For designing the training plan and determining the pace of individual workouts, I think it doesn't matter...
Maximum heart rate is the maximum number of beats per unit of time that the heart can reach during physical activity (at the point of exhaustion).
Anaerobic threshold is the intensity of exercise, and therefore the point in heart rate and running pace, at which the production of lactic acid occurs at a greater rate than its removal, and from there on the lactic acid concentration begins to increase significantly (the concentration of lactic acid in the blood). for the majority is about 4mmol/L).
Aerobic threshold is the intensity of exercise and thus the point in heart rate and running pace, at which there is a balance between lactic acid production and its removal (the concentration of lactic acid in the blood for the majority is approximately 1.5 – 2mmol/L). After that point, lactic acid removal occurs at a lower rate than its production.
