Effect Of Different Exercise Forms On Proprioception Of Knee And Ankle Joints In Young Athletes

Objectives: In sports, ankle and knee injuries are the most common occurrence of sports injury. In acute sports injury, the incidence of ankle and knee injuries up to 33%-42%. Therefore, recurring ankle instability of knee joint and the functional become is an evidence of ankle knee injuries. However, factors that influence the ankle knee functional instability is mainly to reduce joint mobility, reduce eversion of the muscle and joint proprioception. Therefore, some scholars pointed out that functional ankle instability because of unstable symptoms resulting from loss of mechanical. In search of literature, mostly in the medical treatment as the main research direction, and to explore the knee ankle proprioception in different sports less the role of related literature. Based on this study taekwondo, walking race and table tennis three sports athletes ankle proprioception accuracy measurement, discusses different sports on the athletes knee ankle proprioception whether to have impact, the impact is there a difference, and with less exercise at ordinary times the comparison analysis of ordinary people. In order to improve the selection of athletes proprioception and provide theoretical basis to prevent sports injury.Methods: Experimental group for 19 to 24 men between the age of 60 people, including practice life of more than three years of tae kwon do, walking and three table tennis sports of male athletes each 15 people, and 15 boys from Shandong sports institute, and no regular exercise at ordinary times for the control group. Subjects require no ankle injury within a year, all the participants before the test tested to explain in detail to ensure the correct understanding of the test, and sign the test agreement. Feeling ontology through testing instrument to test of the subjects, the knee ankle proprioception(motion perception), discusses the similarities and differences between groups.Results:a) The study found that groups of subjects to side with the advantages there is no significant difference between lateral knee ankle proprioception.b) Taekwondo group, the walking group and table tennis group of motion perception threshold value is less than the control group with significant difference.c) Walking group in the ankle and knee flexion and extension direction of motion perception thresholds are much smaller than taekwondo group, but curl, flip and direction of motion perception threshold group is significantly higher than taekwondo.d) Table tennis group motion perception threshold than taekwondo group and table tennis.Conclusions:a) The ability of the body of the knee ankle joint is superior to those of the person who exercises and is engaged in regular exercise.b) Different sports affect athlete knee ankle proprioception are different.c) Walking race group in the ankle and knee flexion and extension direction of ontology taekwondo group is obviously better than the feeling ability, however, turn the proprioception and eversion direction ability significantly worse in taekwondo group.d) Proprioception of knee and ankle joint table tennis group difference in Taekwondo group and walking group.
