Absolute and relative physical activity intensity thresholds across diverse fitness levels: A cross-sectional study in middle-aged women
Introduction Physical activity (PA) intensity can be expressed in absolute terms (metabolic equivalents, METs) or relative to individual capacity (percentage of maximal oxygen consumption, VO2max), and these two approaches yield markedly different interpretations of health-related PA. This study examined how time spent at absolute and relative PA intensities relates to cardiorespiratory fitness (CRF) in middle-aged women across a wide fitness ran…
Case Report: Unilateral resistance and impact loading during knee rehabilitation after grade-2 MCL injury was associated with hip-specific aBMD accrual in an elite female road cyclist
Background: Low areal bone mineral density (aBMD) is prevalent in elite road cyclists due to non-weight-bearing training loads and, at times, low energy availability (EA). Real-world, site-specific skeletal responses to targeted loading during rehabilitation remain insufficiently characterized. Case presentation: A 24-year-old WorldTour-level female road cyclist with low aBMD (Z-score ≤ -1.1) initiated a periodized resistance and impact loading p…
Physical activity partially mediating the social gradient in adolescent mental health
Objectives: To examine whether there is a socioeconomic status (SES) gradient in adolescent mental health problems, and if so, whether out-of-school physical activity mediates this gradient. Methods: Based on data from 1,285 adolescents in Sweden, we used linear regression analysis to examine whether the social gradient in mental health problems (stress and psychosomatic symptoms by survey) varied by SES indicators, including income, father's and…

Accelerometer-measured absolute versus relative physical activity intensity: Cross-sectional associations with cardiometabolic health in midlife
Accelerometer-measured relative physical activity intensity represents the intensity related to health benefits regardless of fitness level. Traditional absolute moderate intensity accelerometer cut-offs are too low for most individuals and should be adapted to the fitness level in the sample studied. Absolute and relative physical activity intensity cannot be used interchangeably
The interrelationship between physical activity intensity, cardiorespiratory fitness, and executive function in middle-aged adults: An observational study of office workers
Background: Previous evidence supports a beneficial effect of physical activity on executive function across the whole lifespan. Yet, the interrelationships of the intensities of physical activity, cardiorespiratory fitness, and executive function require further investigation in adults. Aim: Using unfiltered accelerometry data and high-resolution intensity classification, we sought to estimate the associations of physical activity with cardiores…
Effects of Two Randomized and Controlled Multi-Component Interventions Focusing On 24-Hour Movement Behavior among Office Workers: A Compositional Data Analysis
Intervention studies aiming at changing movement behavior have usually not accounted for the compositional nature of time-use data. Compositional data analysis (CoDA) has been suggested as a useful strategy for analyzing such data. The aim of this study was to examine the effects of two multi-component interventions on 24-h movement behavior (using CoDA) and on cardiorespiratory fitness among office workers; one focusing on reducing sedentariness…
The use of coping strategies “shift-persist” mediates associations between physical activity and mental health problems in adolescents: A cross-sectional study
Leisure time physical activity, irrespective of intensity, may facilitate successful coping with stress and stress-related mental health problems in adolescents
