| Popis | This study compared 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 4 stages for 4 minutes on velocities 10, 12, 14 and 16 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/BM (for 10, 12, 14, resp. 16 km/h) on tartan (35.76, 40.83, 47.25 and 54.51 ml/min/kg), cinder (34.91, 41.60, 47.48 and 54.28 ml/min/kg) and asphalt (34.42, 39.20, 44.44 and 52.34 ml/min/kg) 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. |
