Contrary to popular belief, a position played in collision sports like football and hockey may not raise an athlete's risk for developing brain disease later, a new study finds. Researchers also found no link between the length of their career, and their risk of degenerative brain disease, according to a study published in the February 24, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers report that 4-6-year-old children who walk further than their peers during a timed test - a method used to estimate cardiorespiratory health - also do better on cognitive tests and other measures of brain function. Published in the Journal of Clinical Medicine, the study suggests that the link between cardiorespiratory fitness and cognitive health is evident even earlier in life than previously appreciated.
Women who received physical therapy after undergoing a cesarean section had significantly improved outcomes compared to those who did not according to a new study from University of Missouri Health Care.
Almost one in five people lacks the protein α-actinin-3 in their muscle fibre. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibres, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibres. The results are published in the scientific journal The American Journal of Human Genetics.
Researchers at the University of Copenhagen confirm that the hormone GDF15 is released in response to vigorous exercise, but likely not in sufficient quantity to affect behavior or appetite. These findings add nuance to a hormone that is currently under scrutiny for its potential as an anti-obesity medication.
In the inky blackness of space an invisible threat is ever present - radiation. It can have a huge array of negative effects on astronaut health, including cardiovascular disease. However, if we are ever to journey to the red planet, we will need to understand and reduce this risk. A new review charts a course through what we know about the cardiovascular risks of space radiation, and the best ways to protect space travelers.
Scent detection dogs can identify individuals infected with the COVID-19 virus according to a new article in the Journal of Osteopathic Medicine. Findings indicate the dogs could be used to screen for infections in hospitals, senior care facilities, schools, universities, airports, large sporting events or concerts.
A KU study measured marching band members' core temperatures, fluid intake and behaviors through high-tech methods to determine their risks of heat illness. Findings showed band members are just as at risk as athletes, yet seldom have access to health experts or policies to protect them.
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.
Muscle stem cells drive the tissue's growth and repair after such injuries. But growing these cells in the lab and using them to therapeutically replace damaged muscle has been frustratingly difficult. Australian researchers have discovered a factor that triggers these muscle stem cells to proliferate and heal. In a mouse model of severe muscle damage, injections of this naturally occurring protein led to the complete regeneration of muscle and the return of normal movement after severe muscle trauma.
