If you’re an older adult, a 30 min workout may not be as effective, even at the cellular level, as it was when you were younger. According to a new study, age may play a significant role in a cell’s ability to respond to that activity. In the study, a group of men 18 to 30 yo were tested against a group of older men 55 years and older...

A Uni of Guelph professor has uncovered the “secret” to staying strong as we age – superb fitness. Geoff Power found elderly people who were elite athletes in their youth or later in life – and who still compete as masters athletes – have much healthier muscles at the cellular level compared to those of non-athletes.
The study compared world-class track and field athletes in their 80s with people of the same age who are living independently. There have been few such studies of aging and muscle weakening in masters athletes in this age group...
Read MoreUni of Georgia scientists have shown a hormone instrumental in the aging process is under genetic control, introducing a new pathway by which genetics regulates aging and disease. Previous studies have found that blood levels of this hormone, growth differentiation factor 11, decrease over time. Restoration of GDF11 reverses cardiovascular aging in old mice and leads to muscle and brain rejuvenation, a discovery that was listed as one of the top 10 breakthroughs in science in 2014.
Scientists in the UGA College of Family and Consumer Sciences have now discovered that levels of this hormone are determined by genetics, representing ano...
This brings scientists a step closer to developing therapies to counteract the aging of cells, by targeting mitochondria. In a study, published today in the EMBO Journal and led by Dr João Passos at Newcastle University, they found that when mitochondria were eliminated from aging cells they became much more similar to younger cells. As we grow old, cells in our bodies accumulate different types of damage and have increased inflammation, factors which are thought to contribute to the aging process.
The team carried out a series of genetic experiments involving human cells grown in the laboratory and succeeded in eliminating the majority, if not all, the mitochondria from aging cells...
