Abstract: This study through the literature material law, interview survey method, mathematical statistics method and inductive method and logic analysis, Chen was discussed from multiple perspectives for the London Olympic Games before the \"high in low practice\" mode of altitude training and monitoring arrangement, the study found: Chen altitude training plan time before the London games lasted 82 days, much longer than traditional pre-match training schedule. Each stage of training task clear, tight cohesion; Before the training program content mainly includes: physical stamina training, technical training, tactical training and recovery training four parts. Closely revolves around the Olympic Games the training content, physical training focus on basic athletic training and improving athletes, tactical training emphasis on practical, throughout the lesson focus time, highlights the importance of technical training; Attaches great importance to the grade of different intensity endurance training, diversification of means; Load arrangement is negatively related to the intensity of load and load training patterns; Before the basic within the normal range, physiological and biochemical index volatility is smaller. Can reflect the timely and effective training load, especially heavy load training after the body function condition, is advantageous to the coaches and scientific researchers to adjust athletes functional status.

Key words: Chen Ding, The London Olympic Games, Per-competition Altitude Training and Monitoring
