Abstract

Abstract:

BACKGROUND: Although the difference between running economy and in evaluating the endurance level of competitive athletes is conclusive, little research has been done on their evaluation effect in ordinary people.
OBJECTIVE: To compare the effects of running economy and maximal oxygen uptake in evaluating the aerobic endurance level of ordinary people.
METHODS: Totally 63 recruits (strictly screened to ensure that the objects meet the level of ordinary people) were enrolled as the study objects, and 5 km performance was tested. The maximal oxygen uptake and running economy were tested on indoor treadmill in an incremental load exercise mode, with the gradient as 0. As to maximal oxygen uptake test, the speed was increased gradually from 8.5 km/h until the objects were exhausted and the maximal oxygen uptake criterion was met; as to running economy test, the speed was increased from 8.5 km/h to 11.5 km/h, then the speed of 11.5 km/h was kept for 3 minutes, and the mean value of the oxygen uptake in the last 2 minutes was calculated as the running economy value. The relationship of 5 km performance to maximal oxygen uptake and running economy was analyzed and compared by Pearson correlation during statistics.
RESULTS AND CONCLUSION: There was a high-positive correlation between 5 km performance and the running economy relative value (r=0.797, P=0.000) and a low-negative correlation between 5 km performance and maximal oxygen uptake (r=-0.317, P=0.056). Besides, as step test and outdoor 800-meter or 1 000-meter running commonly used in national physique monitoring are restrained by various factors, undoubted, simple, reliable and practical RE provides a new way for accurate evaluation of national physique.
