| Outline of Final Research Achievements |
We aimed to quantify factors influencing thrombus formation at the time of sports activities, and compared different exercise intensities, exercise times and the extent of dehydration and thrombosis. The relationship with the formation-related factor (VWF, ADAMTS 13) was also examined. As a result, thrombus formation-related factors (VWF/ADAMTS 13) indicating the tendency of thrombosis during exercise were affected by exercise intensity rather than exercise time. In addition, it was recognized that there was an "exercise intensity threshold" at which the thrombosis tendency increased significantly at about 55%VO2max. Finally, considering the relationship between the dehydration rate and thrombus formation-related factors, the difference in the dehydration rate due to the difference in ambient temperature did not affect the change in thrombus formation-related factors. These results suggest that the thrombotic tendency seen during exercise is due to exercise intensity.
