The purpose of this study was to investigate and compare body composition of deaf and hearing persion. For this purpose, 16 trained deaf, 11 untrained deaf, 20 hearining person(control) were selected. The results were as followings. 1. The body fat weight showed significant difference(p<.05) and the predominant order of the mean value of body fat weight was control(7.57±2.69㎏), untrained deaf(6.45±1.83㎏), trained deaf(5.44±1.49㎏). The body fat percent showed significant difference(p<.05) and the predominant order of the mean value of body fat percent was control(11.55±3.87%), untrained deaf(9.60±2.34%), trained deaf(8.61±2.13%). 2. The lean body weight showed no significance and the predominant order of the mean value of lean body weight was trained deaf(58.38±5.52㎏), control(57.57±7.21㎏), untrained deaf(57.03±4.45㎏). The lean body percent showed significant difference(p<.05) and the predominant order of the mean value of lean body percent was trained deaf(91.40±2.14%), untrained deaf(90.40±2.34%), control(88.46±3.88%). 3. The total body water weight showed no significance and the predominant order of the mean value of lean body weight was trained deaf(41.98±3.60㎏), control(41.01±4.20㎏), untrained deaf(41.00±2.42㎏). The total body water percent showed significant difference(p<.05) and the predominant order of the mean value of lean body percent was trained deaf(65.81±2.32%), untrained deaf(65.07±2.00%), control(62.53±4.67%). 4. The body mass index showed no significance and the predominant order of the mean value of body mass index was untrained deaf(21.64±1.22), control(21.42±2.12), trained deaf(21.09±1.62).
