Researchers have long been aware that the progressive loss of muscle mass and bone density is a natural part of aging. But little work has investigated how muscle tissue affects the inner and outer layers of bone microstructure. A Mayo Clinic study looked at skeletal muscle mass and bone health across the life span and discovered distinct differences in how muscle affects the two layers of bone in men and women.
Triclosan, an antibacterial chemical widely used in hand soaps and other personal-care products, hinders muscle contractions at a cellular level, slows swimming in fish and reduces muscular strength in mice, according to researchers at the University of California, Davis, and the University of Colorado.
A study carried out by Dr. Louis Bherer, PhD (Psychology), Laboratory Director and Researcher at the Institut universitaire de gériatrie de Montréal (IUGM), an institution affiliated with Université de Montréal, has shown that all seniors, even those considered frail, can enjoy the benefits of exercise in terms of their physical and cognitive faculties and quality of life and that these benefits appear after only three months.
An international team of scientists have identified for the first time a key factor responsible for declining muscle repair during aging, and discovered how to halt the process in mice with a common drug. Although an early study, the findings provide clues as to how muscles lose mass with age, which can result in weakness that affects mobility and may cause falls.
A new study to be presented at the Society for Experimental Biology meeting on 30th June has shown that caffeine boosts power in older muscles, suggesting the stimulant could aid elderly people to maintain their strength, reducing the incidence of falls and injuries.
Some athletes may improve their performance under pressure simply by squeezing a ball or clenching their left hand before competition to activate certain parts of the brain, according to new research published by the American Psychological Association.
