Microstructural Brain Reserve Moderates the Associations Between 24‐h Movement Behaviors and Cognition in Older Adults: Cross‐Sectional Findings From the AGUEDA Trial

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 9, September 2026.
ABSTRACT This study examined the associations between 24‐h movement behaviors and cognitive function in cognitively unimpaired older adults, and whether Alzheimer's disease brain signatures, including gray matter mean diffusivity (GMMD) and thickness/volume signatures, moderated these associations. A total of 91 participants were enrolled in the AGUEDA

Clustering analysis of acute mountain sickness susceptibility among young adults during rapid ascent using low‐altitude step test data

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract Acute mountain sickness (AMS) compromises health and work efficiency after rapid ascent. This study aimed to explore a low‐altitude‐data‐based method for classifying AMS‐susceptible young adults. Forty‐four low‐altitude residents (18–31 years) completed a step test at 50 m.

Nocturnal peak in cardiac baroreflex effectiveness aligns with nocturnal trough in systolic blood pressure in young healthy adults: Possible circadian effects

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract We tested whether there is a circadian variation in baroreflex function measured as sensitivity and effectiveness, and whether it aligned with circadian variations in systolic blood pressure (BP). Eleven healthy adults (24 ± 2 years; 4 males and 7 females) completed a 30‐h circadian protocol incorporating five recurring, identical, 6‐h cycles ...

Construct validity of the international physical activity questionnaire using accelerometry data in patients with femoroacetabular impingement Syndrome and Acetabular Dysplasia: a cross-sectional analysis

BMC Musculoskeletal Disorders
Background The International Physical Activity Questionnaire (IPAQ) is widely used to assess physical activity (PA), but its validity compared to device-measured PA data in patients with Femoroacetabular Impingement Syndrome (FAIS) and Acetabular ...

Subjective Estimation of Physical Activity Using the IPAQ Varies by Fitness Level [PDF]

, 2015
Background: Subjective measures of moderate and vigorous physical activity (MVPA) rely on ‘relative’ intensity while objective measures capture ‘absolute’ intensity, thus fit individuals may perceive the same activity differently than unfit individuals ...
