Genetic background associated with physically active lifestyle

In a large international study, researchers at Uppsala University have identified DNA regions that are associated with physical activity or leisure screen time. The findings, published in Nature Genetics, confirm that physical ...

How it works: The protein that stimulates muscle growth

In the gym, you are not just pumping iron, you are oxygenating muscle cells which keeps those muscles healthy, strong and growing—a process called hypertrophy, or an increase in muscle mass due to an increase in muscle ...

Rapamycin may suppress muscle aging and prevent sarcopenia

With life expectancy increasing, age-related diseases are also on the rise, including sarcopenia, the loss of muscle mass due to aging. Researchers from the University of Basel's Biozentrum have demonstrated that a well-known ...

Muscles support a strong immune system

In the fight against cancer or chronic infections, the immune system must be active over long periods of time. However, in the long run, the immune defense system often becomes exhausted. Scientists at the German Cancer Research ...

A mechanism capable of preserving muscle mass

Skeletal muscle is the most abundant tissue of the human body (about 40%) and it plays essential role in locomotion and vital functions (heart rate, breathing). During aging, in a large majority of individuals a loss of muscle ...

Exercise-induced hormone irisin triggers bone remodeling in mice

Exercise has been touted to build bone mass, but exactly how it actually accomplishes this is a matter of debate. Now, researchers show that an exercise-induced hormone activates cells that are critical for bone remodeling ...

Gene could play role in body's muscle mass

Scientists have identified a gene they think could play a role in determining a person's muscle mass - which is linked to a number of health factors, including how long someone lives.
