In the 1960s Professor Setsuro Ebashi, a physiologist from the University of Tokyo, discovered calcium ion plays a pivotal role in muscle contraction for the first time. However, he was confounded by icy neglect of the society of physiologists. The International Conference on Physiology was held in Boston in 1962, and Dr. Ebashi and his coworker Dr. Anne Mary Weber gave a talk about calcium signal which is a key mechanism for regulating muscle contraction. Every single attendant stood against their theory and even laughed at them.

Post-exercise neural plasticity is augmented by adding blood flow restriction during low work rate arm cycling.
Exp Physiol
January 2025
Centre for Healthy Ageing, Health Futures Institute, Murdoch University, Perth, Australia.
Blood flow restriction (BFR) combined with low work rate exercise can enhance muscular and cardiovascular fitness. However, whether neural mechanisms mediate these enhancements remains unknown. This study examined changes in corticospinal excitability and motor cortical inhibition following arm cycle ergometry with and without BFR.

The kinases AMPK, and mTOR as part of either mTORC1 or mTORC2, are major orchestrators of cellular growth and metabolism. Phosphorylation of mTOR Ser1261 is reportedly stimulated by both insulin and AMPK activation and a regulator of both mTORC1 and mTORC2 activity. Intrigued by the possibilities that Ser1261 might be a convergence point between insulin and AMPK signaling in skeletal muscle, we investigated the regulation and function of this site using a combination of human exercise, transgenic mouse, and cell culture models.

College of Rehabilitation Medicine, Fujian University of Traditional Chinese Medicine, Fuzhou, China.
Objective: Lumbo-pelvic-hip complex muscle training is considered a crucial component of exercise rehabilitation for postpartum women with pelvic girdle pain (PGP). However, there is a paucity of research evidence regarding the morphological changes and contraction function of these muscles in postpartum women with PGP. Understanding the alterations in lumbo-pelvic-hip complex muscles function associated with PGP, is crucial for tailoring effective rehabilitation strategies and promoting optimal postpartum recovery.

Duchenne muscular dystrophy (DMD) is an X-linked muscle disease with weakness, loss of ambulation, and premature death. DMD patients have reduced bone health, including decreased femur length (FL), density, and fractures. The mouse model has paradoxically greater FL, density, and strength, positively correlating with muscle mass.

Background: Vascular calcification (VC) commonly occurs in diabetes and is associated with cardiovascular disease incidence and mortality. Currently, there is no drug treatment for VC. The Danlian-Tongmai formula (DLTM) is a traditional Chinese medicine (TCM) prescription used for diabetic VC (DVC), but its mechanisms of action remain unclear.
