Abstract:
The morphological changes of the humerus and femur were examined in 52 sports- men (30 weight-lifters-static type of movement and 22 runners—dynamic type of move- ment).The results were as follows: 1.In the humerus of the weight-lifters the thickness of the wall of bone was very much increased as compared with that of the runners and,as a result,the transverse diameter of the shaft enlarged and the cavity diminished. 2.In the femur,however,no such changes were observed in both types of exercise. On the contrary,there is some indication that the femur of the runners increased in longitudinal direction. 3.In the weight-lifters,the thickness of the wall of the bone was not only shown in the shaft,but also in the metaphyses where it ended as a sickle in the longitudinal section.On the other hand,that of the runners gradually pointed out. 4.The bony prominences of the humerus of the weight-lifters were very much marked and its internal bony lamellae were clearly visible.
