Aim. The objective of this study was to determine the effect of active (AR), passive (PR) and stretching (SR) recovery on lactate’s parameters after supramaximal exercise.
Methods. Thirty male volunteers participated in the study. Twelve subjects realised AR, 12 SR and the remaining 6 subjects were assigned as control group performed PR. All participants completed a 30-second supra-maximal exercise at 140% of maximal aerobic speed followed by 30-min of AR, PR or SR period. Blood lactate recovery curves from the supramaximal exercise were fitted to a biexponential time function.
Results. The parameters of lactate exchange (γ1) and removal (γ2) abilities were found to be higher for AR than either SR or PR. During SR the subjects displayed significantly higher γ2 values than during PR (P<0.05), but γ1 was not significantly different between the two modes of recovery. During AR there were a significant shortening in t-[La]peak (P<0.001 for all comparisons) and a significant lowering in peak blood lactate concentration ([La]peak) (P<0.001) than both SR and PR, whereas, no significant differences were observed in the time to lactate-peak (t-[La]peak) and [La]peak between SR and PR. Additionally, SR showed a significantly shorter lactate half time (t-1/2[La]) than PR (P<0.001). But AR showed the shortest t-1/2[La] than SR and PR.
Conclusion. The present study shows that active recovery is more effective than PR or SR. SR type used in this study could also be of interest compared to PR.
