简要总结
The main objective of this study is to obtain data for the integrated analysis of morphological, functional and biomechanical parameters pertaining to lower limb arteries in various categories of elite athletes (without cardiovascular risk and practicing high- or low-impact aerobic activities which preferentially implicate lower limb activity) as compared to (each other and to) sedentary controls.
详细描述
Secondary objectives of this study are:
A. Determine the presence and extent of intima-media calcifications in athletes B. Determine the relationship between these calcifications and the level, length and intensity of sports activity.
C. Determine the relationship between these properties and calcification of the arterial wall D. Analyze the relationship between the type of sports activity and properties of the arterial wall.
E. Examine the relationship between the properties of the arterial wall and peripheral perfusion pressures.
F. Examine the relationship between the properties of the arterial wall, changes in afterload, morphology and systolic heart function.
