Abstract: This study aimed to analyse the validity of glucose minimum speed (GMS) for lactate minimum speed (LMS) assessment during running and their relationship to, endurance performance. Eight male trained runners (28.7+/-9.0 years) volunteered to take part in this study and underwent an official 10-km road race and a track lactate minimum test (LMT) (0.5-km sprint plus 6 x 800 m from 87 to 98% of maximal 3-km speed). Lactate and glucose minimum speeds were considered those related to the minimum blood lactate and glucose concentrations respectively attained during the graded phase of LMT. Significant correlations (p<0.05) were found between LMS and GMS (r=0.72) and LMS and 10-km performance (r=0.83), but not between GMS and 10-km performance (r=0.49). No significant differences (p>0.05) were found between LMS (4.75+/-0.08 m/s), GMS (4.73+/-0.07 m/s) and 10-km mean speed (4.79+/-0.17 m/s). In conclusion, we found GMS to be a good predictor of LMS during track LMT, LMS being well related to endurance running performance.
