Exercise that exerts a load on bones, such as running, affects bone health more effectively than a load without weight, such as cycling. This conclusion was reached by specialists of Istituto Ortopedico Galeazzi (Italy).
Study author Dr. Giovanni Lombardy says moderate exercise is the best way to strengthen weak bones. Swimming or cycling is much less suitable for this purpose..
Scientists measured the levels of glucagon, leptin and insulin - hormones involved in the regulation of metabolism, as well as the levels of osteocalcin and P1NP (bone formation protein) in 17 professional runners before and after the 65-kilometer mountain race.
The data obtained were compared with the results of the analysis of hormones and bone components of 12 adults who are not marathon runners, but who adhere to low or moderate physical activity.
It turned out that the runners had higher levels of protein associated with bone formation compared with the control group of subjects.
Scientists explained - the results of the study prove that running stimulates bone tissue to secrete glucagon and specific proteins that prevent bones from breaking down. The bones of marathon runners are not idle, experts say, they actively interact with tissues and organs, causing the body's energy reserves to be replenished.
