The older we get the more we have to implement a habit of exercising to avoid major issues from inactivity. “Women with poor physical fitness display significantly higher platelet activation than women with average to very good fitness. That is the major finding of a study of 62 young women, conducted by the research groups of Ivo Volf (MedUni Vienna Institute for Physiology) and Rochus Pokan (University of Vienna Institute for Sports Sciences) and sponsored by the Austrian Heart Foundation. Platelet (thrombocyte) activation can lead to the formation of potentially life-threatening blood clots. These blood clots can block blood vessels (thrombosis) and cut off the blood supply to organs.
The findings from this study have been published in the leading international journal Medicine & Science in Sports & Exercise. At the same time, however, the researchers were able to show that this platelet function normalized very quickly as a result of increased fitness — this was achieved by endurance training (running for a maximum of 40 minutes) just three times a week over the two-month period.
Cardiovascular diseases and their acute forms of heart attack and stroke are the commonest causes of death throughout the world. These diseases develop over several decades and are favoured by several risk factors that have a negative impact upon the function of various target cells. Activation of blood platelets can cause clumping of these cells and hence the formation of a thrombus (clot), which impedes blood flow. Activated platelets are also involved in inflammatory processes. For this reason, excessive platelet activation can also encourage inflammatory processes, which can bring about a rapid deterioration of the clinical picture in patients with cardiovascular diseases”
