Predicting Sleep and Sleep Stage in Children Using Actigraphy and Heartrate via a Long Short‐Term Memory Deep Learning Algorithm: A Performance Evaluation

open access: yesJournal of Sleep Research, Volume 35, Issue 1, February 2026.
ABSTRACT Children's ambulatory sleep is commonly measured via actigraphy. However, traditional actigraphy measured sleep (e.g., Sadeh algorithm) struggles to predict wake (i.e., specificity, values typically < 70) and cannot predict sleep stages. Long short‐term memory (LSTM) is a machine learning algorithm that may address these deficiencies.

Low‐Load Blood Flow Restriction Training Enhances Brachial Blood Flow During Exercise but not Reactive Hyperemia in Experienced Climbers

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Low‐load blood flow restriction training (LLBFRT) induces significant vascular stress, which is often associated with vascular remodeling, increased capillarization and muscle blood flow. These adaptations may be of interest to climbers as their endurance performance is limited by blood supply due to the isometric and intermittent nature of ...

Effects of 12 weeks of upper‐body rowing exercise on autonomic cardiovascular control and vascular structure in spinal cord‐injured humans

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 375-389, 1 February 2026.
Abstract Spinal cord injury (SCI) is characterized by autonomic cardiovascular dysfunction that may contribute to the three‐ to fourfold greater risk of heart disease and stroke compared to non‐injured individuals. While exercise training elicits beneficial changes in autonomic function and vascular structure in healthy individuals, it is unclear if ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 527-538, 1 February 2026.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...
