| Strength of quality is fitness training in development levels is an important symbol of all physical quality of the explosive is to speed, force, is an important quality in many sports, especially the power of the project, explosive force as a basic quality of the runner and explosive training has been training is strength of a hot issue.Jump practice is the backbone of pressure to increase the rate of action, young sprinter the limb of the explosive role very effective, prancing into dancing a practice leg exercises and legs to jump practice leg exercises. the jumping and legs about the characteristics of different exercises, hip, knee, her limb, knuckles and the impact of different muscles, it is in the development of the lower limbs explosive are different.This article summarizes the legs to jump practice of training means one leg and one of the legs to jump practice of training means and the legs in contrast, experiments. The two types of training means for the development of combination of explosive young sprinter limb, the young sprinter limb explosive training provide advice and information. after three months training, that the results:1 Experimental group and the targets of explosive and the former is a significant increase in one leg. show jumping experimental group combination of training means and legs about the combination of training means young sprinter limb of the explosive is notable results.2 Experimental group and by the fruit of the comparative analysis found:experimental group speed indicator, explosive force indicators improved the rate of one leg. the price of running jump practice to start up the stage and the ability and explosive to be superior to the limb of the legs. various jump practice 3 Test experimental group after the 100 meters and the special achievements of the 100 metres of special grades no gender differences. on the increase the workout:are many factors leading to a result, the lower limbs explosive increase results of the major factors, but supper limb and body of explosive and endurance to improve the rate of increase is also very important role.4 Exercise of its structure and of the technical characteristics similar to a higher level and quality of the more benign from, the better. hop, stepped out one leg, jumping, the muscles of the exercise of the working methods and sprinting skills are very close to the development of the runner special qualities of effective means. |
