| Objective:The e Sports industry is developing rapidly in China,especially into the mobile Internet era,and mobile e Sports accelerates the e Sports industry into the industry explosion period.However,the health problems of professional e Sports athletes have also gradually emerged,mainly in the form of musculoskeletal injuries in e Sports athletes,which are further aggravated by the use of smaller screens in mobile e Sports.There is a lack of research on musculoskeletal injuries in e Sports athletes,and research on mobile e Sports athletes is scarce.Therefore,this study aims to investigate the musculoskeletal injuries in mobile professional e Sports athletes,to understand the current status of the injury and to analyze the factors that influence the injury,and to provide a theoretical basis for health promotion,injury intervention and prevention for e Sports athletes.Methods:In this study,a cross-sectional study was conducted with 118 e Sports athletes from one of China’s top mobile MOBA handball professional leagues..Data were collected by questionnaire method on the personal situation,living habits,training environment and habits,and skeletal muscle injuries of e-sports athletes,and evaluated by VAS visual analog scoring method for injury pain and Pittsburgh Sleep Quality Index(PSQI)for sleep quality.The physical fitness of the e Sports athletes was tested by the test method for height,weight,diastolic blood pressure,systolic blood pressure,bone density,grip strength,and reaction time.In the mathematical statistical method,the impairment-related influences were screened by one-way test and chi-square test,and then the impairment factors were modeled and analyzed by binary Logistic regression constructs.Results:1.Basic information:(1)BMI: 27.97% of the e Sports athletes’ BMI was evaluated as lean weight,16.10% as overweight,and 13.56% as obese.(2)PSQI: 31.36% of athletes were evaluated as poor sleep and 10.17% were evaluated as sleep injuries.(3)Myopia: 65.25% of e Sports athletes were myopic.(4)Smoking: The smoking rate of e Sports athletes was 22.03%.(5)Sports habits: Only 27.12% of e Sports athletes have sports habits.(6)Daily training time:83.9% of athletes trained for more than 8 hours a day.(7)Training rest arrangement: 37.29%of the athletes have no fixed rest time during training.2.Musculoskeletal injuries:(1)The overall prevalence of musculoskeletal injuries in mobile e Sports athletes was 78.81%.(2)The prevalence of each part in descending order is:neck(64.41%),lower back(29.66%),fingers(29.66%),shoulder(22.88%),wrist(21.19%),elbow(7.63%).(3)97.46% of the e Sports athletes had 2 or more site injuries.(4)69.57% of the injury pain was mild.(5)The consultation rate of athletes after injury was 12.90%.3.Influencing factors related to musculoskeletal injuries:(1)Influencing factors related to overall musculoskeletal injuries: higher PQSI score(OR=1.301,95% CI 1.051-1.609,P<0.05),higher frequency of drinking functional drinks(OR=6.603,95% CI 1.669-25.971,P<0.01)were overall musculoskeletal injuries;having an exercise habit(OR=0.206,95% CI0.056-0.758,P<0.05),greater BMI score(OR=0.133,95% CI 0.026-0.690,P<0.05),and higher resting systolic blood pressure(OR=0.888,95% CI 0.819-0.963,P<0.01)were protective factors associated with overall musculoskeletal injuries.(2)Influencing factors related to neck injury: increased daily training hours(OR=4.472,95% CI 1.209-16.544,P<0.05)was a risk factor related to neck injury.(3)Influencing factors related to wrist injury:increased number of years engaged in training(OR=8.909,95% CI 1.574-50.417,P<0.05)was a risk factor related to wrist injury.Backward sitting posture(OR=0.229,95% CI 0.059-0.890,P<0.05)and no fixed sitting posture(OR=0.193.95% CI 0.053-0.701,P<0.05)were protective factors associated with wrist injury.Conclusion:1.Mobile e Sports athletes had a high overall prevalence of musculoskeletal injuries(78.81%).Injuries were mainly found in the neck,lower back and fingers.Athletes’ musculoskeletal injuries were often multi-site injuries occurring simultaneously,and injury pain was predominantly mild.The e Sports athletes were less health conscious and had a lower rate of post-injury visits(12.9%).2.The results of this investigation show that having an exercise habit,a higher BMI within a certain range and increased resting systolic blood pressure are protective factors associated with the occurrence of overall musculoskeletal injuries in mobile e Sports athletes,and that higher frequency of functional drink consumption and PSQI scores were risk factors associated with the occurrence of musculoskeletal injuries.Longer daily training hours were an associated risk factor for neck injury.Increased years of training in the e Sports profession and the use of forward sitting during training were associated risk factors for wrist injury.3.Mobile e Sports athletes had a higher percentage of people with a BMI rating of underweight.Poor sleep quality is common among e Sports athletes.The mobile e Sports athletes of our country have longer daily training hours than foreign e Sports athletes.E-sports athletes are less physically active and athletes generally lack daily exercise habits. |
