Caffeine Boosts Power For Elderly Muscles, Experts Say

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.

Eating Protein Throughout The Day Preserves Muscle, Physical Function In Dieting...

Dieting postmenopausal women who want to avoid losing muscle as they lose fat should pay attention to a new University of Illinois study. Adding protein throughout the day not only holds hunger pangs at bay so that dieters lose more weight, it keeps body composition -- the amount of fat relative to muscle -- in better proportion.

Muscle Loss In Elderly Linked To Blood Vessels’ Failure To Dilate

Why do people become physically weaker as they age? And is there any way to slow, stop, or even reverse this process, breaking the link between increasing age and frailty?

Even The Very Elderly And Frail Can Benefit From Exercise

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.

Muscle-Building Effect Of Protein Beverages For Athletes Investigated

Physical activity requires strong, healthy muscles. Fortunately, when people exercise on a regular basis, their muscles experience a continuous cycle of muscle breakdown (during exercise) and compensatory remodeling and growth (especially with weightlifting). Athletes have long experimented with methods to augment these physiologic responses to enhance muscle growth. One such ergogenic aid that has gained recent popularity is...

Too Much Glucosamine Can Cause The Death Of Pancreatic Cells, Increase...

High doses or prolonged use of glucosamine causes the death of pancreatic cells and could increase the risk of developing diabetes, according to a team of researchers at Université Laval's Faculty of Pharmacy. Details of this discovery were recently published on the website of the Journal of Endocrinology.

Antioxidants Aren’t Always Good for You And Can Impair Muscle Function,...

Antioxidants increasingly have been praised for their benefits against disease and aging, but recent studies at Kansas State University show that they also can cause harm. Researchers in K-State's Cardiorespiratory Exercise Laboratory have been studying how to improve oxygen delivery to the skeletal muscle during physical activity by...

Scientists Discover Clues To What Makes Human Muscle Age

A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself. The findings will be reported in the Sept. 30 issue of the journal EMBO Molecular Medicine, a peer-reviewed, scientific publicationof the European Molecular Biology Organization. "Our study shows that the ability of old human muscle to..."

Herbal Medicines Can Be Lethal, Pathologist Warns

A University of Adelaide forensic pathologist has sounded a worldwide warning of the potential lethal dangers of herbal medicines if taken in large quantities, injected, or combined with prescription drugs. "There's a false perception that herbal remedies are safer than manufactured medicines, when in fact many contain potentially lethal concentrations of arsenic, mercury and lead," Professor Byard says.

Reduced Muscle Strength Associated With Risk For Alzheimer’s

Individuals with weaker muscles appear to have a higher risk for Alzheimer's disease and declines in cognitive function over time, according to a report in the November issue of Archives of Neurology, one of the JAMA/Archives journals.

Tai Chi Improves Arterial Compliance and Muscle Strength in Older Subjects

Older subjects who regularly practise Tai Chi were found to have better arterial compliance and greater muscle strength than non-practitioners. Exercise which can achieve both cardiovascular function and muscle strength "would be a preferred mode of training for older persons," say investigators.

Study Suggests Popular Muscle-Boosting Supplement Does Not Increase Blood Flow

A Baylor University study has found that a popular nutritional supplement that is marketed to lead to greater muscle strength through increasing blood flow...
