Abstract: Race walking is the technical and athletic expression of fast walking and it can be considered as a type of endurance performance. The purpose of this study was to examine whether 12 weeks of a specially designed training program results in the further training enhancement of endurance performance and the related physiological parameters in already well-trained race walkers competing at the national and international level. The investigation protocol consisted of determining the maximal oxygen uptake (VO 2peak) and related gas exchange values using an automated cardiopulmonary exercise system and of determining blood lactate variables (aerobic threshold - LTAer and the maximal lactate steady state - MLSS) during walking with proper technique at 8, 10, 12 and 14 km•h -1 for 4 minutes without rest in between. Thereafter, the speed on the treadmill was increased by 0.5 km•h -1 every two minutes until exhaustion to determine VO 2peak. After 12 weeks of a specially designed endurance training, statistically significant increases in VO 2peak (61.8±8.5 mL•kg -1•min -1 pre vs. 66.9±9.5 mL•kg -1•min -1 post training; p<0.05) and blood lactate variables (VO 2-LTAer and VO 2-MLSS; p<0.05) were noted. The obtained results suggest that the applied training program can improve endurance and race performance in previously well trained race walkers. © 2011 Akadémiai Kiadó, Budapest.
