Discus and javelin throwers as well as marathon runners and race walkers are likely to achieve their best performances at a later age than sprinters, hurdlers and middle-distance runners. Why? It comes down to muscle fibres and technique.
UCLA researchers have identified a compound that can reproduce the effect of exercise in muscle cells in mice. The findings are published today in the journal Cell Reports Medicine.
Research in sheep suggests that high levels of a stress hormone during pregnancy may alter gene expression in multiple muscle groups of offspring. These shifts may affect heart, breathing and skeletal muscle function, and could potentially increase risks of inflammation and infection. The study is published ahead of print in Physiological Genomics.
A study from St. Jude Children’s Research Hospital sheds light on the mechanisms governing feeding behavior in fruit flies and how skeletal muscle communicates energy needs to the brain.
