Abstract

^{Volleyball as a skill leading type of separate net antagonistic project, a number of technologies need athletes to jump to complete, which undoubtedly brings a large load to the body's joints, and in the state of fatigue, the athlete's emergency stop, rapid change to move will greatly cause joint damage Good joint proprioception function and balance ability play a crucial role in maintaining the stability of body posture, which can effectively reduce the acute injury caused by the spatial position change of body posture in the process of exercise. However, in the current training, the coaches focus on how to improve the offensive and defensive ability, and do not pay enough attention to the training of preventing joint injury and enhancing joint stability. If there is injury, the training effect and competitive ability of athletes will be greatly affected.}

^{The purpose of this study is based on the volleyball students training in routine training to increase the stability, will explore the unsteady training for volleyball the balance ability of students and ankle proprioception function, so as to enhance volleyball students in the process of movement's ability to maintain a stable posture, reduce the risk of injury This paper USES documentary expert interview method Questionnaire survey method, mathematical statistics and experimental method to Beijing sports university education college class of 2019 men's volleyball special class 16 players as experimental object, randomly divided into experimental group and the control group, each group of eight people, in the experimental group for 8 weeks unsteady control group for 8 weeks the normal balance of training, training before and after the experiment respectively on two groups of subjects of ankle proprioception Static balance ability and dynamic balance ability are tested and analyzed, and the following conclusions are drawn:}

• ^{Unsteady training for the location of the plantar flexion of ankle joint varus outer movement has significant positive influence, has a positive effect on dorsiflexion movement but not significantly, with the raised under the imbalance of the muscle group and the activation degree of the nervous system, under the imbalance body forward actively, leading ankle dorsiflexion movement to smaller activation degree of the tibialis anterior muscle and muscle fibers to raise fewer.}
• ^{Unsteady training for volleyball students ankle proprioception function improvement of have obvious effect, after standing on one foot Swan to balance this kind of static movement, unstable plane makes body shaking, proprioceptive sensitivity joints and nervous system control of the muscles are enhanced, prompting of volleyball rapid change in the joints and muscles to move The perception of spatial position changes in the form of take-off and landing is enhanced, and the risk of injury caused by spatial position changes is reduced.}
• ^{The unstable training of volleyball students' static balance ability has been significantly improved, in the unstable plane to complete the static movement of the center of gravity is not stable to stimulate the deep more core muscle group to participate in the work, enhance the core stability of the trunk, to ensure the stability of the body posture to lay a good foundation.}
• ^{According to the experimental results, it can be found that the dynamic balance ability of volleyball students has been significantly improved, and they can complete lunge and knee lifting with one foot and four-way ground in unstable state The dynamic exercises such as standing on one foot bent over the little motor neuron was first raised, the small muscles around the ankle was drastically, ankle proprioception function of ascension can effectively improve proprioception system's ability to control body movement, the muscle coordination in the movement to maintain body balance in volleyball has a crucial impact on fast attack and defense conversion.}
