Supports higher intensity thresholds to exceed lactate threshold in male runners; hypothesis-generating and should not yet change practice.
What percentages of maximal heart rate, heart rate reserve, and VO2max correspond to the lactate threshold and fixed blood lactate concentrations in male runners?
High percentages of maximal heart rate (90%), heart rate reserve (85%), and VO2max (90%) are required to exceed the lactate threshold in male runners.
Weltman et al. (1990) studied this question.
