ABSTRACT
Purpose: The aim of this study is to assess the validity of a noninvasive lactate threshold device (NID) to determine lactate threshold heart rate (LTHR) and aerobic threshold heart rate (AeTHR).
Methods: Twenty-one recreational athletes completed a personalized graded exercise test on a treadmill. All participants wore the noninvasive device and blood lactate samples were taken at the end of 3-minute stages. Lactate threshold heart rate and aerobic threshold heart rate were then calculated using four traditional methods and compared against the same heart rate values calculated by the device.
Results: No significant differences were found in lactate threshold …
