Altered Skeletal Muscle Phosphate Metabolism After Muscle Damage Is Associated With Elevated Effort Perception During Exercise in Humans

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 8, August 2026.
ABSTRACT It remains unclear why exercising damaged muscles is perceived as disproportionately more effortful. Given the known role of inorganic phosphate (Pi) in fatigue and afferent sensory signaling, we tested whether muscle damage disrupts phosphate metabolism and whether this is associated with heightened ratings of perceived exertion (RPE ...

Phosphate and acidosis cause fibre type‐specific changes to cellular and molecular contractile mechanics at 37°C in skeletal muscle from older adults

Experimental Physiology, Volume 111, Issue 8, Page 3753-3771, 1 August 2026.
Abstract Intracellular accumulation of hydrogen ions (H+) and inorganic phosphate (Pi) has temperature‐dependent effects on single‐fibre contractile function between 10°C and 30°C. In vivo, human skeletal muscle temperatures range between 35‐39°C, and although contractile function is highly dependent on temperature, the effects of fatigue‐inducing [H+]

Strategies for the Selection and Application of Biological Scaffolds in Organ‐on‐a‐Chip Systems

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Organ‐on‐a‐chip (OoC) serves as a promising microphysiological platform for drug screening, disease modeling, and toxicity assessment. Biomimetic scaffolds are core components that determine the performance of OoC systems by mimicking the in vivo extracellular microenvironment.
