The effect of pre‐exercise hyperventilation on repeated high‐intensity inclined sprint performance

Experimental Physiology, Volume 111, Issue 7, Page 3412-3424, 1 July 2026.
Abstract High‐intensity exercise induces systemic acidosis, which contributes to muscular performance decline. Controlled pre‐exercise hyperventilation has been proposed as a non‐invasive intervention to induce respiratory alkalosis and counteract acidosis‐related acute fatigue.

Effects of chemical myosin II cross‐bridge inhibitors on eccentric force production in skinned muscle fibres

Experimental Physiology, Volume 111, Issue 7, Page 3337-3356, 1 July 2026.
Abstract Eccentric muscle contractions are essential for locomotion and daily activities. Force during these contractions depends on both cross‐bridge (XB) and non‐cross‐bridge (non‐XB) elements, including titin, with contributions varying by fibre type and contraction velocity.

A microstructurally motivated framework to study autoregulation in the coronary circulation

The Journal of Physiology, Volume 604, Issue 14, Page 5892-5925, 15 July 2026.
Abstract figure legend A microstructurally motivated framework was constructed to simulate coronary autoregulation in symmetrically bifurcating trees at three myocardial depths: subepicardial (subepi), midwall and subendocardial (subendo). Wall mechanics of individual vessels are governed by a constrained‐mixture model, incorporating elastin, collagen ...

Muscle residual force enhancement: a brief review

Clinics, 2013
Muscle residual force enhancement has been observed in different muscle preparations for more than half a century. Nonetheless, its mechanism remains unclear; to date, there are three generally accepted hypotheses: 1) sarcomere length non-uniformity, 2 ...
