The characterization of the transit through the anaerobic threshold based on relationships between RR and QRS cardiac intervals. [PDF]

PLoS ONE, 2019
This paper aims to develop a novel computational technique for the detection of the transit through the anaerobic threshold. This technique uses only cardiac intervals derived from the electrocardiogram and is based on algebraic relationships between RR ...

Interobserver variability of ventilatory anaerobic threshold in asymptomatic volunteers [PDF]

Multidisciplinary Respiratory Medicine, 2019
Background The ventilatory anaerobic threshold (VO2@AT) has been used in preoperative risk assessment and rehabilitation for many years. Our aim was to determine the interobserver variability of AT using cardiopulmonary exercise (CPET) data from a large ...

A novel device for detecting anaerobic threshold using sweat lactate during exercise. [PDF]

Sci Rep, 2021
The lactate threshold (LT1), which is defined as the first rise in lactate concentration during incremental exercise, has not been non-invasively and conveniently determined in a clinical setting. We aimed to visualize changes in lactate concentration in

Detection of the Anaerobic Threshold in Endurance Sports: Validation of a New Method Using Correlation Properties of Heart Rate Variability. [PDF]

J Funct Morphol Kinesiol, 2021
Past attempts to define an anaerobic threshold (AnT) have relied upon gas exchange kinetics, lactate testing and field-based evaluations. DFA a1, an index of heart rate (HR) variability (HRV) fractal correlation properties, has been shown to decrease ...

Effects of blood transfusion on exercise capacity in thalassemia major patients. [PDF]

PLoS ONE, 2015
Anemia has an important role in exercise performance. However, the direct link between rapid changes of hemoglobin and exercise performance is still unknown.To find out more on this topic, we studied 18 beta-thalassemia major patients free of relevant ...

Anaerobic threshold using sweat lactate sensor under hypoxia [PDF]

Scientific Reports, 2023
We aimed to investigate the reliability and validity of sweat lactate threshold (sLT) measurement based on the real-time monitoring of the transition in sweat lactate levels (sLA) under hypoxic exercise.

Level of performance and stability of cardiopulmonary variables in the intensity of the ventilatory anaerobic threshold [PDF]

Motriz: Revista de Educacao Fisica, 2018
AIM The aim of this study was to describe the behavior of different cardiopulmonary variables in exercise session with constant running speed, corresponding to the intensity of ventilatory anaerobic threshold and identifying the steady state in a ...

Patients' inability to perform a preoperative cardiopulmonary exercise test or demonstrate an anaerobic threshold is associated with inferior outcomes after major colorectal surgery. [PDF]

British Journal of Anaesthesia, 2013
BACKGROUND: Surgical patients with poor functional capacity, determined by oxygen consumption at anaerobic threshold (AT) during cardiopulmonary exercise testing (CPET), experience longer hospital stays and worse short- and medium-term survival. However,

Feasibility study of a novel wearable sweat sensor for anaerobic threshold determination [PDF]

Scientific Reports
Lactate anaerobic threshold has been a commonly used metric in the field of training monitoring, however its invasiveness has been overwhelming. Therefore, this study utilized sweat sensors to monitor Na+ and K+ in sweat to investigate the possibility of
