Description The aim of this paper was to compare running economy on different surfaces (tartan, cinder and asphalt) between long distance runners (n = 10). We used Oxycon Mobile, Tanita BC-543 a Polar S610i. All test subjects were running at the same road racing running shoes. Subjects ran 2 stages for 4 minutes on velocities 10 and 12 km/h with 4 minute break on each surface. The monitored parameters were average oxygen uptake (VO2; ml/min) resp. relative oxygen uptake per kilogram of runner’s body mass (VO2/BM; ml/min.kg) on different velocities. Differences metabolic-energy running economy indicators were assessed statistically using a post-hoc Fisher's LSD test. We did not found significant differences (p <0,05) between surfaces, lowest values (VO2 and VO2/BM) were on asphalt. Differences of average values of VO2 on tartan (2574 resp. 2936 ml/min), cinder (2509 resp. 2986 ml/min) and asphalt (2469 resp. 2810 ml/min) were on the edge of device error (50 ml/min), so the only conclusion is the asphalt is the most convenient surface according energetic aspect for this specific shoes.
