Therefore, by experimenting on the velocity training of the upper limbs moving straight forward under the condition of different fixe d working patterns, have made a study of the different effects from the motion velocity training. The results indicate that the exercise of combination of far and near fixations is more effective than the pure exercise of either far or near fixation in increasing motion velocity. The experiment has meanwhile revealed some s ignificance of the exercise of combinations in the course of continuous training to increase "middle position" velocity. Key words: motion velocity; biomechanic; fixed working pat tern |
