significant differences clearing lactate. Fatigue all methods, but has higher global VFR legs. FR clear more than PR, subsequently increase physical conditioning perform another effort.
