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 ...

A nitric oxide synthase transgene ameliorates muscular dystrophy in mdx mice. [PDF]
, 2001 Dystrophin-deficient muscles experience large reductions in expression of nitric oxide synthase (NOS), which suggests that NO deficiency may influence the dystrophic pathology.

The multifaceted roles of ketones in physiology
Experimental Physiology, EarlyView.Abstract The production of ketones, referred to as ketogenesis, plays an essential role in maintaining energy homeostasis during prolonged fasting/starvation, which primarily stems from its ability to serve as a fuel source to support neuronal ATP production, thereby limiting muscle wasting. Over the years, the field has come to appreciate that ketones

The evolution of muscle spindles
Experimental Physiology, EarlyView.Abstract Muscle spindles are stretch‐sensitive mechanoreceptors found in the skeletal muscles of most four‐limbed vertebrates. They are unique amongst sensory receptors in the ability to regulate their sensitivity by contraction of the intrafusal muscle fibres on which the sensory endings lie.

Experimental Physiology, EarlyView.Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Brazilian Journal of Medical and Biological Research, 2010 Angiotensin-converting enzymes 1 (ACE1) and 2 (ACE2) are key enzymes of the renin-angiotensin system, which act antagonistically to regulate the levels of angiotensin II (Ang II) and Ang-(1-7).

Current Research in Physiology, 2020 Lactate is not merely a metabolic intermediate that serves as an oxidizable and glyconeogenic substrate, but it is also a potential signaling molecule. The objectives of this study were to investigate whether lactate administration enhances post-exercise

Experimental Physiology, EarlyView.Abstract We review our approach for undertaking microelectrode recordings from the posterior tibial nerve at the ankle, which has allowed us to identify, for the first time, the firing properties of muscle spindle endings in the intrinsic muscles of the foot and of cutaneous mechanoreceptors in the sole during unsupported standing.
