Abstract
Physical efforts were reported increase unconstantly platelet count as well as mean platelet volume (MPV). However these findings, dependent on some mechanisms occuring in the exercise, i.e. hemoconcentration, change of platelet splenic pooling, increased production of platelets. Till now it is not well clarified if the changes of platelet indexes may represent a persistent pattern in well trained athletes. Thus in the present research PC, MPV, and platelet dimensional width (PDW) were compared between a group of long distance runners, during basal training, and a group of sedentary healthy subjects. Thirty-four runners, ten females and twenty-four males (aged 20-45 years,covering 50 to 160 km/week), as well as thirty-four healthyuntrained non-smoking volunteers (aged 18-46 years) of both sexes were admitted to the study: The mean PCs as well as the MPV from male and female groups of runners did not differ from the respective groups of controls. PDW was significantly different between male runners and control, as well as between female runners and controls. PC, MPV and PDW did not correlate with the runners' age and the kilometers weekly covered.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
