Aim.:The aim of this paper was to evaluate the blood lactate ([La-]b) recovery kinetics and determinate the associations between the [La-]b recovery kinetics and physical capacity on physically active men.
Methods: Seventeen healthy and physically active men took part in three recovery protocols (passive, cycling and walking), subsequent to a Wingate Anaerobic Test. The [La-]b was measured by a potentiometer-enzymatic analysis, the maximum O2 consumption (VO2max) using a metabolic cart, the heart rate by a heart rate monitor and the body mass from anthropometry.
Results: Active recovery (walking and cycling recovery) had smaller peak [La-]b concentration time, [La-]b smaller area under the curve ([La-]b auc), and higher [La-]b removal (γ2) than passive recovery. Moreover, the walking recovery had the smallest [La-]b accumulation final, the smallest [La-]b auc, and the highest [La-]b recovery index (p<0.05). The [La-]b recovery kinetics was depend on physical capacity of the subjects: during passive recovery >79% of the variance were explained by workload auc, muscle mass and lactate threshold (LT); during active recovery >73% of the variance were explained by age, muscle mass, VO2max and LT.
Conclusion: The variations on [La-]b recovery kinetics depended principally by the subject’s physical capacity. The [La-]b recovery kinetics were more efficient during active than during passive recovery (walking >cycling >passive recovery).
