In the current study we monitored and directly compared local and global lactate changes in healthy volunteers by means of 1H MEGA-PRESS MRS and blood sampling, respectively, that were induced by exercising the calf muscle. Normalized ratios of lactate to creatine (Lac/Cr) as well as blood lactate concentrations both increased after the exercise indicating high anaerobic exercise conditions. However, different decay time constants of lactate were observed in muscle and blood, which can be ascribed to subsequent processes affecting the blood lactate time courses within the tissue.
