| Description | Purpose: This study tests if running economy differs on three surfaces (tartan, cinder and asphalt) in long distance runners. Methods: We measured oxygen uptake (parameter of running economy) breath-by -breath in 30 long distance runners (age: 25+-4 years, height: 183+-7 cm and body mass: 72+-6 kg and VO2max: 65,9+-5 2 ml.min-1.kg-1) by wireless, portable cardiopulmonary stress testing system (Oxycon Mobile). All test subjects were running at the same road racing running shoes. Athletes ran 4 stages for 4 minutes on velocities 10, 12, 14 and 16 km.h-1 with 4 minute break on each surface. Differences metabolic-energy running economy indicators were assessed statistically using a post-hoc Fisher's LSD test. Results: We found significant differences (p < 0,05) between asphalt and cinder for 12, 14 and 16 km.h-1. The lowest values were measured on asphalt surface. Differences of average values of oxygen uptake (for 10, 12, 14, resp. 16 km.h-1 ) on tartan (35.3, 41.1, 47.7 and 54.5 ml.min-1.kg- 1), cinder (36.1, 42.6, 49.3 and 56.2 ml.min-1.kg-1) and asphalt (35.1, 39.9, 46.7 and 53.5 ml.min- 1.kg-1) were on the edge of device error (50 ml.min-1). Conclusions: We found out the lowest values of oxygen uptake on asphalt surface. The asphalt is probably the most convenient surface according energetic aspect for these specific shoes. |
