Michigan Medicine researchers studying a class of naturally occurring protein called Sestrin have found that it can mimic many of exercise’s effects in flies and mice. The findings could eventually help scientists combat muscle wasting due to aging and other causes.

“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” said Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology. Kim, working with professor Jun Hee Lee, Ph.D. and a team of researchers wanted to know more about the protein’s apparent link to exercise. Their first step was to encourage a bunch of flies to work out.

Taking advantage of Drosophila flies’ normal instinct to climb up and out of a test tube, their collaborators Robert Wess...

A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building to a greater extent than milk protein.

The study evaluated the digestion of protein, which allows amino acids (the building blocks of protein) to increase in the bloodstream and then become available for muscle protein building in 20 healthy, trained young men at rest and following a bout of strenuous resistance exercise.

The young men performed the exercise and were then given either milk protein or mycoprotein. Their muscle building rates were then measured using stable isotope labelled “tracers” in the hours following protein consumption.

Animal proteins like milk are an exce...

Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.

For a long time, the focus on exercise has been on the positive changes in the body that occur following a longer period of training. However, these findings suggest that the effects following a single session of HIIT, an exercise regime involving short, high energy bursts are also important...

Six-Week Endurance Exercise Alters Gut Metagenome That Is not Reflected in Systemic Metabolism in Over-weight Women. Frontiers in Microbiology, 2018; 9 DOI: 10.3389/fmicb.2018.02323

According to recent research, endurance exercise training beneficially modifies gut microbiota composition. After six weeks of training, potentially inflammation causing microbes (Proteobacteria) decreased and microbes that are linked to enhanced metabolism (Akkermansia) increased. Even though there was no significant drop in the weight of the subjects, exercise had other beneficial health effects, says Academy of Finland research fellow Satu Pekkala from the Faculty of Sport and Health Sciences of the University of Jyväskylä.

“We found that phospholipids and cholesterol in VLDL particles decreased in respons...
