The formation of rumba player's body weight and barycenter, and the relationship between the barycenter and shifting are the key technology for rumba technique. There has been some progress on the study of the weight shift technology in transport step forward and backward about rumba, but there are still some practical problems in application. In this paper, we conduct a study on rumba player's barycenter Shifting technique with a method of human motion mechanics. We analysis the position changes when the barycenter shifts and the physical stability in the process of barycenter shifting. The study shows that the grasp of barycenter shifting has an absolute effect on rumba players and helps maintain dancemovements fluent and coherent. By analyzing and applying this technology, players canmake new breakthrough in training and stand out in the competition, thus has certain practical significance. © 2013 Trade Science Inc. - INDIA.

To study the effects of basic fibroblast growth factor (bFGF)-coated magnetic nanoparticles on the recovery in rat skeletal muscles after acute contusion, recombinant bFGF-coated magnetic nanoparticles were produced by immunochemical coupling techniques. The acute skeletal muscle contusion was produced by heavy objects dropping devices. Subcutaneous injection or blank control were performed respectively with each group and targeted and focused at the injured site with the guidance of external magnetic fields. The muscles were sampled at day 2, 10, 17, 24 and 30 respectively after contusion, and then the muscle contractive strength and relaxation were measured and calculated. SOD activity and MDA content in rat serum was determinated. Magnetically nanocrystallized bFGF could significantly increase the SOD activity at day 2-10 after injury. From day 2 after contusion, magnetically nanocrystallized bFGF could restore the muscle relaxation back close to the normal level. Compared with the direct injection bFGF group, BFGF-coated group more significantly increased the muscle contractive strength at day 17 (P <0.05). BFGF-coated group was significantly different from other four groups in the MDA content at day 2-10 after contusion (P <0.05). Magnetically nanocrystallized bFGF could significantly enhance the contractive strength, scavenge free radical after blunt injury, restore the muscle relaxation and improve more effectively the healing of injured muscles in rat acute skeletal muscle contusion.
