Research On The Relationship Between Sports Injury And Mental Fatigue Of CUBA Athletes

Objective:from the perspective of sports injury risk cognitive theory explain college basketball sports injury and the correlation between mental fatigue, at the same time the sport injuries of determination of risk cognition of mental fatigue prediction, based on the cognitive theory of sports injury risk, assuming that sports injury risk cognition of mental fatigue has remarkable positive forecast function, and through the transverse and longitudinal study to test the research hypothesis was established, in order to prevent CUBA college basketball athletes psychological fatigue caused by sports injury resulting in decreased competitive ability to provide important theoretical and practical reference.Methods:for 137 CUBA men's basketball player, test the damage of the movement of athletes, sports injury risk cognitive level, mental fatigue, using the correlation analysis, maximum likelihood method by using covariance structure model of sports injury and psychological fatigue transverse analyses; To 24 CUBA men's basketball athletes as experimental object, the in the interval of 2 weeks before and after the game, sports injury risk cognitive and psychological fatigue test athletes, by using linear regression analysis on sports injury and psychological fatigue for longitudinal analysis.Results:(1) the CUBA basketball athlete's sports injury, tops the list, along with the ascension movement level sports injury incidence reduced gradually; Knee, ankle, wrist, elbow is still high rates of athlete's sports injury parts and in the majority with moderate and mild; Back or training after injury occurs mainly in the recovery period, and most of the athletes get shorter recovery time after injury, and even some athletes need to action in a very short time. (2) CUBA college basketball sports injury risk have a significant positive correlation between cognitive and psychological fatigue, sports injury risk cognitive level is higher, the higher the degree of mental fatigue; Building of sports injury to mental fatigue structural equation model shows that the sports injury to athletes' mental fatigue of three dimensions have significant positive prediction function, sports injury to mental fatigue sense of achievement reduce the dimension of the path coefficient was 0.48, a sense of achievement to reduce the variance accounted for 23%; Points from the injury to the psychological fatigue emotion/physical exhaustion dimension path coefficient is 0.51, the emotion/physical exhaustion variance accounted for 26%; Points from the injury to the psychological fatigue coefficient is 0.73, negative evaluation dimensions of path of mental fatigue variance accounted for 41%. The results support the sport injuries of CUBA university basketball transverse prediction of mental fatigue research hypothesis. (3) before the athletes sports injury risk cognition of emotion/physical exhaustion after the game (beta = 0.24, p< 0.01), and a sense of achievement to reduce (beta = 0.27, p< 0.01), negative evaluation (beta = 0.31, p<0.01) significantly positively predict the role; Game athlete sports injury risk cognition can explain emotion/physical exhaustion, a sense of achievement by, sports negative evaluation by 28%,27% and 39% of variance; Athletes sports injury risk cognitive level changes to match the change of emotion/physical exhaustion (beta = 0.22, p< 0.01), the change of achievement reduce (beta = 0.25, p< 0.01), the change of movement, negative evaluation (beta = 0.41, p< 0.01) has a significant positive prediction function, the athlete sports injury risk cognitive level changes can explain the change of emotion/physical exhaustion after the game, a sense of achievement to reduce changes, the change of movement, negative evaluation to reduce 12%,9%,17% of the variance. The results support the sport injuries of CUBA university basketball longitudinal predict mental fatigue research hypothesis. (4) the transverse and longitudinal prediction results show that sport injuries of sports positively predict effect than negative evaluation to cut its forecasts and emotion/physical exhaustion of achievement, for college basketball athletes, sports injury to athletes'mental fatigue more reflect the influence of negative evaluation dimensions in sports. Cross-sectional study, the sports injury of emotion/physical exhaustion forecasting effect is stronger than a sense of achievement to reduce the prediction effect, the longitudinal view, sports injury to a sense of achievement to reduce forecast effect is stronger than emotion/physical exhaustion. Conclusion:CUBA college basketball sports injury is one of the important causes for mental fatigue, sports injury risk cognition of mental fatigue three dimensions have reliable forward prediction effect.Suggestions:(1) the training of students in CUBA basketball player, should control and prevent the occurrence of sports injury athletes, especially for the protection of the knee, ankle, wrist, elbow and prevention, and after the athletes were injured, to fully get treatment and recovery back again, can effectively avoid sports injury happening again. (2) CUBA college basketball players before the game can be adjusted by athletes on sports injury risk cognitive level, can effectively avoid the generation of mental fatigue. (3) the coaches in the process should pay attention to strengthen independent, relationships, and ability of athletes need to meet, make the athlete's basic psychological needs are met, thus can avoid the injury lead to mental fatigue.
