Increased resting lactate levels and reduced carbohydrate intake cause νLa.max underestimation by reducing net lactate accumulation-A pilot study in young adults.

Modulation of testing conditions such as resting lactate (La) levels or carbohydrate intake may affect the calculation of the maximal glycolytic rate (νLa.max). To evaluate the impact of elevated La as well as reduced and increased carbohydrate availability on νLa.

A modified formula using energy system contributions to calculate pure maximal rate of lactate accumulation during a maximal sprint cycling test.

This study aimed at comparing previous calculating formulas of maximal lactate accumulation rate ( ) and a modified formula of pure (P ) during a 15-s all-out sprint cycling test (ASCT) to analyze their relationships. Thirty male national-level track cyclists participated in this study ( = 30) and performed a 15-s ASCT. The anaerobic power output (W and W), oxygen uptake, and blood lactate concentrations (La) were measured.

Lactate Thresholds and the Simulation of Human Energy Metabolism: Contributions by the Cologne Sports Medicine Group in the 1970s and 1980s.

Today, researchers, practitioners, and physicians measure the concentration of lactate during a graded exercise test to determine thresholds related to the maximal lactate steady state (maxLass) as a sensitive measure of endurance capacity. In the 1970s and 1980s, a group of Cologne-based researchers around Wildor Hollmann, Alois Mader, and Hermann Heck developed the methodology for systematic lactate testing and introduced a 4 mmolL lactate threshold. Later, they also developed the concept of the maxLass, and Mader designed a sophisticated mathematical model of human energy metabolism during exercise.

The ability of energy recovery in professional soccer players is increased by individualized low-intensity exercise.

The aim of this study was to investigate whether individualized low-intensity exercise (ILIE) within the recovery domain before lactate threshold 1 (LT 1) improves energetic recovery and general endurance capacity in professional soccer players. Twenty-four professional soccer players (age: 24.53 ± 4.
