Résumé
Case 1: A woman in her 70s was carried into emergency department of our hospital. Apparently she had dyspnea. Acute pulmonary heart was suspected. Electrocardiography S I Q III T III-pattern. The patient was diagnosed with popliteal vein vascular aneurysm by ultrasonography. Case 2: A man in his 60s, was referred to our hospital for treatment of lower extremity swelling and pain. Like Case 1, the male patient was suspected of having deep vein thrombosis and femoral artery aneurysms by ultrasound inspection and also diagnosed with pulmonary thromboembolism based on CT findings. We were able to rescue these two patients by rapid medical cooperation. Ultrasonography was particularly useful for diagnosis and morphological evaluation of blood vessels.
Résumé
Well-trained young swimmers seem to have different physical characteristics as compared with non-athletes of the same age group. The purpose of this study was to determine physical characteristics of well-trained young competitive swimmers from a standpoint of differences in training, sex, and growth and development. A total of 47 boy and girl swimmers and 124 untrained boys and girls were selected as subjects.<BR>All swimmers began to swim regularly in an elementary school age and continued hard swimming training for at least 2 years. A battery of 53 parameters representing each physical domain such as physique, muscular strength, flexibility, neuromuscular function, cardio-respiratory function, were selected to examine subject's physical characteristics. The following results were found : boy swimmers have less body fat, superior physique, mascular strength, flexibility, agility, and also superior cardio-respiratory function as compared with untrained boys. Also girl swimmers have almost the same physical characteristics except for physique and general static strength. Boy swimmers possess larger stature and bone width, and superior muscular strength and cardio-respiratory function as compared with girl swimmers. A similar sex difference is found in non-athletes. High school swimmers have more solid body mass, and superior dynamic and static strength, relating to an achievement of swimming speed, than junior high school swimmers.
