| Description | The research project focuses on the problem of the optimum cross step in long distance run. Step should be energetically most favourable – economics. We want to answer the question whether and under what conditions it is energetically preferable to endurance runner‘s pace with the impact on the forefoot or rearfoot. Testing subjects were 15 athletes. Athletes held running pace 12 km.h-1 . When we evaluated results, we focused on indicators running economy – minute oxygen uptake, minute oxygen uptake per kilogram of weight and heart rate. The aim of the study is to contribute to determine whether there is a more energy-intensive endurance running with an impact on the rearfoot or the impact on the forefoot. In this article, we focus on two important factors affecting running economy - minute oxygen uptake and minute oxygen uptake per kilogram of weight. Statistically significant difference (p < 0.05) the forefoot and rearfoot was in oxygen uptake. The average value rearfoot of minute oxygen uptake of 0.114 l.min-1 is below than forefoot. We conclude that rearfoot is more economical than forefoot. From the measured 15 runners, we cannot clearly say whether running rearfoot or forefoot is more economical. |
