Aortic Dissection Type A in Alpine Skiers
PATIENTS AND METHODS 140 patients with aortic dissection type A were admitted for cardiac surgery. Seventy-seven patients experienced their dissection in the winter season (from November to April). We analyzed cases of ascending aortic dissection associated with alpine skiing. RESULTS In 17 patients we found skiing-related aortic dissections. Skiers were taller (180 (172-200) cm versus 175 (1...
متن کاملBiomechanical analysis of double poling in elite cross-country skiers.
PURPOSE To further the understanding of double poling (DP) through biomechanical analysis of upper and lower body movements during DP in cross-country (XC) skiing at racing speed. METHODS Eleven elite XC skiers performed DP at 85% of their maximal DP velocity (V85%) during roller skiing at 1 degrees inclination on a treadmill. Pole and plantar ground reaction forces, joint angles (elbow, hip,...
متن کاملThermoregulatory Responses in Cross-country Skiers a Field Study
Outdoors activities, such as cross-country skiing, may expose the human body to severe thermal stress during training and competitive events in the winter season. Cooling affects all aspects of muscular performance (1), and cold has a profound effect on the functional properties of skeletal muscle. When exercise intensity is high enough to maintain core temperature, but skin cooling is still pr...
متن کاملDetection of autologous blood transfusions in cross-country skiers.
Transfusion of autologous blood (blood doping) has been used by athletes to improve performance in sports events. This practice has been banned by the International Ski Federation (FIS) and the International Olympic Committee (IOC). So far, no reliable method for detection of blood doping has been available. In the present study, a group of six elite cross-country skiers, who were phlebotomized...
متن کاملPhysiological differences between sprint- and distance-specialized cross-country skiers.
PURPOSE Sprint- (≤1.8 km) and distance-skiing (≥15 km) performance rely heavily on aerobic capacity. However, in sprint skiing, due to the ~20% higher speed, anaerobic capacity contributes significantly. This study aimed to identify the possible anthropometric and physiological differences between elite male sprint and distance skiers. METHODS Six sprint and 7 distance international-level cro...
