A new Finnish study, published in the journal Frontiers in Microbiology, finds that endurance exercises may change the composition of gut microbiota.
The researchers developed a 6-week program of bicycle training and enrolled 17 overweight women for this program. All women led a sedentary lifestyle before joining the study.
At the end of the program, the scientists noticed that the number of proteobacteria, gut bacteria that cause inflammation, decreased and the number of beneficial bacteria Akkermansia, linked to better metabolism, increased.
The corresponding author of the study Satu Pekkala, an Academy of Finland research fellow affiliated with the Faculty of Sport and Health Sciences of the University of Jyväskylä, explains: “These changes are beneficial for cardiometabolic health, because VLDL transports lipids from the liver to peripheral tissues, converts into ‘bad’ LDL [low-density lipoprotein] cholesterol in the circulation, and thus has detrimental cardiovascular effects.”
According to a recent study, completed by the scientists from the Duke University Medical Center in Durham, USA, regular bedtime is important for heart health and metabolism.
A team of scientists examined the sleeping patterns of approximately 2,000 adults aged between 54 and 93. None of them had a history of sleep disorders. Having analyzed the received data, the researchers found that volunteers with irregular bedtime had a higher body mass index, the higher level of blood sugar and blood pressure, as well as increased levels of hemoglobin A1C.
The lead researcher Jessica Lunsford-Avery, Ph. D., an assistant professor in psychiatry and behavioral sciences from the Duke University Medical Center, says: “Heart disease and diabetes are extremely common in the United States, are extremely costly and also are leading causes of death in this country. To the extent we can predict individuals at risk for these diseases, we may be able to prevent or delay their onset.”
A recent study finds how exercise changes metabolism and helps make it more efficient. The researchers looked at how cells work during exercise and found that exercising converts the type of fat cells we have changing them from metabolically inactive ‘white fat’ to ‘brown fat’ that burns more calories.
Scientists believe that all superpowers of exercising deal with a hormone called irisin, which is produced during the exercise stress.
Li-Jun Yang, a professor of hematopathology in the University of Florida College of Medicine’s department of pathology and a study author, says: “We all know regular exercise is good for our health. But our work provides [additional] direct biological explanations or mechanisms why people who regularly exercise can maintain lean bodies and stronger bone structure.”
