Physical Activity in Children and Young Adults With Cerebral Palsy: Results From a Three‐Month Exercise Intervention Open
Individuals with cerebral palsy (CP) are suggested to be less active than typically developing controls (TDs). However, their higher physical activity (PA) energy expenditure during a given activity should be considered. We investigated PA…

The impact of varying small-sided games’ pitch sizes on replicating official match physical demands during effective playing time in male professional soccer players Open
Small-sided games (SSGs) are commonly used to replicate or overload official match (OM) demands in soccer, yet they often fail to replicate OM locomotor loads (distance at various speeds). This study examined whether increasing SSGs pitch …

Use it or lose it: A four-year follow-up to assess whether engagement with physical activity close to one's physical capacity may protect against decline in physical functioning among older adults Open
PURPOSE: Physical activity (PA) is distinct from physical capacity (PC), even though they are correlated in old age. PC defines the limits for PA, while activities in daily life typically remain submaximal. Individuals whose intensity of d…
