The relationship of left ventricular to femoral artery structure in male XXXX .

@entity1 @entity3795 @entity2587
PURPOSE: In @entity1 , cardiac morphological adaptations to athletic training have been exhaustively described, while the existence of morphologic (adaptive) changes in the peripheral vessels are less well known. Therefore, the scope of the present study was 1) to assess the existence of morphologic changes in the peripheral vessels, such as the common femoral artery ( @entity3795 ), in @entity2587 engaged in different types of sports; and 2) to assess the relationship existing between the cardiac and @entity3795 changes in highly endurance- ( N = 16) and strength-trained @entity2587 ( N = 15), and in sedentary controls ( N = 20). METHODS: The cross-sectional diameters of the left ventricular (LV) posterior wall and cavity and @entity3795 diameter and intima-media thickness were determined by M-mode echocardiography and ultrasound, respectively. RESULTS: @entity3795 intima-media thickness in the endurance-trained (0.33 +/- 0.03 mm.m(-2) ) was similar to the strength-trained @entity2587 (0.34 +/- 0.05 mm.m(-2) ) and both greater (P < 0.01) compared with the controls (0.27 +/- 0.03 mm.m(-2) ). @entity3795 diameter in endurance-trained @entity2587 (5.6 +/- 0.6 mm.m(-2) ) was highest among groups (strength-trained @entity2587 4.2 +/- 0.4 mm.m(-2), controls 4.2 +/- 0.5 mm.m(-2) ). Thus, the relative @entity3795 wall thickness (2.intima-media thickness/ @entity3795 diameter) was significantly higher (P < 0.01) in the strength-trained (0.16 +/- 0.02) than in the endurance-trained @entity2587 (0.13 +/- 0.02) and the controls (0.13 +/- 0.02), respectively. The relative LV posterior wall thickness (2.LV posterior wall thickness/LV diameter) was not significantly different among the groups. LV posterior wall thickness was significantly related to @entity3795 intima-media thickness (r = 0.31, P < 0.05) and LV diameter to @entity3795 diameter (r = 0.55, P < 0.01). CONCLUSIONS: The study shows a physiological relationship between the LV and @entity3795 wall and cavity dimensions in endurance-trained @entity2587 and controls, respectively. The greater relative wall thickness of the strength-trained @entity2587 may be related to different influencing factors, e.g., increased blood pressure.
