Aerometabolic Economy Of Long Distance Run Using The Forefoot And Rearfoot Style
Vol.8,No.1(2014)
The research project focuses on the problem of the optimum cross step in long distance running. Step should be energetically most favourable – economics. We want to answer the question whether and under what conditions the forefoot and rearfoot impact is energetically preferable to endurance running pace. Tested subjects were 15 athletes. Athletes held a running pace of 12 km.h-1 . When we evaluated the results, we focused on indicators of 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 more energy-intensive endurance running when 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 differences (p < 0.05) of the forefoot and rearfoot impact was in oxygen uptake. The average value rearfoot of minute oxygen uptake of 0.114 l.min-1 is below than forefoot. We concluded that rearfoot is more economical than forefoot. From the measured 15 runners, we cannot clearly say whether running rearfoot or forefoot is more economical.
