The Kinematics Research Of College Volleyball Athelets’ Spike Technique And Sports Injury In Gansu Province

Sports injury refers to a variety of injuries that occur in sport, especially thesports-related injury which occurs in technical movements. because volleyballmovement has intensely and adversarial attack, it`s defense conversion, it`s movementcharacteristics, it`s practice of teaching, training and competition, thus lead to avariety of sports injuries, affecting the movement of success. In this study, to beadopted from Gansu Province College Students in volleyball spiker spike actionsports biomechanical methods and high-speed image resolution, trying to reveal thecommon problems that existed in the College Students in the technology, try to makea breakthrough in technical analysis, combined with the coach`s special physicalcircumstances of daily training arrangements, try to give members and athletes acomprehensive evaluation, to explore the relationship between the volleyball spiker`sspike technology and their sports injuries, to address these issues for a furtherimprovement, propose appropriate countermeasures for a further improvevent in theirmovement conditions, to improve the teaching and training ways, to go further toenrich and improve the basic volleyball thoery research for the Universities in GansuProvince, especially provide the reference and practical guiding significance forVolleyball movement theory in sports training. The results are as follows:1、Gansu Province University Volleyball athlete’s injury is caused often due tonon-standard technical movements,chronic fatigue is the typical characteristic, the siteof injury, which mainly occurs in the shoulder, elbow, waist, knee, ankle and otherbody parts.2、Excessive shoulder outreach is the largest force for the main direct cause ofshoulder injury. Affect a number of motion parameters in the abduction angle of theshoulder hitting, arm injury has a certain impact for shoulder movement, but themaximum force of lower limb force order, and pull the arm too late is the main reasonfor sports injuries.3、When in air hitting stages, elbow extension is the main direct cause of theelbow injury caused. Kinematic parameters in a number of hitting the maximumextension angle of the instant elbow, shoulder braking too late is the maximum extension angle of the impact of elbow and result in sports injuries to a technical error,which belongs to the primary technical error.4、Excessive draft arm and maximum trunk torsion are the main direct factorscausing athletes with low back spine injury, which belongs to the primary technicalerrors, while the middle abdomen strength of trunk had reversed the main physicalfactors.
