| Description | This study tests if running economy differs on three surfaces (tartan, cinder and asphalt) in long distance runners. 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 VO2 max: 65.9±5 2 ml·min-1·kg-1) by wireless, portable cardiopulmonary stress testing system (Oxycon Mobile). All test subjects were running in the same road racing running shoes. Athletes ran 4 stages lasting 4 minutes at velocities 10, 12, 14 and 16 km·h-1 with a 4-minute break on each surface. ANOVA proved statistical dependence at variable surface (p=0.00) and speed (p=0.00). Interaction isn´t proved (surface x speed, p=0.95). Differences in metabolic-energy running economy indicators were assessed statistically using a Tukey’s HSD test. We found significant differences (p<0.05) between asphalt-cinder and tartan-cinder. 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). The lowest values of oxygen uptake were found out on asphalt surface. The asphalt is probably the most convenient surface according energetic aspect for these specific shoes |
