Abstract

[Purpose] An easy method to determine the anaerobic threshold (AT) is required. The aim of this study was to determine AT by heart rate (HR) square methods and to collect basic data. Moreover, we compared AT determined by the V-slope method and the double product break point (DPBP) method, and investigated the utility of (HR)2 methods. [Subjects] The subjects were 10 healthy adult men (23.8 ± 2.5 years old). [Methods] After resting in a seated position for 5 min and 0 watt warm-up for 3 min, the subjects performed a ramped exercise load test on a bicycle ergometer starting with 30 watts and increasing by 10 watts every 2 min. [Results] There was no significant difference in VO2 and watts when AT was determined by (HR)2, DPBP and V-slope methods. [Conclusion] The results suggest that the (HR)2 method is one of easiest ways to find HR and load to determine AT.<br>
