Abstract

7 swimmers and 20 students majoring in physical education (call students for shorts) aged from 18 to 21 years were participated in this test. Their height,weight and skinfold were measured, and their performance concerning with fingers-behind-back-touch (Call f.b.b.t. for short) right and left flexibility, backward flexibility and forward flexibility were tested too. Correlationsof these data were investigated. The results were as follows: 1) The correlation between f.b.b.t. left and right, backward flexibility, and upper arm and back skinfold thickness were shown in swimmer and students. 2) The correlation between backward and forward flexibility, and Rohlers Index and upper arm, back skinfold thickness were shown in swimmers only. 3) In students, flexibility in these test items tended to be increased. In swimmers, those were a little or did not change. 4) In students, f.b. b.t. right, f.b.b.t. left and forward flexibility tended to be increased after exercise. In swimmers, those tended to be reduced after exercise. In all of the subjects, backward flexibility tended to be reduced after exercise. 5) In swimmers, thickness of upper arm and back skinfold were thicker than those of students. In Rohlers Index, a same tendency was shown too. 6) In difference between f.b.b.t. right and left flexibility, swimmers total war largely compared with that of students. Verf.-Referat
