Adaptation of muscle tissue to aerobic exercise alters the metabolism of muscle stem cells, helping them recover from injury. Findings may contribute to treatment of cachexia, sarcopenia and other conditions associated with lean mass loss.
Trinity College Dublin researchers have carried out the first multi-centred, international, qualitative study exploring the athlete experience (in their own words) of sporting low back pain (LBP). The study published in the British Journal of Sports Medicine found a culture of concealment of pain and injury in rowers, leading to poor outcomes for these athletes.
Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice. This was not observed in male mice that lacked the ERβ gene, suggesting that estrogen and its downstream signals may be a female-specific mechanism for muscle growth and regeneration.
Athletes using legal performance enhancing and medical sport supplements are more likely to dope than those using sport foods and superfoods, a new study reveals.
A new Danish study from the Department of Sports Science and Clinical Biomechanics at the University of Southern Denmark recently showed, that if athletes can place their glycogen close to the structures that produce the force in the muscle cells, they can cycle for a longer time, than if their glycogen is placed elsewhere in the muscle cells. In other words, the research results suggest that it is more important where the sugar is stored than how much there is.
The small blood vessels in muscles of women after menopause are less able to grow compared to young women, according to new research published today in the Journal of Physiology. This means exercising before menopause is all the more important for women in order to develop blood vessels in muscles, and thus the ability to develop muscle strength.
Determining whether high-intensity interval training (HIIT) is an appropriate form of exercise for the average person has been hotly debated for years. But for one UBC Okanagan researcher, there's not much to debate--interval exercise, when used appropriately, can fit into people's menu of flexible exercise options.
Brazilian researchers use complex training program to stimulate different motor and cognitive skills simultaneously and restore brain regions associated with freezing of gait in advanced-stage patients.
A new study of NCAA football players has found that the age they first started playing tackle football may not affect their recovery after a concussion. The study is published in the September 9, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A new study published in the journal Pediatrics found that young adults aged 18-26 who used legal performance-enhancing substances were significantly more likely to report several problematic alcohol use and drinking-related risk behaviors seven years later. This relationship was especially strong among men.
