    Speed up recovery is fundamental in sport disciplines in which competitors must perform repeated trials within the same competition. The main objective of this study was to determine the effect of high-frequency whole body vibration (WBV) on blood [Lac] removal and heart rate (HR) after an all-out test. The participants performed a 4 x 100 m all-out test every 48 h in a random cross-over fashion, and a blood [Lac] removal protocol was applied after each test: a) 20 min seated (REST); b) squatting on a vibrating platform (S+V); and c) squatting on a non-vibrating platform (S-V). Blood [Lac] and HR were measured at rest, immediately after the 4 x 100 m all-out test (min 0), and at 10 and 20 min during the removal protocols. The results showed that the 3 protocols displayed significantly decreased blood [Lac] after 20 min (REST, S+V, and S-V removed Δ 6.6; Δ 10.5; and Δ 11.1 mmol•L-1, respectively). However, there were no significant differences in the blood [Lac] removal level between the S+V and S-V conditions. Interestingly, the S-V participants showed increased HR levels during the active recovery compared with the REST and S+V conditions. The effect of high-frequency WBV is not an additional stimulus to increase the blood [Lac] removal capacity in active young men, although WBV appeared to elicit less cardiovascular stress during recovery. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF)
