As we grow older, our muscular function declines. A new study by researchers at Karolinska Institutet in Sweden shows how an unexpectedly high number of mutations in the stem cells of muscles impair cell regeneration. This discovery may result in new medication to build stronger muscles even when in old age. The study is published in Nature Communications.
Contrary to previous studies and widespread belief, new research on competitive judo data finds a winning bias for the athlete who is first called, regardless of the color of their uniform.
The more you see your friends post about exercise on social media, the worse you might feel about your own weight, especially when you perceive those people as being very similar to you, new research suggests. However, certain people -- those who tend to make 'upward social comparisons' -- find their friends' workout posts motivating.
Spending too much time in front of the television could increase your chance of developing potentially fatal blood clots known as venous thrombosis. Even trying to counterbalance hours of TV watching through adequate exercise is not effective warns Yasuhiko Kubota of the University of Minnesota in the US. Kubota is the lead author of a study in Springer's Journal of Thrombosis and Thrombolysis.
The research shows that female students do it for health reason and male students do it for social relationships that are involved in doing sport. Among those who had stopped doing or never done sport, a lack of time was the main reason.
If you don't have the time or money for aerobic and resistance training, why not try climbing the stairs? A new study demonstrates that stair climbing not only lowers blood pressure but also builds leg strength, especially in postmenopausal women with estrogen deficiencies who are more susceptible to vascular and muscle problems. The study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).
Exercise has numerous, well-documented health benefits. Could it also play a role in preventing and reducing substance misuse and abuse in adolescents? In a review article recently published in Birth Defects Research, researchers supply a rationale for the use of exercise, particularly assisted exercise, in the prevention and adjunctive treatment of substance-use disorders.
A MassGeneral Hospital for Children study finds that children participating in a 12-week, before-school physical activity program experienced improvement in body weight and social/emotional wellness, compared with their classmates who did not participate.
Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn't do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. Cognitive biologists from Vetmeduni Vienna propose computer interaction as a practical alternative.
Being taught science subjects outdoors increases student motivation. A study by the Technical University of Munich (TUM) and the University of Mainz therefore suggests offering more outdoor instruction at the lower secondary level.
