BMC Public Health
. 2025 Mar;
25(1):885.
PMID: 40050804
Background: To investigate whether quantifying both the absolute and relative intensity of physical activity (PA) improves understanding of age, sex, and occupation-related differences in PA in healthy adults aged 20-89....

Int J Sports Physiol Perform
. 2025 Jan;
20(3):345-354.
PMID: 39778576
To define training zones, ventilatory thresholds (VTs) are commonly established by cardiopulmonary gas-exchange analysis during incremental exercise tests. Portable near-infrared spectroscopy (NIRS) devices have emerged as a potential tool for...

Sci Rep
. 2024 Oct;
14(1):25848.
PMID: 39468229
Coronary artery disease (CAD) remains a leading cause of death worldwide and imposes a substantial socioeconomic burden on healthcare. Improving risk stratification in clinical practice could help to combat this...

Eur J Prev Cardiol
. 2024 Sep;
32(1):10-19.
PMID: 39276370
Aims: To investigate how physical activity (PA) volume, intensity, duration, and fragmentation are associated with the risk of all-cause and cardiovascular disease mortality. To produce centile curves for PA volume...

Int J Sports Physiol Perform
. 2024 Jun;
19(8):780-791.
PMID: 38849121
Objective: To (1) establish extensive physiological profiles of highly trained CrossFit® athletes using gold-standard tests and (2) investigate which physiological markers best correlate with CrossFit Open performance. Methods: This study...

Gait Posture
. 2024 Jan;
109:101-108.
PMID: 38290395
Background: Gait changes with aging have been investigated, but few studies have examined a wide range of gait parameters across the adult lifespan. This study aimed to investigate gait differences...

Eur J Appl Physiol
. 2024 Jan;
124(6):1669-1681.
PMID: 38238521
Purpose: The objective was to investigate if performing a sub-peak or supra-peak verification phase following a ramp test provides additional value for determining 'true' maximum oxygen uptake ( O). Methods:...

Med Sci Sports Exerc
. 2023 Sep;
56(2):170-180.
PMID: 37703330
Purpose: Accelerometer-assessed physical activity (PA) can be summarized using cut-point-free or population-specific cut-point-based outcomes. We aimed to 1) examine the interrelationship between cut-point-free (intensity gradient (IG) and average acceleration (AvAcc))...

Med Sci Sports Exerc
. 2023 Sep;
56(2):159-169.
PMID: 37703323
Introduction: Well-trained staff is needed to interpret cardiopulmonary exercise tests (CPET). We aimed to examine the accuracy of machine learning-based algorithms to classify exercise limitations and their severity in clinical...
