The present study was aimed to investigate the physical ability of javelin throwers among uni-versity students using the magnetic resonance imaging (MRI), and Capacity Test, compared with other throwers.
The anatomical cross-sectional areas (ACCAs) of trunk muscles were determined using MRI. Capacity Test is composed of 30 m sprint, standing triple jump from a double-legged, backward over the head shot, forward over the head shot, sargent jump, snatch, and shoulder flexibility test with a javelin.
Results are as follows:
1. The male javelin throwers (MJT) group showed significant correlation between javelin throw records and ASCAs per body mass of body trunk extensor muscles (r=0.722, p<0.05) .
2. There was significant correlation between the forward over the head shot, and javelin throw in MJT group (r=0.800, p<0.01) . And the same tendency was also seen in female javelin throwers (FJT) group (r=0.735, p=0.055) .
3. The MJT group showed some correlation between javelin throw records and ASCAs per body mass of psoas major muscle (r=0.657, p=0.060) .
By the above-mentioned results, it was considered that the trunk extensors are important for male javelin throwers.

A 44-year-old woman with Marfan's syndrome presented complaining of severe back pain. Angiography revealed annulo aortic ectasia, aortic regurgitation, acute aoric dissection (DeBakey IIIb) and distal aortic arch aneurysm. One month after admission, she underwent cardiopulmonary bypass was established through the femoral artery, the superior and inferior vena cava. The heart was arrested by aortic cross clamping and retrograde cold (20°C) cardioplegia. At first, a modified Bentall's procedure was done in addition to a Carrel patch procedure. After this procedure, the heart was perfused continuously (300ml/min) with warm (37°C) blood until the end of the cardiopulmonary bypass. The heart recovered a sinus rhythm spontaneously. Subsequently, aortic arch replacement and the elephant trunk method was done with the aid of deep hypothermia and circulatory arrest. The patients is well 1 year after the operation. This technique is useful for patients who require prolonged aortic cross clamping time.
