Research On Training Monitoring Of Guangdong Elite Baseball Athletes During Winter Training

Purpose: Baseball has a long history,it is a player's personal technology,the overall tactical,physical quality,psychological characteristics,special intelligence are demanding movement.In China,the mass base of baseball is poor,and the scientific research and monitoring system is not systematic.To investigate the monitoring methods of sport physiology and biochemical index in elite baseball athletes during winter training.Methods: 24 elite baseball athletes(Age: 21.7±4.25 yrs,Height: 180.8±5.28 cm,Weight: 78.5±8.60kg)were summoned in the winter training to have a longitude observation and data accumulation.Hemoglobin,blood urea,creatine kinase,testosterone and cortisol were assayed to monitor and evaluate the training adaptation during the winter training.Meanwhile,body components of athletes were tested by InBody 3.0.The anaerobic power of lower limbs was measured by Monark984 E power bicycle in Sweden,and the real time heart rate was measured by using the Polar exercise heart rate monitoring system in Finland.The special strength of the pitcher was tested by the Swiss Con-Trex isokinetic testing system and the United States AMTI.All the data were collected and analyzed by SPSS11.5.Results:(1)It's found that there were descending tendency in HB and T and ascending tendency in CK and BUN while workout load and intensity ascended.(2)T was a high sensitivity and high specificity index for training load and suitable for physiological and biochemical monitoring of baseball.(3)Fat rate and WHR of Beijing elite baseball athletes were less than mean value of national elite male athletes,meanwhile lean body weight and BMI were higher than mean value of national elite male athletes.(4)After winter training,the athletes body fat ratio decreased,anaerobic peak power has been improved,the athletes lower limb ATP-CP energy supply system,power level has been a good development,has significantly improved.However,the average anaerobic power decreased,the rate of anaerobic power increased,and the endurance and endurance of the athletes were decreased.(5)The Guangdong outstanding pitcher in the specific strength of the diagnosis is attempted,because of individual differences,each athlete performance is different,but the overall lower limb base strength,explosive force,special forces requirements through testing are described,and the force model of the entire baseball pitching process is described.
