查询词典 beam-focusing

In the procedure of gymnastics athletes' U.C., the functions of the conditional ability performing now are more and more important in the competitive abilities of the floor exercises; besides the sport technique and conditional ability, one should pay attention to the figure in the pommel horse; the importance of the conditional ability is far above the sport technique , and the requirements of the figure are also high in the rings; the characters of competitive abilities of the vaulting horse are similar to those of the floor exercise, in which conditional ability plays a very important role; the requirements of the sport technique in the parallel bars are above those of the conditional ability; the requires of sport technique in the horizontal bar are strikely above those of other individual events, and the psychological ability is above the conditional ability; uneven bars contains much techniques, which means, sport technique is above the conditional ability; balance beam also contains much techniques and requires the least in the conditional ability in women's events, but this individual event demands psychological ability badly. Therefore one should emphasize on the cultivation the psychological ability when U.C. is applied to the balance beam.
