Effects of shoe collar height and sole hardness on balance in older women
Effects of sole hardness and shoe collar height have been studies as they relate to balance in older women and finding show balance is better with high collars with sole hardness not related. The subjects, of whom there were 42, were aged 60-92. The view that stability around the heel and ankle is a desirable feature for footwear in the age group studied is widely held, but no studies had evaluated it. In a related study ability to balance in cowboy boots and tennis shoes was evaluated in young women. Performance was poorer in the boots.

Myocardial GLUT-4 glucose transporter protein levels of rats decline with advancing age
GLUT-4 protein levels in the left ventricle of rat hearts decreased significantly with age, a relationship which has already been shown for adipose tissue and skeletal muscle. GLUT-4 levels start to decline early in life and continue to decline during adulthood. As rats aged from 3.5 months to 13 months, GLUT-4 levels per mg of protein fell 15%; by the age of 25 months the level fell an additional 12%. Total amount of protein remained stable.
