By injecting cells that support blood vessel growth into muscles depleted by inactivity, researchers say they are able to help restore muscle mass lost as a result of immobility.
A new Canadian study of more than 2,400 families suggests that among preschoolers, spending two hours or more of screen time per day is linked to clinically significant behavioural problems.
A six-week transition period did not help wearers adjust to "maximal" running shoes, indicating that increased impact forces and loading rates caused by the shoe design do not change over time.
Researchers from Children's Hospital Colorado and the University of Colorado School of Medicine in Aurora, Colorado, have found that abnormal performance on the Romberg balance test can indicate that children and adolescents will experience prolonged symptoms following sports-related concussion.
In a study of healthy volunteers, National Institutes of Health researchers found that our brains may solidify the memories of new skills we just practiced a few seconds earlier by taking a short rest. The results highlight the critically important role rest may play in learning.
A review led by a sports scientist at the University of Stirling has set out new international guidelines for protein intake in track and field athletes.
In the first North American stem cell clinical trial for osteoarthritis of the knee patients, 12 patients were given injections of their own stem cells and followed for 12 months. The results show a significant improvement in pain levels and quality of life.
Researchers at the University of North Carolina at Chapel Hill and partners have found strong evidence that rates of heat-related illnesses, such as heat cramps and heat strokes, were reduced by half in states that had mandated guidelines to reduce exertional heat illness among high school football players. This is one of the first studies examining the effectiveness of state-mandated guidelines for reducing exertional heat illness among high school football players.
People who engage in high-intensity interval training are at greater risk for injury, especially in the knees and shoulders, a Rutgers study found.
In a new study conducted in rats, researchers found a four-week period of rest was nearly as effective as an experimental drug at reducing discomfort and regaining function after an injury from repeated moderate-strain activity. The findings are relevant to treating common musculoskeletal disorders caused by overuse, such as carpal tunnel syndrome, tendinitis, tendinosis and low back pain.
