The Roller Skating Athletes During The Pre-competition Training Health Management

Objective: Based on the studying of electrocardiogram, body composition andbiochemical indexes of urine and saliva of college roller skating athletes before the competition,as well as providing health management including massage, hot compress and nutritionguidance, achieve the optimal body state of the athletes.Method: The basic information collected from the roller skating athletes before thecompetition. Electrocardiogram and body composition are monitored once seven days.Additionally, morning urine is collected to test creative kinase and lactate dehydrogenaseactivity, as well as to measure values of hydroxyproline, urinary protein, uric acid content andurine PH. Moreover, saliva is tested for its pH value. Condition of myalgia is asked from theathletes on daily bases. According to the results of previously mentioned monitoring, healthmanagement including massage, hot compress and nutrition guidance is providedcorrespondingly.Results: (1) Body composition change: Protein level is significantly higher after 16 daysof training before the competition (P<0.01). Under the health management intervention, theprotein level is lowered (P<0.01). There is no obvious change in the varying pattern among thebody fat content, skeletal muscle content and body water content. The content is lower thanresults previous obtained, but is statistically insignificant. (2)The cardiac cycle: is significantlyreduced after 16 days of training compared to right before the competition (P<0.01). Underhealth management, there is no difference between the data obtained after 24 days of trainingand right before the competition (P>0.05). However, the cardiac cycle is improved obviouslyafter 24 days of training compared to 16 days.(3)Urine change: The varying pattern of urinaryprotein and hydroxyproline is similar, as shown by the increase after 8 days of training andsignificant increase after 16 days of training compared to right before the competition (P<0.01).The hydroxyproline level in urine has no obvious change compared to right before thecompetition, but urinary protein level changes (P<0.05). Uric acid level in urine shows adecreasing trend after training. After 16 days of training, the level of uric acid changessignificantly compared to right before competition (P<0.05). After health intervention, the uricacid level increased again. There is significant difference between 24 days of training and rightbefore the competition (P<0.01). The varying pattern of lactate dehydrogenase and creatinekinase is similar. The level in urine increased significantly after 16 days of training (P<0.05).Health intervention in implemented subsequently, the level decreased significantly after 24 days of training, compared to that of 16 days of training (P<0.05). (4) body fluid PH value: urine pHvalue increases significantly after 16 days of training (P<0.01). Compared 16 days of trainingand 24 days of training, urine pH value decreased significantly (P<0.01). Saliva pH value isweak acidic after 16 days of training compared to right before the competition, the change issignificant (P<0.01). Under health intervention, the value increased after 24 days of trainingcompared to right before competition (P<0.05).(5) Myalgia index: according to the healthinterview before the competition, there is no conditions of myalgia until 8 days of training. Thecondition of myalgia developed significantly after 16 days of training. Under one week ofhealth management, the condition of myalgia is eased off.(6) The results of the competition:athletes in the competition has made outstanding achievements. They got the second place inthe women’s 3000 meters relay race, won the fourth in the men’s 3000 meters relay race andshared no.8 in the 1000 meters and the 300 meters individual time trial.Conclusion: (1)According the results of monitoring and managing the biochemicalconditions of roller skating athletes before the competition, myalgia appears after 8 days oftraining, and various indexes proved the state of exercise-induced sport fatigue after 16 days oftraining, accompanied with micro injury to skeletal muscles. Using massage, heat compress andnutrition guidance as methods of health intervention, the fatigue condition can be improvedeffectively and create certain protective effect for skeletal muscles. (2) It is easy and effective tomonitor the body condition of the athletes before the competition using non-destructivemethods like analyzing urine and saliva. This also provide basis for regulations before thecompetition.
