| La-la-la operating as a sports collection of music, dance, gymnastics, entertainment and fitness at an organic whole and very popular with young people. With flexibility and balance, leapfrog and swivel is of dance. Practice proved, dance hold players spend a lot of time in daily training of class action of practice, in a practice game or performance, or to little effect. Based on this, the author using research methods of literature and experiments, considering from an operational level, and combined with the author for many years to participate in the dance exercise experience, with hunan normal university sports institute dancing la-la-la operating team of 12 players as the research object, the core strength training and sports dance, the plane of action phase1.Before and after the experiment, subjects in the experimental group and the control group there were significant differences in level and complete the whiplash turn 180 degrees and 360 degrees rotation time in addition, through the 8 week core strength training intervention, the experimental group subjects in turn and finish the whiplash turn, in the ready position and start posture, swivel 180 degrees and 360 degrees angle with the trunk before the experimental study compared significant difference, while the control group before and after the experiment does not have what change; 2. Control group and experimental group subjects have a certain improvement in the complete flat turn body each angle, especially in the experimental group and the effect of left and right knee the left hip angle is especially obvious, at the same time, through the core strength training intervention, the fluctuation range of more subjects in the experimental group of swinging leg hip angle to complete the high quality of the whiplash movement; 3. Before and after the experiment, the experimental group and the control group Subjects completed flat spin action, the experimental group through the core strength training intervention and improve the joints of the body of the speed effect is more obvious; 4. Through the intervention of the core strength training, the experimental group subjects were in complete whiplash turn action, in the speed of swinging leg off, swivel 0-180 degrees and swivel 180-360 degree three stages of promotion effect is obviously better than that of the control group. In addition, the experimental group subjects were in control of the strength of support legs, the body center of gravity, whiplash turn motion stability and upper limb movement time and significantly better than the control group. |
