| Description | Running economy (energy demand) during long-distance run is important factor for runners. Main indicator of the economy is a oxygen intake. Aim of this work: To find a influence of different run strike (impact of rearefoot and forefoot) on oxygen intake. Methods: 15 men aged 25 years; Run on treadmill with speed 12 km/h (no gradient) of duration 12 min to steady state; less than anaerobic threshold. Results: Minute oxygen intake was by 3,9% higher during forefoot strike (3,21±0,38 l.min-1) than rearfoot strike(3,09±0,36 l.min-1); the difference is a statistical significant, p=0,031. Minute oxygen intake per kilogram was by 3% higher during forefoot strike(44,0±3,6 ml.min-1.kg-1) than rearfoot strike (42,8±4,19 ml.min-1.kg-1), p=0,088. Conclusion: In our group of young runner the running economy was more appreciative during run with rearfoot strike. |
