- Abstract
This study investigated the influence of different passive recoveries on lactate removal and performance in physically active subjects. Eight men (22 ± 3.5 yrs) were randomized with half (n = 4) performing two repeated sprints of 30 sec at Wingate with a passive recovery of 2 min between the maximal efforts, and the other half (n = 4) performing two repeated sprints of 30 sec Wingate with a passive recovery of 6 min between the maximal efforts. During the following week both groups performed 2 repeated sprints inverting the recovery time. Metabolic behavior was followed by removing the kinetics of blood lactate (immediately after, 2, 5, 10, 15, 20, and 30 min) at the end of each session. The findings indicate that both recoveries resulted in a significant decrease (P=0.01) in Poweraverage. However, it was found that the recovery of 2 min showed greater magnitude of decrease (d - 1.88 large effect) in relation to the 6-min recovery (d - 1.08 moderate effect). Metabolic behavior showed no significant differences in lactate removal among different periods of passive recovery (P=0.05). The results suggest that the two models of passive recovery were not sufficient to maintain the performance, and no significant differences were found in the removal and total lactate concentrations.
