Diffusion and physical constraints limit oxidative capacity, capillary supply and size of muscle fibres in mice and humans

open access: yesExperimental Physiology, EarlyView.
Abstract It has been suggested that angiogenesis during skeletal muscle fibre hypertrophy allows escape from the ‘size constraint’, which is the inverse relationship between oxidative capacity and muscle fibre cross‐sectional area (FCSA). It is, however, not known whether there are any limitations to the combinations of FCSA, oxidative capacity and ...

Bioavailable testosterone and androgen receptor activation, but not total testosterone, are associated with muscle mass and strength in females

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐seven pre‐menopausal, untrained females performed a 12‐week resistance training programme to explore the association between androgen concentrations, androgen receptor signalling and skeletal muscle size and strength. Total testosterone was not associated with muscle mass or strength, nor with resistance training‐induced ...

Previous short‐term disuse dictates muscle gene expression and physiological adaptations to subsequent resistance exercise

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Eleven young healthy males underwent 10 days of unilateral lower limb suspension (ULLS) followed by a 21 day period of active recovery (AR) using resistance exercise performed three times a week at 70% of the one repetition maximum (1RM), equating to a total of nine training sessions.

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...
