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.
