Study on Training Loads of Elite Sprinter ZHANG Pei-meng in Preparation

Objective:To explore ZHANG Pei-meng's pre-competition training practices in preparation for the 2013 Moscow World Championships in Athletics. Methods:Through the methodology of field work, this paper collected ZHANG Pei-meng's training load characteristics, and combining the monitoring of physiological and biochemical indicators, evaluated the physiological state of ZHANG Pei-meng's pre-competition training before Moscow World Championships. Results:ZHANG Peimeng started the pre-competition training 7 weeks before the Moscow World Championships in Athletics, the main characteristic of ZHANG's pre-competition training was pre-competition tapering. ZHANG's aerobic endurance, speed endurance, and reactive force training volume decreased, while his maximal strength and speed training volume increased. ZHANG's total training volume decreased by 20% with a progressive non-linear pattern. During pre-competition training, ZHANG's serum creatine kinase and blood urea nitrogen concentrations demonstrated a downward trend and reached 243 IU/L and 5.56 mmol/L, respectively. Testosterone levels and the testosterone:cortisol ratio demonstrated an upward trend and reached 888 ng/dL and 40.73, respectively. His hemoglobin level peaked before the competition, while his red blood cell count, hematocrit, white blood cell count, and platelet count remained in the normal range. These data demonstrated that ZHANG was in his optimal physiological state prior to competition. Conclusion:A 7-week pre-competition training makes great contributions to ZHANG Pei-meng's optimal performance at 2013 Moscow World Championships in Athletics
