Overweight and obese adults are advised to exercise to improve their health, but more than 50 percent do not do so. New research to be presented at the 14th International Conference on Endothelin: Physiology, Pathophysiology and Therapeutics suggests that taking vitamin C supplements daily can have similar cardiovascular benefits as regular exercise in these adults.

Potential mechanisms contributing to low bone mass and increased fracture susceptibility in diabetes mellitus.

“Clinical trials have revealed a startling elevation in fracture risk in diabetic patients,” says Liyun Wang, associate professor of mechanical engineering at the University of Delaware. “Bone fractures can be life threatening – nearly one in six hip fracture patients dies within a year of injury.” As physical exercise is proven to improve bone properties and reduce fracture risk in non-diabetic people, Wang’s group decided to test its efficacy in Type 1 diabetes.

Osteocytes are critical to maintenance of the tissue quality and mechanical integrity of bone...

1st glimpse of potential effects of Exercise on the brains and cognitive abilities of the ‘oldest old.’ In the summer of 2012, Olga Kotelko, a 93-year-old Canadian track-and-field athlete with more than 30 world records in her age group, submitted to an in-depth analysis of her brain.

A retired teacher and mother of two, Kotelko started her athletic career late in life: slow-pitch softball at age 65, and at 77 switched to track-and-field events...

The higher intelligence score, the better physical performance, the study reveals. We would all like to stay independent, as we get older. In order to succeed, we need to be in good physical shape. This includes being able to cope with everyday physical activities such as getting dressed and carrying our own shopping. Scientists employ a number of tests, e.g. handgrip strength, balance and chair-rise, when measuring physical performance.

Researchers at the Center for Healthy Aging and the Department of Public Health at the University of Copenhagen have studied the association between male intelligence in early adulthood and their subsequent physical performance, aged 48-56. The study comprised 2,848 Danish males born in 1953 and in 1959-61.

“Our study clearly shows that the higher intelli...
