STOP THE PRICKS: A VALIDATION STUDY OF A NONINVASIVE LACTATE THRESHOLD DEVICE

<p>ABSTRACT</p> <p>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).</p> <p>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.</p> <p>Results: No significant differences were found in lactate threshold heart rate and the aerobic threshold heart rate between the noninvasive device and four traditional lactate methods.</p> <p>Conclusions: This study provides preliminary support for the validity of the NID for estimation of LTHR (4mmol), but weaker support for validity at AeTHR (2mmol). </p>
