Generation and modification of human locomotor EMG activity when walking faster and carrying additional weight

Experimental Physiology, EarlyView.
Abstract In activities of daily living, people walk at different speeds with or without carrying additional loads. In this study, we sought to examine how human adults manage these commonly encountered additional demands during walking. We measured electromyography (EMG), triceps surae H‐reflexes, joint motion and ground reaction forces (GRF) while ...

High‐intensity resistance training and collagen supplementation improve patellar tendon adaptations in professional female soccer athletes

Experimental Physiology, EarlyView.
Abstract We investigated whether 10 weeks of pre‐season soccer training (including high‐intensity resistance exercise) with hydrolysed collagen (COL) supplementation would confer greater changes in patellar tendon (PT) mechanical and material properties compared with placebo (PLA) in professional female soccer athletes.

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

Experimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

Eccentric training at long muscle lengths induces greater corticospinal and spinal reflex plasticity than eccentric training at short muscle lengths

Experimental Physiology, EarlyView.
Abstract It is well‐established that resistance training generates neural adaptations. These may be greater when exercises mainly include eccentric contractions or when muscles are trained at long length. However, it remains to be clarified whether the length at which muscles are trained influences neural adaptation following eccentric training.

Weighted cart pull: A novel outcome measure for sustained motor function in mice

Experimental Physiology, EarlyView.
Abstract Sarcopenia, the pathological age‐related decline in muscle mass and strength, compromises independence and quality of life in older adults. Currently, no effective treatments are available. To enhance translational research using aged mouse models, we developed and validated the weighted cart pull (WCP) as a novel assessment of sustained motor

Inhibition and potentiation of the exercise pressor reflex by pharmacological modulation of TRPC6 in male rats

The Journal of Physiology, EarlyView.
Abstract figure legend The majority of L4–L5 dorsal root ganglion cells innervating the triceps surae muscles of healthy rats expressed TRPC6 channels. In decerebrated rats, pharmacological inhibition of TRPC6 channels by injection of antagonists (SAR7334 or BI‐749327) into the arterial supply of the triceps surae muscles inhibited the exercise pressor

Lactate and hydrogen ions play a predominant role in evoking the exercise pressor reflex during ischaemic contractions but not during freely perfused contractions

The Journal of Physiology, EarlyView.
Abstract figure legend The role of lactate and hydrogen ions in evoking the metabolic component of the exercise pressor reflex was studied in rats with either a functional pygm gene (pygm+/+) or with a non‐functional “knocked out” pygm gene (pygm−/−). The pygm gene is responsible for producing the myophosphorylase enzyme which catalyses the breakdown ...

Load and muscle‐dependent changes in triceps surae motor unit firing properties in individuals with non‐insertional Achilles tendinopathy

The Journal of Physiology, EarlyView.
Abstract figure legend Motor unit firing properties of the medial gastrocnemius (MG), lateral gastrocnemius (LG), and soleus (SO) muscles were assessed using high‐density surface electromyography (HD‐sEMG) during isometric plantarflexion contractions at 10%, 40%, and 70% maximal voluntary contraction (MVC) in individuals with non‐insertional Achilles ...

Exploring cellular changes in ruptured human quadriceps tendons at single‐cell resolution

The Journal of Physiology, EarlyView.
Abstract figure legend This study explores the cellular landscape of healthy and ruptured quadriceps tendons using single nucleus RNA sequencing. While a range of stromal and immune cell types and subsets were identified, the data indicate that fibroblasts and endothelial cells are the main drivers of the early injury response within ruptured ...

Muscle Strengthening Exercises for the Foot and Ankle: A Scoping Review Exploring Adherence to Best Practice for Optimizing Musculoskeletal Health

Journal of Foot and Ankle Research, Volume 18, Issue 2, June 2025.
ABSTRACT Background Foot and ankle muscle strengthening exercises are common interventions for many musculoskeletal conditions that are associated with pain and limited function in the lower limb. The scientific literature has a multitude of strengthening exercises recommended, and they have been criticized for not adhering to best practice and for ...
