Investigation And Research On The Training Method Of Torso Strength Of Elite Throwing Athletes In Heilongjiang Province

Throwing project is a basis to force, speed is the core of the sport. Force is generated by muscle contraction, throwers in order to achieve excellent athletic performance, not only to master the operation of technology projects, but also has good power quality.Trunk strength exists in all sports, all sports movements are at the core of the trunk muscles kinematic chain, strong trunk muscles for movement in the body posture, movement technology plays a role in the stability and support. The trunk is the core of all movements, the human body strength from the torso, the dominant and integrated into limbs. Throwing project technical action involves multiple planes inside the body in the trunk muscles play an integral function in the body to form a power transfer chain is completed campaign mission. Therefore, the throwing athlete torso strength training research, contribute to the comprehensive development of athletes’ athletic ability, improve athletic performance.This paper uses the literature, expert interviews, questionnaires, on-site observation, testing, mathematical statistics and logical analysis and other research methods, Heilongjiang Province Elite Throwers torso strength training methods of research, through research Heilongjiang Province Elite Throwers Status torso strength training, strength training explore trunk characteristics, constraints analysis, and the corresponding improvement strategies. We want to provide a reference for future Throwers torso strength training development.Through this study, the conclusion drawn look:1. Trunk strength Heilongjiang Province has 44 kinds of training methods, the development of trunk strength with good results, in which the trunk stabilizing force in nine kinds of training methods; 8 kinds of trunk flexion strength training methods; trunk strength back seven kinds of training methods; trunk flexion strength 5 kinds of training methods; 13 kinds of trunk rotation strength training methods; trunk surrounded by two kinds of strength training methods.2. Trunk strength training are characterized by: overall, the special nature. The trunk flexion strength, trunk extension strength after, the main development trunk flexion strength locus strength of large muscle groups; the trunk stabilizing force, torso rotation strength, trunk strength surround the track, developing a small muscle strength, emphasizing the torso overall performance.3. The main factors restricting the development of trunk strength training: coaches, athletes torso strength training is deficient in basic principles of cognitive theory; the implementation process, the magnitude of practice means lower quality muscle strength development is not balanced, do not pay attention to breathing training, strength inadequate training equipment.4. Improvement Strategy of Heilongjiang Province Outstanding Athletes main trunk Strength Training: There improve coaches, athletes cognitive level, reasonable arrangements for training torso strength training content, rich torso strength training method to increase pre-training torso muscle activation link deal good relationship trunk load and restore power, reasonable arrangements for the training sequence, reasonable arrangements for diet nutrition supply, purchase machinery and equipment based on actual demand.
